The open seat in Louis-Hébert after longtime CAQ MNA Geneviève Guilbault declined to seek re-election has intensified competition among new candidates ahead of the October 5, 2026, Quebec general election. Provincial polling aggregates show the Parti Québécois holding a narrow lead over the CAQ, with the Conservatives and Liberals also in contention, while local projections from models like 338Canada continue to favor the CAQ nominee Marc-Antoine Bernier on the basis of historical riding strength. Trader consensus in the market, with Bernier at 44 percent and Chloé Fauchon of the PQ at 17 percent, reflects uncertainty over whether provincial momentum for the PQ or entrenched local support for the CAQ will prevail in this redistributed riding. Key variables include voter turnout among francophone households and any late shifts in party messaging on housing, education, and language issues.
