OTTAWA — The fall economic statement included the first concrete steps to future-proof Prime Minister Justin Trudeau’s key climate legacy: carbon pricing. Time and time again, Conservative Party Leader Pierre Poilievre and his caucus have vowed to scrap the carbon price if elected. This cornerstone climate policy endured a challenge from Alberta, Ontario and Saskatchewan in Canada’s Supreme Court, which ultimately ruled that imposing the carbon price was constitutional. Trudeau has championed Canada’s carbon price on the international stage, including advocating for a global price at a carbon-pricing event he co-hosted at last year’s United Nations climate conference. …Companies have no assurance the carbon price will remain in effect. This long-term uncertainty puts a chill on investment in low-carbon technologies. In 2030, the carbon price is expected to be $170 per tonne of carbon dioxide equivalent.
