Ottawa Population 2021/2022

Updated: 11/17/21 •  5 min read

The population of Ottawa is 934,243. This makes Ottawa the fourth largest city in Canada, the second largest city in Ontario and the 30th largest city in North America.

Ottawa is the capital city of Canada, located in the province of Ontario right on the border with Québec. Directly across the Ottawa River lies the city of Gatineau whose population in 2016 was 276,245.

Together the two cities make up the National Capital Region of Canada, known as Ottawa-Gatineau.

Latest data from Statistics Canada indicates that the population of the wider Ottawa–Gatineau metro area  is 1.3 million (1,323,783) people – this includes Ottawa, Gatineau and some surrounding areas. This makes it the fifth largest Census Metropolitan area in Canada.

Ottawa is unusual in that it is one of just a few cities in Canada which are officially bilingual. This is partly because it is located on the border between Ontario and Québec and partly because it is the nation’s capital city and attracts people from all around the country.

Ottawa Population Growth

Between 2011 and 2016 Ottawa’s population increased by 5.8%. This is slightly higher than the growth experienced in nearby Toronto.

Population growth in Ottawa is mostly the result of immigration. Around three quarters of new residents in Ottawa are either immigrants from abroad or internal migrants from other parts of Canada. The remaining quarter of Ottawa’s growth is due to natural population increase.
