What this data can and can’t tell you
- 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.
- The census’s own words. The census takes “visible minority” from the Employment Equity Act: anyone other than Indigenous peoples who is non-white in colour or race. Indigenous identity, immigrant status and religion are what residents reported, compared here with other towns and never used as a label.
