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
5.8 pts
Half the margin: the share that would have had to move from first to second.
Third place vs. the margin
4,021 votes
New Democratic took fewer than the 7,737-vote margin.
Election-day polls won by others

3 polls ended in an exact tie.
Flip the seatHypothetical
It would have taken 3,869 voters switching from Liberal to Conservative — 5.8% of the 66,810 valid votes, 5.8 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 7,737 votes. Actual margin: 7,737.
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.
