**The Rosemont riding in the October 5, 2026 Quebec general election remains a tight contest between Parti Québécois candidate Pierre-Luc Brillant and Québec solidaire’s Gisèle Pouhe Njall, consistent with trader pricing that places them as the clear frontrunners while other candidates trail far behind.** The departure of longtime QS MNA Vincent Marissal, who left the party and announced he would not seek re-election, has opened the seat that QS held comfortably in 2022. Brillant, an actor, musician, and UDA vice-president running for the second time, emphasizes local priorities including reconstruction of Hôpital Maisonneuve-Rosemont alongside sovereignty and cultural issues. Pouhe Njall, announced in July, brings community work focused on social justice, education, and housing. Provincial polling shows the PQ competitive or leading overall, while 338Canada’s September 1 projection treats the riding as a near toss-up with a slight PQ edge. The nomination deadline of September 17 and the short campaign window leave limited time for major shifts, keeping the race centered on candidate profiles, local health and housing concerns, and the broader provincial contest between the PQ, QS, CAQ, and Liberals. Late developments such as debates or turnout patterns in Montreal ridings could still influence the final margin.
