IDid this riding change?

Essentially no. Today's Pierre-Boucher—Les Patriotes—Verchères covers almost exactly the same ground as the Pierre-Boucher—Les Patriotes—Verchères 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.

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

Conservative took more than the 4,548-vote margin. True in 100 of 343 ridings in 2025.

Flip the seatHypothetical

It would have taken 2,275 voters switching from Bloc Québécois to Liberal — 3.6% of the 62,426 valid votes, 3.6 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Bloc Québécois by 4,548 votes. Actual margin: 4,548.

IVElection day versus advance

Only 60.0% 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.

VWhat kind of place this is

2021 Census, keyed to the 2023 representation order. Comparisons are against the median riding, not Canada as a whole. Each rule places this riding among all 343.
