Trans Mountain Expansion Project

The Trans Mountain Expansion Project (TMX) involved the construction (or twinning) of a second pipeline along the route of the existing Trans Mountain pipeline. TMX runs from Edmonton, Alberta, to the Westridge Marine Terminal in Burnaby, British Columbia.

TMX at a glance

The Government of Canada acquired TMX from Kinder Morgan in 2018. This was a serious and necessary investment made in the national interest. The completion of this important infrastructure project is making Canada and the Canadian economy more resilient by diversifying global market access for our resources.

TMX began operations in May 2024, and the pipeline is delivering on its potential to reach offshore markets, generating revenue for regional and national economies. The federal government does not intend to be the long-term owner of the project, and it will launch a divestment process in due course.

Project conditions

TMX is subject to 156 binding conditions from the Canada Energy Regulator covering the entire lifecycle of the project. These conditions focus on areas including environmental protection, emergency preparedness and response, engineering and safety, potential impacts to Indigenous groups, and administrative oversight of the project.

Project benefits

Now complete, the pipeline has and will continue to benefit our economy and Canadians by:

Having provided tens of thousands of good, middle-class jobs during construction
Opening new markets for Canadian energy exports, reducing our reliance on a single customer, and ensuring that Canada receives fair market value for its resources while maintaining the highest environmental standards
Increasing the price Canadian producers get for their oil by helping to narrow the price differential between Canadian benchmarks and the North American benchmark
Significantly increasing the royalties and tax revenues that all levels of government receive
- According to an independent study TMX is expected to add $9.2B in GDP and $2.8B in tax revenues between 2024 and 2043
Contributing to global and regional energy security by providing a secure, long-term supply of energy
Being an integral long-term part of Canada’s energy infrastructure
Creating economic benefits for many Indigenous groups through contracting, financial compensation, and employment and training opportunities
- Trans Mountain Corporation (TMC) has entered into 69 Mutual Benefit Agreements with 81 Indigenous groups valued at over $650M
- TMC provided over $6B in contracts to Indigenous-led ventures during construction
- Approximately 10% of all people hired by TMC and its contractors since the project began construction are Indigenous people
Ensuring that Indigenous groups have a meaningful role in monitoring the operations of TMX through the Indigenous Advisory and Monitoring Committee
