What this data can and can’t tell you
- The census’s own words. “Visible minority” is the census’s term from the Employment Equity Act: people, other than Indigenous peoples, who are non-white in colour or race. Indigenous identity, immigrant status and religion are as residents answered. The page compares them with other towns and never labels a town by them.
- Against Quebec’s towns and Canada’s towns. Provincial and national yardsticks: Quebec’s towns and neighbourhoods of at least 2,500 residents, and all Canadian towns of that size. No whole city and no First Nations reserve is in either median.
- What these tables don’t give. Missing from the census as published: unpaid care, cars and internet access, and the shift in each age band since 2016. Ethnic origins past visible minority and Indigenous identity aren’t charted here.
