The Liberals were first at four of the eight general elections from 2004 to 2025, the Conservatives at three and the Greens at one; it changed hands four times. In 2025 the Conservatives took 34.2% of the vote here, 3.2 points above their average of 31.0% at the seven general elections from 2004 to 2021.
On today's boundaries the Liberals were first here in 2004 (47.3%), 2006 (44.0%), 2015 (48.8%) and 2019 (37.3%), the Conservatives in 2008 (36.6%), 2011 (42.1%) and 2025 (34.2%) and the Greens in 2021 (33.0%), 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. In 2008 the carried top two are within two points, so which party was first is less certain.
