Trans Mountain Pipeline ULC - Trans Mountain Expansion

The Trans Mountain Expansion Project (TMX) is a proposal to expand the existing Trans Mountain pipeline system between Edmonton, AB and Burnaby, BC. It would include approximately 987 km of new pipeline, new and modified facilities, such as pump stations and tanks, and the reactivation of 193 km of existing pipeline. The Westridge Marine Terminal would also be expanded.

New pipeline segments would be added between Edmonton and Hinton, AB, Hargreaves, BC and Darfield, BC and Black Pines, BC and Burnaby, BC.

Some existing, but currently deactivated pipeline segments between Hinton, AB and Hargreaves, BC and Darfield and Black Pines, BC would be reactivated.
