Since 2021

Against the 2021 result on these boundaries, the Liberals are up 11.2 (49.3% to 60.5%), the Conservatives up 8.2 (10.9% to 19.1%), the Bloc Québécois down 6.8 (23.1% to 16.3%) and the New Democrats down 5.7 (8.5% to 2.8%), 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.

Since 2004: no party has held it

The Liberals were first at five of the eight general elections from 2004 to 2025, the Bloc Québécois at two and the NDP at one; it changed hands three times. In 2025 the Liberals took 60.5% of the vote here, 22.3 points above their average of 38.2% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (42.1%), 2015 (53.9%), 2019 (51.8%), 2021 (49.3%) and 2025 (60.5%), the Bloc Québécois in 2006 (39.3%) and 2008 (29.2%) and the NDP in 2011 (61.8%), 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 2004 the carried top two are within two points, so which party was first is less certain.

Before 2025
  • 2021 Liberal · Steven MacKinnon, by 13,989 votes (26.6 pts)
  • 2019 Liberal · Steven MacKinnon, by 17,158 votes (30.7 pts)
  • 2015 Liberal · Steven MacKinnon, by 15,724 votes (27.2 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.

It would have taken 11,885 voters switching from Liberal to Conservative — 20.7% of the 57,399 valid votes, 20.7 points — to change the result. No ballot was cast this way; this only moves votes between the top two.
