Item 1. Description of Registrant’s Securities to be Registered.

A complete description of the common shares (including the related rights under the shareholder rights plan) of the Registrant are contained under the caption “Information Concerning Holdco—Share Capital” in the Management Proxy Circular filed by TransCanada PipeLines Limited (“TransCanada”) with the Securities and Exchange Commission (the “Commission”) on Form 6-K on March 26, 2003 under the Securities Act of 1934, as amended (the “Exchange Act”). Such description is hereby incorporated by reference.

Effective on May 15, 2003 (the “Effective Date”), TransCanada, a Canadian public company whose common shares (including the related rights under shareholder rights plan) are registered under Section 12(b) of the Exchange Act, will complete an arrangement pursuant to a statutory reorganization (the “Arrangement”) whereby it will become a wholly owned subsidiary of TransCanada Corporation (the “Registrant”). The Arrangement will be effected pursuant to Articles of Arrangement that will be filed with the director appointed pursuant to Section 260 of the Canada Business Corporations Act. Pursuant to the Articles of Arrangement, each issued and outstanding common share of TransCanada (and related right under the shareholder rights plan) will be exchanged for one common share (and related right under the shareholder rights plan) of the Registrant and each new common share of the Registrant will be issued in a transaction exempt from registration under Section 3(a)(10) of the Securities Act of 1933, as amended. The shareholders of TransCanada approved, among other things, the Arrangement at a special meeting of shareholders held on April 25, 2003. As a result, each holder of common shares of TransCanada will become the owner of the same number and type of shares of the Registrant.

The Registrant’s common shares (including the related rights under the shareholder rights plan) will become registered under Section 12(b) of the Exchange Act as of the later of the receipt by the Commission of certification from the New York Stock Exchange or the filing of this Form 8-A with the Commission. The Registrant will assume certain registration statements filed by TransCanada prior to the Arrangement under the Securities Act of 1933, as amended, and all reports filed by TransCanada prior to the Arrangement under the Exchange Act.
