IDid this riding change?

Yes — it shrank. All of today's Simcoe North comes from the old Simcoe North, but it is only 90% 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
1.9 pts
Half the margin: the share that would have had to move from first to second.
Third place vs. the margin
2,508 votes
New Democratic took more than the 2,474-vote margin. True in 100 of 343 ridings in 2025.

Flip the seatHypothetical

It would have taken 1,238 voters switching from Conservative to Liberal — 1.9% of the 66,605 valid votes, 1.9 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

IVElection day versus advance

Only 55.7% 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.
