**Taschereau's Québec solidaire incumbent Étienne Grandmont holds a narrow lead in trader pricing at 48.5 percent, with the field fragmented across major parties in the October 5, 2026 provincial vote.** Recent developments include the Parti québécois replacing Vincent Marissal—briefly named then withdrawn over ethics concerns tied to a housing allowance—with Christian Savard, an urban-planning veteran. This late switch, occurring days after the writ drop, has introduced volatility into PQ prospects. Projections from sources such as 338Canada place QS in the low-to-mid 30s on popular vote, ahead of PQ, CAQ, PLQ, and PCQ contenders, consistent with Taschereau’s left-leaning history on the new electoral map. Local priorities around housing affordability, transit, and cost of living, combined with Grandmont’s incumbency and the multi-candidate split, keep implied probabilities clustered and sensitive to campaign momentum or further candidate developments.
