The Conservatives were first here at seven of the eight general elections from 2004 to 2025; the Liberals were first in 2004. In 2025 the Conservatives took 50.6% of the vote here, 4.0 points above their average of 46.6% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (39.6%) and the Conservatives in 2006 (46.0%), 2008 (51.2%), 2011 (56.8%), 2015 (45.4%), 2019 (41.1%), 2021 (46.5%) and 2025 (50.6%), 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 2004 the carried top two are within two points, so which party was first is less certain.

Before 2025
  • 2021 Conservative · Michael Chong, by 16,873 votes (24.9 pts)
  • 2019 Conservative · Michael Chong, by 13,267 votes (19.0 pts)

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.
