Canada will impose a carbon price on provinces that do not adequately regulate emissions by themselves, Environment Minister Catherine McKenna says.
Speaking on the CTV broadcaster's Question Period, a national politics talk show, McKenna said the new emissions regime will be in place sometime in October, before a federal-provincial meeting on the matter.
She only said the government will have a "backstop" for provinces that do not comply, but did not address questions on penalties for defiance.
Canada's 10 provinces, which enjoy significant jurisdiction over the environment, have been wary of Ottawa's intentions and have said they should be allowed to cut carbon emissions their own way.
Prime Minister Justin Trudeau persuaded the provinces in March to accept a compromise deal that acknowledged the concept of putting a price on carbon emissions, but agreed the specific details, which would take into account provinces' individual circumstances, could be worked out later.

Canada's four largest provinces, British Columbia, Alberta, Ontario and Quebec, currently have either a tax on carbon or a cap-and-trade emissions-limiting system.
But Brad Wall, the right-leaning premier of the western energy-producing province of Saskatchewan, has long been resistant to federal emissions-limiting plans.
McKenna said provinces such as Saskatchewan can design a system in which emissions revenues go back to companies through tax cuts, which would dampen the impact of the extra cost brought by the carbon price.
McKenna added the government requires some uniformity in emissions reductions, but provinces can have different regulation methods.
