AI Analysis: Canada Mortgage and Housing Corporation, housing under construction in all centres 10,000 and over for Canada, provinces and selected census metropolitan areas

Executive Summary

Canada's housing construction activity has grown dramatically over six decades, reaching an all-time record of 362,752 units under construction in October 2022 — a level so elevated it was flagged as a statistical outlier relative to the full historical range. The data spans 20 regions from 1962 to 2026, revealing a heavily right-skewed distribution where a handful of large provinces and metropolitan areas, particularly Ontario, Quebec, and British Columbia, dominate national construction volumes. A sharp acceleration in activity beginning around 2015–2016 and continuing through the pandemic era marks a structural shift in Canadian housing construction unlike anything seen in the prior 50 years of data.

Key Findings

• Canada's housing under construction peaked at an all-time high of 362,752 units in October 2022, well above the IQR-based statistical outlier threshold of 293,139 units, with 7 outlier observations all concentrated in the post-2020 period.
• The historical low point was 45,301 units in January 1996, reflecting a prolonged mid-1990s housing slump — meaning construction volumes have grown by roughly 8x from trough to peak over the dataset's history.
• The data is heavily right-skewed, with a mean of 18,772 units nearly three times the median of 6,360 units, driven by large national and provincial aggregates pulling the average upward.
• Ontario and British Columbia are the largest provincial contributors to national construction volumes, while Toronto, Vancouver, and Montreal lead among census metropolitan areas.
• The middle 50% of all regional observations fall between just 1,698 and 19,720 units, confirming that most individual regions maintain comparatively modest construction activity relative to the national total.
• Alberta recorded the most extreme single year-over-year swing in the entire dataset at +299.8% in April 1969, and every major region analyzed experienced year-over-year swings exceeding ±50% at least once across the 64-year history.
• A strong positive correlation exists across most Canadian regions, suggesting that national housing cycles drive construction activity broadly and simultaneously, though some regional divergence is present.
