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
4.3 pts
Half the margin: the share that would have had to move from first to second.

Flip the seatHypothetical
It would have taken 2,998 voters switching from Conservative to Liberal — 4.3% of the 70,413 valid votes, 4.3 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.
