AI Analysis: Canada Mortgage and Housing Corporation, housing starts, by type of dwelling unit and market type in all centres of 50,000 and over for Canada and provinces

Executive Summary

Canada's housing starts data (Statistics Canada, Table 34100152) spans nearly 38 years of monthly observations across 11 geographies, revealing a highly skewed construction landscape where 75% of all regional records report 27 or fewer starts per month, yet national totals have reached as high as 12,567 units in a single observation. The data captures distinct boom-bust cycles tied to major economic events — including the late-1980s surge, the early-1990s recession, the 2008 financial crisis, and a post-2020 pandemic-driven spike — with Ontario and British Columbia consistently driving the most extreme values. Apartment and condo construction have emerged as dominant forces, with condo and homeowner market starts showing the strongest correlation (r=0.802), signaling that these two segments increasingly move in tandem.

Key Findings

• The dataset contains 124,575 records with a mean of 192.5 units but a median of 0.0, confirming that the majority of monthly region-type combinations report zero housing starts, reflecting a heavily right-skewed distribution.
• Total housing starts range from 0 to a maximum of 12,567 units in a single monthly observation, with apartment and other units posting the second-highest mean at 211.6 units and a peak of 11,237 — indicating large apartment projects are a primary driver of variability.
• The homeowner market segment leads all market types with a median of 42 units per record, while co-op and 'other' market types show weak correlations (below r=0.40) with all other segments, meaning they behave largely independently.
• Condo and homeowner market starts exhibit the strongest correlation in the dataset (r=0.802), followed by condo and rental starts (r=0.692), suggesting these segments are closely linked in Canada's urban construction cycles.
• Four major outlier periods were identified: the late-1980s construction boom, the early-1990s recession trough, the 2008–2009 financial crisis dip, and a post-2020 pandemic-driven surge — each flagged using IQR-based statistical bounds.
• Ontario and British Columbia consistently generate the most extreme housing start values — both highs and lows — while smaller provinces such as Prince Edward Island and New Brunswick remain comparatively stable across the full 38-year period.
• 75% of all monthly records fall at or below 27 units (IQR: Q25=0, Q75=27), underscoring how concentrated low-activity observations are and how a small number of large urban centres account for the vast majority of national housing construction.
