* As more fully disclosed herein, the registrant’s common units were suspended from trading on the New York Stock Exchange effective March 3, 2021. A Form 25 was filed on March 3, 2021 to delist the registrant’s common stock from the New York Stock Exchange and to remove it from registration under Section 12(b) of the Exchange Act.

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

Emerging growth company ¨

On March 3, 2021, pursuant to that certain Agreement and Plan of Merger, dated as of December 14, 2020 (the “Merger Agreement”), by and among TC PipeLines, LP (“TC PipeLines”), TC PipeLines GP, Inc. (the “General Partner”), TC Energy Corporation (“TC Energy”), TransCan Northern Ltd. (“TransCan Northern”), TransCanada PipeLine USA Ltd., and TCP Merger Sub, LLC (“Merger Sub”) Merger Sub merged with and into TC PipeLines, with TC PipeLines continuing as the surviving entity and an indirect wholly owned subsidiary of TC Energy (the “Merger”).

As a result of the Merger, each common unit of TC PipeLines representing limited partner interests of TC PipeLines (each, a “Common Unit”) issued and outstanding immediately prior to the effective time of the Merger (excluding certain “Excluded Units,” as defined in the Merger Agreement) was cancelled in exchange for the right to receive from TC Energy 0.70 common shares of TC Energy (“TC Energy Shares” and such consideration, the “Merger Consideration”).

The issuance of the TC Energy Shares in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to TC Energy’s registration statement on Form F-4 (Reg No. 333-252004), declared effective by the Securities and Exchange Commission (“SEC”) on January 26, 2021. The proxy statement/prospectus in the registration statement contains additional information about the Merger.

The foregoing description of the Merger Agreement, the Merger and the other transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the full text of the Merger Agreement, incorporated by reference to Exhibit 2.1 to TC PipeLines’ Current Report on Form 8-K filed with the SEC on December 15, 2020.

In connection with the completion of the Merger, TC PipeLines notified the New York Stock Exchange (“NYSE”) that each outstanding Common Unit (other than Excluded Units) was cancelled in exchange for the right to receive the Merger Consideration and requested that NYSE withdraw the listing of the Common Units. Upon TC PipeLines’ request, the NYSE filed a notification of removal from listing on Form 25 with the SEC with respect to the delisting of the Common Units. The Common Units ceased being traded prior to the opening of the market on March 3, 2021, and will no longer be listed on NYSE. In addition, TC PipeLines intends to file with the SEC a Form 15 to terminate the registration of the Common Units under Section 12(g) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and suspend its reporting obligations under Section 15(d) of the Exchange Act.

The information set forth in Item 2.01, Item 3.01 and Item 5.01 of this Current Report on Form 8-K is incorporated into this Item 3.03 by reference.

At the effective time of the Merger and as further described in the Merger Agreement, each Common Unit (excluding Excluded Units) was cancelled in exchange for the right to receive the Merger Consideration. In connection with the Merger and at the effective time of the Merger, holders of Common Units immediately prior to such time (other than holders of Excluded Units) ceased to have any rights as unitholders in TC PipeLines (other than their right to receive the Merger Consideration pursuant to the Merger Agreement).

The information set forth in Item 2.01 of this Current Report on Form 8-K is incorporated into this Item 5.01 by reference.

As a result of the consummation of the Merger, at the effective time of the Merger, Merger Sub merged with and into TC PipeLines, with TC PipeLines continuing as the surviving entity and an indirect wholly owned subsidiary of TC Energy.

The information set forth under Item 2.01 of this Current Report on Form 8-K is incorporated into this Item 5.02 by reference.

At the effective time of the Merger, Jack Stark, Malyn K. Malquist and Peggy Heeg (collectively, the “Departing Directors”) resigned from the board of directors of General Partner (the “Board”). The decision of each of the Departing Directors to step down as a member of the Board was not the result of any disagreement with the General Partner or TC PipeLines on any matter relating to the operations, policies or practices of the General Partner or TC PipeLines, and was solely as a result of the Merger.

On March 3, 2021, TC PipeLines issued a press release announcing the consummation of the Merger. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information included in this Item 7.01 of this Current Report on Form 8-K, including the attached Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, is not subject to the liabilities of that section and is not deemed incorporated by reference in any filing under the Securities Act, except as shall be expressly set forth by specific reference in such filing.
