Souris—Moose Mountain — Election Outlook & Projection
Where this riding stands
The RidingWatch model currently projects the Conservatives at 77% in Souris—Moose Mountain, 64 points ahead of the Liberals at 13%, with the NDP at 8%, the Greens at 2%. Across 10,000 simulations the seat goes to the Conservatives in >99% of them. The simulations put the Conservatives' share anywhere from 70% to 85%, and the Liberals' from 7% to 19%.
In April 2025 the Conservatives won here with 84%, 74 points ahead of the Liberals. The Conservatives also held it in 2021. Compared with the 2025 result, the current projection has the Conservatives down 7, the Liberals up 3, the NDP up 3 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 Steven Bonk (Conservative), MP since 2021.
Rating: Safe Conservative — the Conservatives lead by a margin the model treats as decisive on current polling. In practical terms, a 64-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. Every vote counts toward a party's national total regardless of the local outcome.

About this riding
A southeastern Saskatchewan riding stretching from the Souris River valley near Estevan north through Weyburn and east to the Moose Mountain uplands along the Manitoba border. Estevan and Weyburn serve as the riding's principal towns, both historically tied to oil production and agriculture. Moose Mountain Provincial Park, set in the wooded hills of the Missouri Coteau, offers a landscape contrast to the surrounding open prairie. The riding encompasses some of Saskatchewan's most productive farmland, with grain, oilseed, and cattle operations dominating the rural economy. The Souris River winds through the southern portion before crossing into Manitoba and eventually joining the Assiniboine River. Significant oil reserves in the Bakken formation have shaped the regional economy, particularly around Estevan and the surrounding Energy City district. Small towns and grain elevators dot the landscape throughout.

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.
