Since 2021

Against the 2021 result on these boundaries, the Liberals are up 9.7 (37.7% to 47.4%), the Conservatives up 13.1 (29.9% to 43.0%) and the New Democrats down 20.0 (27.4% to 7.4%), 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 at four of the eight general elections from 2004 to 2025, the Liberals at four; it changed hands once. In 2025 the Liberals took 47.4% of the vote here, 20.9 points above their average of 26.5% at the seven general elections from 2004 to 2021.

On today's boundaries the Conservatives were first here in 2004 (40.9%), 2006 (41.1%), 2008 (54.6%) and 2011 (56.1%) and the Liberals in 2015 (35.3%), 2019 (34.7%), 2021 (37.7%) and 2025 (47.4%), 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 2019 the carried top two are within two points, so which party was first is less certain.

IDid this riding change?

Yes — it shrank. All of today's Coquitlam—Port Coquitlam, its electors as well as its ground, comes from the old Coquitlam—Port Coquitlam, but it is only 97% 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

4,253 votes

New Democratic took more than the 2,520-vote margin. True in 100 of 343 ridings in 2025.

Flip the seatHypothetical

It would have taken 1,261 voters switching from Liberal to Conservative — 2.2% of the 57,522 valid votes, 2.2 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Voters who switch: 002,522

Still Liberal by 2,520 votes. Actual margin: 2,520.

IVElection day versus advance

Only 48.2% of this riding's votes were cast at election-day polls. The rest were advance or special ballots. On election day alone, the Conservatives led here — the seat was decided by ballots cast before the day.

On election day the Liberals took 42.7%, the Conservatives 46.4%, the New Democrats 8.3%, the others 1.7% and the Greens 1.0%; in advance and special ballots, 51.7%, 39.8%, 6.6%, 1.1% and 0.8%, 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.
