Green Party Leader Elizabeth May said the Carney government is not serious about climate change. May, who supported Carney's budget in December, has since questioned the prime minister's word after accusing him of a climate policy flip-flop.

"If we're serious about emissions reduction, then we have to actually revisit some of the measures that have been eliminated since (Carney) took over," May told The Canadian Press.

"They're miles from hitting any of the Paris Agreement targets, and the prime minister did recommit to me on the floor of the House on Nov. 17 that this government is committed to the Paris Agreement and achieving its targets. So the emissions reduction update, the so-called climate competitiveness strategy — there's lots of highfalutin titles for what boils down to...(no) climate plan.""
