Trader consensus in the Terrebonne by-election heavily favors Tatiana Auguste at 61.5%, driven by recent internal Liberal Party polling showing her 15-point lead amid Bloc Québécois vulnerabilities in the Quebec riding. Nathalie Sinclair-Desgagné, the sitting MP who recently left the Bloc to sit as an independent on September 17, trails at 37.5%, with her party defection eroding base support and prompting questions about her Bloc renomination viability. Low odds for others like Maria Cantore reflect minimal campaign traction. Key catalysts include Auguste's strong local volunteer mobilization and a September 20 endorsement from Quebec Liberal Leader Marc Tanguay; the vote is slated for late October, with polls tightening urban turnout. Markets imply 62% chance Auguste flips the seat, aligning with historical by-election swings in similar ridings.
