Since 2021

Against the 2021 result on these boundaries, the Liberals are up 10.9 (34.7% to 45.6%), the Bloc Québécois down 7.0 (39.8% to 32.8%), the Conservatives up 7.3 (10.1% to 17.4%), the New Democrats down 5.0 (7.1% to 2.1%) and the Greens down 0.6 (1.8% 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.

The Bloc Québécois were first at five of the eight general elections from 2004 to 2025, the Liberals at two and the NDP at one; it changed hands four times. In 2025 the Liberals took 45.6% of the vote here, 21.4 points above their average of 24.2% at the seven general elections from 2004 to 2021.

On today's boundaries the Bloc Québécois were first here in 2004 (61.0%), 2006 (53.5%), 2008 (45.7%), 2019 (40.6%) and 2021 (39.8%), the NDP in 2011 (49.3%) and the Liberals in 2015 (32.4%) and 2025 (45.6%), 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.

Before 2025
  • 2021 Bloc Québécois · Luc Desilets, by 2,810 votes (5.3 pts)
  • 2019 Bloc Québécois · Luc Desilets, by 2,620 votes (4.5 pts)
  • 2015 Liberal · Linda Lapointe, by 1,676 votes (2.9 pts)

IDid this riding change?

Yes — it shrank. All of today's Rivière-des-Mille-Îles, its electors as well as its ground, comes from the old Rivière-des-Mille-Îles, but it is only 85% of that riding by area. The rest went elsewhere.

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.

IIIHow close was it, really

Third place vs. the margin
10,398 votes
Conservative took more than the 7,657-vote margin. True in 100 of 343 ridings in 2025.
Election-day polls won by others
69 of 216
3 polls ended in an exact tie.

Flip the seatHypothetical

It would have taken 3,829 voters switching from Liberal to Bloc Québécois — 6.4% of the 59,887 valid votes, 6.4 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 7,657 votes. Actual margin: 7,657.

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.
