Trans Mountain is expanding its current 1,150 km pipeline between Strathcona County, Alberta and Burnaby, BC. The expansion would create a twinned pipeline that would increase the nominal capacity of the system from 300,000 barrels per day to 890,000 barrels per day.
The federal government purchased the existing pipeline, along with the expansion project in May 2018 for $4.5B. The deal closed late August 2018.
On August 30, 2018, the Federal Court of Appeal issued a decision cancelling the Order-in-Council, which had approved the Certificate of Public Convenience and Necessity (CPCN) for the Expansion Project.
On September 26, 2018, the National Energy Board (NEB) (now Canadian Energy Regulator) announced a public hearing to carry out its reconsideration related to the Project. The Government directed the NEB to complete the reconsideration process and issue its resulting report no later than February 22, 2019. The NEB met that deadline and recommended approval of the project subject to 156 conditions.
On June 18, 2019, the Government of Canada approved the project for a second time. A Certificate of Public Convenience and Necessity (CPCN) was issued on June 21, 2019.
On August 21, 2019, Trans Mountain Corporation issued notice to its prime construction contractors to mobilize the equipment and workforce necessary to build the project. Construction began at the Westridge Marine Terminal in Burnaby, B.C. on August 22, and construction began in Alberta on December 3, 2019.
