They don't want proportional representation. If they did, they would have had it. Trudeau killed the electoral reform committee precisely because the NDP and Bloc insisted the would only accept PR and not Ranked Ballots (Trudeau's preference) and the Conservatives would prefer no change at all.

PR would force the Liberals to co-govern in coalition with the NDP basically forever. They don't want it. Their enthusiasm for Ranked Ballots is for the opposite reason: they realize they are the 2nd choice of "most" Canadians (or were until the last few months...). Given that, and the near-extinction event they suffered pre-2015 and the rise of Trudeau II, you can understand why they'd prefer that...
