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 50.2% of the vote here, 0.4 points below their average of 50.6% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (56.8%), 2006 (52.2%), 2008 (49.6%), 2015 (54.3%), 2019 (53.5%), 2021 (49.8%) and 2025 (50.2%) and the Conservatives in 2011 (41.1%), 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.

Before 2025

2021 Liberal · Peter Fonseca, by 8,084 votes (17.7 pts)
2019 Liberal · Peter Fonseca, by 10,259 votes (19.5 pts)
2015 Liberal · Peter Fonseca, by 9,801 votes (18.8 pts)

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.
