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 Ontario’s towns and Canada’s towns. Each comparison is its own median: over Ontario’s towns and neighbourhoods of 2,500 or more, and over all Canadian towns of that size (whole cities and First Nations reserves left out). Percentiles are within Canada only.
- 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.
