IDid this riding change?
Essentially no. Today's Lac-Saint-Louis covers almost exactly the same ground as the Lac-Saint-Louis 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
21.9 pts
Half the margin: the share that would have had to move from first to second.
Third place vs. the margin
2,330 votes
Bloc Québécois took fewer than the 28,243-vote margin.

No poll ended in a tie.
Flip the seatHypothetical
It would have taken 14,122 voters switching from Liberal to Conservative — 22.0% of the 64,242 valid votes, 21.9 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 28,243 votes. Actual margin: 28,243.
IVElection day versus advance
Only 49.0% 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.
