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. These are self-reported answers: Indigenous identity, immigrant status, religion. The census’s “visible minority” comes from the Employment Equity Act (non-white in colour or race, Indigenous peoples aside), and the page sets each beside other towns without labelling any.
- 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.
