Ontario's top court is set to release a decision Friday on whether the federal government can impose a carbon tax on provinces it believes aren't doing enough to fight climate change.
The Court of Appeal heard arguments about the federal carbon tax over a period of four days in April, with the Ontario government saying it is unconstitutional and can't be legally enforced.
In a rare move, the court allowed the legal battle to be televised — the first time in more than a decade cameras were allowed into an appeal court to livestream an event.
Lawyers for the province argued the tax would allow Ottawa to step into areas of provincial authority. Ontario Premier Doug Ford has dubbed it "the worst tax ever."
