A court hearing for the Saskatchewan government to argue for an injunction to stop the Canada Revenue Agency from collecting millions in carbon levy money has been cancelled.

Federal Court in Vancouver did not provide an explanation for the cancellation or say when the case would be heard.

Premier Scott Moe鈥檚 government argues it鈥檚 unconstitutional for Ottawa to take from the province鈥檚 bank account, and that it鈥檚 unfair Saskatchewan has to pay.

Earlier this year, Saskatchewan stopped remitting the carbon levy on natural gas to Ottawa, after Prime Minister Justin Trudeau exempted home-heating oil users from paying.

Trudeau鈥檚 move was largely seen as helping those in Atlantic Canada, where home-heating oil is commonly used and where polls suggest the federal Liberals need to bolster support.

Court documents say Saskatchewan鈥檚 unpaid bill has grown to $56 million between January and April, and the revenue agency had tried to take $28 million through a bank order.

Ottawa has said it鈥檚 standing firm on getting the money back from Saskatchewan, noting the province is breaking federal emissions law by not paying.
