Middlesex—London — Election Outlook & Projection
Where this riding stands
The RidingWatch model currently projects the Liberals at 45.5% in Middlesex—London, 4.1 points ahead of the Conservatives at 41.4%, with the NDP at 11.1%, the Greens at 2%. Across 10,000 simulations the seat goes to the Liberals in 74% of them, the Conservatives in 26%. The simulations put the Liberals' share anywhere from 39% to 51%, and the Conservatives' from 35% to 47%.
In April 2025 the Conservatives won here with 52%, 10 points ahead of the Liberals. That was a change from 2021, when the Liberals took the seat. Compared with the 2025 result, the current projection has the Conservatives down 10.6, the NDP up 7.1, the Liberals up 3.5 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 Lianne Rood (Conservative), MP since 2019.
Rating: Lean Liberal — the Liberals hold a narrow projected lead. In practical terms, a 4.1-point margin is inside the range where turnout, candidates and local issues regularly decide the result. Within 10 points of the lead: the Conservatives (41.4%). 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.
