The Parti Québécois (PQ) has secured its third successive byelection win in Quebec, solidifying the momentum of the sovereigntist party as it approaches the 2026 provincial election.
The PQ victory by former Radio-Canada journalist Alex Boissonneault in the riding of Arthabaska on Aug. 11 is a setback to Premier François Legault’s ruling Coalition Avenir Québec (CAQ) party, which had held the seat since 2012.
