Scarborough Southwest — Election Outlook & Projection
Where this riding stands
The RidingWatch model currently projects the Liberals at 73% in Scarborough Southwest, 60 points ahead of the Conservatives at 13%, with the NDP at 10%, the Greens at 4%. Across 10,000 simulations the seat goes to the Liberals in >99% of them. The simulations put the Liberals' share anywhere from 67% to 81%, and the Conservatives' from 7% to 19%.
In April 2025 the Liberals won here with 61.5%, 30.9 points ahead of the Conservatives. The Liberals also held it in 2021. In the April 13, 2026 by-election the Liberals won with 69.6%, 50.8 points ahead of the Conservatives at 18.8% (Elections Canada figures, validated by the returning officer). The model uses that by-election result, not the 2025 result, as this riding's starting point, with Doly Begum (Liberal) as the sitting member; no incumbency adjustment is added on top of a by-election result. Compared with the by-election result, the current projection has the Conservatives down 5.8, the NDP up 4.1, the Liberals up 3.4 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 Doly Begum (Liberal), MP since 2026. Elected in the April 13, 2026 by-election.
Rating: Safe Liberal — the Liberals lead by a margin the model treats as decisive on current polling. In practical terms, a 60-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.

Projected Vote Share — Next Federal Election
Projected using a blended proportional-uniform swing model with incumbency adjustments. Based on the current national polling average and regional crosstabs as of 2026-09-14. Because this riding held a by-election on April 13, 2026, the model applies the swing to that result rather than to the April 2025 result.

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.
