What is the timeline and scope of Trans Mountain's planned second open season and associated capacity expansion?

Trans Mountain Corp. plans a second open season in July this year, to be conducted 'quickly' with the goal of completing the associated expansion before Q1 of 2027; the company has already pre-ordered equipment for the project, and the expansion aims to raise system capacity to nearly 1.2 million barrels per day by 2029 through a two-phase process.

Why is Trans Mountain pursuing further expansions, and how does the pipeline support Canada's broader energy export strategy?

The pipeline enables Canadian oil producers to ship significant volumes to Asia, reducing near-total dependence on the US as a customer; this aligns with the federal government’s and Alberta’s joint push to diversify exports away from the US and increase energy production, including proposals for a new million-barrel-a-day pipeline to the BC coast and accelerated approvals for major projects.
