Pipeline Profiles: Trans Mountain

Pipeline system and key points

Section updated June 2019

The Trans Mountain Pipeline, approximately 1150 kilometers long, transports crude oil and refined petroleum products from Edmonton, Alberta to refineries and terminals in British Columbia and Washington State. Crude oil is also shipped to offshore markets in Asia and the U.S. west coast via the Westridge Marine Terminal in Burnaby, British Columbia.

Trans Mountain started operations in 1953 and is unique among the major pipelines out of the Western Canadian Sedimentary Basin in that it ships the full spectrum of oils (from refined petroleum products to heavy crude oil) in a single line.

The Trans Mountain Pipeline has oil receipt points at Edmonton, Alberta and Kamloops, B.C. At Kamloops it also delivers products. At the Sumas delivery point, the Trans Mountain Pipeline connects with the Puget Sound Pipeline, owned by Trans Mountain Pipeline (Puget Sound) LLC, which delivers oil to four refineries on the west coast of Washington State.

At the Burnaby Terminal, connecting pipelines enable deliveries of crude oil and refined petroleum products to Parkland’s Burnaby Refinery and to Suncor’s Burrard refined products marketing terminal.

The Westridge Marine Terminal is located approximately three kilometres from the Burnaby Terminal. It facilitates marine exports from the Trans Mountain Pipeline to coastal refineries, such as those on the U.S. West Coast or in Asia.

Throughput and capacity

Section updated quarterly (early March, mid-May, mid-August and mid-November)

Note: The physical capacity of a pipeline is based on many factors such as the products being carried, direction of flow, pipeline pumping capacity, and maintenance work or other pressure restrictions. The actual physical capacity of the pipeline may, at times, be higher than the assumed operational capacity stated here.

Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available.


Section updated June 2019

A toll is the price charged by a pipeline company for transportation and other services. Tolls allow pipeline companies to safely operate and maintain pipelines. Tolls also provide funds for companies to recover capital (the money used to build the pipeline), pay debts, and provide a return to investors. The interactive graph below shows the tolls for key paths on the pipeline.

Open data can be freely used and shared by anyone for any purpose. The data for these graphs are available.

Trans Mountain currently operates under a three-year Incentive Toll Settlement (2016-2018 ITS). Tolls have fluctuated as over or under-recoveries of revenues are transferred to future years. Tolls are based on the quality of crude oil, the volumes and the specific pipeline path. Since January 2015, consideration of a shipper's previous delivery volumes has helped determine fair and equitable allocation of Trans Mountain system capacity.

Official NEB documents related to the traffic, tolls and tariffs for the Trans Mountain Pipeline can be found here: Trans Mountain Pipeline toll documents [Folder 552980].

Abandonment funding

Section updated June 2019

The Board requires all pipelines to set aside funds to safely cease operation of a pipeline at the end of its useful life. In 2016, Trans Mountain estimated it would cost $368 million to do this. These funds will be collected over 40 years and are being set aside in a trust.

Financial resource requirements

Section updated February 2018

The National Energy Board Act requires major oil pipeline companies to set aside $1 billion to pay for the costs of any incident that occurs, such as a spill. See sections 48.11 to 48.17 of the Act for more information. Trans Mountain Pipeline ULC demonstrated that is has financial resources in excess of $1 billion dollars. Official NEB documents related to the Trans Mountain’s financial resources can be found here: Trans Mountain financial resources documents [Folder 2949657].

Pipeline financial information

Section updated June 2019

Pipeline companies report important financial information to the Board quarterly or annually. A strong financial position enables companies to maintain their pipeline systems, attract capital to build new infrastructure, and meet the market’s evolving needs. The data in this table comes from Trans Mountain’s incentive toll settlement filings with the Board [Folder 552980].

Corporate financial information

Section updated June 2019

The Trans Mountain Pipeline is owned by the newly formed Trans Mountain Corporation, which is a federal Crown corporation. It is accountable to Parliament through the Canada Development Investment Corporation (CDEV). As a wholly-owned subsidiary of CDEV it is governed by an independent Board of Directors.

Financial regulatory audits

Section updated February 2018

The Board audits pipeline companies to confirm compliance with the National Energy Board Act, regulations, Board orders and Board decisions. Financial regulatory audits focus on toll and tariff matters such as detecting cross-subsidies. Trans Mountain’s last audit was completed in February 2008. Official NEB documents related to Trans Mountain’s financial regulatory audits can be found here: [Folder 571482].

Condition Compliance

Section updated September 2018

Every pipeline company in Canada must meet federal, provincial or territorial, and local requirements. This includes Acts, Regulations, rules, bylaws, and zoning restrictions. Pipelines are also bound by technical, safety, and environmental standards along with company rules, protocols and management systems. In addition to these requirements, the Board may add conditions to regulatory instruments that each company must meet. Condition compliance is monitored by the Board and enforcement action is taken when required. For a detailed list of conditions that Trans Mountain must meet, and their status, please see the condition compliance table and search for “Trans Mountain Pipeline Inc.”

Safety Performance

Section updated June 2019

The Board holds the companies it regulates accountable to protect the safety of Canadians and the environment. As part of this accountability, companies must report to the NEB events such as incidents and unauthorized third-party activities that happen without the pipeline company’s written consent. For a summary of pipeline incidents and unauthorized activities on the Trans Mountain Pipeline since 2008, visit the Safety performance dashboard and select “Trans Mountain Pipeline Inc.”

Emergency Management

Section updated June 2019

The NEB checks to make sure companies are keeping pipelines safe by doing inspections, in-depth safety audits, and other activities. Yet, even with these precautions, an emergency could still happen. Sound emergency management practices improve public safety and environmental protection outcomes, and provide for more effective emergency response.

The NEB holds its regulated companies responsible for anticipating, preventing, mitigating, and managing incidents of any size or duration. Each company must have an emergency management program that includes detailed emergency procedures manuals to guide its response in an emergency situation. We oversee the emergency management program of a regulated company’s projects as long as they operate.

The Board requires companies to publish information on their emergency management program and their emergency procedures manuals on their websites so Canadians can access emergency management information. To view Trans Mountains’ Emergency Response Plan, go to its Emergency Response Plans website.
