What this data can and can’t tell you
- What these tables don’t give. For origins the charts stop at visible minority and Indigenous identity, and the Census Profile has nothing on unpaid care, cars or the internet, or on change by age since 2016.
- 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. A figure here is set beside two middles, the median across Quebec’s places of 2,500 people or more and the median across all Canadian towns that size; reserves and entire cities are excluded from both.
