 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.
