PART I

INFORMATION REQUIRED TO BE

DELIVERED TO OFFEREES OR PURCHASERS

No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise.

This short form prospectus has been filed under legislation in each of the provinces and territories of Canada that permits certain information about these securities to be determined after this prospectus has become final and that permits the omission from this prospectus of that information. The legislation requires the delivery to purchasers of a prospectus supplement containing the omitted information within a specified period of time after agreeing to purchase any of these securities (except where an exemption from such delivery requirement is available). This short form base shelf prospectus has been filed in reliance on an exemption from the preliminary base shelf prospectus requirement for a well-known seasoned issuer.

This prospectus constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such securities.

Information has been incorporated by reference in this prospectus from documents filed with securities commissions or similar authorities in Canada. Copies of the documents incorporated herein by reference may be obtained on request without charge from the Corporate Secretary of TransCanada PipeLines Limited at 450 – 1^st Street S.W. Calgary, Alberta, Canada T2P 5H1 (telephone (403) 920-2000), and are also available electronically at www.sedarplus.ca.

Information contained herein is subject to completion or amendment. A registration statement relating to these securities has been filed with the United States Securities and Exchange Commission. This prospectus shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

SHORT FORM BASE SHELF PROSPECTUS

New Issue December 5, 2024

TRANSCANADA PIPELINES LIMITED

Debt Securities

TransCanada PipeLines Limited (“TCPL” or the “Corporation”) may from time to time offer and issue unsecured bonds, debentures, notes or other evidences of indebtedness of any kind, nature or description (the “debt securities”) during the 25-month period that this short form base shelf prospectus, including any amendments hereto (the “prospectus”), remains valid, as shall be designated by the Corporation at the time of offering.

The specific terms of any offering of debt securities will be set forth in one or more shelf prospectus supplements (each, 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 generally, or to any particular debt securities, that are not prohibited by the parameters set forth in this prospectus.

All shelf information permitted under applicable laws to be omitted from this prospectus will be contained in one or more prospectus supplements that will be delivered to purchasers together with this prospectus, except where an exemption from such delivery requirement is available. Each prospectus supplement will be incorporated by reference into this prospectus for the purposes of securities legislation as of the date of such prospectus supplement and only for the purposes of the distribution of the debt securities to which such prospectus supplement pertains.

TCPL may offer and 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 TCPL in connection with the offering and sale of the debt securities, and will also set forth the terms of the offering of such debt securities, including the method of distribution of such debt securities, the proceeds to TCPL and any fees, discounts or other compensation payable to the underwriters, dealers or agents and any other material terms of the plan of distribution. No underwriter, dealer or agent has been involved in the preparation of this prospectus or performed any review of the contents of this prospectus.

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 and will not be listed on any securities or stock exchange. 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 or at prices to be negotiated with purchasers at the time of sale, which prices may vary as between purchasers and during the period of distribution. If debt securities are offered on a non-fixed price basis, the underwriters’, dealers’ or agents’ compensation will be increased or decreased by the amount by which the aggregate price paid for the debt securities by the purchasers exceeds or is less than the gross proceeds paid by the underwriters, dealers’ or agents’ to TCPL. See “Plan of Distribution”.

In connection with any offering of debt securities, the underwriters, dealers or agents may 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. See “Plan of Distribution.”

TCPL’s head office and registered office is located at 450 - 1st Street S.W., Calgary, Alberta, Canada, T2P 5H1.

There is no market through which the debt securities may be sold and purchasers may not be able to resell debt securities purchased under this prospectus. This may affect the pricing of the debt securities in the secondary market, the transparency and availability of trading prices, the liquidity of the debt securities, and the extent of issuer regulation. See “Risk Factors” as well as the “Risk Factors” section of the applicable prospectus supplement.

We are permitted, as a Canadian issuer, under a multijurisdictional disclosure system adopted by the United States (“U.S.”), to prepare this prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the U.S.

You should be aware that the acquisition of the debt securities described herein may have tax consequences both in the U.S. and in Canada. Such tax consequences for investors who are residents in, or citizens of, the U.S. may not be described fully herein or in any applicable prospectus supplement. You should read the tax discussion in any applicable prospectus supplement, however, this prospectus or any applicable prospectus supplement may not fully describe these tax consequences.

Your ability to enforce civil liabilities under U.S. federal securities laws may be affected adversely by the fact that we are incorporated under the laws of Canada, that some or all of our officers and directors may be residents of Canada, that some or all of the experts named in the registration statement may be residents of Canada and that all or a substantial portion of our assets and the assets of said persons are located outside the U.S.

As of the date hereof, the Corporation has determined that it qualifies as a “well-known seasoned issuer” under the WKSI Blanket Orders (as defined herein). See “Reliance on Exemptions for Well-Known Seasoned Issuers”.

Scott B. Bonham, Cheryl F. Campbell, Bill Johnson, John E. Lowe, Mary Pat Salomone, Thierry Vandal and Dheeraj Verma are directors of the Corporation who reside outside of Canada and each of these directors has appointed the Corporation as agent for service of process at 450 - 1st Street, S.W., Calgary, Alberta, Canada T2P 5H1. Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person who resides outside of Canada, even if the party has appointed an agent for service of process.

THESE DEBT SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE U.S. SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) OR ANY STATE SECURITIES COMMISSION NOR HAS THE SEC OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Any statement so modified or superseded shall not constitute a part of this prospectus, except as so modified or superseded.

WHERE TO FIND MORE INFORMATION

We have filed with the SEC, under the Securities Act, a registration statement on Form F-10 relating to the debt securities. This prospectus, which constitutes a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. Statements included or incorporated by reference in this prospectus about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, you should refer to the exhibits for a complete description of the matter involved. Under the registration statement, we may, from time to time, sell any combination of the debt securities described in this prospectus in one or more offerings. Each time we sell debt securities under the registration statement, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus.

Subject to the exemptive relief in the Decision, we file annual and quarterly financial information and material change reports, business acquisition reports and other material with the securities commission or other similar authority in each of the provinces and territories of Canada and with the SEC. Under the multijurisdictional disclosure system adopted by the U.S., documents and other information that we file with the SEC may be prepared in accordance with the disclosure requirements of Canada, which are different from those of the U.S. You may read and download any public document that the Corporation has filed with the securities commission or other similar authority in each of the provinces and territories of Canada on SEDAR+ at www.sedarplus.ca.

THE CORPORATION

TCPL operates in two core businesses - Natural Gas Pipelines and Power and Energy Solutions. In order to provide information that is aligned with how management decisions about our businesses are made and how performance of our businesses is assessed, our results are reflected in four operating segments: Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, Mexico Natural Gas Pipelines and Power and Energy Solutions. We also have a Corporate segment consisting of corporate and administrative functions that provide governance, financing and other support to our business segments.

CONSOLIDATED CAPITALIZATION

Pursuant to the Decision, the Corporation is exempt from filing its own annual and interim financial statements and incorporates TCE’s annual and interim financial statements into this prospectus.

On August 28, 2024, in connection with the spinoff Transaction, South Bow Canadian Infrastructure Holdings Ltd. and 6297782 LLC (together, the “South Bow Debt Issuers”) completed an offering of approximately $7.9 billion Canadian-dollar equivalent of senior unsecured notes and junior subordinated notes (collectively, the “South Bow Notes”), of which approximately $6.2 billion was placed in escrow pending the completion of the spinoff Transaction (the “Escrowed Funds”).

DESCRIPTION OF DEBT SECURITIES

As used in this section, the term “Corporation” means TransCanada PipeLines Limited, and does not include the subsidiaries of TransCanada PipeLines Limited through which particular business operations are conducted. The following description sets forth the general terms and provisions of the debt securities, with the exception of certain terms and provisions which may be omitted from this prospectus pursuant to NI 44-102. The Corporation will provide the particular terms and provisions of a series of debt securities and a description of how the general terms and provisions described below may apply to that series in the applicable prospectus supplement.

Pursuant to this prospectus, the Corporation may offer debt securities that will rank pari passu, except as to sinking funds and claims preferred by operation of law, with all other unsecured and unsubordinated debt of the Corporation (“Unsubordinated Debt Securities”) as well as 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”). Unsubordinated Debt Securities may be issued under: (i) the second amended and restated debt indenture, dated September 15, 2010, as supplemented or amended from time to time (the “U.S. Unsubordinated Debt Indenture”), between the Corporation and The Bank of New York Mellon (formerly known as The Bank of New York), as trustee; or (ii) the trust indenture, dated December 15, 2004, as supplemented or amended from time to time (the “Canadian Unsubordinated Debt Indenture”), between the Corporation and BNY Trust Company of Canada, as successor trustee. Subordinated Debt Securities may be issued under the amended and restated subordinated debt indenture, dated November 30, 2000, as supplemented or amended from time to time (the “U.S. Subordinated Debt Indenture” and, together with the U.S. Unsubordinated Debt Indenture, the “U.S. Indentures”), between the Corporation and Computershare Trust Company, N.A., as successor trustee. The U.S. Indentures and the Canadian Unsubordinated Debt Indenture are collectively referred to herein as the “Indentures”. The Corporation may also, from time to time, issue debt securities and incur additional indebtedness pursuant to this prospectus under one or more indentures other than the Indentures as may be described in the applicable prospectus supplement.

General

None of the Indentures limit 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 under the Indentures or otherwise. The Corporation may, from time to time, issue debt instruments and incur additional indebtedness other than through the issuance of debt securities pursuant to this prospectus.

The Indentures provide that debt securities may be created and issued from time to time in one or more series and may be denominated and payable in Canadian dollars, U.S. dollars or any other currency. Special Canadian and U.S. federal income tax considerations applicable to any of the debt securities denominated in a currency other than Canadian dollars or U.S. dollars will be described in the applicable prospectus supplement.

8

The debt securities will be unsecured obligations. The Indentures also permit the Corporation to increase the principal amount of any series of the debt securities previously issued and to issue that increased principal amount. Reference must be made to the prospectus supplement for specific terms of and information relating to the debt securities offered thereunder (to the extent such terms are applicable to such debt securities) including the following:

(1) classification as Unsubordinated Debt Securities or Subordinated Debt Securities, the specific designation, aggregate principal amount, purchase price and denominations;

(2) any date of maturity;

(3) interest rate or rates (whether fixed or variable) at which the debt securities will bear interest, if any, or the method by which such rate or rates will be determined and the date or dates from which such interest will accrue;

(4) the date or dates, or the method by which such date or dates will be determined or extended, on which principal of and premium and interest on the debt securities will be payable, if any;

(5) any redemption, repayment or sinking fund provisions;

(6) if applicable, the portion of the principal amount of the debt securities, if other than the principal amount thereof, payable upon acceleration of the maturity thereof;

(7) the currency in which payment of the principal of or interest, if any, on the debt securities shall be payable or in which the debt securities shall be denominated and the particular provisions applicable thereto;

(8) any index, formula or other method used to determine the amount of payments of principal of and premium and interest, if any, on the debt securities;

(9) if the debt securities may be issued bearing no interest or at a discount below their stated principal amount;

(10) whether the debt securities will be issuable in the form of one or more global debt securities and, if so, the identity of the depository for the global debt securities;

(11) whether and under what circumstances the debt securities will be convertible into or exchangeable for other securities of the Corporation or securities of other entities;

(12) whether the principal of and premium and interest, if any, on the debt securities are to be payable in a currency other than that in which such debt securities are denominated or stated to be payable, and other information, including the method of calculating the applicable exchange rate, related thereto; and

(13) any other specific terms, conditions, rights and preferences (or limitations on such rights or preferences) of the 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.

Debt securities will bear interest at a fixed rate or a floating rate. 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. If and to the extent applicable, the Canadian and U.S. federal income tax consequences and other special 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 Canadian and/or U.S. federal income tax purposes will be described in the relevant prospectus supplement.

U.S. Indentures

The following summary of certain provisions of the U.S. Indentures does not purport to be complete and such summary is subject to, and qualified in its entirety by, the detailed provisions of the applicable U.S.

9

Indenture to which reference is hereby made, including the definitions of certain terms used herein. For a more complete description, you should consult the U.S. Indentures. The U.S. Indentures have been filed as exhibits to the registration statement. Copies of the U.S. Indentures have also been filed on SEDAR+. The U.S. Indentures are substantially identical, except for the provisions relating to subordination and certain covenants. See “Subordinated Debt” and “Certain Covenants of the Corporation”. As used in this section, Bank of New York Mellon (formerly known as The Bank of New York) and Computershare Trust Company, N.A. are referred to individually as a “U.S. Trustee” and collectively as the “U.S. Trustees”. The U.S. Indentures provide that all accounting terms not specifically defined therein are to be construed in accordance with accounting principles as are generally accepted in Canada (“GAAP”) at the time of computation and may include international financial reporting standards or U.S. generally accepted accounting principles.

Unsubordinated Debt

The Corporation may issue Unsubordinated Debt Securities under the U.S. Unsubordinated Debt Indenture. Any Unsubordinated Debt Securities will rank pari passu with all other unsecured and unsubordinated debt of the Corporation except as to sinking funds and claims preferred by operation of law.

Subordinated Debt

The Corporation may issue Subordinated Debt Securities under the U.S. Subordinated Debt Indenture. Any Subordinated Debt Securities issued under the U.S. Subordinated Debt Indenture will be subordinate and junior in right of payment, to the extent and in the manner set forth in the U.S. Subordinated Debt Indenture, to all Senior Indebtedness of the Corporation.

The U.S. 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 Canadian Trust Indenture (as defined below).

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 issued under the U.S. Subordinated Debt Indenture shall have been declared due and payable upon an Event of Default pursuant to the U.S. Subordinated Debt Indenture and such declaration shall not have been rescinded and annulled as provided therein, then in any such case 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 issued under the U.S. Subordinated Debt Indenture 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. In connection with any offering of Subordinated Debt Securities pursuant to this prospectus, the applicable 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 U.S. 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 to be performed and conditions to be observed by the Corporation under the applicable U.S. 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 U.S. Indenture to be performed or observed by the Corporation.

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 U.S. 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.

Limitations on Liens, Ownership of Subsidiaries and Certain Other Transactions. The U.S. Unsubordinated Debt Indenture provides that, so long as any Unsubordinated Debt Securities issued under the U.S. Unsubordinated Debt Indenture remain outstanding:

(1) the Corporation will not, nor will it permit any Designated Subsidiary (as defined below) to, mortgage, hypothecate, charge, pledge or otherwise encumber any of its assets to secure any obligations unless at the same time all Unsubordinated Debt Securities issued under the U.S. Unsubordinated Debt Indenture 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 U.S. Unsubordinated Debt Indenture or (d) any liens of a nature similar to the permitted liens specified in the U.S. Unsubordinated 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 issued under the U.S. Unsubordinated Debt Indenture;

(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 U.S. Unsubordinated 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

11

with the consent of the holders of Unsubordinated Debt Securities issued under the U.S. Unsubordinated Debt Indenture expressed by resolution) to the effect that the terms and conditions of the U.S. Unsubordinated 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 to a Subsidiary of the Corporation for cash at fair value determined by an Independent Appraiser (as defined below) or to persons other than any of the Corporation’s Subsidiaries.

Events of Default

An Event of Default is defined under each U.S. Indenture with respect to debt securities of any series issued under such U.S. Indenture as being:

(1) a default in payment of any principal of, and premium, if any, on the debt securities of such series, either at maturity (or upon any redemption), by declaration or otherwise;

(2) a default for 30 days in payment of any interest on any debt securities of such series;

(3) a default for 60 days after written notice in the observance or performance of any other covenant or agreement in the debt securities of such series or such U.S. Indenture other than a covenant included in such U.S. Indenture solely for the benefit of a series of debt securities other than such series;

(4) certain events of bankruptcy, insolvency or reorganization;

(5) failure by the Corporation to make any payment at maturity, including any applicable grace period, in respect of any issue of Indebtedness in an aggregate amount in excess of US$50,000,000 and continuance of such failure for a period of 30 days after written notice thereof to the Corporation by the applicable U.S. Trustee, or to the Corporation and the applicable U.S. Trustee by the holders of not less than 25% in principal amount of the outstanding debt securities (treated as one class) issued under such U.S. Indenture;

(6) a default with respect to any Indebtedness, which default results in the acceleration of any issue of Indebtedness in an aggregate amount in excess of US$50,000,000 without such Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled for a period of 30 days after written notice thereof to the Corporation by the applicable U.S. Trustee, or to the Corporation and the applicable U.S. Trustee by the holders of not less than 25% in principal amount of the outstanding debt securities (treated as one class) issued under such U.S. Indenture; or

(7) any event of default provided with respect to that series,

12

provided that if any such failure, default or acceleration referred to in clause (5) or (6) above shall cease or be cured, waived, rescinded or annulled, then the Event of Default by reason thereof shall be deemed likewise to have been thereupon cured.

Each U.S. Indenture provides that: (a) if an Event of Default due to the default in payment of principal of, premium, if any, or interest on any series of debt securities issued under such U.S. Indenture or due to the default in the performance or breach of any other covenant or warranty of the Corporation applicable to the debt securities of such series but not applicable to all outstanding debt securities issued under such U.S. Indenture shall have occurred and be continuing, either the applicable U.S. Trustee or 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 U.S. Indenture and then outstanding may then declare the principal of all debt securities of each such affected series and interest accrued thereon to be due and payable immediately; and (b) if an Event of Default due to a default in the performance of any of the other covenants or agreements in such U.S. Indenture applicable to all outstanding debt securities issued thereunder and then outstanding, due to the failure to make any payment at maturity on certain other Indebtedness, due to a default on certain other Indebtedness which has caused an acceleration of such Indebtedness or due to certain events of bankruptcy, insolvency and reorganization of the Corporation shall have occurred and be continuing, unless the principal of all the debt securities issued thereunder has already become due and payable, either the applicable U.S. Trustee or the holders of not less than 25% in principal amount of all debt securities issued under such U.S. Indenture and then outstanding (treated as one class) may declare the principal of, and premium, if any, on all such debt securities and interest accrued thereon to be due and payable immediately, but upon certain conditions such declarations may be annulled and past defaults may be waived (except a continuing default in payment of principal of (or premium, if any) or interest on such debt securities) by the holders of a majority in principal amount of the debt securities of all such affected series then outstanding.

Each U.S. Indenture contains a provision entitling the applicable U.S. Trustee, subject to the duty of such U.S. Trustee during a default to act with the required standard of care, to be indemnified by the holders of debt securities (treated as one class) issued under such U.S. Indenture before proceeding to exercise any right or power under such U.S. Indenture at the request of such holders. Subject to such provisions in each U.S. Indenture for the indemnification of the applicable U.S. Trustee and certain other limitations, the holders of a majority in principal amount of the outstanding debt securities (treated as one class) issued under such U.S. Indenture may direct the time, method and place of conducting any proceeding for any remedy available to the applicable U.S. Trustee, or exercising any trust or power conferred on such U.S. Trustee.

Under the U.S. Trust Indenture Act of 1939, each U.S. Trustee is required to give to the holders of debt securities issued under the applicable U.S. Indenture, within 90 days after the occurrence of a default thereunder, notice of all defaults known to such U.S. Trustee. Except in the case of a default in the payment of principal of (or premium, if any) or interest on any debt securities issued under a U.S. Indenture, the applicable U.S. Trustee shall be protected in the withholding of such notice if it determines in good faith that the withholding of such notice is in the interest of the holders of the debt securities issued under such U.S. Indenture.

Each U.S. Indenture provides that no holder of debt securities issued under such U.S. Indenture may institute any action against the Corporation under such U.S. Indenture (except actions for payment of overdue principal and premium, if any, or interest) unless such holder previously shall have given to the applicable U.S. 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 U.S. Indenture and then outstanding shall have requested the applicable U.S. Trustee to institute such action and shall have offered such U.S. Trustee such indemnity as it may reasonably require, such U.S. Trustee shall not have instituted such action within 60 days of such request and such U.S. 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 U.S. Indenture and then outstanding.

13

Notwithstanding the foregoing, the right of any holder of a debt security issued under a U.S. Indenture to receive payment of the principal of 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.

Each U.S. Indenture contains a covenant that the Corporation will file annually with the applicable U.S. Trustee a certificate with respect to the Corporation’s compliance with all covenants and conditions under such U.S. Indenture.

Discharge, Defeasance and Covenant Defeasance

The Corporation can discharge or defease its obligations under each U.S. Indenture as set forth below.

The Corporation may discharge certain obligations to holders of any series of debt securities issued under a U.S. Indenture (a) if the Corporation pays the principal of and interest on all the outstanding debt securities of any series issued under such U.S. Indenture as and when the same shall have become due and payable, or (b) if the Corporation delivers to the applicable U.S. Trustee for cancellation all debt securities of any series issued under such U.S. Indenture theretofore authenticated, or (c) in the case of any series of debt securities issued under such U.S. Indenture 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 applicable U.S. 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 such U.S. Trustee, and (ii) the Corporation irrevocably deposits with the applicable U.S. Trustee as trust funds cash (in such currency in which such debt securities are payable at their stated maturity) (other than moneys repaid by such U.S. Trustee or any paying agent to the Corporation), or Government Obligations (as defined in such U.S. 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 such U.S. 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 a U.S. 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 U.S. Trustee, the Corporation may instead be released with respect to any outstanding series of debt securities issued under the relevant U.S. Indenture from the obligations imposed by certain provisions of such U.S. Indenture, including the covenants described above under “Certain Covenants of the Corporation”, and omit to comply with such provisions without creating an Event of Default (“covenant defeasance”). Defeasance or covenant defeasance may be effected only if, among other things:

(1) the Corporation irrevocably deposits with the applicable U.S. 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

14

sinking fund payments) the principal of, premium, if any, and interest on all outstanding debt securities of such series issued under such U.S. Indenture;

(2) 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;

(3) the Corporation delivers to the relevant U.S. 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 U.S. 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’ U.S. 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 U.S. federal income tax law occurring after the date of such U.S. Indenture, since such a result would not occur under current tax law);

(4) the Corporation delivers to the relevant U.S. 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, 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

(5) in the case of the U.S. 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 issued under the U.S. Subordinated Debt Indenture at the date of the irrevocable deposit referred to above and (b) the Corporation delivers to the applicable U.S. Trustee an opinion of counsel to the effect that (i) the trust funds will not be subject to any rights of holders of Senior Indebtedness and (ii) 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 applicable U.S. Trustee and the holders of the Subordinated Debt Securities issued under the U.S. Subordinated Debt Indenture would be entitled to certain rights as secured creditors in such trust funds.

Modification and Waiver

Each U.S. Indenture provides that the Corporation and the applicable U.S. Trustee may enter into supplemental indentures without the consent of the holders of debt securities issued thereunder to: (a) secure any debt securities issued thereunder; (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 thereunder; (c) add covenants for the benefit of the holders of debt securities issued thereunder; (d) cure any ambiguity or correct any inconsistency therein; (e) establish the form or terms of debt securities of any series issuable thereunder; (f) evidence the acceptance of appointment by a successor trustee under such U.S. Indenture with respect to one or more series of debt securities issued thereunder and provide for or facilitate the administration of one or more trusts under such U.S. Indenture by one or more trustees; and (g) provide for or facilitate the issuance of debt securities thereunder in bearer form or provide for uncertificated securities.

Each U.S. Indenture also contains provisions permitting the Corporation and the applicable U.S. Trustee, with the consent of the holders of not less than a majority in principal amount of debt securities of each series

15

issued under such U.S. Indenture then outstanding and affected, to add any provisions to, or change in any manner or eliminate any of the provisions of, such U.S. 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 applicable U.S. Trustee may not, without the consent of the holder of each outstanding debt security issued under a U.S. Indenture affected thereby, (a) extend the stated maturity of the principal of any such 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 such debt security when due or (b) reduce the aforesaid percentage in principal amount of debt securities of any series issued under such U.S. Indenture, the consent of the holders of which is required for any such modification.

The holders of a majority in principal amount of the outstanding debt securities of any series issued under a U.S. Indenture may on behalf of the holders of all debt securities of that series waive, insofar as that series is concerned, compliance by the Corporation with certain restrictive provisions of the applicable U.S. Indenture. The holders of a majority in principal amount of outstanding debt securities of any series issued under a U.S. Indenture may waive any past default under such U.S. Indenture with respect to that series, except in respect of a provision which under such U.S. Indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of that series (including a default in the payment of the principal of (or premium, if any) and interest, if any, on any debt security of that series).

The U.S. 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.

Consent to Jurisdiction and Service

Each U.S. Indenture provides that the Corporation agrees that any legal suit, action or proceeding brought by the applicable U.S. Trustee or any holder of debt securities issued under such U.S. Indenture in connection with such debt securities or such U.S. Indenture may be instituted in any State or Federal court in The City of New York and the Corporation has appointed CT Corporation System at 111 Eighth Avenue, 13th Floor., New York, NY 10011 as its authorized agent for service of process in any such suit, action or proceeding.

Governing Law

The U.S. Indentures are and the debt securities issued thereunder will be governed by and construed in accordance with the laws of the State of New York.

Global Securities

Unless otherwise indicated in an applicable prospectus supplement, the debt securities of a series issued under a U.S. Indenture may be issued in the form of one or more fully registered global debt securities (“U.S. Registered Global Security”) that will be deposited with The Depository Trust Company (“DTC”) or with a nominee for DTC identified in the prospectus supplement relating to such series. In such case, one or more U.S. 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 U.S. Registered Global Security or U.S. Registered Global Securities. Unless and until it is exchanged for debt securities in definitive registered form, a U.S. Registered Global Security may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of such successor.

The specific terms of DTC’s arrangement with respect to any portion of a series of debt securities to be represented by a U.S. 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 such arrangements.

16

Upon the issuance of a U.S. Registered Global Security, DTC will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by such U.S. Registered Global Security to the accounts of persons that have accounts with DTC (“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 U.S. Registered Global Security will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in such U.S. Registered Global Security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC (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 DTC, or its nominee, is the registered owner of such U.S. Registered Global Security, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by such U.S. Registered Global Security for all purposes under the applicable U.S. Indenture. Except as set forth below, owners of beneficial interests in a U.S. Registered Global Security will not be entitled to have the debt securities represented by such U.S. 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 U.S. Indenture.

Principal, premium, if any, and interest payments on debt securities represented by a U.S. Registered Global Security registered in the name of DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner of such U.S. Registered Global Security. None of the Corporation, the U.S. Trustees 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 U.S. Registered Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The Corporation expects that DTC, 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 U.S. Registered Global Security as shown on the records of DTC. The Corporation also expects that payments by participants to owners of beneficial interests in such U.S. 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 each U.S. Indenture, the Corporation and the applicable U.S. Trustees will treat the persons in whose names the debt securities issued thereunder are registered as the owners of such debt securities for the purpose of receiving payments of principal, premium, if any, and interest on such debt securities and for all other purposes whatsoever. Therefore, neither the Corporation, the U.S. 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 U.S. Registered Global Security.

If DTC is, at any time, unwilling or unable to continue as depositary under a U.S. Indenture and a successor depositary is not appointed by the Corporation within 90 days, the Corporation will issue the applicable debt securities in definitive form in exchange for the applicable U.S. 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 issued under a U.S. Indenture represented by one or more U.S. Registered Global Securities and, in such event, the Corporation will issue debt securities of such series in definitive form in exchange for the U.S. Registered Global Security or U.S. Registered Global Securities representing such debt securities. In either instance, an owner of a beneficial interest in a U.S. 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.

Canadian Unsubordinated Debt Indenture

(3) no condition or event shall exist as to the Corporation or the successor either at the time of or immediately after such consolidation, amalgamation, merger, transfer, sale or conveyance and after giving full effect thereto or immediately after the successor complying with the provisions of paragraph (1) above which constitutes or would with the passage of time constitute an event of default under the Canadian Unsubordinated Debt Indenture; and

Events of Default

The Canadian Unsubordinated Debt Indenture provides that the following constitute events of default (each an “Event of Default”) thereunder:

(1) default in payment of principal of or premium, if any, on any debt security issued under the Canadian Unsubordinated Debt Indenture when due;

(2) default in payment of any interest due on any debt security issued under the Canadian Unsubordinated Debt Indenture or default in the performance of certain covenants contained in the Canadian Unsubordinated Debt Indenture, and such default shall have continued for 30 days;

(3) an order is made or an effective resolution passed for the winding-up or liquidation of the Corporation (other than pursuant to and in compliance with provisions in the Canadian Unsubordinated Debt Indenture relating to successors);

(4) the Corporation makes a general assignment for the benefit of its creditors, or shall be declared bankrupt, or if a custodian, or a sequestrator or a receiver and manager or any other officer with similar powers shall be appointed for, or an encumbrancer takes possession of, the property of the Corporation or any substantial part thereof;

(5) any process of execution is enforced or levied upon any substantial part of the property of the Corporation and remains unsatisfied for a period of 60 days, as to moveable or personal property, or 90 days, as to immovable or real property, provided that such process is not in good faith disputed by the Corporation, or, if so disputed, the Corporation shall have given evidence satisfactory to the Canadian Trustee that it has available a sum sufficient to pay, in full, the amount claimed in the event that it shall be held to be a valid claim;

(6) the Corporation fails to make any payment at maturity, including any applicable grace period, in respect of any issue of Indebtedness in an aggregate amount in excess of the greater of 5% of Consolidated Equity (as defined below) and $100.0 million, or the equivalent thereof in any other currency, and such failure shall have continued for a period of 30 days after written notice thereof shall have been given to the Corporation by the Canadian Trustee, or to the Corporation and the Canadian Trustee by the holders of not less than 25% in aggregate principal amount of the outstanding debt securities under the Canadian Unsubordinated Debt Indenture;

(7) a default with respect to any Indebtedness, which default results in the acceleration of any issue of Indebtedness in an aggregate amount in excess of the greater of 5% of Consolidated Equity and $100.0 million, or the equivalent thereof in any other currency, without such Indebtedness having been discharged or such acceleration having been cured, waived, rescinded or annulled for a period of 30 days after written notice thereof shall have been given to the Corporation by the Canadian Trustee, or to the Corporation and the Canadian Trustee by the holders of not less than 25% in aggregate principal amount of the outstanding debt securities under the Canadian Unsubordinated Debt Indenture; and

(8) the Corporation neglects to carry out or observe any covenant or condition contained in the Canadian Unsubordinated Debt Indenture on its part to be observed or performed and, after the required notice has been given by the Canadian Trustee to the Corporation, the Corporation fails to make good such default within a period of 60 days, or such shorter period as would at any time, if continued, render any substantial part of the property of the Corporation liable to forfeiture, unless the Canadian Trustee shall have agreed to a longer period, and in such an event, within the period agreed to by the Canadian Trustee.

If an Event of Default has occurred under the Canadian Unsubordinated Debt Indenture, the Canadian Trustee may in its discretion and shall upon the request in writing of the holders of at least 25% of the aggregate

22

principal amount of the debt securities outstanding thereunder, subject to any waiver of default under the Canadian Unsubordinated Debt Indenture, by notice in writing to the Corporation declare the principal and interest on all debt securities then outstanding under the Canadian Unsubordinated Debt Indenture and other moneys payable thereunder to be due and payable.

If an Event of Default has occurred under the Canadian Unsubordinated Debt Indenture (otherwise than by default in payment of principal monies at maturity), the holders of not less than 66²⁄₃% of the principal amount of the debt securities outstanding thereunder shall have the power to instruct the Canadian Trustee to waive the default (provided that, if the Event of Default relates to a covenant applicable to a particular series or issue of debt securities issued under the Canadian Unsubordinated Debt Indenture only, then only the holders of not less than 66²⁄₃% of the principal amount of outstanding debt securities of that series or issue, as applicable, shall be entitled to waive the default). The Canadian Trustee, so long as it has not become bound to institute any proceedings under the Canadian Unsubordinated Debt Indenture, shall have the power to waive the default if, in the Canadian Trustee’s opinion, the same shall have been cured or adequate satisfaction made therefor.

If the Corporation fails to pay to the Canadian Trustee, after the same has been declared due and payable, the principal of and premium, if any, and interest on all debt securities then outstanding under the Canadian Unsubordinated Debt Indenture, the Canadian Trustee may, in its discretion, and shall upon the request in writing of the holders of not less than 25% of the principal amount of the debt securities outstanding under the Canadian Unsubordinated Debt Indenture, and upon being funded and indemnified to its reasonable satisfaction against all costs, expenses and liabilities to be incurred, proceed in its name as trustee to obtain or enforce payment of the said principal of, premium (if any) and interest on all outstanding debt securities under the Canadian Unsubordinated Debt Indenture together with other amounts due thereunder by any remedy or proceeding authorized by the Canadian Unsubordinated Debt Indenture or by law or equity as the Canadian Trustee in such request shall have been directed to take, or if such request contains no such direction, or if the Canadian Trustee shall act without such request, then by such proceedings authorized by the Canadian Unsubordinated Debt Indenture or by suit at law or in equity as the Canadian Trustee shall deem expedient.

Holders of debt securities issued under the Canadian Unsubordinated Debt Indenture may not institute any action or proceeding or exercise any other remedy authorized by the Canadian Unsubordinated Debt Indenture, including an action to enforce the Canadian Unsubordinated Debt Indenture or the debt securities issued thereunder, unless the Canadian Trustee shall have failed to act within a reasonable time after receipt by it of written notification of an Event of Default, and a request in writing of the holders of not less than 25% in principal amount of debt securities outstanding under the Canadian Unsubordinated Debt Indenture shall have been made calling for the Canadian Trustee to initiate enforcement proceedings and the holders have furnished to the Canadian Trustee, upon its request, indemnification to its satisfaction against all costs, expenses and liabilities to be incurred.

Defeasance

Under the Canadian Unsubordinated Debt Indenture, the Corporation shall be deemed to have fully paid, satisfied and discharged all the debt securities outstanding thereunder or all the debt securities of any series or issue outstanding thereunder, as applicable, when either:

(1) the Corporation has irrevocably deposited or caused to be irrevocably deposited with the Canadian Trustee as trust funds in trust for the purpose, an amount sufficient to pay, satisfy and discharge the entire amount of principal, premium (if any) and accrued and unpaid interest to the maturity date or any repayment date, as the case may be, of all the debt securities outstanding thereunder or all the outstanding debt securities of the applicable series or issue, respectively; or

(2) the Corporation has irrevocably deposited or caused to be irrevocably deposited with the Canadian Trustee as trust property in trust for the purpose, such amount of direct obligations of, or obligations the principal, premium (if any) and interest of which are guaranteed by, the Government of Canada or

of the United States of America as will, together with the income to accrue thereon without consideration of any reinvestment thereof, be sufficient to pay and discharge the entire amount of principal, premium (if any) and accrued and unpaid interest to the maturity date or any repayment date, as the case may be, of all the debt securities outstanding thereunder or all the outstanding debt securities of the applicable series or issue, respectively;

and in either event:

(3) the Corporation has paid or caused to be paid all other sums payable with respect to all the outstanding debt securities thereunder or all the outstanding debt securities of the applicable series or issue, respectively;

(4) the Corporation has delivered to the Canadian Trustee an officers’ certificate stating that all conditions precedent provided for under the Canadian Unsubordinated Debt Indenture relating to the payment, satisfaction and discharge of all the outstanding debt securities thereunder or all the outstanding debt securities of the applicable series or issue, respectively, have been complied with; and

(5) except in respect of taxes arising with respect to deposited funds or other provision for payment in respect of the applicable debt securities as provided for under the Canadian Unsubordinated Debt Indenture, for the payment of which the Corporation has deposited funds with the Canadian Trustee as trust funds in trust for such purpose, the Canadian Trustee shall have received an opinion of nationally recognized counsel to the effect that the holders of the outstanding debt securities under the Canadian Unsubordinated Debt Indenture or the holders of the outstanding debt securities of the applicable series or issue, respectively, will not be subject to any additional taxes as a result of the exercise by the Corporation of the defeasance option and that they will be subject to taxes, if any, including those in respect of income (including taxable capital gain), on the same amount, in the same manner and at the same time or times as would have been the case if such option had not been exercised.

Modification and Waiver

The Canadian Unsubordinated Debt Indenture provides that the Corporation and the Canadian Trustee may, without the consent of the holders of debt securities outstanding thereunder, execute, acknowledge and deliver indentures or instruments supplemental thereto which shall thereafter form part thereof for certain purposes, including: (a) establishing the terms and conditions attaching to a series or issue of debt securities thereunder; (b) mortgaging, pledging, transferring, assuring and confirming to or vesting in the Canadian Trustee, or charging in favour of the Canadian Trustee, any property or assets owned or acquired by the Corporation; (c) evidencing the succession, or successive succession, of successors to the Corporation and the covenants of and obligations assumed by such successors; (d) giving effect to any extraordinary resolution; (e) adding limitations or restrictions, thereafter to be observed, upon the amount, dates of maturity, issue or the purposes of an issue of debt securities under the Canadian Unsubordinated Debt Indenture or upon the dealing with the property of the Corporation, provided that the Canadian Trustee shall be of the opinion that such further limitations or restrictions shall not be prejudicial to the interests of the holders of debt securities issued under the Canadian Unsubordinated Debt Indenture; (f) adding to the covenants of the Corporation and providing for additional events of default; (g) providing that the terms of any covenant or other provision is applicable and has effect only so long as any one or more particular series or issue of debt securities remains outstanding under the Canadian Unsubordinated Debt Indenture or restricting the benefit of any covenant or other provision to one or more particular series or issue of debt securities outstanding under the Canadian Unsubordinated Debt Indenture, provided that the Canadian Trustee shall be of the opinion that the interests of holders of debt securities then outstanding thereunder shall not be prejudiced thereby; and (h) the correction or rectification of any errors, ambiguities or omissions in the Canadian Unsubordinated Debt Indenture.

The Canadian Unsubordinated Debt Indenture further provides that holders of debt securities outstanding thereunder and/or holders of debt securities of a series outstanding thereunder especially affected may, among other things, by extraordinary resolution: (1) agree to any modification, abrogation, alteration, compromise or

24

arrangement of the rights of the holders of debt securities outstanding thereunder and/or, subject to the Canadian Trustee’s prior approval, the rights of the Canadian Trustee against the Corporation or against its undertaking, property and assets or any part thereof; (2) direct or authorize the Canadian Trustee to exercise or refrain from exercising any power, right, remedy or authority given to it under the Canadian Unsubordinated Debt Indenture or the debt securities outstanding thereunder; (3) waive, and direct the Canadian Trustee to waive, any default on the part of the Corporation in complying with any provision of the Canadian Unsubordinated Debt Indenture or the debt securities outstanding thereunder either unconditionally or upon any conditions specified in such extraordinary resolution; and, in case any holder of debt securities outstanding thereunder shall have commenced any proceeding to enforce any remedy under the Canadian Unsubordinated Debt Indenture by reason of such default, restrain such holder from continuing such proceeding and to stay or discontinue the same, upon payment, in certain circumstances, of the reasonable and necessary costs, charges or expenses incurred by such holder in connection therewith; (4) sanction the exchange of the debt securities outstanding thereunder for securities of the Corporation or any other entity; and (5) assent to any modification, change in or omission from the provisions contained in the Canadian Unsubordinated Debt Indenture or in the debt securities outstanding thereunder which shall be agreed to by the Corporation and to authorize the Canadian Trustee to concur in and execute any supplemental indenture embodying such modification, change or omission.

Under the Canadian Unsubordinated Debt Indenture, an “extraordinary resolution”, with respect to debt securities outstanding thereunder or debt securities of a particular series outstanding thereunder, means a resolution passed, at a duly constituted meeting at which the holders of at least 25% of the principal amount of debt securities then outstanding thereunder and entitled to vote on the resolution are present in person or represented by proxy, by the favourable votes of the holders of not less than 66²⁄₃% of the principal amount of debt securities represented at the meeting and voted on such resolution, or instrument in writing signed by the holders of not less than 66²⁄₃% of the principal amount of all the debt securities outstanding thereunder or all the outstanding debt securities of the applicable series entitled to vote on the resolution.

If at any such meeting called for the purpose of passing an extraordinary resolution, the holders of 25% in principal amount of debt securities then outstanding under the Canadian Unsubordinated Debt Indenture are not present in person or represented by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by or on the requisition of holders of debt securities outstanding under the Canadian Unsubordinated Debt Indenture, shall be dissolved; but in any other case it shall stand adjourned to such date, being not less than 21 nor more than 60 days later, and to such place and time as may be appointed by the chairman. At the adjourned meeting, the holders of debt securities outstanding under the Canadian Unsubordinated Debt Indenture present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened and a resolution proposed at such adjourned meeting and passed by the requisite vote as provided under the Canadian Unsubordinated Debt Indenture shall be an extraordinary resolution under the Canadian Unsubordinated Debt Indenture notwithstanding that the holders of 25% in principal amount of debt securities then outstanding thereunder are not present in person or by proxy at such adjourned meeting.

Governing Law

The Canadian Unsubordinated Debt Indenture is and the debt securities issued thereunder will be governed by and construed in accordance with the laws of the Province of Alberta.

Global Securities

Unless otherwise indicated in an applicable prospectus supplement, the debt securities of a series issued under the Canadian Unsubordinated Debt Indenture may be issued in the form of one or more fully registered global debt securities (“Canadian Registered Global Security”) held by, or on behalf of, CDS Clearing and Depository Services Inc. or its successor (collectively, “CDS”) as depository of the Canadian Registered Global Securities (for its direct and indirect participants) and registered in the name of CDS or its nominee.

25

CDS will be responsible for establishing and maintaining book entry accounts for its participants having interests in Canadian Registered Global Securities. Participants will be responsible for establishing and maintaining book entry accounts for persons, other than participants, having interests in the Canadian Registered Global Securities. Except as described below, no purchaser of a debt security issued under the Canadian Unsubordinated Debt Indenture will be entitled to a certificate or other instrument from the Corporation or CDS evidencing that purchaser’s ownership thereof, and no owner of a debt security issued under the Canadian Unsubordinated Debt Indenture (other than participants) will be shown on the records maintained by CDS. Each purchaser of a debt security issued under the Canadian Unsubordinated Debt Indenture will receive a customer confirmation of purchase from the underwriter, dealer or agent, as the case may be, from whom such debt security is purchased in accordance with the practices and procedures of such underwriter, dealer or agent. The practices of such underwriters, dealers and agents may vary but generally customer confirmations are issued promptly after execution of a customer order.

Debt securities issued under the Canadian Unsubordinated Debt Indenture will be issued in fully registered form to participants and owners of such debt securities only if (i) CDS is no longer willing or able to continue as depository and the Corporation does not appoint a qualified successor; (ii) the Corporation, at its option, elects to terminate the book entry system through CDS; or (iii) in certain other circumstances.

Transfers of debt securities issued under the Canadian Unsubordinated Debt Indenture and represented by Canadian Registered Global Securities will be effected through records maintained by CDS for such Canadian Registered Global Securities or its nominee (with respect to interests of participants) and on the records of participants (with respect to interests of persons other than participants). Owners of debt securities issued under the Canadian Unsubordinated Debt Indenture who are not participants in the depository service of CDS, but who desire to sell or otherwise transfer such debt securities, may do so only through participants in the depository service of CDS. The ability of an owner of a debt security issued under the Canadian Unsubordinated Debt Indenture to pledge such debt security or otherwise take action with respect to such debt security (other than through a participant) may be limited due to the lack of a physical certificate.

As long as CDS or its nominee is the registered owner of a Canadian Registered Global Security, CDS or its nominee, as the case may be, will be considered the sole owner of the Canadian Registered Global Security for the purposes of receiving payments of interest and principal on each Canadian Registered Global Security. The Corporation expects that CDS or its nominee, upon receipt of any payment of principal or interest in respect of a Canadian Registered Global Security, will credit participants’ accounts, on the date principal or interest is payable, with payments in amounts proportionate to their respective interests in the principal amount of such Canadian Registered Global Security as shown on the records of CDS or its nominee at the close of business on the seventh business day prior to the applicable interest payment date, with respect to the payment of interest, and, at maturity, with respect to the payment of principal. The Corporation also expects that payments of principal and interest by participants to the owners of interests in such Canadian Registered Global Security held through such participants 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 participants. The responsibility and liability of the Corporation is limited to making payment of any principal and interest due on such Canadian Registered Global Securities to CDS or its nominee.

Any other rights of a holder of a debt security issued under the Canadian Unsubordinated Debt Indenture (including voting rights) must be exercised through a participant in CDS in accordance with the rules and procedures of CDS.

Where CDS or its nominee is not the registered owner of a Canadian Registered Global Security, as interest becomes due and payable on a fully registered debt security issued under the Canadian Unsubordinated Debt Indenture, the Corporation, either directly or through a trustee or paying agent, will send, prior to each interest payment date, by prepaid ordinary mail, a cheque for such interest (less any tax required to be withheld therefrom) payable to the order of the registered holder of such debt security appearing on the register maintained

26

by the Canadian Trustee at the close of business on the seventh business day prior to the applicable interest payment date, and addressed to such holder at such holder’s last address appearing on the register. In the event of non-receipt of any cheque for interest by the person to whom it is sent, the Corporation will issue to such person a replacement cheque for a like amount upon being furnished with such evidence of non-receipt and indemnity as it shall reasonably require.

PLAN OF DISTRIBUTION

We 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 to be negotiated with purchasers at the time of sale, which prices may vary as between purchasers and during the period of distribution. If the debt securities are offered on a non-fixed price basis, the underwriters’, dealers’ or agents’, as applicable, compensation will be increased or decreased by the amount by which the aggregate price paid for the debt securities by the purchasers exceeds or is less than the gross proceeds paid by the underwriters, dealers or agents, as applicable, to us.

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 TCPL in connection with the offering and sale of the debt securities, and will also set forth the terms of the offering of such debt securities, including the type of debt security being offered, the public offering price (or the manner of determination thereof if offered on a non-fixed price basis), the method of distribution of such debt securities, the proceeds to the Corporation, any underwriters’, dealers’ or agents’ fees, commissions or other items constituting underwriters’, dealers’ or agents’, as applicable, compensation and any concessions or discounts allowed or re-allowed or paid by any underwriters, dealers or agents to others. Only underwriters, dealers or agents so named in the prospectus supplement are deemed to be underwriters, dealers or agents, as the case may be, in connection with the debt securities offered thereby.

If underwriters purchase debt securities as principal, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, as described in the applicable prospectus supplement. The obligations of the underwriters to purchase those debt securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all the debt securities offered by the prospectus supplement if any of such debt securities are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid may be changed from time to time. The prospectus supplement will also set forth the intention of any underwriters, agents or dealers to engage in stabilizing, to

29

syndicate short covering transactions or penalty bids, or to undertake any other transactions during the offering that may stabilize, maintain, or otherwise affect the debt securities’ price. Such transactions, if commenced, may be interrupted or discontinued at any time without notice. Any underwriters, dealers 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, dealers or agents will not be obligated to do so and may interrupt or 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.

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, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.

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.

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.

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.

ENFORCEABILITY OF CIVIL LIABILITIES

The Corporation is a corporation incorporated under and governed by the Canada Business Corporations Act. Some of the directors and officers of the Corporation, and some of the experts named in this prospectus, are residents of Canada or otherwise reside outside the U.S., and all or a substantial portion of their assets, and a substantial portion of the Corporation’s assets, are located outside the U.S. The Corporation has appointed an agent for service of process in the U.S., but it may be difficult for holders of debt securities who reside in the U.S. to effect service within the U.S. upon those directors, officers and experts who are not residents of the U.S. It may also be difficult for holders of debt securities who reside in the U.S. to realize in the U.S. upon judgments of courts of the U.S. predicated upon the Corporation’s civil liability and the civil liability of the directors and officers of the Corporation and experts under U.S. federal securities laws.

The Corporation has been advised by its Canadian counsel, Blake, Cassels & Graydon LLP, that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws would probably be enforceable in Canada if the U.S. court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. The Corporation has also been advised by Blake, Cassels & Graydon LLP, however, that there is real doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.

The Corporation filed with the SEC, concurrently with its registration statement on Form F-10, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Corporation appointed

30

TransCanada PipeLine USA Ltd. as its agent for service of process in the U.S. in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Corporation in a U.S. court arising out of or related to or concerning an offering of debt securities under this prospectus.

AGENT FOR SERVICE OF PROCESS

Scott B. Bonham, Cheryl F. Campbell, Bill Johnson, John E. Lowe, Mary Pat Salomone, Thierry Vandal and Dheeraj Verma are directors of the Corporation who reside outside of Canada and each of these directors has appointed the Corporation as agent for service of process at 450 - 1st Street, S.W., Calgary, AB T2P 5H1. Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person who resides outside of Canada, even if the party has appointed an agent for service of process.

CERTAIN INCOME TAX CONSIDERATIONS

The applicable prospectus supplement may describe certain material Canadian federal income tax consequences to an investor who is a resident of Canada or who is a non-resident of Canada of the acquisition, ownership and disposition of 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 may also describe certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of any debt securities offered thereunder by an initial investor who is a U.S. person (within the meaning of the U.S. Internal Revenue Code of 1986), including, to the extent applicable, any such consequences relating to debt securities payable in a currency other than the U.S. dollar, issued at an original issue discount for U.S. federal income tax purposes or containing early redemption provisions or other special items.

RISK FACTORS

Investment in debt securities is subject to various risks including those discussed below and those risks inherent in the pipeline, power and natural gas storage industries. Prospective purchasers of the debt securities should consider carefully the risk factors contained in and incorporated by reference in this prospectus and in the applicable prospectus supplement relating to an offering of debt securities.

Discussions of certain risks affecting the Corporation in connection with its business are provided in TCE’s annual and interim disclosure documents filed with the various securities regulatory authorities, which are incorporated by reference in this prospectus.

Risks Relating to the Unsecured Nature of the Debt Securities

The debt securities will be unsecured debt of the Corporation and will be effectively subordinated to all existing and future secured debt of the Corporation, to the extent of the assets securing such debt. If the Corporation is involved in any bankruptcy, dissolution, liquidation or reorganization, the secured debt holders would be paid before the holders of debt securities receive any amounts due under the debt securities to the extent of the value of the assets securing the secured debt. In that event, a holder of debt securities may not be able to recover any principal or interest due to it under the debt securities.

Structural Subordination

The debt securities will not be guaranteed by any subsidiaries of the Corporation. Therefore, the debt securities will be effectively subordinated to all existing and future liabilities of the Corporation’s subsidiaries.

31

The creditors of those subsidiaries will have the right to be paid before payment on the debt securities from any cash received or held by those subsidiaries. In the event of any bankruptcy, dissolution, liquidation or reorganization of one of those subsidiaries, following payment by the subsidiary of its liabilities, the subsidiary may not have sufficient assets to make payments to the Corporation in its capacity as an equityholder of such subsidiary.

Liquidity Risk

The Corporation does not intend to list the debt securities on any stock exchange and there can be no assurance that there will be a secondary market for or liquidity in the debt securities. This may affect the pricing of the debt securities in the secondary market, the transparency and availability of trading prices, the liquidity of the debt securities, and the extent of issuer regulation. Any underwriters, dealers or agents to or through whom the debt securities are sold by the Corporation for public offering and sale may from time to time purchase and sell the debt securities in the secondary market or make a market for the debt securities, but such underwriters, dealers or agents will not be obligated to do so and there can be no assurance that any underwriter, dealer or agent will undertake any market making activities in respect of the debt securities.

Interest Rate Risks

Prevailing interest rates will affect the market price or value of the debt securities. The market price or value of the debt securities may decline as prevailing interest rates for comparable debt instruments rise, and increase as prevailing interest rates for comparable debt instruments decline.

Credit Ratings May Not Reflect All Risks of an Investment in the Debt Securities and May Change

Credit ratings may not reflect all risks associated with an investment in the debt securities. Any credit ratings applied to the debt securities are an assessment of the Corporation’s ability to pay its obligations. Consequently, real or anticipated changes in the credit ratings will generally affect the market value of the debt securities. The credit ratings, however, may not reflect the potential impact of risks related to structure, market or other factors discussed herein on the value of the debt securities. There is no assurance that any credit rating assigned to the debt securities will remain in effect for any given period of time or that any rating will not be lowered or withdrawn entirely by the relevant rating agency.

Risks Associated with Floating Rate Debt Securities

An investment in debt securities which are issued with a floating rate of interest entails significant risks not associated with investments in fixed rate debt securities. The resetting of the applicable rate on a floating rate debt security may result in lower interest compared to a fixed rate debt security issued at the same time. The applicable rate on a floating rate debt security will fluctuate in accordance with fluctuations in the instrument or obligation on which the applicable rate is based, which in turn may fluctuate and be affected by a number of interrelated factors, including economic, financial and political events over which the Corporation has no control.

Redemption of Debt Securities

If the debt securities are redeemable at the Corporation’s option, as provided in the applicable prospectus supplement, the Corporation may choose to redeem the debt securities from time to time, especially when prevailing interest rates are lower than the rate borne by the debt securities. If prevailing rates are lower at the time of redemption, a purchaser would not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the debt securities being redeemed. The Corporation’s redemption right also may adversely impact a purchaser’s ability to sell debt securities as the optional redemption date or period approaches.

32

Foreign Currency Risks

Debt securities denominated or payable in foreign currencies may entail significant risks. These risks include, but are not limited to, the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential liquidity issues in the secondary market. These risks will vary dependent upon the currency or currencies involved and, if applicable, will be more fully described in the applicable prospectus supplement.

In addition, any debt securities issued pursuant to the Canadian Unsubordinated Debt Indenture will be governed by and construed in accordance with the laws of the Province of Alberta. Any judgment obtained in Canada in respect of such debt securities will be expressed in Canadian currency as the Currency Act (Canada) provides that any reference to money in a legal proceeding in Canada shall be stated in Canadian currency and such judgment may be based on a rate of exchange on a date other than the date of payment.

Limited Protections Under the Indentures

While each Indenture contains terms intended to provide protection to the holders of the debt securities issued thereunder upon the occurrence of certain events involving significant corporate transactions, such terms will be limited and may not be sufficient to protect a holder’s investment in such debt securities. In particular, none of the Indentures:

(a) require the Corporation to maintain any financial ratios or specific levels of net worth, revenues, income, cash flow or liquidity;

(b) restrict the Corporation’s ability to repurchase or prepay any other of its securities or other indebtedness;

(c) restrict the Corporation’s ability to make investments or to repurchase or pay dividends or make other payments in respect of its common shares or other securities ranking junior to the debt securities;

(d) restrict the Corporation’s ability to enter into highly leveraged transactions; or

(e) require the Corporation to repurchase the debt securities in the event of a change in control.

As a result of the foregoing, when evaluating an investment in the debt securities, prospective purchasers should be aware that the terms of the Indenture pursuant to which such debt securities will be issued do not restrict the Corporation’s ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events that could have an adverse impact on an investment in such debt securities.

33

LEGAL MATTERS

Certain matters relating to the issue and sale of the debt securities will be passed upon on behalf of the Corporation by Blake, Cassels & Graydon LLP, as to matters of Canadian law, and White & Case LLP, as to matters of U.S. law. As to matters of Canadian law, White & Case LLP will rely upon the opinion of Blake, Cassels & Graydon LLP.

EXPERTS

The audited consolidated financial statements of TCE as of December 31, 2023 and 2022 and for each of the years in the three-year period ended December 31, 2023, have been incorporated by reference herein and in the registration statement in reliance upon the report of KPMG LLP, independent registered public accounting firm, incorporated by reference herein and in the registration statement, and upon the authority of said firm as experts in accounting and auditing.

As at the date of this prospectus, the partners and associates of Blake, Cassels & Graydon LLP, as a group, beneficially own, directly or indirectly, less than 1% of any class of securities of the Corporation or of TCE. In connection with the audit of TCE’s annual financial statements for the year ended December 31, 2023, KPMG LLP has confirmed that they are independent with respect to the Corporation and TCE within the meaning of the relevant rules and related interpretations prescribed by the relevant professional bodies in Canada and any applicable legislation or regulations and also that they are independent accountants with respect to the Corporation and TCE under all relevant U.S. professional and regulatory standards.

RELIANCE ON EXEMPTIONS FOR WELL-KNOWN SEASONED ISSUERS

The securities regulatory authorities in each of the provinces and territories of Canada have adopted substantively harmonized blanket orders, including Alberta Securities Commission Blanket Order 44-501 – Re Exemption from Certain Prospectus Requirements for Well-Known Seasoned Issuers, as varied by Alberta Securities Commission Variation of Blanket Order 44-501 (collectively with the equivalent local blanket orders in each of the other provinces and territories of Canada, as amended, modified or varied, the “WKSI Blanket Orders”). This prospectus has been filed by the Corporation in reliance upon the WKSI Blanket Orders, which permit “well-known seasoned issuers” or “WKSIs” (as such terms are defined in the WKSI Blanket Orders), to file a final short form base shelf prospectus as the first public step in an offering, and exempt qualifying issuers from certain disclosure requirements relating to such final short form base shelf prospectus. As of the date hereof, the Corporation has determined that it qualifies as a “well-known seasoned issuer” under the WKSI Blanket Orders.

The following documents have been or will be filed with the SEC as part of the registration statement of which this prospectus forms a part: the documents referred to under “Documents Incorporated by Reference”; consent of KPMG LLP; consent of Blake, Cassels & Graydon LLP; consent of White & Case LLP; powers of attorney from directors and officers of the Corporation; the Indentures; Statement of Eligibility of The Bank of New York Mellon on Form T-1 under the U.S. Unsubordinated Debt Indenture; and Statement of Eligibility of the Computershare Trust Company, N.A. on Form T-1 under the U.S. Subordinated Debt Indenture.

STATUTORY RIGHTS OF WITHDRAWAL AND RESCISSION

Unless provided otherwise in a prospectus supplement, set forth below is a description of a purchaser’s statutory rights.

Securities legislation in certain of the provinces and territories of Canada provides purchasers with the right to withdraw from an agreement to purchase securities. This right may be exercised within two business days after the later of: (a) the date that the issuer: (i) filed the prospectus or any amendment on SEDAR+ and a receipt is issued and posted for the document and (ii) issued and filed a news release on SEDAR+ announcing that the document is accessible through SEDAR+; and (b) the date that the purchaser or subscriber has entered into an agreement to purchase the securities or a contract to purchase or a subscription for the securities. In several of the provinces and territories, the securities legislation further provides a purchaser with remedies for rescission or, in some jurisdictions, revisions of the price or damages, if the prospectus and any amendment contains a misrepresentation or is not delivered to the purchaser, provided that the remedies for rescission, revision of the price or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. Purchasers should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for the particulars of these rights or consult with a legal advisor.

In an offering of convertible, exchangeable or exercisable debt securities, you are cautioned that the statutory right of action for damages for a misrepresentation contained in this prospectus is limited, in certain provincial and territorial securities legislation, to the price at which the convertible, exchangeable or exercisable debt securities are offered to the public under the prospectus offering. This means that, under the securities legislation of certain provinces and territories, if the purchaser pays additional amounts upon the conversion, exchange or exercise of the debt security, those amounts may not be recoverable under the statutory right of action for damages that applies in those provinces and territories. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for the particulars of this right of action for damages or consult with a legal adviser.

Indemnification of Certain Persons

Section 124 of the Canada Business Corporations Act (“CBCA”) and Section 6 of By-Law No. 1 of TransCanada PipeLines Limited (“TCPL”) provide for the indemnification of directors and officers of TCPL. Under these provisions, TCPL shall indemnify a director or officer of TCPL, a former director or officer, and may indemnify an individual who acts or acted at TCPL’s request as a director or officer or in a similar capacity of another entity (collectively, an “Indemnified Person”) against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the Indemnified Person in respect of any civil, criminal, administrative, investigative or other proceeding (other than in respect to an action by or on behalf of TCPL to procure a judgment in its favor) in which the individual is involved because of that association with TCPL or other entity, if the Indemnified Person fulfills the following two conditions: (a) he or she acted honestly and in good faith with a view to the best interests of TCPL or in the best interests of such other entity as applicable and (b) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he or she had reasonable grounds for believing that his or her conduct was lawful. In respect of an action by or on behalf of TCPL or such other entity to procure a judgment in its favor, TCPL, with the approval of a court, may indemnify an Indemnified Person against all costs, charges and expenses reasonably incurred by him or her in connection with such action if he or she fulfills the conditions set out in clauses (a) and (b) of the previous sentence. Notwithstanding the foregoing, an Indemnified Person is entitled to indemnification from TCPL in respect of all costs, charges and expenses reasonably incurred by him or her in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which he or she is made a party by reason of his or her association with TCPL or such other entity if he or she fulfills the conditions in clauses (a) and (b) of this paragraph and was not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done.

Insofar as indemnification for liabilities arising under the United States Securities Act of 1933, as amended (the “Securities Act”), may be permitted to directors, officers or controlling persons of TCPL pursuant to the provisions described above, or otherwise, TCPL has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

TCPL maintains directors’ and officers’ liability insurance with policy limits, subject to the insurance policy terms and conditions, of U.S.$200,000,000 in the aggregate, subject to a deductible in respect of corporate reimbursement of U.S.$10,000,000 for each loss and a separate policy with a limit of U.S.$100,000,000 for non-indemnifiable losses only. Generally, under this insurance TCPL is reimbursed for payments in excess of the deductible made under corporate indemnity provisions on behalf of its directors and officers, and individual directors and officers (or their heirs and legal representatives) are covered for losses arising during the performance of their duties for which they are not indemnified by TCPL. Noteworthy exclusions from coverage are: claims arising from illegal acts, those acts which result in illegal personal profit, violation of any fiduciary duty under the United States of America Employee Retirement Income Security Act of 1974, pollution damage (except for resultant shareholder actions), bodily injury, property damage or engineering professional services and claims brought by a director or officer against TCPL, or another director or officer or by TCPL against a director or officer except for shareholder derivative actions not assisted in by a director or officer of TCPL.

The foregoing is a description of the provisions of Section 124 of the CBCA and TCPL’s By-Law No. 1 regarding indemnification of directors and officers of TCPL and TCPL’s directors’ and officers’ liability insurance in effect as of December 5, 2024.

Additionally, directors and officers of TCPL are party to indemnity agreements with TCPL pursuant to which TCPL has agreed to indemnify such directors and officers from liability arising in connection with the performance of their duties. Such indemnity agreements conform with the provisions of the CBCA.
