IDid this riding change?
Essentially no. Today's Marc-Aurèle-Fortin covers almost exactly the same ground as the Marc-Aurèle-Fortin riding it replaced.
How this is measured. Share of the current riding's area that came from each former riding, by intersecting the 2013 and 2023 boundary files. It is area, not population. Elections Canada counts 48 of 343 ridings as entirely unchanged.

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
14.2 pts
Half the margin: the share that would have had to move from first to second.
Third place vs. the margin
11,923 votes
Conservative took fewer than the 16,344-vote margin.
Election-day polls won by others

No poll ended in a tie.
Flip the seatHypothetical
It would have taken 8,173 voters switching from Liberal to Bloc Québécois — 14.2% of the 57,563 valid votes, 14.2 points — to change the result. No ballot was cast this way; this only moves votes between the top two.
Liberal29,928
Bloc Québécois13,584
Still Liberal by 16,344 votes. Actual margin: 16,344.
IVElection day versus advance
Only 67.3% of this riding's votes were cast at election-day polls. The rest were advance or special ballots.

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.
