Conservative Leader Pierre Poilievre kicked off parliament's return on Monday by calling for Prime Minister Justin Trudeau to “axe the tax,” while Trudeau defended the carbon pricing scheme as necessary for climate response and rebates. Trudeau also took aim at the NDP, accusing the party of trying “to save themselves” after NDP Leader Jagmeet Singh pulled out of a political pact with the Liberal government just weeks ago. “As soon as hard things got hard, they turned tail and ran,” Trudeau said.
