In Argenteuil—La Petite-Nation on the 2013 boundaries, the riding most of the 2025 electors in today's Argenteuil—Papineau—Des Collines lived in; Elections Canada's official results. The elections from 2004, carried onto today's lines, are below.
No party has held it since 2004: the Liberals were first at four of the eight general elections from 2004 to 2025, the Bloc Québécois at three and the NDP at one; it changed hands twice. In 2025 the Liberals took 47.5% of the vote here, 17.6 points above their average of 29.9% at the seven general elections from 2004 to 2021.
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.
