The original Trans Mountain Pipeline was built in 1953 andcontinues to operate safelytoday. The Expansion is essentially a twinning of this existing 1,150-kilometre pipeline between Strathcona County (near Edmonton), Alberta and Burnaby, BC. It will create a pipeline system with the nominal capacity of the system going from approximately 300,000 barrels per day to 890,000 barrels per day.

Here are some quick facts about the expansion:

  • It will be approximately 980 km ofnew pipeline
  • 73 per cent of theroutewill use the existing right-of-way, 16 per cent will follow other linear infrastructure such as telecommunications, Hydro or highways and 11 per cent will be new right-of-way
  • It will include 193 km ofreactivated pipeline
  • 12 newpump stationswill be built
  • 19 new tanks will be added to the existing storage terminals in Burnaby (14), Sumas (1) and Edmonton (4)
  • Three new berths will be built atWestridge Marine Terminalin Burnaby. Once the new berths are completed and in service, the number of tankers loaded at the Westridge Marine Terminal could increase to approximately34 per month.
  • The existing pipeline will carry refined products, synthetic crude oils, and light crude oils with the capability for heavy crude oils
  • 新的管道将携带heavier oilswith the capability for transporting light crude oils
  • Engagementwith communities,局域网downers, stakeholders andIndigenous communitieshas been ongoing since 2012 and will continue through to operation
  • Environmental protection planshave been developed along the entire route.Volume 5Volume 6of the Facilities Application cover the environmental assessment and protection planning. We will continue to conductfield studiesalong the route as required.
  • It’s expected to cost approximately $12.6* billion.
  • Expected in-service date is December, 2022.
  • 它会创造benefitsincluding new short- and long-termjobs, job-relatedtraining opportunities和increases in taxes collected by all three levels of government
  • To date, Trans Mountain and our contractors havehired approximately 9,300 peopleto work on the Expansion Project.
  • The combined impact on government revenue for construction and the first 20 years of expanded operations is $46.7 billion; revenues that can be used for public services such as health care and education – British Columbia receives $5.7 billion, Alberta receives $19.4 billion and the rest of Canada receives $21.6 billion.*

Why expand?

Tranbetway体育下载s Mountain扩展项目将必威体育精装版app下载有助于确保加拿大为其石油获得全额价值。每个人都将受益。工人将在12.6亿美元建设项目期间受益。石油生产商将获得更多收入的产品。政府将从石油收集更多的税收收入。这些收入有助于使所有加拿大人受益的服务。

Currently, nearly all the oil produced in Western Canada goes to one market, the United States Midwest. However, there’s a limit to how much oil this market needs. For much of the last decade, Canada has been selling into the United States at a discount to the world price for similar oil products.

The simple truth is that Canada’s oil will fetch a better price if we give ourselves the option of shipping more of it via Trans Mountain’s Pacific tidewater terminal in Burrard Inlet. Canada will earn more on every barrel of oil that’s piped west compared to those sold to our existing customers in the United States Midwest market, a differential that exists regardless of the price of oil. The Project will allow Canadian oil to be delivered to international markets and, as a result, Canada will earn approximately $3.7 billion more per year.

Independent estimates conclude oil producer revenues will increase by $73.5 billion over 20 years of operations and Canada will earn $46.7 billion in additional taxes and royalties to federal and provincial governments.


Who’s involved?


These oil producers have made significant 15- and 20-year commitments that add up to roughly 80 per cent of the capacity in the expanded Trans Mountain Pipeline:

  • Athabasca Oil Corporation
  • BP Canada Energy Trading Company
  • Canadian Natural Resources Limited
  • Cenovus Energy Inc.
  • 德文加拿大公司
  • Husky Energy Marketing Inc.
  • Imperial Oil Limited
  • MEG Energy Corp.
  • PetroChina Canada Limited
  • Suncor Energy Marketing Inc.
  • Teck Canadian Energy Sales Ltd.
  • Tesoro Canada Supply and Distribution Ltd.
  • Total E&P Canada Ltd.

Pipeline Alternatives

Pipelines are proven to be the safest and most efficient method to move petroleum products over great distances on land. Petroleum products can also be shipped by tanker trucks or railcars.


每一天,公司的成员Canadian Energy Pipeline Association(CEPA) move enough crude oil and petroleum products through pipelines to fill 15,000 tanker truckloads and 4,200 railcars. The existing Trans Mountain pipeline system moves the equivalent of about 1,400 tanker truckloads or 441 tanker railcars daily. Expanding the Trans Mountain pipeline results in safer, more efficient and more economic shipment of oil between Alberta and BC.

Previous Expansion

This is not the first expansion of the Trans Mountain line. In fact, since operation began in 1953, the capacity of the pipeline system has been increased numerous times, with the initial expansion in 1957. The most recent expansion project took place between 2006 and 2008 with the construction of 13 new pump stations and modifications to existing stations. Also during this time, theAnchor Loop projectadded 160 kilometres of new pipe through Jasper National Park and Mount Robson Provincial Park between Hinton, Alberta and Hargreaves, BC.
