Comparisons between 2016 and 2021 may be affected by boundary changes or differences in 2016 reporting categories. Treat year-over-year deltas as approximate.

To protect confidentiality, Statistics Canada randomly rounds census counts up or down to a multiple of 5 or 10. Totals are rounded independently of their parts, so sub-totals may not match the total and percentages may not add up to 100%. Read more
