Montmagny grades low on several counts. Prices are high against local incomes: at the median price, a 70 m² home costs 7.6 times the median annual income per consumption unit in the intercommunality. Its strongest is walkability (A+) — 100% of residents live within 800 m of a bakery, and 51% of working residents walk, cycle or take public transport to work.
