Canadian Mainline Capacity Management Open Season

July 31, 2025 to August 20, 2025

TransCanada PipeLines Limited’s (“TCPL”) Canadian Mainline pipeline system is holding a New Capacity Open Season (“NCOS”) from July 25, 2025 to August 14, 2025.  As a result of the NCOS, TCPL will be required to increase its system capacity in the Eastern Triangle (“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 related to the NCOS.
