Since 2021

Against the 2021 result on these boundaries, the Conservatives are up 4.8 (48.2% to 53.0%), the Liberals up 16.3 (24.5% to 40.8%), the New Democrats down 12.6 (17.1% to 4.5%) and the People's Party down 7.9 (9.6% to 1.7%), in points of the valid votes.

2021 is Elections Canada's transposition of that election onto the 2023 boundaries, not an election held on these lines.

The Conservatives were first here at all eight general elections from 2004 to 2025, by an average of 18.4 points over the next party, short of the 20 a stronghold needs. In 2025 the Conservatives took 53.0% of the vote here, 6.1 points above their average of 46.9% at the seven general elections from 2004 to 2021.

On today's boundaries the Conservatives were first here in 2004 (42.0%), 2006 (46.1%), 2008 (48.1%), 2011 (54.5%), 2015 (42.9%), 2019 (46.3%), 2021 (48.2%) and 2025 (53.0%), each with the share of the valid votes shown.

A stronghold is a party first at every general election since 2004, by an average of 20 points or more over the next party; held, first at every one; usually, first at all but one. By-elections are not counted. By this rule 23 of the 343 ridings are held without being strongholds. The results before 2021 are carried onto today's boundaries by where the riding's 2025 electors lived: our estimate, from the older boundaries of Taylor, Lucas, Kirby and Hewitt and the results in Sevi's "Who Runs?". 2021 is Elections Canada's transposition, and 2025 the official result.

Before 2025

IDid this riding change?

Essentially no. Today's Perth—Wellington covers almost exactly the same ground as the Perth—Wellington riding it replaced, and 100% of its 2025 electors lived in it.

How this is measured. Electors: the share of the current riding's 2025 ordinary-list electors who lived in each former riding, each 2025 polling division placed in the 2013 riding a point inside it falls in. Area: the share of the current riding's area that came from each former riding, by intersecting the 2013 and 2023 boundary files, and how much of the former riding that part was. Area is land, not population. Elections Canada counts 48 of 343 ridings as entirely unchanged.

IIThe 2025 result

Candidate	Party	Votes	%	2021	±
John Nater	Conservative	33,972	53.0%	48.2%	+4.8
David Mackey	Liberal	26,142	40.8%	24.5%	+16.3
Kevin Kruchkywich	New Democratic	2,909	4.5%	17.1%	−12.6
Wayne Baker	People's	1,069	1.7%	9.6%	−7.9

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

Third place vs. the margin

New Democratic took fewer than the 7,830-vote margin.

Flip the seatHypothetical

It would have taken 3,916 voters switching from Conservative to Liberal — 6.1% of the 64,092 valid votes, 6.1 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Voters who switch: 007,832

Conservative33,972

Still Conservative by 7,830 votes. Actual margin: 7,830.

IVElection day versus advance

Only 52.4% of this riding's votes were cast at election-day polls. The rest were advance or special ballots.

On election day the Liberals took 34.5%, the Conservatives 58.3%, the New Democrats 5.2% and the People's Party 2.0%; in advance and special ballots, 47.7%, 47.2%, 3.9% and 1.2%, in that order.

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.
