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 54.2% of the vote here, 7.2 points above their average of 47.0% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (53.0%), 2006 (49.6%), 2008 (44.6%), 2015 (49.5%), 2019 (49.9%), 2021 (47.9%) and 2025 (54.2%) and the Conservatives in 2011 (44.0%), 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 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 · Jennifer O'Connell, by 6,295 votes (10.8 pts)
  • 2019 Liberal · Jennifer O'Connell, by 13,925 votes (21.9 pts)
  • 2015 Liberal · Jennifer O'Connell, by 7,166 votes (12.1 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.
