Montcalm — Election Outlook & Projection
Where this riding stands
The RidingWatch model currently projects the Bloc Québécois at 48% in Montcalm, 17 points ahead of the Liberals at 31%, with the Conservatives at 14%, the NDP at 5%, the Greens at 2%. Across 10,000 simulations the seat goes to the Bloc Québécois in >99% of them. The simulations put the Bloc Québécois’ share anywhere from 42% to 53%, and the Liberals' from 25% to 37%.
In April 2025 the Bloc Québécois won here with 47%, 20 points ahead of the Liberals. The Bloc Québécois also held it in 2021. Compared with the 2025 result, the current projection has the Conservatives down 9, the Liberals up 4, the NDP up 2 points. These shifts come from the national polling swing applied to this riding's past results — not from riding-level polling, which the model does not have.
The sitting member is Luc Thériault (Bloc Québécois), MP since 2019.
Rating: Safe Bloc Québécois — the Bloc Québécois leads by a margin the model treats as decisive on current polling. In practical terms, a 17-point projected margin is wider than the swings the model produces in most ridings; a different result would need a local shift that national polling doesn't currently show. No other party is within 10 points of the lead on these numbers, though the Liberals at 31% clear the model's 15% viability floor. Every vote counts toward a party's national total regardless of the local outcome.

About the Model
This projection is generated by the RidingWatch statistical model, which combines national polling data with historical election results to estimate vote shares and likely outcomes in each of Canada's 343 federal ridings.
The model begins with a weighted blend of results from the 2025 and 2021 federal elections, then applies the polling swing to each riding using a mostly-uniform (90/10 uniform/proportional) swing method — the national swing, adjusted by the province's pooled deviation where pollsters publish regional crosstabs. No pollster house effects are applied. Incumbency is not assumed: only first-term MPs (+1) and party leaders (+2) receive an adjustment. Uncertainty is estimated through 10,000 Monte Carlo simulations with correlated regional errors.
Projections are updated as new polling data becomes available. All estimates are probabilistic — they represent the most likely outcome given current information, not a guarantee of any result. Actual election outcomes depend on factors the model cannot fully capture, including local campaigns, turnout variation, and late-breaking events.
