The Supreme Court of Canada begins hearing appeals in three cases on Sept. 22 to determine whether Ottawa’s national carbon price is constitutional. Appellate courts in Saskatchewan and Ontario had previously upheld the law, but the Alberta Court of Appeal had ruled that it was unconstitutional and intruded on provincial powers.
Contrary to what critics of the federal carbon-pricing legislation say, neither the provinces’ authority to act on climate change nor the balance of the Canadian federation is in jeopardy.
