The Liberal party has maintained a hold on the riding of Argenteuil-La Petite Nation. 

In Monday’s federal election, Liberal incumbent Stéphane Lauzon was re-elected with 18,064 votes and 37.7 per cent of the popular vote. Bloc Québécois candidate Yves Destroismaisons followed with 16,975 votes and 35.4 per cent of the popular vote. Marie Louis-Seize, the Conservative candidate finished third with 6,213 votes and 13 per cent of the popular vote. Results were current as of 1:08 a.m. Tuesday. 

New Democratic Party (NDP) candidate Michel Welt received 3,253 votes and 6.8 per cent of the popular vote, followed by Marc Vachon of the People’s Party of Canada (PPC) who received 2,701 votes and 5.6 per cent of the popular vote. Free Party candidate Paul Lynes received 719 votes and 1.5 per cent of the popular vote. 

Lauzon was first elected as the Member of Parliament (MP) for Argenteuil-La Petite Nation in 2015 and was narrowly re-elected in 2019 over Destroismaisons, who was also the Bloc Quebecois candidate in that election. The 2021 federal election was also the second attempt at federal office for Louis-Seize, who had also been the Conservative candidate in 2019. 

During the 2021 campaign, Lauzon heavily emphasized his record on securing infrastructure and high-speed internet funding for the riding.
