Trans Mountain Corp.


Trans Mountain Corp. operates Canada’s only pipeline system transporting oil products to the West Coast. We deliver approximately 300,000 barrels of petroleum products each day through 1,150 km of pipeline in Alberta and British Columbia, and 111 km of pipeline in Washington state.

The Trans Mountain Expansion Project will provide increased capacity to support Canadian crude oil production growth and ensure access to global energy markets. The largest project in the pipeline’s history, it involves installing approximately 980 km of new pipeline, new and modified facilities including pump stations and terminals, and a new dock complex at the Westridge Marine Terminal in Burnaby, British Columbia. 

As a federal Crown corporation, Trans Mountain Corporation will continue to build upon Trans Mountain’s 65 years of experience delivering operational and safety excellence through our crude oil pipeline system.

We are accountable to Parliament through the Canada Development Investment Corp. (CDEV). As a wholly-owned subsidiary of CDEV, we are governed by an independent Board of Directors.
