CALGARY - Canada announced plans to build a new oil pipeline from Alberta to the Pacific coast, which would give the world's fourth-largest oil producer greater capacity to export to Asia and ease its reliance on the US.

Prime Minister Mark Carney made the announcement in Calgary alongside Alberta Premier Danielle Smith, whose government said construction of the one-million-barrel-a-day pipeline would begin as early as September 2027.

The plan marks the culmination of months of political wrangling and compromise on all sides. It represents the Carney government's attempt to balance Canada's environmental ideals with the economic reality posed by US President Donald Trump's tariffs policy.

"We’ve agreed the time for action is now," said Carney.

The pipeline could make Canada a major global energy supplier, as Asia's top importers seek oil from outside the Middle East in the wake of the Iran conflict.

No cost estimates have been released for the pipeline, which will be built by government-owned Trans Mountain Corp in coordination with Pembina Pipeline Corporation to transport crude from Alberta's oil sands to British Columbia's southwest.

The federal government through Trans Mountain and the government of Alberta through its Alberta Petroleum Marketing Corporation would be majority owners of the pipeline. Pembina would have a 10% stake through construction, with the opportunity for up to an additional 10% once the project enters operation.

Smith said funding details of the project are still being negotiated.

The plan has been formally submitted by the provincial government to Canada's major projects office for potential regulatory fast-tracking.

PIPELINE HURDLES

Canada's oil output, which in 2026 is expected to exceed last year's record of 5.3-million bpd, currently has only one way to access Asian markets, the Trans Mountain pipeline, which runs along a similar route to the proposed new pipeline.

An expansion of the Trans Mountain pipeline was completed in 2024, seven years after Kinder Morgan threatened to cancel it due to heavy environmental and Indigenous opposition.

Ottawa bought the Trans Mountain system for C$4.5-billion ($3.15-billion) in 2018 to finish the expansion. Construction delays and budget overruns pushed its price tag to C$34-billion over four years.

Industry representatives have said regulatory uncertainties remain a major risk to crude oil pipeline construction in Canada, and no private company has expressed interest in taking a majority stake in Alberta's proposal.

Canada's environmental policies, especially under Liberal former Prime Minister Justin Trudeau, had stoked anger in oil-rich Alberta and fueled a nascent separatist movement. Carney has been seeking to improve relations with Alberta and last October signed an agreement to drop certain climate regulations and help the province grow its energy sector.

In a separate deal signed with British Columbia on Thursday, Carney committed to retaining an existing federal ban on oil tankers along the northwest coast. He also committed to help fund infrastructure upgrades aimed at expanding the capacity at the Roberts Bank Terminal, part of the port of Vancouver, while also pledging to accelerate the building of new liquefied natural gas projects in British Columbia.

British Columbia Premier David Eby had strongly opposed the idea of a northwest oil pipeline route owing to concerns about the risk of an oil spill in the ecologically fragile area. On Thursday he appeared to open the door to a pipeline going through his province, as long as the tanker ban remains in place.

Carney has said any new crude pipeline must be developed in partnership with Indigenous communities, and is also dependent on the oil industry building a large-scale carbon capture and storage project.

On Thursday, Alberta’s government said it is close to finalizing a tripartite agreement with Ottawa and the Oil Sands Alliance industry group that will pave the way for the carbon capture project to move ahead. Details of this agreement are expected to be released in the coming days.
