What this data can and can’t tell you
- The census’s own words. In the census, “visible minority” is the Employment Equity Act’s term for people who are non-white in colour or race and not Indigenous. Like immigrant status, Indigenous identity and religion, which residents reported themselves, it is compared with other towns, never turned into a label.
- Against Ontario’s towns and Canada’s towns. Two medians frame each figure: one for Ontario’s towns and neighbourhoods of 2,500 or more, one for all Canadian towns of that size, with whole cities and First Nations reserves left out. Percentiles rank the town within Canada.
- What these tables don’t give. The Census Profile has no unpaid care, cars or internet access, and no change by age since 2016; ethnic origins beyond visible minority and Indigenous identity aren’t charted here.
