Windsor—Tecumseh—Lakeshore — Election Outlook & Projection
Where this riding stands
The RidingWatch model currently projects the Liberals at 46.5% in Windsor—Tecumseh—Lakeshore, 12.8 points ahead of the Conservatives at 33.7%, with the NDP at 17.8%, the Greens at 2%. Across 10,000 simulations the seat goes to the Liberals in 98% of them, the Conservatives in 2%. The simulations put the Liberals' share anywhere from 40% to 53%, and the Conservatives' from 28% to 40%.
In April 2025 the Conservatives won here with 46%, in a near tie with the Liberals on the rounded figures. That was a change from 2021, when the NDP took the seat. Compared with the 2025 result, the current projection has the Conservatives down 12.3, the NDP up 11.8, the Greens up 1.3 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 Kathy Borrelli (Conservative), MP since 2025.
Rating: Safe Liberal — the Liberals lead by a margin the model treats as decisive on current polling. In practical terms, a 12.8-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 Conservatives at 33.7% and the NDP at 17.8% 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.
