The 2021 column is Elections Canada's official transposition of the 2021 result onto these 2023 boundaries. ± is the change in each party's share. It is not "swing": with four or more competitive parties there is no single pair to swing between.

Flip the seatHypothetical

It would have taken 865 voters switching from Liberal to Conservative — 1.3% of the 65,317 valid votes, 1.4 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 1,728 votes. Actual margin: 1,728.

IVElection day versus advance

Only 60.9% of this riding's votes were cast at election-day polls. The rest were advance or special ballots. On election day alone, the Conservatives led here — the seat was decided by ballots cast before the day.

An association, not a cause. Voters who cast ballots before election day differed from those who turned out on the day. It does not say why. There is no poll-level turnout figure on this page: the elector count on a polling division includes people who voted in advance and were counted elsewhere.

VWhat kind of place this is

2021 Census, keyed to the 2023 representation order. Comparisons are against the median riding, not Canada as a whole. Each rule places this riding among all 343.
