Adapted from Statistics Canada, Population estimates on July 1, by age and gender, 2025-09-24. This does not constitute an endorsement by Statistics Canada of this product.

How this answer was calculatedThe headline compares the first and last observations shown. Absolute change is the last source value minus the first; relative change is (last ÷ first − 1) × 100. Intermediate observations remain visible in the chart and exact values. This is descriptive and does not identify causes.
