Alberta Premier Rachel Notley has scheduled a news conference for Thursday afternoon.
CBC News will carry a livestream of the speech, scheduled to start at 3:30 p.m. MT in the media room at the Alberta Legislature.
On Wednesday, Notley threatened legal and economic action against the British Columbia government, which this week proposed new restrictions on shipments of oil through the proposed expansion of the Trans Mountain pipeline from Alberta to the West Coast.
The premier also called an emergency cabinet meeting Wednesday to discuss Alberta’s options to strike back in its battle against the NDP government in B.C.
“The B.C. government took this action with no provocation and almost no warning,” Notley said. “The government of Alberta will not, we cannot, let this unconstitutional attack on jobs and working people stand.”
The meeting wrapped up after an hour without a decision.
When B.C. announced its intentions on Tuesday, Notley immediately termed the move “unconstitutional” and said Alberta would fight it.
“The B.C. government has every right to consult on whatever it pleases with its citizens,” Notley said at the time.
“It does not have the right to rewrite our Constitution and assume powers for itself that it does not have. If it did, our Confederation would be meaningless.”
Prime Minister Justin Trudeau is in Edmonton for a town hall meeting Thursday evening at MacEwan University.
In an interview Thursday morning on CBC Radio’s Edmonton AM, Trudeau said the federal government will stand by its 2016 approval of the $7.4-billion pipeline project.
“I’m not going to opine on disagreements between the provinces in this case,” Trudeau said.
“We’re just going to reiterate that the decision we made was in the national interest, and we’re going to move forward with that decision, which means we’re going to get the Trans Mountain pipeline built.”
