Is L'Assomption a good place to live?

Good on most counts; one lags. With an A− overall, L'Assomption is better than just over three quarters of Canadian towns and ranks #219 of 499 in Quebec. Where it does best is safety (A). It also does well on health (B+). Buying in is costly (C). Its other grades sit near the middle: B− for jobs & income and C+ for hazard risk.

Rents here are the metro area's average, shared by every town and neighbourhood in it. 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.
