Against the 2021 result on these boundaries, the Conservatives are up 8.9 (58.9% to 67.8%), the Liberals up 9.5 (12.7% to 22.2%), the New Democrats down 7.1 (14.4% to 7.3%), the People's Party down 9.2 (10.5% to 1.3%) and the Greens down 0.8 (2.1% to 1.3%), 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 Conservatives were first here at all eight general elections from 2004 to 2025, by an average of 39.8 points over the next party. In 2025 the Conservatives took 67.8% of the vote here, 9.2 points above their average of 58.6% at the seven general elections from 2004 to 2021.

On today's boundaries the Conservatives were first here in 2004 (54.7%), 2006 (59.5%), 2008 (61.5%), 2011 (64.1%), 2015 (46.7%), 2019 (64.5%), 2021 (58.9%) and 2025 (67.8%), 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 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 Conservative · Dan Mazier, by 17,040 votes (44.3 pts)
  • 2019 Conservative · Dan Mazier, by 20,379 votes (50.2 pts)
  • 2015 Conservative · Robert Sopuck, by 7,000 votes (16.8 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.
