Since 2021

Against the 2021 result on these boundaries, the Liberals are up 0.6 (58.3% to 58.9%), the Conservatives up 10.2 (18.0% to 28.2%), the Bloc Québécois down 2.1 (7.8% to 5.7%), the New Democrats down 6.1 (10.6% to 4.5%) and the Greens up 1.5 (0.1% to 1.6%), in points of the valid votes.

2021 is Elections Canada's transposition of that election onto the 2023 boundaries, not an election held on these lines.

The Liberals were first here at all eight general elections from 2004 to 2025, by an average of 37.5 points over the next party. In 2025 the Liberals took 58.9% of the vote here, 1.2 points above their average of 57.7% at the seven general elections from 2004 to 2021. The Liberals have been first here at every general election since 1988, twelve in a row.

On today's boundaries the Liberals were first here in 2004 (65.3%), 2006 (58.4%), 2008 (60.2%), 2011 (42.4%), 2015 (60.7%), 2019 (58.2%), 2021 (58.3%) and 2025 (58.9%), 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 77 of the 343 ridings are strongholds. 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 · Emmanuella Lambropoulos, by 15,154 votes (40.6 pts)
  • 2019 Liberal · Emmanuella Lambropoulos, by 16,522 votes (41.2 pts)
  • 2015 Liberal · Stéphane Dion, by 16,965 votes (42.1 pts)

In the old Saint-Laurent on the 2013 boundaries, the riding most of the 2025 electors in today's Saint-Laurent lived in; Elections Canada's official results.

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.
