The Parti Québécois would win a provincial election if it were held today, a new poll indicates, putting the support for the separatist party at 35 percent—an 18 percentage point lead over the governing CAQ.

The Arthabaska byelection that took place on Aug. 11 and led to a Parti Québécois (PQ) victory by former Radio-Canada journalist Alex Boissonneault, further solidified the momentum of the sovereigntist party as Quebec’s 2026 election approaches.
