Premier Brad Wall is once again pushing back against the proposed carbon tax plan.

The Saskatchewan Party has launched an online petition — titled, “Say NO to a Forced Federal Carbon Tax” — in an effort to gather as many signatures as possible ahead of a Dec. 9 meeting in Ottawa between Prime Minister Justin Trudeau, Canada’s premiers and indigenous leaders.

The pan-Canadian climate plan will be the main focus of the meetings’ agenda.

“I have already let the federal government know that I will not sign any agreement that includes a national carbon tax being imposed on Saskatchewan,” a post on Wall’s Facebook page reads.

The premier said Thursday in Saskatoon he believes he may be alone in fighting the carbon pricing plan.

“I do believe there are premiers that have concerns about jurisdictional issues,” he said. “Maybe not the concerns we have about the carbon tax, in particular, but about the federal government willing to impose anything nationally, in an area of shared jurisdiction.”

Saskatchewan is prepared to take the federal government to court, he said.

Nearly 20,000 people have signed the Saskatchewan Party’s petition so far.
