History

Argenteuil—La Petite-Nation was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order. It came into effect upon the call of the 2015 Canadian federal election.^[4]

It was created out of parts of Argenteuil—Papineau—Mirabel (69%) and Pontiac (31%).^[5]

Following the 2022 Canadian federal electoral redistribution, the riding lost the municipalities of Wentworth-Nord, Lac-des-Seize-Îles, Wentworth, Saint-Adolphe-d'Howard, Morin-Heights, Mille-Isles and Gore to Les Pays-d'en-Haut, and gained Val-des-Monts from Pontiac, and that part of the city of Gatineau north of Autoroute 50 and east of Av. du Cheval-Blanc, and south of a line that follows Rivière Blanche to Highway 148 from the riding of Gatineau.
