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. ## Source and provenance - Official source: [Statistics Canada table 34-10-0126-01]() - Table title: Canada Mortgage and Housing Corporation, housing starts, under construction and completions, all areas, annual - Dataset identifier: 34100126 - Canonical human-readable answer: - Province and territory comparison: - Interpretation policy: this answer describes the selected observations; it does not infer causation. - Source acknowledgement: Adapted from Statistics Canada, Canada Mortgage and Housing Corporation, housing starts, under construction and completions, all areas, annual, 2026-01-21.
