Since 2021

Against the 2021 result on these boundaries, the Liberals are up 13.3 (49.7% to 63.0%), the Conservatives up 8.8 (22.4% to 31.2%), the New Democrats down 13.0 (16.7% to 3.7%) and the Greens down 2.1 (4.2% to 2.1%), 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 Liberals were first here at seven of the eight general elections from 2004 to 2025; the Conservatives were first in 2011. In 2025 the Liberals took 63.0% of the vote here, 16.2 points above their average of 46.8% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (59.2%), 2006 (47.7%), 2008 (39.2%), 2015 (57.7%), 2019 (42.9%), 2021 (49.7%) and 2025 (63.0%) and the Conservatives in 2011 (35.7%), 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 83 of the 343 ridings are usually one party's. 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.

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	±
Ginette Petitpas Taylor	Liberal	30,215	63.0%	49.7%	+13.3
Jocelyn Dionne	Conservative	14,974	31.2%	22.4%	+8.8
Serge Landry	New Democratic	1,775	3.7%	16.7%	−13.0
Marshall Dunn	Green	994	2.1%	4.2%	−2.1

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 7,621 voters switching from Liberal to Conservative — 15.9% of the 47,958 valid votes, 15.9 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 15,241 votes. Actual margin: 15,241.

On election day the Liberals took 55.8%, the Conservatives 36.7%, the New Democrats 4.6% and the Greens 2.9%; in advance and special ballots, 68.5%, 27.0%, 3.0% and 1.4%, 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.
