IDid this riding change?
Yes — it shrank. All of today's Terrebonne comes from the old Terrebonne, but it is only 98% of that riding. The rest went elsewhere.

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
<0.1 pts
The margin was 1 vote of 60,278.
Third place vs. the margin
10,961 votes
Conservative took more than the 1-vote margin. True in 100 of 343 ridings in 2025.

1 poll ended in an exact tie.
Flip the seatHypothetical
It would have taken 1 voter switching from Liberal to Bloc Québécois — 0.00% of the 60,278 valid votes, under 0.1 points — to change the result. No ballot was cast this way; this only moves votes between the top two.
Liberal23,352
Bloc Québécois23,351
Still Liberal by 1 vote. Actual margin: 1.
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.
