Regulator approves Trans Mountain toll settlement and 90% contract limit

The Canada Energy Regulator has approved a negotiated settlement that changes how tolls, tariffs and transportation services are managed on the Trans Mountain pipeline system.

The September 28 decision also lets Trans Mountain contract up to 90 per cent of system capacity to shippers, up from the previously approved 80 per cent. The regulator said the remaining capacity would still provide meaningful access to other shippers.

The settlement resolves disputes over how expansion-project costs are shared, so the associated RH-002-2023 proceeding has been cancelled. The regulator said no party with a commercial interest opposed the agreement and found its tolls just and reasonable.

Trans Mountain runs about 1,180 kilometres from Edmonton to Burnaby. The expansion completed in 2024 raised nominal capacity from roughly 300,000 to 890,000 barrels per day.
