Canada's environment minister says Saskatchewan will be subject to a federal carbon tax if it doesn't sign on to a national climate change plan by the fall.
Catherine McKenna says in a letter to her Saskatchewan counterpart, Dustin Duncan, that Saskatchewan is best positioned to design a carbon-pricing approach that works for the province.
``The other nine provinces have taken us up on that approach,'' she wrote. ``It's unfortunate that your government has not yet chosen to do the same.
``I remain hopeful that you will change course ahead of the Sept. 1 deadline for all provinces and territories to submit their carbon-pricing plans.''
Saskatchewan Premier Scott Moe said as recently as Friday that the province has not changed its mind about being the lone holdout on Ottawa's Pan-Canadian Framework on Clean Growth and Climate Change.
After a meeting with Prime Minister Justin Trudeau, Moe said the province has a plan of its own and only signs agreements it can honour.
McKenna said Saskatchewan will be subject to a carbon tax, whether it signs on or not.
``To be clear, we cannot accept your request not to price carbon in Saskatchewan,'' she said. ``In the event that your government does not adopt a price on pollution that meets our standard, we would have no choice but to ensure that a price on pollution applies in Saskatchewan, just as we would anywhere else in the country.''
The federal government would apply its carbon pricing in Saskatchewan and would ensure any revenues raised stayed in the province, she said.
Saskatchewan has already missed one deadline to sign on to the federal plan, which McKenna has said means the province won't get $62 million in funding for emissions-reduction programs.
