Methodology

Data vintage: Reference date was Census Day, May 11, 2021. Statistics Canada released this profile in stages starting February 9, 2022, with later characteristics added through the remainder of 2022.
Rounding & suppression: To protect respondent confidentiality, Statistics Canada randomly rounds every count shown here, and withholds some characteristics entirely for areas with very small populations. This is why a small number of figures on this page may show as unavailable for smaller places — it reflects a StatCan privacy rule, not missing data on our end.
Next update: These are the most recent figures available. Canada's next census is scheduled for May 2026, with results expected to begin release in 2027.

Statistics Canada (statcan.gc.ca) conducted the 2026 Census of Population in May 2026. However, census data goes through an extensive processing, validation, and quality-assurance period before public release. Based on the release plan, the 2026 Census results begin rolling out on February 10, 2027, with complete community-level profiles available by December 1, 2027. Until then, this page uses 2021 Census data as its primary source, supplemented by a population projection estimate for 2026 calculated using the compound annual growth rate (CAGR) from the 2016–2021 Census period.
