In split decision, Supreme Court says the federal carbon price is constitutional
OTTAWA — The Supreme Court of Canada ruled Thursday that the national price on pollution is entirely constitutional, upholding a pivotal piece of the Liberal climate-change plan.
The case brings a legal end to a years-long battle between Ottawa and many provinces over a carbon tax, and prompted Saskatchewan Premier Scott Moe to start looking at a homegrown carbon-pricing mechanism and Alberta Premier Jason Kenney to nudge open the door to doing so too.
Saskatchewan, Ontario and Alberta challenged the Liberal government’s 2018 Greenhouse Gas Pollution Pricing Act in court, arguing it was a federal overreach into provincial jurisdiction over everything from taxes and the environment to natural-resource development.
On Thursday all three were on the losing end, as the court declared Ottawa has the constitutional authority to impose a minimum price on greenhouse-gas emissions.
