**Guillaume Cliche-Rivard of Québec solidaire holds the leading position in trader pricing for the Saint-Henri–Sainte-Anne seat in the October 5, 2026, Quebec general election, reflecting his incumbency since the 2023 by-election and the riding’s urban Montreal character.** Recent polling projections from sources updated September 16 treat the contest as a close LIB/QS toss-up, with QS and Liberal vote shares clustered in the mid-30s. Cliche-Rivard benefits from name recognition and prior legislative work on housing and immigration issues that align with local priorities. Liberal candidate Benoit Clermont, a longtime resident and media producer, positions the party to challenge in a riding that leaned Liberal for decades before the by-election shift. CAQ candidate Anthony Lavoie trails in pricing consistent with the party’s weaker provincial standing. Nominations close on September 17 amid a short campaign window following the August 27 writ, with province-wide polling showing a competitive multi-party field and limited separation driven by ground organization and early positioning. Trader prices embed this balance while leaving room for movement from debates, turnout patterns among progressive and anglophone voters, or shifts in overall party momentum before election day.
