REGINA – Saskatchewan Premier Brad Wall says he has asked his Justice Ministry to look at legal options the province might have regarding the federal government’s intention to impose a carbon tax.

Wall says it’s not clear how Ottawa’s plan will take effect if Saskatchewan or other provinces say they’re not implementing a price on carbon.

The federal plan calls for a $10-per-tonne tax starting in 2018 and increasing to $50 per tonne by 2022.

Prime Minister Justin Trudeau has said carbon pricing will be imposed on provinces that don’t match the tax or implement a cap-and-trade system on emissions.

Wall says that kind of significant tax on the agriculture, mining and oil and gas industries would mean fewer jobs or people making less money.

The premier also says the federal government has not offered an economic assessment to show the impact on jobs or Canadian household costs.

Wall says Canadians need to address climate change, but he says that can be done through technological solutions and adaptation.
