Since 2021

Against the 2021 result on these boundaries, the Liberals are up 5.9 (56.7% to 62.6%), the Conservatives up 3.6 (29.6% to 33.2%), the New Democrats down 6.7 (9.1% to 2.4%) and the Greens unchanged (1.1% to 1.1%), 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.

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 first two are within two points, so which party was first is less certain.

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 62.6% of the vote here, 10.0 points above their average of 52.6% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (59.4%), 2006 (53.3%), 2008 (44.8%), 2015 (55.3%), 2019 (57.3%), 2021 (56.7%) and 2025 (62.6%) and the Conservatives in 2011 (42.2%), 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. In 2011 the carried top two are within two points, so which party was first is less certain.

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.

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.
