Alberta and Ontario proposed a 3,300-kilometer pipeline Monday to transport western Canadian oil to Sarnia, Ontario. According to Alberta Premier Danielle Smith, the project aims to reduce Canada’s reliance on U.S. infrastructure and open new export markets, reviving a concept abandoned nearly a decade ago.
What are the details of the proposed pipeline?
Premier Danielle Smith stated the pipeline would run from Hardisty, Alberta, to Sarnia, Ontario. It is designed to carry up to 500,000 barrels of oil per day, with the potential to reach 800,000 barrels. Smith noted the corridor could eventually extend to Canada’s Atlantic coast to facilitate oil exports to Europe.

Ontario Premier Doug Ford described the pipeline as a sound investment, regardless of whether financing is public or private. A feasibility study is planned for the project. Ford acknowledged that “there is still a lot of work ahead of us to deliver.”
Why is Canada seeking a sovereign oil route?
The move is driven by a need for energy security and a desire to bypass U.S. dependencies. Ontario’s Minister of Energy Stephen Lecce posted on social media that 50% of oil imports into Ontario currently run through a pipeline that cuts through the U.S. Lecce argued a sovereign route is necessary to connect Alberta crude to Sarnia, which is the country’s largest petrochemical hub and refinery.
Heather Exner-Pirot of the Macdonald-Laurier Institute identified an immediate threat: the Governor of Michigan has spent several years attempting to shut down Enbridge’s Line 5. This pipeline feeds Canadian oil to Sarnia via the U.S. Concerns regarding Line 5 intensified after 2017, when Enbridge disclosed gaps in the protective coating of the section beneath the Straits of Mackinac. A boat anchor strike in 2018 further increased fears of a major oil spill in the Great Lakes.
What hurdles could the project face?
The proposal faces significant obstacles including regulatory approvals, financing, and consultations with Indigenous populations. Daniel Béland, a political science professor at McGill University, called the project a “massive undertaking.” While Béland said it is technically feasible, he noted that the lack of final route and cost estimates makes the idea of reaching the Atlantic “quite speculative.”

The project mirrors the failed Energy East pipeline, which was abandoned in 2017. That project collapsed after years of environmental, regulatory, and political opposition, specifically including opposition in Quebec.
How does this fit into Alberta’s broader energy strategy?
This proposal coincides with other efforts to expand export capacity. That project involves partnerships with Calgary-based Pembina Pipeline and the federally owned Trans Mountain Corp.
Smith intends to double Alberta’s oil production to 8 million barrels a day over the next decade. She has attributed separatist sentiment to the policies of former Prime Minister Justin Trudeau. Alberta is scheduled to vote this fall on whether to hold an independence referendum.
