2021 Canadian census was a detailed enumeration of the population conducted by the national statistical agency. It marked the first census cycle where the majority of responses were collected online, reflecting a significant modernization in data gathering techniques. The results provided a crucial snapshot of the nation's demographic, social, and economic characteristics following a period impacted by the COVID-19 pandemic in Canada.

Background and purpose

The census is a cornerstone of national statistics, mandated by the Constitution Act, 1867 and the Statistics Act. Conducted every five years, it fulfills constitutional requirements for determining representation in Parliament and the allocation of federal transfer payments to provinces and territories. The data underpins critical policy decisions by institutions like the Department of Finance Canada and informs planning for services ranging from health care to transportation infrastructure. Previous cycles, such as the 2016 Canadian census, set important precedents for methodology and question content that the 2021 iteration built upon.

Data collection and methodology

Primary data collection occurred on May 11, 2021, with the long-form census being distributed to one in four households. A major innovation was the emphasis on digital-first collection, managed through secure online portals administered by Statistics Canada. Field operations involved thousands of enumerators across regions like Atlantic Canada and the Prairie provinces to follow up with non-respondents and reach populations in remote areas, including First Nations reserves and communities in the Yukon. The agency employed advanced data validation and imputation techniques to ensure quality and completeness, while maintaining strict confidentiality protocols aligned with the Privacy Act.

Key findings and population changes

The enumerated population was 36,991,981, representing a growth of 5.2% from the 2016 Canadian census. This was the lowest intercensal growth rate since the 1941 census, a slowdown attributed in part to the COVID-19 pandemic in Canada. Ontario remained the most populous province, while Prince Edward Island recorded the highest growth rate among the provinces. For the first time, the census reported over one million people identifying as Indigenous. The data also showed a continuing trend of population concentration in major metropolitan areas such as the Greater Toronto Area, Metro Vancouver, and the Communauté métropolitaine de Montréal.

Geographic and demographic details

The census provided detailed geographic breakdowns, from the national level down to census subdivisions and dissemination areas. It recorded significant demographic shifts, including an aging population, with more people over 65 than under 15 for the first time. Immigration continued to be a primary driver of growth, with top source countries including the Philippines, India, and the People's Republic of China. Linguistic data showed increases in speakers of non-official languages, while the proportion of people reporting French as a first language declined outside of Quebec and New Brunswick.

Data release and accessibility

Statistics Canada began a phased release of data starting in February 2022. Key datasets were made available through the agency's website and data visualization tools, including the Census Profile and Census Program Data Viewer. Aggregate data was also disseminated to partners like the United Nations and research institutions such as the University of Toronto. To protect privacy, detailed information for small geographic areas or populations was suppressed or randomized, adhering to policies established after the Second World War.

Impact and uses of census data

The findings immediately influenced the federal electoral redistribution process, overseen by bodies like Elections Canada. Provincial governments, including the Government of Alberta and the Government of Quebec, use the data for resource allocation and program planning. Municipalities like the City of Calgary and the City of Winnipeg rely on it for urban planning and service delivery. Beyond government, the data is vital for academic research, business market analysis by firms like Ipsos, and advocacy work by organizations such as the Assembly of First Nations and the Fédération des communautés francophones et acadienne du Canada.
