OTTAWA — A poll showing the Conservatives leading among young voters struck the Quebec political scene like lightning this week. And it’s all the more remarkable in a province that remains generally wary of Conservative Leader Pierre Poilievre.

In October, all eyes were on the Bloc Québécois and its leader Yves-François Blanchet, who had threatened to overthrow the Trudeau government if two bills were not passed, with one of them aiming to increase old age security benefits for everyone aged 65 and over.
