Vaudreuil

Vaudreuil is a suburban riding west of Montreal in the Monteregie region, encompassing the cities of Vaudreuil-Dorion, L'Ile-Perrot, Notre-Dame-de-l'Ile-Perrot, Pincourt, Hudson, Saint-Lazare, Rigaud, and several smaller municipalities. The riding was reconfigured during the 2022 redistribution, which separated the former Vaudreuil--Soulanges riding and transferred the Soulanges municipalities to the neighbouring Salaberry--Suroit--Soulanges district. The population exceeds the provincial average, and the riding is one of the most bilingual in Quebec, with significant anglophone minorities in Hudson and other western communities alongside a francophone majority.

About the Riding

Vaudreuil-Dorion, the riding's largest city, has been one of the fastest-growing municipalities in greater Montreal, driven by families seeking affordable suburban homes within commuting distance of the island. The construction of new residential subdivisions has placed pressure on local infrastructure, schools, and healthcare services. Saint-Lazare and Hudson offer a more rural, equestrian-friendly character, while Rigaud anchors the riding's western edge near the Ontario border.

In 2025, the riding's federal issues centred on housing affordability in a market where rapid population growth has strained supply, the adequacy of highway and public transit infrastructure -- particularly the chronic congestion on autoroute 20 and the Ile-aux-Tourtes Bridge corridor -- and the cost of living for commuter families. The riding's bilingual character meant that language politics and the federal Official Languages Act were sensitive topics. US tariff threats weighed on workers connected to the broader Montreal-area manufacturing economy, while agricultural communities in the riding's rural western sections raised concerns about trade protections for supply-managed farms.
