Is Saint-Denis-sur-Richelieu a good place to live?

Crime is low (A). Health outcomes beat most towns (B+). Owners valued their homes at a median $300,000 in 2021, which is 3.8 years of the typical household’s pay. Hazards are a real consideration (C).

Figures: home values and income: Statistics Canada, Census 2021. Canadian towns get an overall grade from 2,500 residents, so Saint-Denis-sur-Richelieu has subject grades only.

This town's rent is the 2021 census rent scaled to 2025 by its province's ratio of surveyed to census rents: no rental survey covers it, so its Cost Grade is less sure. Safety is the regional police service's figure, shared with its other towns. No School Grade: this province doesn't publish comparable results school by school. Health is graded on the health region's survey figures and life expectancy, with the distance to hospital giving the town its own spread.
