What the numbers say about Ontario
- Ontario covers 11% of the area of Canada and ranks 1st of 13 by population, against 4th by area.
- It would take 9.23 provinces and territories the size of Ontario to cover Canada.
- Ontario holds 38% of the 37.0 million people that Wikidata’s 2021 figures give for the 13 provinces and territories together: about 1 in 3.
- The largest, Nunavut, is 1.93× the size of Ontario; the smallest, Prince Edward Island, is 0.5% of it.
- Closest in size within Canada: British Columbia (946,000 km², 1.14×) and Northwest Territories (1,348,000 km², 1.25×).
- Counted as a country, Ontario would be larger than 211 of the 239 countries and territories listed on sizeversus, and would rank 29th by area, between Bolivia (1,087,000 km²) and Mauritania (1,036,000 km²).
- With 14.2 million people it would rank 76th of 238 by population.
- Ontario has 13 people per km², about the density of Turkmenistan, which has 13 per km².
- That makes Ontario the 3rd most densely populated of the 13 provinces and territories, 3.55× the average for Canada (3.7 per km²).
- On a standard web map (Web Mercator), a place at 50°N is drawn about 2.4× too large in area, so Ontario looks bigger there than it is.
- Laid out flat, Ontario stretches about 1,690 km north to south and 1,570 km east to west.
- Wikidata's official figure of 1,076,000 km² agrees with our measured area of 1,078,000 km², to within 2%.
