District at a glance
2021 Census of Population. Statistics Canada publishes no profile on Ontario's provincial districts, but the 111 southern ones share their lines with the 2013 federal ridings, so their figures are the census's own for those ridings. The 13 northern districts are built from the dissemination areas inside each one: counts are sums, medians are estimates. Ranks are against all 124 districts.
