Châteauguay

Châteauguay is a town in the Roussillon region of southwestern Quebec, situated where the Châteauguay River meets the St. Lawrence River. The community spans across both riverbanks and features residential neighborhoods mixed with green spaces and waterfront areas.

The Battle of Châteauguay in 1813 was a crucial moment when British forces under Colonel Charles de Salaberry stopped an American advance toward Montreal. The area had started as a land grant to Charles Lemoyne during New France before passing to other owners over time.

The municipality maintains a dual linguistic character, with French spoken by 56 percent of residents and English by 29 percent of the population.

Bus routes connect the area to central Montreal and are spread throughout neighborhoods for convenient access. Visitors arriving from outside should plan travel time to reach the town center or explore different parts of the community.

Marguerite d'Youville, a woman who was later canonized, purchased the land in the late 1700s and established Saint-Joachim Church at the location. This acquisition marked the start of a spiritual and cultural direction that shaped the community.
