McMasterville is a city nestled in southwestern Quebec, Canada, on the banks of the Richelieu River in La Vallée-du-Richelieu Regional County Municipality. The city was founded in 1917 to accommodate the workers of the Canadian Explosives Limited, which operated until 1998. The town owes its name to William McMaster, the first chairman of the company. As of the 2016 Canadian Census, McMasterville had a population of 5,695 and is part of the Administrative Region of Montérégie.
In September 2023, the Swedish company Northvolt announced plans to construct a 60 GWh/year battery cell factory on the former grounds of the Canadian Explosives Limited factory. This new factory, expected to start production in 2026, will provide employment for approximately 3000 staff. The project is heavily subsidized by Canada, Quebec, and Ottawa, marking a significant step in McMasterville's industrial development.
McMasterville is beautifully located along the Richelieu River, facing Mont St-Hilaire and Otterburn Park. This strategic location offers residents and visitors alike stunning views and a variety of outdoor activities.
Since 2000, McMasterville has been served by the McMasterville commuter rail station on the Réseau de transport métropolitain's Mont-Saint-Hilaire line. Local bus service is also provided by the RTM, making transportation within and outside the city convenient for residents and visitors.
