IDid this riding change?
Essentially no. Today's Oshawa covers almost exactly the same ground as the Oshawa 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

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

Flip the seatHypothetical
It would have taken 1,740 voters switching from Conservative to Liberal — 2.6% of the 66,700 valid votes, 2.6 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.
