Alberta's government says it is "actively exploring" the use of every legal option, including a constitutional challenge or the use of the Alberta Sovereignty Act, to push back against federal legislation that will soon become law.
That legislation is Bill C-59, which would require companies to provide evidence to back up their environmental claims. It is currently awaiting royal assent.
As of Thursday, it was also what led the Pathways Alliance, a consortium of Canada's largest oilsands companies, to remove all its content from its website, social media and other public communications.
"For now, we have removed content from our website, social media and other public communications."
Asked about the move by reporters on Thursday, Prime Minister Justin Trudeau said that in a democracy, it's important that "people build their positions and their decisions around facts."
"Now, freedom of expression, freedom of people to share their points of view, is extraordinarily important. It's one of the foundations of a free and open democracy," Trudeau said.
"But we need to make sure that people are debating and discussing and basing their worldview on things that are anchored in truth and reality."
Pathways Alliance members react
The Pathways Alliance — which includes Canadian Natural Resources Ltd., Cenovus Energy Inc., ConocoPhillips Canada, Imperial Oil Ltd., MEG Energy Corp. and Suncor Energy Inc. — has publicly stated its pledge to cut greenhouse gas emissions from oilsands to net-zero by 2050.
