IDid this riding change?

Essentially no. Today's Longueuil—Charles-LeMoyne covers almost exactly the same ground as the Longueuil—Charles-LeMoyne 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.

Flip the seatHypothetical

It would have taken 5,778 voters switching from Liberal to Bloc Québécois — 11.4% of the 50,900 valid votes, 11.3 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.

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.
