Methodology
The Nanos seat projection makes use of a combination of historical election data, details on party and polling data to estimate and categorize the margins of victory at the riding and neighbourhood levels for all 338 Canadian federal ridings. The model predicted 86 per cent (289 of 338) of federal ridings correctly in the 2019 election.
In addition to party support, the model identifies which ridings are too close to call or have the potential to switch from one party to another.
The seat projection data updates every month in non-election cycles and every week during federal election periods.
