Canadian Mainline Capacity Management Open Season

July 24, 2026 to August 20, 2026

TransCanada PipeLines Limited’s (“TCPL”) Canadian Mainline pipeline system is holding a New Capacity Open Season (“NCOS”) from July 2, 2026 to August 13, 2026.  

The NCOS service offering will require TCPL to increase its system capacity in the Eastern Triangle through the installation of new facilities (“Expansion Capacity”). This Capacity Management Open Season (the “Open Season”) is being conducted by TCPL to assess and potentially reduce the requirement for Expansion Capacity.

The Capacity Management Open Season will commence July 24, 2026 and run through August 20, 2026 closing at 11:00 a.m. MT (Calgary time).
