The Liberals were first at five of the eight general elections from 2004 to 2025, the Conservatives at three; it changed hands twice. In 2025 the Liberals took 56.1% of the vote here, 19.9 points above their average of 36.2% at the seven general elections from 2004 to 2021. It has gone with the party that formed the government at all eleven general elections from 1993 to 2025.

On today's boundaries the Liberals were first here in 2004 (37.9%), 2015 (47.5%), 2019 (46.4%), 2021 (44.0%) and 2025 (56.1%) and the Conservatives in 2006 (33.8%), 2008 (39.6%) and 2011 (43.9%), 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 2006 the carried top two are within two points, so which party was first is less certain.

Before 2025
  • 2021 Liberal · Filomena Tassi, by 9,683 votes (15.4 pts)
  • 2019 Liberal · Filomena Tassi, by 12,874 votes (19.9 pts)
  • 2015 Liberal · Filomena Tassi, by 9,873 votes (15.9 pts)
