On Thursday, Alberta Premier Jason Kenney and Saskatchewan Premier Scott Moe both expressed their disappointment about the Supreme Court of Canada’s ruling which upheld Prime Minister Justin Trudeau’s carbon tax. Both provinces argued that the federal levy was unconstitutional and infringed on provincial rights. Premier Kenney announced his dissatisfaction with the ruling during a Thursday morning press conference and promised to continue battling the federal government on the matter through other means. “We are obviously disappointed with that decision. The Supreme Court ignored the Alberta Court of Appeals warning and discovered a new federal power that erodes provincial jurisdiction and undermines our constitutional federal system,” Kenney said.
