Châteauguay: Site of a Famous Battle
Châteauguay holds a celebrated place in Canadian history as the site of the Battle of Châteauguay (1813), where a small Canadian force of Voltigeurs under Lieutenant Colonel Charles de Salaberry repelled a much larger American army during the War of 1812 — one of the most significant Canadian military victories of the era. The city grew from a farming community along the Châteauguay River into a major South Shore suburb during the mid-20th century suburbanization of Montreal. Today it is a fully-established city with strong community identity, excellent parks along the river corridor, and convenient access to Montreal via Autoroute 138 and the Samuel-De Champlain Bridge corridor.
