Since 2021

Against the 2021 result on these boundaries, the Liberals are up 9.5 (42.3% to 51.8%), the Conservatives up 9.9 (33.3% to 43.2%) and the New Democrats down 13.9 (18.3% to 4.4%), 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.

Since 2004: no party has held it

Each election carried onto today's boundaries by where the riding's 2025 electors lived: our estimate to 2019, Elections Canada's transposition for 2021, the official result for 2025. Parties are counted as they ran.

The Conservatives were first at four of the eight general elections from 2004 to 2025, the Liberals at four; it changed hands once. In 2025 the Liberals took 51.8% of the vote here, 15.7 points above their average of 36.1% at the seven general elections from 2004 to 2021.

On today's boundaries the Conservatives were first here in 2004 (38.9%), 2006 (39.1%), 2008 (42.7%) and 2011 (42.2%) and the Liberals in 2015 (49.3%), 2019 (41.3%), 2021 (42.3%) and 2025 (51.8%), 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 160 of the 343 ridings have no degree. 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.

IIIHow close was it, really

Third place vs. the margin

New Democratic took fewer than the 5,488-vote margin.

Flip the seatHypothetical

It would have taken 2,745 voters switching from Liberal to Conservative — 4.3% of the 63,293 valid votes, 4.3 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 5,488 votes. Actual margin: 5,488.

IVElection day versus advance

Only 48.2% of this riding's votes were cast at election-day polls. The rest were advance or special ballots.

On election day the Liberals took 48.6%, the Conservatives 45.6% and the New Democrats 5.2%; in advance and special ballots, 54.9%, 40.9% and 3.7%, 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.
