Since 2021

Against the 2021 result on these boundaries, the Conservatives are up 5.7 (55.4% to 61.1%), the Liberals up 17.6 (15.1% to 32.7%), the New Democrats down 15.6 (19.2% to 3.6%) and the others up 0.2 (1.0% to 1.2%), 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: a Conservative stronghold

Each election carried onto today's boundaries by where the riding's 2025 electors lived: our estimate to 2019, Elections Canada's transposition for 2021, the official result for 2025. Parties are counted as they ran.

The Conservatives were first here at all eight general elections from 2004 to 2025, by an average of 41.1 points over the next party. In 2025 the Conservatives took 61.1% of the vote here, 0.5 points below their average of 61.6% at the seven general elections from 2004 to 2021.

On today's boundaries the Conservatives were first here in 2004 (62.6%), 2006 (67.3%), 2008 (67.0%), 2011 (56.5%), 2015 (56.8%), 2019 (65.8%), 2021 (55.4%) and 2025 (61.1%), 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.

IDid this riding change?

Essentially no. Today's Lethbridge covers almost exactly the same ground as the Lethbridge riding it replaced, and 100% of its 2025 electors lived in it.

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.

The 2021 column is Elections Canada's official transposition of the 2021 result onto these 2023 boundaries. ± is the change in each party's share. It is not "swing": with four or more competitive parties there is no single pair to swing between.

Third place vs. the margin

New Democratic took fewer than the 18,967-vote margin.

Flip the seatHypothetical

It would have taken 9,484 voters switching from Conservative to Liberal — 14.2% of the 66,937 valid votes, 14.2 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Conservative by 18,967 votes. Actual margin: 18,967.

IVElection day versus advance

Only 53.4% of this riding's votes were cast at election-day polls. The rest were advance or special ballots.

On election day the Conservatives took 62.9%, the Liberals 29.9%, the New Democrats 4.1% and the others 1.5%; in advance and special ballots, 58.9%, 36.0%, 3.1% and 0.9%, in that order.

An association, not a cause. Voters who cast ballots before election day differed from those who turned out on the day. It does not say why. There is no poll-level turnout figure on this page: the elector count on a polling division includes people who voted in advance and were counted elsewhere.
