Explanation of Responses:

1. This Form 4 reports securities disposed of upon effectiveness of the merger contemplated by the Agreement and Plan of Merger, dated as of December 14, 2020, by and among TC PipeLines, LP, a Delaware limited partnership ("TC PipeLines"), TC PipeLines GP, Inc., a Delaware corporation, TC Energy Corporation, a Canadian corporation ("TC Energy"), TransCan Northern Ltd., a Delaware corporation, TransCanada PipeLine USA Ltd., a Nevada corporation and TCP Merger Sub LLC, a Delaware limited liability company and indirect wholly owned subsidiary of TC Energy ("Merger Sub");

2. (cont'd from Footnote 1) whereby of Merger Sub merged with and into TC PipeLines, with TC PipeLines continuing as the surviving entity (such merger, the "Merger"). Prior to the Merger, each deferred share unit ("DSU") represented the right to receive a cash equivalent value of one common unit of TC Pipelines pursuant to the terms of the TC PipeLines Deferred Share Unit Plan for Non-Employee Directors. As a result of the Merger, the underlying security for DSUs will convert to TC Energy common stock, but otherwise no changes were made to the terms of the DSUs. On March 2, 2021 (the day prior to the Merger), the closing price of one TC Energy common share was $43.32.

3. DSUs will be settled pursuant to the DSU Plan on the last business day of the first, second, third or fourth calendar quarter following the participant's separation from service, as elected by the participant in accordance with the terms of the DSU Plan.
