Canadian Prime Minister Justin Trudeau's Liberal Party suffered a significant defeat in a special election, losing a long-held seat in Montreal to the Bloc Québécois' Louis-Philippe Sauvé. This marks the second major electoral loss for the Liberals in just a few months, intensifying pressure on Trudeau to resign. Polls indicate declining support for Trudeau, with Conservative leader Pierre Poilievre planning to introduce a non-confidence motion against the government next week. The Bloc Québécois narrowly won the race by less than 250 votes. Trudeau acknowledged the defeat but reiterated his commitment to leading the party into the next election, scheduled for October 2025.
