The Trans Mountain pipeline was established in October 1953 to create a reliable energy supply for Canada and the United States. The initial capacity was 120,000 barrels per day with three pump stations along the line and a marine loading dock. Since 1953, the pipeline’s capacity has been increased a number of times by twinning parts of the line and adding associated facilities. Today, the Trans Mountain pipeline carries approximately 300,000 barrels per day and operates the Westridge Marine Terminal facility.

Pipeline safety is our number one priority, and through the experience gained in 70 years of operation, Trans Mountain has developed a mature suite of programs to maximize pipeline safety. The most critical and responsible emergency preparedness strategy is spill prevention. However, in the case of a spill, we are prepared to respond quickly with detailed emergency procedures and trained professionals. We are committed to transparency involving spills that have occurred along its lines. Spills are reported and this information is publicly available.

The people who work for with us are dedicated and passionate. In some cases, multiple generations within a family have worked on the pipeline. Safety of the public, the environment and their colleagues is critically important for everyone who works at Trans Mountain.

We are also expanding our current 1,150-kilometre pipeline between Strathcona County, Alberta and Burnaby, BC. The expansion will create a twinned pipeline that will increase the nominal capacity of the system from approximately 300,000 barrels per day to 890,000 barrels per day.
