In the Rosemont riding for Quebec’s October 5, 2026, general election, trader odds reflect a close contest between Parti Québécois candidate Pierre-Luc Brillant and Québec solidaire nominee Gisèle Pouhe Njall, with other party contenders trailing far behind. The seat, previously held by independent Vincent Marissal after strong QS performances in 2018 and 2022, became open after his retirement. Recent 338Canada projections show PQ and QS nearly tied in popular vote estimates, producing a toss-up outcome driven by the short campaign timeline, local priorities such as hospital reconstruction and housing, and broader provincial shifts in support for the main parties. Early candidate announcements and the absence of major riding-specific polling have kept implied probabilities tightly matched, with separation likely to emerge from upcoming leader visits, debates, or updated forecasts before nomination deadlines close in mid-September.
