Trans Mountain

About Us

Trans Mountain Corporation operates Canada’s only pipeline system transporting oil products to the West Coast. We have the capacity to deliver approximately 890,000 barrels of petroleum products each day through a pipeline system of more than 1,180 kilometres of pipeline in Alberta, British Columbia and 111 kilometres of pipeline in Washington state.

Trans Mountain also operates a state-of-the-art loading facility, Westridge Marine Terminal, with three berths providing tidewater access to global markets.

As a federal Crown corporation, Trans Mountain continues to build on decades of experience delivering operational and safety excellence through our crude oil pipeline system.

With our expanded pipeline system now in place, Trans Mountain provides enhanced direct access for Canadian crude oil to world markets. The expansion realizes a world-class system for oil transport, developed to Canada’s high standards within one of the most stringent regulatory regimes in the world, creating long-term economic benefits, enhanced marine protection, enhanced safety and emergency management capabilities, and enhanced skilled-worker capacity building in communities and Indigenous groups.


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