Statistics Canada conducts a country-wide census that collects demographic data every five years on the first and sixth year of each decade. The 2021 Canadian census enumerated a total population of 36,991,981, an increase of around 5.2 percent over the 2016 figure. It is estimated that Canada's population surpassed 40 million in 2023 and 41 million in 2024. Between 1990 and 2008, the population increased by 5.6 million, equivalent to 20.4 percent overall growth. The main driver of population growth is immigration, with 6.2% of the country's population being made up of temporary residents as of 2023, or about 2.5 million people. Between 2011 and May 2016, Canada's population grew by 1.7 million people, with immigrants accounting for two-thirds of the increase.
The 2000 United States census, conducted by the Census Bureau, determined the resident population of the United States on April 1, 2000, to be 281,421,906, an increase of 13.2 percent over the 248,709,873 people enumerated during the 1990 census. This was the twenty-second federal census and was at the time the largest civilly administered peacetime effort in the United States.
Canada ranks 36th by population among countries of the world, comprising about 0.5% of the world's total, with more than 40 million Canadians as of 2024. Despite being the second-largest country by total area, the vast majority of the country is sparsely inhabited, with most of its population south of the 55th parallel north. Just over 60 percent of Canadians live in just two provinces: Ontario and Quebec. Though Canada's overall population density is low, many regions in the south, such as the Quebec City–Windsor Corridor, have population densities higher than several European countries. Canada has six population centres with more than one million people: Toronto, Montreal, Vancouver, Calgary, Edmonton and Ottawa.
According to the 2021 Canadian census, over 450 "ethnic or cultural origins" were self-reported by Canadians.

The 2011 Canadian census was a detailed enumeration of the Canadian population on May 10, 2011. Statistics Canada, an agency of the Canadian government, conducts a nationwide census every five years. In 2011, it consisted of a mandatory short form census questionnaire and an inaugural National Household Survey (NHS), a voluntary survey which replaced the mandatory long form census questionnaire; this substitution was the focus of much controversy. Completion of the census is mandatory for all Canadians, and those who do not complete it may face penalties ranging from fines to prison sentences.
Ontario, one of the 13 provinces and territories of Canada, is located in east-central Canada. It is Canada's most populous province by a large margin, accounting for nearly 40 percent of all Canadians, and is the second-largest province in total area. Ontario is fourth-largest in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto.
Prince Edward Island is a Canadian province. According to the 2011 National Household Survey, the largest ethnic group consists of people of Scottish descent (39.2%), followed by English (31.1%), Irish (30.4%), French (21.1%), German (5.2%), and Dutch (3.1%) descent. Prince Edward Island is mostly a white community and there are few visible minorities. Chinese people are the largest visible minority group of Prince Edward Island, comprising 1.3% of the province's population. Almost half of respondents identified their ethnicity as "Canadian." Prince Edward Island is by a strong margin the most Celtic and specifically the most Scottish province in Canada and perhaps the most Scottish place (ethnically) in the world, outside Scotland. 38% of islanders claim Scottish ancestry, but this is an underestimate and it is thought that almost 50% of islanders have Scottish roots. When combined with Irish and Welsh, almost 80% of islanders are of some Celtic stock, albeit most families have resided in PEI for at least two centuries. Few places outside Europe can claim such a homogeneous Celtic ethnic background. The only other jurisdiction in North America with such a high percentage of British Isles heritage is Newfoundland.
