Since 2021

Against the 2021 result on these boundaries, the Liberals are up 8.9 (53.3% to 62.2%), the Conservatives up 7.1 (11.8% to 18.9%), the Bloc Québécois down 6.4 (19.7% to 13.3%) and the New Democrats down 6.8 (10.3% to 3.5%), 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 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 62.2% of the vote here, 20.5 points above their average of 41.7% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (44.1%), 2015 (50.3%), 2019 (53.9%), 2021 (53.3%) and 2025 (62.2%), the Bloc Québécois in 2006 (38.8%) and 2008 (33.5%) and the NDP in 2011 (41.3%), 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 and 2008 the carried top two are within two points, so which party was first is less certain.

IDid this riding change?

Essentially no. Today's Brossard—Saint-Lambert covers almost exactly the same ground as the Brossard—Saint-Lambert 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.

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.
