The federal government insisted Thursday that it’ll step in when necessary to ensure the Trans Mountain expansion project gets built, as it announced a restructuring of the process that saw the project approved.

Speaking in Calgary, Natural Resources Minister Jim Carr said the update to how major projects are assessed in Canada will restore public trust in the process, but that the government stands by its approval of Trans Mountain and won’t let any province obstruct its progress.

“The government of Canada, as this process plays through, will be absolutely alert to any attempts to delay this project,” said Carr. “If there is an attempt by any government to infringe on federal jurisdiction in the national interest, then the government of Canada will intervene.”

Tensions around the development of the controversial $7.4-billion pipeline project were heightened last week when the B.C. government announced plans for more consultations on oil-spill readiness and a limit on increased diluted-bitumen shipments until it’s confident in response measures.

On Thursday, B.C. Premier John Horgan, whose government has vowed to try to stop the Trans Mountain project, said the federal government’s announcement on restructuring environmental assessment raises questions on the process for past project approvals

“Does this say that the processes that were in place yesterday were adequate? Clearly the federal government doesn’t think so and many British Columbians don’t think so.”

The Alberta government has taken a strong stance against B.C.’s proposal, suspending electricity talks and halting B.C. wine imports in protest, while Alberta Premier Rachel Notley has called on the federal government to intervene.

On Wednesday, Kinder Morgan Canada Ltd. CEO Ian Anderson also called on the federal Liberals to move past words of support to actions of support.

“I’m expecting the federal government to help solve this dispute between the provinces,” said Anderson.

Carr said Thursday that Ottawa has already intervened on previous delays through the National Energy Board, which exempted Kinder Morgan from some delayed permits in Burnaby, and approved a dispute-resolution process for future permitting issues.

He said the federal government continues to talk with the provinces, including meetings today between officials from Ottawa and deputy ministers in B.C., but that no specific intervention is yet necessary from B.C.’s proposed consultations.

“They haven’t done anything yet, they’re consulting.

“The government of British Columbia is free to consult, the government of British Columbia cannot infringe on federal jurisdiction that impacts the national interest.”

Meanwhile, Environment Minister Catherine McKenna is working with her counterparts in Alberta and B.C. to try to find a solution to the trade war emerging between the two provinces over the pipeline expansion.

McKenna says she made separate phone calls this morning to Alberta Environment Minister Shannon Phillips and B.C. Environment Minister George Heyman to make clear that the federal government had clear authority to approve the Trans Mountain project and will exert that authority to make sure it gets built.

A spokeswoman for McKenna adds that the minister made clear the federal government won’t stand down and allow a provincial government to infringe on Ottawa’s constitutional authority to decide about interprovincial infrastructure projects such as pipelines.

McKenna says Canada isn’t wading into the trade dispute, but is working to get the pipeline built; she says the prime minister has also called the premiers and her deputy minister is in B.C. right now.
