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

Half the margin: the share that would have had to move from first to second.
Third place vs. the margin
17,292 votes

Flip the seatHypothetical
It would have taken 188 voters switching from Conservative to Green — 0.3% of the 59,084 valid votes, 0.3 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

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.
