Ontario population growth
Some data is also available from before the official Canadian census began, showing that the population of Ontario grew from 150,066 people in 1924 to 213,156 in 1830, just six years later. A further ten years to 1840 and the number of people living in Ontario had almost doubled to 1840.
By the time of the first official census in 1851, the population had more than doubled again, to a staggering 952,004 people. It was at this point that Ontario overtook Quebec as the largest province in Canada, a position that it has never lost.
The population of Ontario has increased at every census since then, always closely followed by Quebec.
From then on, population increases of between 10% and 20% every ten years were common, sometimes pushing as high as 35% – for example in the baby boom years of the 1950s.
Over the past ten years, average ten yearly population increases have dipped just below 10% for the first time.
The table below lists the population of Ontario at the point of each census since 1851. Between 1851 and 1951 the census was held every ten years, since then it has been held every five years. The most recent census was in 2021.

Where is Ontario?
Ontario is in the centre and east of Canada. It has boundaries with Quebec in the east, Manitoba in the west, and the Hudson Bay in the north.
To the south of Ontario is the United States. In fact, the province has 2,700km of borders with five US states – Michigan, Minnesota, New York, Ohio and Pennsylvania. The St Lawrence River and the Great Lakes form part of the border between Ontario and the United States.
Ontario is unusual in that one of its census metropolitan areas straddles the border between Ontario and Quebec. Ottawa-Gatineau, also known as the National Capital Region, is split between Ottawa in Ontario and Gatineau in Quebec. It is the only CMA to be part of two Canadian Provinces.
