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.
IIIHow close was it, really
Swing needed to flip
9.8 pts

Flip the seatHypothetical
It would have taken 4,434 voters switching from Liberal to Conservative — 9.7% of the 45,512 valid votes, 9.8 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

IVElection day versus advance

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.
