CTV News: 'Premier Jason Kenney has filed his defence in a defamation lawsuit brought against him by environmental groups over his remarks on the release of an inquiry into supposed misinformation about Alberta's energy industry. And Kenney doubled down on his attacks on such groups Friday, blaming them for making the world more dependent on oil from Vladimir Putin's Russia. “They should apologize,” Kenney said at a press conference. “They should apologize for allowing the world's worst regimes to have a larger share of global energy markets.”'
