CBC News projects Liberal Stéphane Lauzon will once again win in Argenteuil-La Petite-Nation, the Ottawa-Gatineau region's easternmost riding.

A former paper company worker, teacher and Gatineau city councillor, Lauzon has now pulled off four straight wins here, recently holding off the Bloc Québécois in tight 2019 and 2021 races.

The riding boundaries were significantly different before that.

His constituency currently runs along the Ottawa River from Gatineau through Grenville-sur-la-Rouge, Montebello and Thurso to Lachute, going as far north as Val-des-Bois and Duhamel.

The riding gained territory on its western flank, moving Val-des-Monts from Pontiac-Kitigan Zibi and bringing a couple of areas over from the riding of Gatineau.

It also lost seven eastern communities to the new riding of Les Pays-d'en-Haut.

Six candidates ran here this time. Conservative Martin Charron came second.
