Ontario government launches constitutional challenge over carbon tax

The provincial government will be launching a constitutional challenge over the federal plan to tax provinces that don't come up with their own carbon pricing system.

The announcement was made this morning:

"Our contention is clear. Not only is the Trudeau-Liberal carbon tax unethical and unfair, it is also unconstitutional. Make no mistake the federal carbon tax will have its day in court, but it is already on trial," Attorney General Caroline Mulroney said.

The constitutional challenge is in addition to a decision from Premier Doug Ford to join Saskatchewan's legal battle.

Fighting the carbon pricing plan and eliminating the Ontario's cap and trade sytem were key elements of Ford's election campaign.

The PCs have budgeted $30 million for the challenge, but Mulroney believes it will cost less.
