S-3 THE CORPORATION On May 15, 2003, we completed a reorganization (pursuant to a statutory plan of arrangement) whereby we became a wholly-owned subsidiary of a new holding company, TransCanada Corporation. Pursuant to this arrangement, each of our issued and outstanding common shares was exchanged for one common share of TransCanada Corporation. We operate primarily in two business segments: Gas Transmission and Power. The Gas Transmission segment of our business includes the operation of the Alberta System, the Canadian Mainline, the Foothills System and the BC System. The Gas Transmission segment also includes our other investments in natural gas pipelines located in Canada and the United States. The Power segment of our business includes the construction, ownership, operation and management of power plants and the marketing of electricity and provides electricity account services to energy and industrial customers. The Power segment operates in Canada and the United States. Our significant subsidiaries as of December 31, 2003 are listed under the heading "The Company - Subsidiaries" to the Annual Information Form. Our registered office and executive offices are located at 450 - 1st Street S.W., Calgary, Alberta, Canada, T2P 5H1. S-4 RECENT DEVELOPMENTS On February 24, 2004 National Energy & Gas Transmission, Inc. ("NEGT") and TransCanada Corporation ("TCC") announced an agreement for us to acquire, through one of our wholly-owned subsidiaries, Gas Transmission Northwest Corporation ("GTN") for US$1.703 billion, including US$500 million of assumed debt and subject to typical closing adjustments. GTN is a natural gas pipeline company that owns and operates two pipeline systems. The main system consists of more than 1,350 miles (2,174 kilometres) of pipeline extending from a point near Kingsgate, British Columbia, on the British Columbia-Idaho border, to a point near Malin, Oregon on the Oregon-California border. The natural gas transported on this pipeline originates primarily from supplies in Canada for customers located in the Pacific Northwest, Nevada and California. The other pipeline is an 80-mile (128-kilometre) system that extends from a point near Ehrenberg, Arizona to a point near Ogilby, California on the California-Baja California, Mexico border. The natural gas transported on this system comes primarily from supplies in the southwestern United States for markets in Northern Baja California, Mexico. The sale of the latter pipeline is subject to a right of first refusal by another company. Because NEGT voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in July 2003, the sale of GTN to us will be subject to bankruptcy court approval, and will include a court-sanctioned auction process in accordance with customary bidding procedures approved by the bankruptcy court. Under this auction, NEGT will seek offers that are higher or otherwise better than the one negotiated with TCC. As part of the agreement, TCC was granted certain protections, subject to court approval, most notably a break fee and expense reimbursement if another bid is accepted. TCC also retains the right to amend its offer should NEGT receive an offer which is superior to NEGT's existing agreement with TCC. The agreement contemplates that final bankruptcy court approval of the sale will be obtained within 75 days after signing of the agreement. The agreement is also subject to bankruptcy court approval of the NEGT Plan of Reorganization. Approval of NEGT's Plan could occur at a date later than the receipt of court approval of the sale. The sale is also subject to anti-trust review and the satisfaction of numerous closing conditions. S-5 SELECTED CONSOLIDATED FINANCIAL DATA The following table sets forth selected consolidated financial data and other data as at the dates or for the periods indicated. Our consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles ("Canadian GAAP"). The financial data should be read in conjunction with our consolidated financial statements and the related notes and Management's Discussion and Analysis included in the documents described under "Documents Incorporated by Reference" in this prospectus supplement.

We intend to use all of the net proceeds of this offering to repay outstanding indebtedness. Pending this use, the net proceeds may be invested in short-term marketable securities. EARNINGS COVERAGE The following financial ratios have been calculated on a consolidated basis for the 12 month period ended December 31, 2003 and are based on audited financial information. The following ratios give effect to the issue of the notes pursuant to this prospectus supplement as if the notes had been issued as of December 31, 2003. The financial ratios have been calculated based on financial information prepared in accordance with Canadian GAAP. -------------------------------------------------------------------------------- DECEMBER 31, 2003 -------------------------------------------------------------------------------- Based on net income including discontinued operations: Earnings coverage on long-term debt(1).................... times Based on net income from continuing operations: Earnings coverage on long-term debt(1).................... times -------------------------------------------------------------------------------- (1) The above ratios have been calculated without including the annual carrying charges relating to the equity component of the Corporation's outstanding preferred securities. If the equity component of the preferred securities were classified as debt as they would be under U.S. generally accepted accounting principles, the entire carrying charges of the preferred securities would be included in interest obligations. If these annual carrying charges had been included in the calculations, the earnings coverage on long-term debt based on net income including discontinued operations would have been times for the 12 month period ended December 31, 2003; and the earnings coverage on long-term debt based on net income from continuing operations would have been times for the 12 month period ended December 31, 2003. Our interest requirements on long-term debt, after giving effect to the issue of the notes to be distributed under this prospectus supplement, amounted to $ million for the 12 months ended December 31, 2003. Our net income including discontinued operations before interest and income tax for the 12 months ended December 31, 2003 was $2,359 million, which is times our pro forma interest requirement for this period; and our net income from continuing operations before interest and income tax for the 12 months ended December 31, 2003 was $2,280 million, which is times our pro forma interest requirement for this period. S-8 DESCRIPTION OF THE NOTES The notes will be issued under an amended and restated debt indenture, dated as of November 30, 2000, as supplemented or amended from time to time (the "Indenture"), between the Corporation and The Bank of New York, as Trustee. The following summary of certain provisions of the Indenture and the notes does not purport to be complete and is qualified in its entirety by reference to the actual provisions of the Indenture. The following description of the terms of the notes offered hereby supplements, and to the extent inconsistent therewith supersedes, the description of the general terms and provisions of debt securities set forth under the heading "Description of Debt Securities" in the accompanying prospectus, and should be read in conjunction with that description. GENERAL The trustee under the Indenture shall be referred to herein as the "Trustee", which term shall include, unless the context otherwise requires, its successors and assigns. Capitalized terms used but not defined herein shall have the meanings given to them in the Indenture. The term "debt securities", as used in this prospectus supplement, refers to all debt securities issued and issuable from time to time under the Indenture and includes the notes. The notes will be issued under the Indenture in a single series in an aggregate principal amount of US$ . The notes will mature on , 2034. The notes will bear interest at a rate of % per year. Interest will be payable semi-annually on and of each year, commencing , 2004, to the persons in whose names the notes are registered at the close of business on the preceding or , respectively. The principal and interest on the notes will be paid in lawful money of the United States in the manner and on terms set out in the Indenture. We may from time to time without notice to, or the consent of, the holders of the notes, create and issue additional notes under the Indenture, equal in rank to the notes in all respects so that the new notes may be consolidated and form a single series with the notes and have the same terms as to status, redemption and otherwise as the notes issued under this prospectus supplement. The notes will be direct unsecured obligations of the Corporation, issued under the Indenture and will rank equally with all other unsecured and unsubordinated indebtedness of the Corporation other than preferred claims imposed by statute. In addition, our business operations are conducted in part through our subsidiaries and through joint ventures. As a result, the notes will be effectively subordinated to all existing and future liabilities of our subsidiaries and joint ventures. As at December 31, 2003, the long-term debt (excluding guarantees and intercompany obligations between the Corporation and its subsidiaries) of the Corporation's wholly-owned subsidiaries totaled approximately $2.336 billion. At December 31, 2003, as determined under Canadian GAAP, the Corporation's total consolidated long-term debt, long-term debt due within one year and amount of outstanding preferred securities and junior subordinated debentures was, in aggregate principal amount, approximately $10.037 billion (excluding the Corporation's proportionate share of non-recourse debt of joint ventures). There are no terms of the Indenture that limit the ability of the Corporation or its subsidiaries or joint ventures to incur additional indebtedness, including in the case of the S-9 Corporation and its subsidiaries and joint ventures, indebtedness that ranks, either effectively or by contract, senior to the notes. See "Description of Debt Securities - Unsubordinated Debt" and "Description of Debt Securities - Certain Covenants of the Corporation" in the accompanying prospectus. The notes will be denominated in United States dollars and payments of principal (and premium, if any) and interest on the notes will be made in United States dollars. The notes will not be entitled to any benefits of a sinking fund. OPTIONAL REDEMPTION The notes will be redeemable, in whole or in part, at our option at any time or from time to time at a redemption price equal to the greater of: - 100% of the principal amount of the notes to be redeemed, and - as determined by the Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed (not including any portion of the payments of interest accrued as of the date of redemption), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) plus basis points, plus, in either case, accrued interest thereon to the date of redemption. Notice of any redemption will be delivered by first-class mail at least 30 days, but not more than 60 days, before the redemption date to each holder of the notes to be redeemed. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions of the notes called for redemption. "ADJUSTED TREASURY RATE" means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the redemption date. "COMPARABLE TREASURY ISSUE" means the United States Treasury security or securities selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes. "COMPARABLE TREASURY PRICE" means, with respect to any redemption date, (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. "QUOTATION AGENT" means one of the Reference Treasury Dealers, which is appointed by the Trustee after consultation with us. S-10 "REFERENCE TREASURY DEALER" means JPMorgan plus four others or their affiliates which are primary U.S. Government securities dealers and their respective successors, provided, however, that if any of the foregoing or their affiliates shall cease to be a primary U.S. Government securities dealer in New York City (a "Primary Treasury Dealer"), we shall substitute another Primary Treasury Dealer. "REFERENCE TREASURY DEALER QUOTATIONS" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 3:30 p.m. (New York time) on the third business day preceding such redemption date. PAYMENT OF PRINCIPAL AND INTEREST Payments of principal of, and premium, if any, and interest on, the notes will be made by the Corporation through the Trustee to the Depositary (as defined below). See "Description of the Notes - Book-Entry System". "BUSINESS DAY" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York. Interest payments for the notes will include accrued interest from and including the date of issue or from and including the last date in respect of which interest has been paid, as the case may be, to, but excluding, the interest payment date or the date of maturity, as the case may be. If any interest payment date or the maturity date of the notes falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be postponed to the next succeeding Business Day, and no interest on such payment will accrue for the period from and after such interest payment date or the maturity date, as the case may be. BOOK-ENTRY SYSTEM The notes will be represented by one or more fully registered global securities (the "Global Securities") registered in the name of Cede & Co. (the nominee of The Depository Trust Company (the "Depositary")), or such other name as may be requested by an authorized representative of the Depositary. The authorized denominations of each note will be US$1,000 and integral multiples thereof. The provisions set forth under "Description of Debt Securities - Global Securities" in the accompanying prospectus will be applicable to the notes. Accordingly, notes may be transferred or exchanged only through the Depositary and its participants. Except as described under "Description of Debt Securities - Global Securities" in the accompanying prospectus, owners of beneficial interests in the Global Securities will not be entitled to receive notes in definitive form. Each person owning a beneficial interest in a Global Security must rely on the procedures of the Depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest in order to exercise any rights of a holder under the Indenture. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. Such limits and such laws may impair the ability to transfer beneficial interests in a Global Security representing the notes. S-11 The following is based on information furnished by the Depositary: The Depositary is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities that its participants ("Participants") deposit with the Depositary. The Depositary also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants' accounts, thereby eliminating the need for physical movement of securities certificates. These direct Participants ("Direct Participants") include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. The Depositary is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. Access to the Depositary's system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). The rules applicable to the Depositary and its Participants are on file with the Securities and Exchange Commission. Purchases of the notes under the Depositary's system must be made by or through Direct Participants, which will receive a credit for such notes on the Depositary's records. The ownership interest of each actual purchaser of each note represented by a Global Security ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from the Depositary of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in a Global Security representing notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners of a Global Security representing the notes will not receive notes in definitive form representing their ownership interests therein, except in the event that use of the book-entry system for such notes is discontinued. To facilitate subsequent transfers, the Global Securities representing the notes which are deposited with the Depositary are registered in the name of the Depositary's nominee, Cede & Co., or such other name as may be requested by an authorized representative of the Depositary. The deposit of Global Securities with the Depositary and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the Global Securities representing the notes; the Depositary's records reflect only the identity of the Direct Participants to whose accounts such notes are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by the Depositary to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. S-12 Neither the Depositary nor Cede & Co. (nor such other nominee of the Depositary) will consent or vote with respect to the Global Securities representing the notes. Under its usual procedures, the Depositary mails an "omnibus proxy" to the Corporation as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the notes are credited on the applicable record date (identified in a listing attached to the omnibus proxy). Principal, premium, if any, and interest payments on the Global Securities representing the notes will be made to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary). The Depositary's practice is to credit Direct Participants' accounts, upon the Depositary's receipt of funds and corresponding detailed information from the Corporation or the applicable Trustee, on the applicable payment date in accordance with their respective holdings shown on the Depositary's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of such Participant and not of the Depositary, the applicable Trustee or the Corporation, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary) is the responsibility of the Corporation or the applicable Trustee, disbursement of such payments to Direct Participants shall be the responsibility of the Depositary, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants. The Depositary may discontinue providing its services as securities depository with respect to the notes at any time by giving reasonable notice to the Corporation or the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, notes in definitive form are required to be printed and delivered to each holder. The Corporation may decide to discontinue use of the system of book-entry transfers through the Depositary (or a successor securities depository). In that event, notes in definitive form will be printed and delivered. The information in this section concerning the Depositary and the Depositary's book-entry system has been obtained from sources that the Corporation believes to be reliable, but is subject to any changes to the arrangements between the Corporation and the Depositary and any changes to such procedures that may be instituted unilaterally by the Depositary. S-13 CERTAIN INCOME TAX CONSIDERATIONS CERTAIN UNITED STATES INCOME TAX CONSIDERATIONS The following is a general summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of the notes by U.S. Holders (as defined below). The summary is for general information only and is based on the U.S. Internal Revenue Code of 1986, as amended (the "Code"), the Treasury regulations promulgated or proposed thereunder, and judicial and administrative interpretations thereof, all as in effect on the date hereof and all of which are subject to change (possibly with retroactive effect). The tax treatment of a holder of the notes may vary depending upon the particular situation of the holder. Certain holders (including, but not limited to, insurance companies, tax-exempt organizations, financial institutions, persons subject to the alternative minimum tax, U.S. persons whose functional currency is not the U.S. dollar, holders that are not U.S. Holders, traders in securities that elect mark-to-market accounting treatment, broker-dealers in securities or holders who will hold the notes as a hedge against currency risks or as part of a straddle, synthetic security, conversion transaction, or other integrated investment comprised of the notes and one or more other investments) may be subject to special rules not discussed below. The following summary is applicable only to purchasers of the notes on original issue at the issue price and does not address other purchasers. In addition, the summary is limited to investors who will hold the notes as "capital assets" within the meaning of Section 1221 of the Code. The discussion below also does not address the effect of any state, local or non-U.S. law on a holder of the notes. As used herein, the term "U.S. Holder" means an individual who is a citizen or resident of the United States, a corporation or other entity treated as a corporation for U.S. federal income tax purposes organized in or under the laws of the United States, any state thereof, or the District of Columbia, an estate that is subject to U.S. federal income taxation without regard to the source of its income, or a trust if, in general, a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or the trust has elected to be treated as a U.S. person. If a partnership (including for this purpose any other entity, organized within or without the United States, treated as a partnership for U.S. federal income tax purposes) holds notes, the tax treatment of a partner as beneficial owner of notes generally will depend on the status of the partner and the activities of the partnership. The summary does not constitute, and should not be considered as, legal or tax advice to holders of notes. Each holder of the notes should consult a tax advisor as to the particular tax consequences to such holder of holding the notes, including the applicability and effect of any state, local or foreign tax laws. PAYMENTS OF INTEREST Interest on a note will be taxable to a U.S. Holder as ordinary interest income at the time it is accrued or is received in accordance with the U.S. Holder's method of accounting for U.S. federal income tax purposes. Interest on the notes will constitute income from sources without the United States and generally will be treated as "passive" or "financial services" income for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws. S-14 SALE AND RETIREMENT OF THE NOTES A U.S. Holder will recognize a gain or loss on the sale or retirement of a note equal to the difference between the amount realized on the sale or retirement (except to the extent of accrued and unpaid interest, which will be taxable as such) and the U.S. Holder's tax basis in the note (generally, the price the U.S. Holder paid for the note). As a general rule, such gain or loss recognized on the sale or retirement of a note will be capital gain or loss and will be long-term capital gain or loss if the note was held for more than one year. Such income or loss will constitute income or loss from sources within the United States for purposes of computing the foreign tax credit allowable under the U.S. federal income tax laws. For noncorporate U.S. Holders, including individuals, the excess of net long-term capital gains over net short-term capital losses generally is taxed at a lower rate (currently at a maximum rate of 15%) than ordinary income. The deductibility of capital losses is subject to limitation. BACKUP WITHHOLDING A U.S. Holder of a note may be subject to backup withholding (currently at a rate of 28%) with respect to payments of principal and interest made on the note, or the proceeds of a sale or exchange of the note before maturity, unless such U.S. Holder (a) is a corporation or comes within certain other exempt categories and, when required, certifies to this fact or (b) provides a U.S. taxpayer identification number, certifies that such U.S. Holder is not subject to backup withholding, and otherwise complies with applicable requirements of the backup withholding rules. A U.S. Holder of a note that does not provide us with a correct U.S. taxpayer identification number or an adequate basis for exemption may be subject to penalties imposed by the Internal Revenue Service. The backup withholding tax is not an additional tax and will be credited against a U.S. Holder's U.S. federal income tax liability, provided the required information is furnished to the Internal Revenue Service. CERTAIN CANADIAN INCOME TAX CONSIDERATIONS The following is, as of the date hereof, a general summary of the principal Canadian federal income tax considerations under the INCOME TAX ACT (Canada) (the "Tax Act") applicable to a purchaser of notes pursuant to the prospectus and this prospectus supplement who, at all relevant times, for purposes of the Tax Act and any applicable tax treaty, is not resident or deemed to be resident in Canada, deals with the Corporation at arm's length and does not use or hold and is not deemed to use or hold a note in carrying on business in Canada (a "Non-Resident Holder"). This summary is based on the current provisions of the Tax Act and the regulations thereunder, proposed amendments to the Tax Act and the regulations thereunder publicly announced prior to the date of this prospectus supplement (the "Proposed Amendments") and on counsel's understanding of the current administrative practices of the Canada Customs and Revenue Agency in effect as of the date hereof. This summary is not exhaustive of all possible Canadian federal income tax considerations applicable to a Non-Resident Holder and does not anticipate any changes in law or administrative practice, nor does it take into account provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein. Special rules, which are not discussed below, may apply to a non-resident that is an insurer which carries on business in Canada and elsewhere. S-15 This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular holder, and no representations with respect to the income tax consequences to any particular holder are made. Accordingly, prospective purchasers of notes should consult their own tax advisors for advice with respect to the tax consequences to them of acquiring, holding and disposing of notes. Under the Tax Act the payment of interest, principal or premium, if any, to a Non-Resident Holder of a note will be exempt from Canadian non-resident withholding tax. No other taxes on income or capital gains will be payable under the Tax Act in respect of the acquisition, holding, redemption or disposition of a note by a Non-Resident Holder, or the receipt of interest, principal or premium thereon by a Non-Resident Holder solely as a consequence of such acquisition, holding, redemption or disposition of a note. EACH OF THESE SUMMARIES UNDER THIS SECTION "CERTAIN INCOME TAX CONSIDERATIONS" IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR HOLDER AND NO REPRESENTATION IS MADE WITH RESPECT TO THE U.S. FEDERAL TAX CONSEQUENCES OR CANADIAN TAX CONSEQUENCES TO ANY PARTICULAR HOLDER. ACCORDINGLY, PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE U.S. FEDERAL TAX CONSEQUENCES OR CANADIAN TAX CONSIDERATIONS RELEVANT TO THEM, HAVING REGARD TO THEIR PARTICULAR CIRCUMSTANCES. S-16 CREDIT RATINGS The notes have been rated A- by Standard & Poor's ("S&P") A2 by Moody's Investors Service, Inc. ("Moody's") and A by the Dominion Bond Rating Service Limited ("DBRS") (S&P, Moody's and DBRS are each a "Rating Agency"). The rating outlook from each of Moody's and DBRS is stable and the rating outlook from S&P is negative. Credit ratings are intended to provide investors with an independent measure of credit quality of an issue of securities. The Rating Agencies' ratings for debt instruments range from a high of AAA to a low of D for both S&P and DBRS and, in the case of Moody's long-term issuer rating, from a high of Aaa to a low of C. According to the S&P rating system, an obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitment on the obligation is still strong. The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories. According to the Moody's rating system, debt securities rated A possess many favorable investment attributes and are to be considered as upper-medium-grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment sometime in the future. Numerical modifiers 1, 2 and 3 are applied to each rating classification from Aa through Caa, with 1 indicating that the obligation ranks in the higher end of the category, 2 indicating a mid-range ranking and 3 indicating a ranking in the lower end of the category. According to the DBRS rating system, debt securities rated A are of satisfactory credit quality. Protection of interest and principal is still substantial, but the degree of strength is less than with AA rated entities. While a respectable rating, entities in the A category are considered to be more susceptible to adverse economic conditions and have greater cyclical tendencies than higher rated companies. "High" or "low" grades are used to indicate the relative standing within a rating category. The credit ratings accorded to the notes by the Rating Agencies are not recommendations to purchase, hold or sell the notes inasmuch as such ratings do not comment as to market price or suitability for a particular investor. There is no assurance that any rating will remain in effect for any given period of time or that any rating will not be revised or withdrawn entirely by a Rating Agency in the future if, in its judgment, circumstances so warrant. The lowering of any rating of the notes may negatively affect the quoted market price, if any, of the notes. S-17 UNDERWRITING JPMorgan is acting as representative of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of notes set forth opposite the underwriter's name. -------------------------------------------------------------------------------- PRINCIPAL AMOUNT UNDERWRITER OF NOTES ---------------------------------------------------------------------------------- J.P. Morgan Securities Inc.................................. US$ Citigroup Global Markets Inc................................ Deutsche Bank Securities Inc................................ HSBC Securities (USA) Inc................................... Banc One Capital Markets, Inc............................... SG Cowen Securities Corporation............................. Lazard Freres & Co. LLC..................................... -------------------- Total..................................................... US$ ---------------------------------------------------------------------------------- The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes. The underwriters propose to offer some of the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the notes to dealers at the public offering price less a concession not to exceed % of the principal amount of the notes. The underwriters may allow, and dealers may reallow a concession not to exceed % of the principal amount of the notes on sales to other dealers. After the initial offering of the notes to the public, the representative may change the public offering price and concessions. The following table shows the underwriting commission that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes). -------------------------------------------------------------------------------- PAID BY THE CORPORATION ------------------------------------------------------------------------- Per note.................................................... % ------------------------------------------------------------------------- In connection with the offering, JPMorgan, on behalf of the underwriters, may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order S-18 to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when JPMorgan, in covering syndicate short positions or making stabilizing purchases, repurchases notes originally sold by that syndicate member. Any of these activities may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. We have been advised that the underwriters may make a market in the notes but are not obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. We estimate that our total expenses for this offering will be US$ . The underwriters have performed investment banking and advisory services for us from time to time for which they have received customary fees and expenses. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business. JPMorgan and the other underwriters will make the securities available for distribution on the Internet through a proprietary Web site and/or a third-party system operated by Market Axess Inc., an Internet-based communications technology provider. Market Axess Inc. is providing the system as a conduit for communications between JPMorgan, the other underwriters and their customers and is not a party to any transactions. Market Axess Inc., a registered broker-dealer, will receive compensation from JPMorgan and the other underwriters based on transactions such parties conduct through the system. JPMorgan and the other underwriters will make the securities available to their customers through the Internet distributions, whether made through a proprietary or third-party system, on the same terms as distributions made through other channels. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make because of any of those liabilities. Lazard Freres & Co. LLC ("Lazard") has entered into an agreement with Mitsubishi Securities (USA), Inc. ("Mitsubishi") pursuant to which Mitsubishi provides certain advisory and/or other services to Lazard, including in respect of this offering. In return for the provision of such services by Mitsubishi to Lazard, Lazard will pay to Mitsubishi a mutually agreed upon fee. S-19 Under applicable Canadian securities legislation, we may be considered to be a connected issuer of JPMorgan, Citigroup Global Markets Inc., Deutsche Bank Securities Inc., HSBC Securities (USA) Inc., Banc One Capital Markets, Inc., SG Cowen Securities Corporation and Mitsubishi, each of which is a subsidiary or affiliate of a bank which is a lender to the Corporation under an undrawn $1.5 billion credit facility. We are also a guarantor under an undrawn US$50 million demand operating line of credit provided by one of these lenders to one of our subsidiaries. The Corporation is not in default under such credit facilities. None of the lenders were involved in the decision to offer the notes or the determination of the terms of distribution of the notes.

The specific terms of any offering of debt securities will be set forth in a shelf prospectus supplement (a "Prospectus Supplement") including, where applicable the specific designation of the debt securities, any limit on the aggregate principal amount of the debt securities, the currency, the maturity, the offering price, whether payment on the debt securities will be senior or subordinated to the Corporation's other liabilities and obligations, whether the debt securities will bear interest, the interest rate or method of determining the interest rate, any terms of redemption, any conversion or exchange rights and any other specific terms. A Prospectus Supplement may include other specific terms pertaining to the debt securities that are not prohibited by the parameters set forth in this prospectus.

TransCanada may sell the debt securities to or through underwriters or dealers purchasing as principals and may also sell the debt securities to one or more purchasers directly or through agents. See "Plan of Distribution". The Prospectus Supplement relating to a particular offering of debt securities will identify each underwriter, dealer or agent, as the case may be, engaged by TransCanada in connection with the offering and sale of the debt securities, and will set forth the terms of the offering of such debt securities, including the method of distribution of such debt securities, the proceeds to TransCanada and any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution. Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of debt securities will be a new issue of debt securities with no established trading market. The debt securities may be sold from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a non-fixed price basis the debt securities may be offered at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers, in which case the compensation payable to any underwriter, dealer or agent in connection with any such sale will be the amount, if any, by which the aggregate price paid for the debt securities by the purchasers exceeds the gross proceeds paid by the underwriter, dealer or agent to the Corporation and the price at which the debt securities will be offered and sold may vary as between purchasers during the distribution period. There is currently no market through which the debt securities may be sold and purchasers may not be able to resell such securities issued under this prospectus.

FORWARD-LOOKING STATEMENTS This prospectus (and any Prospectus Supplement) and the documents incorporated by reference in this prospectus (and in any Prospectus Supplement) include "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words like "believes", "intends", "expects", "may", "will", "should", or "anticipates", or the negative equivalents of those words or comparable terminology, and by discussions of strategies that involve risks and uncertainties. Given the risks and uncertainties of the Corporation's business, including those discussed and incorporated by reference in this prospectus under "Risk Factors", actual results may differ materially from those expressed or implied by forward-looking statements. In addition, the Corporation bases forward- looking statements on assumptions about future events, which may not prove to be accurate. In light of these risks, uncertainties and assumptions, prospective investors should be aware that the forward-looking statements described in this prospectus (and in any Prospectus Supplement) and the documents incorporated by reference in this prospectus (and in any Prospectus Supplement) may not occur. The Corporation cannot assure prospective investors that its future results, levels of activity and achievements will occur as the Corporation expects, and neither the Corporation nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. The Corporation has no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. 4 THE CORPORATION On May 15, 2003, the Corporation completed a reorganization (pursuant to a statutory plan of arrangement) whereby it became a wholly owned subsidiary of a new holding company, TransCanada Corporation. Pursuant to this arrangement, each issued and outstanding common share of the Corporation was exchanged for one common share of TransCanada Corporation. The Corporation operates primarily in two business segments: Transmission and Power. The Transmission segment of TransCanada's business includes the operation of the Alberta System, the Canadian Mainline and the BC System. The Transmission segment also includes TransCanada's other investments in natural gas pipelines located in Canada and the United States. The Power segment of TransCanada's business includes the construction, ownership, operation and management of power plants and the marketing of electricity and provides electricity account services to energy and industrial customers. The Power segment operates in Canada and the northern tier of the United States. The significant subsidiaries of TransCanada as of December 31, 2002 are listed in Schedule A to the Annual Information Form. TransCanada's registered office and executive office are located at 450 - 1st Street S.W., Calgary, Alberta, Canada, T2P 5H1. USE OF PROCEEDS Unless otherwise specified in a Prospectus Supplement, the net proceeds from the sale of debt securities will be used for general corporate purposes, including the repayment of indebtedness and the financing of the Corporation's long-term investment plan. The amount of net proceeds to be used for any such purpose will be set forth in a Prospectus Supplement. The Corporation may, from time to time, issue securities other than pursuant to this prospectus. EARNINGS COVERAGE The following financial ratios have been calculated on a consolidated basis for the respective 12 month periods ended December 31, 2002 and March 31, 2003 and are based on audited financial information, in the case of the 12 month period ended December 31, 2002, and unaudited financial information, in the case of the 12 month period ended March 31, 2003. The following ratios do not give effect to the issue of any debt securities pursuant to this prospectus and any Prospectus Supplement. The financial ratios have been calculated based on financial information prepared in accordance with Canadian generally accepted accounting principles. The following ratios have been prepared based on net income: MARCH 31, DECEMBER 31, 2003 2002 ---------- ------------- Earnings coverage on long-term debt(1)...................... 2.55 times 2.45 times ------------ NOTE: (1) The above ratios have been calculated without including the annual carrying charges relating to the equity component of TransCanada's outstanding preferred securities. If the equity component of the preferred securities were classified as debt, the entire carrying charges of the preferred securities would be included in interest obligations. If these annual carrying charges had been included in the calculations, the earnings coverage on long-term debt would have been 2.40 times for the 12 month period ended March 31, 2003 and 2.31 times for the 12 month period ended December 31, 2002. DESCRIPTION OF DEBT SECURITIES The debt securities will rank PARI PASSU, except as to sinking funds, with all other unsecured and unsubordinated debt of the Corporation ("Unsubordinated Debt Securities") or debt securities that will be subordinate and junior in right of payment to all Senior Indebtedness (as defined below) of the Corporation ("Subordinated Debt Securities"). The debt securities will be issued, in the case of Unsubordinated Debt Securities, under an amended and restated debt indenture, as supplemented or amended from time to time (the "Debt Indenture"), between the Corporation and The Bank of New York, as Trustee, and, in the 5 case of Subordinated Debt Securities under an amended and restated subordinated debt indenture, as supplemented or amended from time to time (the "Subordinated Debt Indenture"), between the Corporation and The Bank of Nova Scotia Trust Company of New York, as Trustee. The Debt Indenture and the Subordinated Debt Indenture are sometimes hereinafter referred to individually as an "Indenture" and collectively as the "Indentures". The Bank of New York and The Bank of Nova Scotia Trust Company of New York are hereinafter referred to individually as a "Trustee" and collectively as the "Trustees". The following summaries of certain provisions of the Indentures and the debt securities do not purport to be complete and such summaries are subject to the detailed provisions of the applicable Indenture to which reference is hereby made for a full description of such provisions, including the definitions of certain terms used herein, and for other information regarding the debt securities. Numerical references in parentheses below are to sections in the applicable Indenture. Wherever particular sections or defined terms of the applicable Indenture are referred to, such sections or defined terms are incorporated herein by reference as part of the statement made, and the statement is qualified in its entirety by such reference. The Indentures are substantially identical, except for the provisions relating to subordination and certain covenants. See "Subordinated Debt" and "Certain Covenants of the Corporation". The debt securities offered by this prospectus and the related Prospectus Supplement are referred to herein as the "Offered Debt Securities". As used under this caption, the term "Corporation" means TransCanada PipeLines Limited, and does not include the subsidiaries of TransCanada PipeLines Limited through which particular business operations are conducted. GENERAL Neither of the Indentures limits the amount of the debt securities, debentures, notes or other evidences of indebtedness that may be issued by the Corporation or any of its subsidiaries. The debt securities will be unsecured and either unsubordinated or subordinated obligations of the Corporation. The Corporation has outstanding First Mortgage Pipe Line Bonds ("First Mortgage Pipe Line Bonds") issued under a Deed of Trust and Mortgage dated as of January 1, 1957, as amended and supplemented from time to time (the "Mortgage"), which are secured by the Corporation's present and future Canadian mainline assets and gas transportation contracts. The holders of First Mortgage Pipe Line Bonds have a secured claim on such assets which is prior to the unsecured claim that holders of the debt securities may have on such assets. As of the date hereof, the aggregate outstanding principal amount of First Mortgage Pipe Line Bonds was approximately 25 million Pounds Sterling. The Indentures provide that debt securities may be created and issued from time to time in one or more series. Reference must be made to the Prospectus Supplement for specific terms of and information relating to the Offered Debt Securities (to the extent such terms are applicable to such debt securities) including the following: (i) classification as Unsubordinated Debt Securities or Subordinated Debt Securities, the specific designation, aggregate principal amount, purchase price and denominations, if other than U.S. $1,000; (ii) any date of maturity; (iii) interest rate or rates (or the method by which such rate or rates will be determined), if any; (iv) the dates on which any such interest will be payable; (v) the place or places, if any, other than or in addition to the Borough of Manhattan, The City of New York, where the principal of, premium, if any, and interest, if any, on the Offered Debt Securities will be payable; (vi) any redemption, repayment or sinking funds provisions; (vii) any applicable United States federal income tax consequences, including whether and under what circumstances the Corporation will pay additional amounts on Offered Debt Securities held by a person who is not a United States person in respect of any tax, assessment or governmental 6 charge withheld or deducted and, if so, whether the Corporation will have the option to redeem such Offered Debt Securities rather than pay such additional amounts; (viii) the portion of the principal amount of the Offered Debt Securities, if other than the principal amount thereof, payable upon acceleration of the maturity thereof; (ix) if other than United States dollars, the Currency (as defined below) in which payment of the principal of or interest, if any, on the Offered Debt Securities shall be payable or in which the Offered Debt Securities shall be denominated and the particular provisions applicable thereto; (x) whether the principal of and interest, if any, on the Offered Debt Securities are to be payable in a Currency other than that in which such Offered Debt Securities are denominated or stated to be payable, and other information, including the method of calculating the applicable exchange rate, related thereto; and (xi) any other specific terms of the Offered Debt Securities, including any additional events of default or covenants provided for with respect to such debt securities, and any terms which may be required by or advisable under applicable laws or regulations. "Currency" means any currency or currencies, composite currency or currency unit or units, issued by the government of one or more countries or by any recognized confederation or association of such governments. Debt securities will bear interest at a fixed rate ("Fixed Rate Security") or a floating rate ("Floating Rate Security"). Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate will be sold at a discount below their stated principal amount. Special United States federal income tax considerations applicable to any such discounted debt securities or to certain debt securities issued at par that are treated as having been issued at a discount for United States federal income tax purposes will be described in the relevant Prospectus Supplement. The Indentures provide that all accounting terms not specifically defined therein are to be construed in accordance with Canadian generally accepted accounting principles consistently applied. GLOBAL SECURITIES The debt securities of a series may be issued in the form of one or more fully registered global debt securities ("Registered Global Security") that will be deposited with The Depository Trust Company (the "Depositary") or with a nominee for the Depositary identified in the Prospectus Supplement relating to such series. In such case, one or more Registered Global Securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding registered debt securities of the series to be represented by such Registered Global Security or Securities. Unless and until it is exchanged for debt securities in definitive registered form, a Registered Global Security may not be transferred except as a whole by the Depositary for such Registered Global Security to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor of such Depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a Registered Global Security will be described in the Prospectus Supplement relating to such series. The Corporation anticipates that the following provisions will apply to all depositary arrangements. Upon the issuance of a Registered Global Security, the Depositary for such Registered Global Security will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by such Registered Global Security to the accounts of persons that have accounts with such Depositary ("participants"). The accounts to be credited shall be designated by any underwriters, dealers or agents participating in the distribution of such debt securities. Ownership of beneficial interests in a Registered Global Security will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in such Registered Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the 7 Depositary for such Registered Global Security (with respect to interests of participants) or by participants or persons that hold through participants (with respect to interests of persons other than participants). So long as the Depositary for a Registered Global Security, or its nominee, is the registered owner of such Registered Global Security, such Depositary or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by such Registered Global Security for all purposes under the applicable Indenture. Except as set forth below, owners of beneficial interests in a Registered Global Security will not be entitled to have the debt securities represented by such Registered Global Security registered in their names, will not receive or be entitled to receive physical delivery of such debt securities in definitive form and will not be considered the owners or holders thereof under the applicable Indenture. Principal, premium, if any, and interest payments on debt securities represented by a Registered Global Security registered in the name of the Depositary or its nominee will be made to such Depositary or its nominee, as the case may be, as the registered owner of such Registered Global Security. None of the Corporation, the Trustee or any paying agent for such debt securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in such Registered Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The Corporation expects that the Depositary for any debt securities represented by a Registered Global Security, upon receipt of any payment of principal, premium or interest, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Registered Global Security as shown on the records of such Depositary. The Corporation also expects that payments by participants to owners of beneficial interests in such Registered Global Security held through such participants will be governed by standing instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in "street names" and will be the responsibility of such participants. Under the terms of the Indentures, the Corporation and the Trustees will treat the persons in whose names the debt securities are registered as the owners of such debt securities for the purpose of receiving payments of principal, premium, if any, and interest on the debt securities and for all other purposes whatsoever. Therefore, neither the Corporation, the Trustees nor any paying agents has any direct responsibility or liability for the payment of principal, premium, if any, or interest on the debt securities to owners of beneficial interests in a Registered Global Security. If the Depositary for any debt securities represented by a Registered Global Security is at any time unwilling or unable to continue as the Depositary and a successor Depositary is not appointed by the Corporation within 90 days, the Corporation will issue such debt securities in definitive form in exchange for such Registered Global Security. In addition, the Corporation may at any time and in its sole discretion determine not to have any of the debt securities of a series represented by one or more Registered Global Securities and, in such event, will issue debt securities of such series in definitive form in exchange for the Registered Global Security or Registered Global Securities representing such debt securities. In either instance, an owner of a beneficial interest in a Registered Global Security will be entitled to have debt securities equal in principal amount to such beneficial interest registered in its name and will be entitled to physical delivery of such debt securities in definitive form. UNSUBORDINATED DEBT The Unsubordinated Debt Securities that will constitute part of the unsubordinated debt of the Corporation will be issued under the Debt Indenture and will rank PARI PASSU with all other unsecured and unsubordinated debt of the Corporation. SUBORDINATED DEBT The Subordinated Debt Securities that will constitute part of the subordinated debt of the Corporation will be issued under the Subordinated Debt Indenture and will be subordinate and junior in right of payment, to the extent and in the manner set forth in the Subordinated Debt Indenture, to all Senior 8 Indebtedness of the Corporation. The Subordinated Debt Indenture defines "Senior Indebtedness" as obligations (other than non-recourse obligations, the Subordinated Debt Securities or any other obligations specifically designated as being subordinate in right of payment to Senior Indebtedness) of, or guaranteed or assumed by, the Corporation for borrowed money or evidenced by bonds, debentures, notes or other similar instruments, and amendments, renewals, extensions, modifications and refundings of any such indebtedness or obligation, including, but not limited to, obligations of the Corporation under the Mortgage and the Canadian Trust Indenture (as defined below). (Subordinated Debt Indenture, Section 1.1) In the event (a) of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization or other similar proceedings in respect of the Corporation or a substantial part of its property or (b) that (i) a default shall have occurred with respect to the payment of principal of (and premium, if any) or any interest on or other monetary amounts due and payable on any Senior Indebtedness or (ii) there shall have occurred an event of default (other than a default in the payment of principal (or premium, if any) or interest, or other monetary amounts due and payable) with respect to any Senior Indebtedness, as defined therein or in the instrument under which the same is outstanding, permitting the holder or holders thereof to accelerate the maturity thereof (with notice or lapse of time, or both) and such event of default shall have continued beyond the period of grace, if any, in respect thereof, and such default or event of default shall not have been cured or waived or shall not have ceased to exist, or (c) that the principal of and accrued interest on the Subordinated Debt Securities shall have been declared due and payable upon an Event of Default pursuant to Section 5.1 of the Subordinated Debt Indenture and such declaration shall not have been rescinded and annulled as provided therein, then the holders of all Senior Indebtedness shall first be entitled to receive payment of the full amount unpaid thereon, or provisions shall be made for such payment in money or money's worth, before the holders of any of the Subordinated Debt Securities are entitled to receive a payment on account of the principal of (and premium, if any) or any interest on the indebtedness evidenced by such Subordinated Debt Securities. (Subordinated Debt Indenture, Section 13.1). If this prospectus is being delivered in connection with a series of Subordinated Debt Securities, the accompanying Prospectus Supplement or the information incorporated herein by reference will set forth the approximate amount of Senior Indebtedness outstanding as of a recent date. CERTAIN COVENANTS OF THE CORPORATION MERGER, CONSOLIDATION, SALE, LEASE OR CONVEYANCE. Each Indenture provides that the Corporation will not merge, amalgamate or consolidate with any other person and will not sell, lease or convey all or substantially all its assets to any person, unless the Corporation shall be the continuing corporation, or unless the successor corporation or person that acquires all or substantially all the assets of the Corporation shall expressly assume all of the covenants and obligations of the Corporation under the Indenture, and unless immediately after such merger, amalgamation, consolidation, sale, lease or conveyance, the Corporation, such person or such successor corporation shall not be in default in the performance of the covenants and conditions of such Indenture to be performed or observed by the Corporation. (Section 9.1) This covenant would not apply to a recapitalization transaction, a change of control of the Corporation, a transaction with management or management affiliates or a highly leveraged transaction unless such transactions or change of control were structured to include a merger, amalgamation or consolidation or sale, lease or conveyance of all or substantially all of the assets of the Corporation. Except as may be included in a supplemental indenture applicable to a specific series of debt securities and as may be described in a Prospectus Supplement applicable to such debt securities, there are no covenants or other provisions in the Indentures providing for a put or increased interest or otherwise that would afford holders of debt securities additional protection in the event of a recapitalization transaction, a change of control of the Corporation, a transaction with management or management affiliates or a highly leveraged transaction. 9 LIMITATIONS ON LIENS, OWNERSHIP OF SUBSIDIARIES AND CERTAIN OTHER TRANSACTIONS. The Debt Indenture for the Unsubordinated Debt Securities provides that, so long as any Unsubordinated Debt Securities remain outstanding: (1) The Corporation will not, nor will it permit any Designated Subsidiary (as defined below) to, in any way encumber any of its assets to secure any obligations (other than First Mortgage Pipe Line Bonds) unless at the same time all Unsubordinated Debt Securities shall be secured equally and ratably with such obligations; provided that this covenant does not apply to nor operate to prevent, among other things (a) any security given in the ordinary course of business to any bank or banks to secure any Indebtedness (as defined below) payable on demand or maturing (including any right of extension or renewal) within 24 months after the date such Indebtedness is incurred or the date of any renewal or extension thereof, (b) the giving or assumption of security for any Purchase Money Obligation (as defined below), (c) certain permitted liens specified in the Debt Indenture or (d) any liens of a nature similar to the permitted liens specified in the Debt Indenture which do not secure Indebtedness of, or Indebtedness guaranteed by, the Corporation or any Designated Subsidiary and which do not materially impair the use of the property subject thereto or the operation of the business of the Corporation or such Designated Subsidiary or the value of such property for the purpose of such other business; (2) The Corporation will not create, assume or otherwise incur any Funded Obligations (as defined below) ranking prior to the Unsubordinated Debt Securities except additional First Mortgage Pipe Line Bonds; (3) If the Corporation shall cause the payment of the principal of, premium, if any, or interest on any of its Indebtedness to be subordinated to the prior payment of any other of its Indebtedness it shall in like manner subordinate such payment to the prior payment in full of all of the Unsubordinated Debt Securities outstanding under the Debt Indenture; (4) The Corporation will at all times hold Voting Shares (as defined below) of each Designated Subsidiary which, together with Voting Shares of such Designated Subsidiary held by other Designated Subsidiaries, are sufficient to entitle such holders to elect at least a majority of the directors of such Designated Subsidiary; (5) The Corporation will not enter into any agreement providing for the issue or sale of Funded Obligations unless such agreement contains a condition of such issue or sale (which condition can only be waived with the consent of the holders of Unsubordinated Debt Securities expressed by resolution) to the effect that the terms and conditions of the Debt Indenture relating to the creation, assumption or incurring of Funded Obligations shall be complied with at the time of each issue and sale provided for in such agreement; (6) The Corporation will not permit any Designated Subsidiary to issue any shares of its capital stock except (a) to the Corporation, (b) to the extent, if any, required to qualify directors of a Designated Subsidiary under applicable law, (c) pursuant to obligations to issue shares which exist prior to the date when such Designated Subsidiary became a Subsidiary or (d) to the extent issued to other shareholders of such Designated Subsidiary if after giving effect to such issue the pro rata aggregate ownership interest of the Corporation and any other Designated Subsidiaries in the capital stock of such Designated Subsidiary and the Corporation's direct and indirect pro rata voting rights, pro rata interest in shareholders' equity, and pro rata rights to participate in earnings of such Designated Subsidiary are not reduced; and (7) The Corporation will not, and will not permit any Designated Subsidiary to, sell or dispose of any shares of capital stock or Indebtedness of any Designated Subsidiary to any Person other than the Corporation or another Designated Subsidiary unless all shares of capital stock and Indebtedness of such Designated Subsidiary then held by the Corporation and any of its Subsidiaries (together with all shares of capital stock and Indebtedness of the Corporation and other Designated Subsidiaries then held by such Designated Subsidiary) are being sold or disposed of at such time 10 to a Subsidiary of the Corporation for cash at fair value determined by an Independent Appraiser or to persons other than any of the Corporation's Subsidiaries.

Each Indenture provides that no holder of debt securities issued under such Indenture may institute any action against the Corporation under such Indenture (except actions for payment of overdue principal and premium, if any, or interest) unless such holder previously shall have given to the Trustee written notice of default and continuance thereof and unless the holders of not less than 25% in principal amount of the debt securities of each affected series (treated as one class) issued under such Indenture and then outstanding shall have requested the Trustee to institute such action and shall have offered the Trustee reasonable indemnity, the Trustee shall not have instituted such action within 60 days of such request and the Trustee shall not have received direction inconsistent with such written request by the holders of a majority in principal amount of the debt securities of each affected series (treated as one class) issued under such Indenture and then outstanding. (Sections 5.6 and 5.8) Notwithstanding the foregoing, the right of any holder of a debt security to receive payment of the principal of, premium, if any, and interest on such debt security on or after the respective due dates thereof and to institute suit for the enforcement of such payment on or after such respective dates shall not be impaired or affected without the consent of such holder. (Section 5.12) Each Indenture contains a covenant that the Corporation will file annually with the Trustee a certificate with respect to the Corporation's compliance with all covenants and conditions under such Indenture. (Section 3.5) DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE The Corporation can discharge or defease its obligations under each Indenture as set forth below. (Section 10.1) 13 The Corporation may discharge certain obligations to holders of any series of debt securities issued under such Indenture (a) if the Corporation pays the principal of and interest on all the outstanding debt securities of any series as and when the same shall have become due and payable, or (b) if the Corporation delivers to the Trustee for cancellation all debt securities of any series theretofore authenticated, or (c) in the case of any series of debt securities where the exact amount of principal of and interest due on which can be determined at the time of making the deposit referred to in clause (ii) below, if (i) all the debt securities of such series not theretofore delivered to the Trustee for cancellation have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements reasonably satisfactory to the Trustee, and (ii) the Corporation irrevocably deposits with the Trustee as trust funds cash (in such Currency in which such debt securities are payable at their stated maturity) (other than moneys repaid by the Trustee or any paying agent to the Corporation), or Government Obligations (as defined in such Indenture) applicable to such debt securities (determined on the basis of the Currency in which such debt securities are then specified as payable at their stated maturity), maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or a combination thereof in an amount certified by a nationally recognized firm of independent public or chartered accountants to be sufficient to pay at maturity (or upon redemption or pursuant to mandatory sinking fund payments) the principal of, premium, if any, and interest on all outstanding debt securities of such series; and if, in any such case, the Corporation pays all other sums payable under the Indenture by the Corporation. The Corporation may also discharge any and all of its obligations to holders of any series of debt securities issued under an Indenture at any time ("defeasance") upon compliance with conditions discussed below if the exact amounts of principal and interest due on such debt securities can be determined, with the exception of its duty to register the transfer or exchange of such series of debt securities, to replace any mutilated, destroyed, lost or stolen series of debt securities or to maintain an office or agency in respect of such series of debt securities. Under terms reasonably satisfactory to the relevant Trustee, the Corporation may instead be released with respect to any outstanding series of debt securities issued under the relevant Indenture from the obligations imposed by Sections 3.6 and 9.1, in the case of the Debt Indenture, and Section 9.1, in the case of the Subordinated Debt Indenture (which Sections contain the covenants described above under "Certain Covenants of the Corporation"), and omit to comply with such Sections without creating an Event of Default ("covenant defeasance"). Defeasance or covenant defeasance may be effected only if, among other things: (i) the Corporation irrevocably deposits with the Trustee, as trust funds specifically pledged as security for, and dedicated solely to, the benefit of the holders of such debt securities, cash (in such Currency, in which such debt securities are specified as payable at their stated maturity) or Government Obligations applicable to such debt securities (determined on the basis of the Currency in which such debt securities are then specified as payable at their stated maturity), maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or a combination thereof in an amount certified by a nationally recognized firm of independent public or chartered accountants to be sufficient to pay at maturity (or upon redemption or pursuant to mandatory sinking fund payments) the principal of, premium, if any, and interest on all outstanding debt securities of such series issued under such Indenture; (ii) such deposit will not result in breach or violation of, or constitute a default under, any agreement or instrument to which the Corporation is a party or by which it is bound; (iii) the Corporation delivers to the relevant Trustee an opinion of counsel to the effect that the holders of such series of debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of such defeasance or covenant defeasance and that defeasance or covenant defeasance will not otherwise alter such holders' United States federal income tax treatment of principal, premium, if any, and interest payments on such series of debt securities (in the case of a defeasance, such opinion must be based on a ruling of the Internal Revenue Service or a change in the United States federal income tax law occurring after the date of such Indenture, since such a result would not occur under current tax law); (iv) the Corporation delivers to the relevant Trustee an opinion of Canadian counsel to the effect that such deposit and related defeasance or covenant defeasance, as the case may be, will not cause the holders of such series of debt securities, other than holders of such series of debt securities who are or who are deemed to be residents of Canada or use or hold or are deemed to use or hold their debt securities of such series in carrying on a business in Canada, to recognize income, 14 gain or loss for Canadian income tax purposes, and to the effect that payments out of the trust fund described above will be free and exempt from any and all withholding and other income taxes of whatever nature of Canada or any province thereof or political subdivision thereof or therein having power to tax, except in the case of debt securities of such series beneficially owned (a) by a person who is or is deemed to be a resident of Canada or (b) by a person who uses or holds or is deemed to use or hold such series of debt securities in carrying on a business in Canada; and (v) in the case of the Subordinated Debt Indenture (a) no event or condition shall exist that, pursuant to certain provisions described under "Subordinated Debt" above, would prevent the Corporation from making payments of principal of, and premium, if any, and interest on the Subordinated Debt Securities at the date of the irrevocable deposit referred to above and (b) the Corporation delivers to the Trustee for the Subordinated Debt Indenture an opinion of counsel to the effect that (1) the trust funds will not be subject to any rights of holders of Senior Indebtedness and (2) the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; provided however, that such opinion may contain an exception to the effect that if a court were to rule under any such law in any case or proceeding that the trust funds remained property of the Corporation, then the Trustee and the holders of the Subordinated Debt Securities would be entitled to certain rights as secured creditors in such trust funds. MODIFICATION OF THE INDENTURES Each Indenture provides that the Corporation and the Trustee may enter into supplemental indentures without the consent of the holders of debt securities to: (a) secure any debt securities, (b) evidence the succession of another corporation to the Corporation, or successive successions, and the assumption by the successor corporation of the obligations of the Corporation, (c) add covenants for the benefit of the holders of debt securities, (d) cure any ambiguity or correct any inconsistency in such Indenture, (e) establish the form or terms of debt securities of any series, (f) evidence the acceptance of appointment by a successor trustee under the Indenture with respect to one or more series of debt securities and provide for or facilitate the administration of one or more trusts under the Indenture by one or more trustees, and (g) provide for or facilitate the issuance of debt securities in bearer form or provide for uncertificated securities. (Section 8.1) Each Indenture also contains provisions permitting the Corporation and the Trustee, with the consent of the holders of not less than a majority in principal amount of debt securities of each series issued under such Indenture then outstanding and affected, to add any provisions to, or change in any manner or eliminate any of the provisions of, such Indenture or modify in any manner the rights of the holders of the debt securities of each series so affected; provided that the Corporation and the Trustee may not, without the consent of the holder of each outstanding debt security affected thereby, (a) extend the stated maturity of the principal of any debt security, or reduce the principal amount thereof or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof, or change the place at which or currency in which principal and interest payments are to be made, or reduce the amount of any original issue discount security payable upon acceleration or provable in bankruptcy or impair the right to institute suit for the enforcement of any payment on any debt security when due or (b) reduce the aforesaid percentage in principal amount of debt securities of any series issued under such Indenture, the consent of the holders of which is required for any such modification. (Section 8.2) The Subordinated Debt Indenture may not be amended to alter the subordination of any outstanding Subordinated Debt Securities without the consent of each holder of Senior Indebtedness then outstanding that would be adversely affected thereby. (Subordinated Debt Indenture, Section 8.6) CONSENT TO JURISDICTION Each Indenture provides that the Corporation agrees that any legal suit, action or proceeding brought by the applicable Trustee or any holder of debt securities issued under such Indenture in connection with such debt securities or such Indenture may be instituted in any State or Federal court in The City of New York. (Section 11.12) 15 CONCERNING THE TRUSTEE The Bank of Nova Scotia, the parent of The Bank of Nova Scotia Trust Company of New York, is one of a number of financial institutions with which the Corporation and its subsidiaries maintain ordinary banking relationships and with which the Corporation and its subsidiaries maintain credit facilities. GOVERNING LAW The Indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York. ENFORCEABILITY OF CIVIL LIABILITIES The Corporation is a Canadian corporation, and the majority of its assets and operations are located, and the majority of its revenues are derived, outside the United States. In addition, certain of the directors and officers of the Corporation are residents of Canada or other jurisdictions outside of the United States, and all or a substantial portion of the assets of those directors and officers are or may be located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon those persons, or to enforce against them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of United States federal and state securities laws. CERTAIN INCOME TAX CONSIDERATIONS The applicable Prospectus Supplement will describe certain Canadian federal income tax consequences to an investor who is a non-resident of Canada acquiring any debt securities offered thereunder, including whether payments of principal, premium, if any, and interest on debt securities will be subject to Canadian non-resident withholding tax. The applicable Prospectus Supplement will also describe certain United States federal income tax consequences of the purchase, ownership and disposition of any debt securities offered thereunder by an investor who is a United States person (within the meaning of the United States Internal Revenue Code), including, to the extent applicable, any such consequences relating to debt securities payable in a currency other than the United States dollar, issued at an original issue discount for United States federal income tax purposes or containing early redemption provisions or other special items. PLAN OF DISTRIBUTION The Corporation may offer and sell the debt securities to or through underwriters or dealers purchasing as principals, and also may sell the debt securities to one or more purchasers directly or through agents. The distribution of the debt securities may be effected from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a non-fixed price basis, the debt securities may be offered at market prices prevailing at the time of sale or at prices related to such prevailing market prices or at prices to be negotiated with purchasers, in which case the compensation payable to any underwriter, dealer or agent in connection with any such sale will be the amount, if any, by which the aggregate price paid for the debt securities by the purchasers exceeds the gross proceeds paid by the underwriter, dealer or agent to the Corporation and the price at which the debt securities will be offered and sold may vary as between purchasers during the distribution period. The Prospectus Supplement relating to each offering of debt securities will identify each underwriter, dealer or agent, as the case may be, and will also set forth the terms of the offering, including the type of security being offered, the public offering price (or the manner of determination thereof if offered on a non-fixed price basis), the proceeds to the Corporation and any underwriting fees or commissions, any fees or commissions to be paid to any agents and any fees, commissions or concessions allowed or reallowed or paid by any underwriters to other dealers. 16 The Prospectus Supplement will also set forth the intention of any underwriters, agents or dealers to engage in stabilizing, syndicate short covering transactions, penalty bids, or any other transactions during the offering that may stabilize, maintain, or otherwise affect the debt security's price. Under agreements which may be entered into by the Corporation, underwriters, dealers and agents who participate in the distribution of the debt securities may be entitled to indemnification by the Corporation against certain liabilities, including liabilities under the Securities Act. The debt securities may be offered and sold by the Corporation directly or through agents designated by the Corporation from time to time. Any agent participating in the distribution of the debt securities may be deemed to be an "underwriter", as that term is defined in the Securities Act, of the debt securities so offered and sold. The debt securities also may be sold to dealers at the applicable price to the public set forth in the applicable Prospectus Supplement for resale to purchasers. Such dealers may be deemed to be "underwriters" within the meaning of the Securities Act. The debt securities will not be qualified for sale under the securities laws of Canada or any province or territory of Canada. Each underwriter, dealer or agent participating in a distribution of the debt securities must agree that it will not offer or sell, directly or indirectly, any of the debt securities acquired by it in connection with a distribution in Canada or to residents of Canada in contravention of the securities laws of Canada or any applicable province or territory thereof. Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of the debt securities will be a new issue of securities with no established trading market and will not be listed on any securities or stock exchange. In connection with any offering of the debt securities, the underwriters or agents may, subject to the foregoing, over-allot or effect transactions which stabilize or maintain the market price of the debt securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. Any underwriters or agents to or through whom the debt securities are sold by the Corporation for public offering and sale may make a market in the debt securities, but such underwriters or agents will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that a trading market in any of the debt securities will develop or as to the liquidity of any trading market for such debt securities. If so indicated in the Prospectus Supplement relating to a particular offering of debt securities, the Corporation will authorize underwriters, dealers or agents to solicit offers by certain institutions to purchase such debt securities from the Corporation pursuant to delayed delivery contracts providing for payment and delivery at a future date. Such contracts will be subject only to those conditions set forth in the Prospectus Supplement, and the Prospectus Supplement will set forth the commission payable for solicitations of such contracts. RISK FACTORS Investment in the debt securities is subject to various risks including those risks inherent to the pipeline and power industry sectors. Before deciding whether to invest in any debt securities, investors should consider carefully the risks incorporated by reference in this prospectus (including subsequently filed documents incorporated by reference) and those described in a Prospectus Supplement relating to a specific offering of debt securities. Discussions of certain risk factors affecting the Corporation in connection with its business are provided in the Corporation's annual disclosure documents filed with the various securities regulatory authorities, which are incorporated by reference in this prospectus. 17 LEGAL MATTERS Certain matters will be passed upon for the Corporation by McCarthy Tetrault LLP, Calgary, Alberta and by Mayer, Brown, Rowe & Maw, Chicago, Illinois.
