Across Canada’s major metropolitan areas, housing construction is showing a clear split between homeowner-oriented projects, including single-family homes and condos, and purpose-built rentals. Construction on the first group is dropping to levels not seen since the Financial Crisis, while the latter is experiencing a surge of new activity. This divergence is reshaping the supply outlook for both ownership and rental markets, with very different implications for future resale inventory, rental vacancies, and overall housing balance.National Divergence in Construction ActivityOn a national level, the shift is striking. Over the past year, purpose-built rental starts reached 102,000 units, which is nearly equivalent to the combined total of new single-family and condo starts. This imbalance suggests that the market will see a wave of new rental supply over the next two years, but very little replenishment of homeowner-oriented inventory.The data indicate that the country is at a turning point. While developers and investors are moving aggressively into rentals, traditional ownership housing construction is retreating. The result is a housing pipeline tilted heavily toward one segment of the market.Metropolitan Construction TrendsAt the municipal level, there are two distinct patterns. In Canada’s largest metropolitan areas of Toronto and Vancouver, construction of ownership housing is contracting sharply, while rental development is the only segment showing growth. In Toronto, both single-family and condo construction were down by nearly 15% compared with a year earlier, while rental construction increased by 14.8%. Vancouver showed a similar pattern: single-family projects fell by 12.8% and condos by 5.8%, but rental activity still managed to climb by 5.4%.In contrast, Alberta’s markets are experiencing strong overall construction activity, but the expansion is being driven almost entirely by rentals, which have surged by more than 40% year-over-year in both Calgary and Edmonton. In Calgary, single-family activity inched up by just under 1%, while condo construction dropped by 10%. Edmonton was notable in that it saw strength across all three categories, although rentals led the expansion, with increases of 14.7% for single-family homes and 22.2% for condos.A Market Headed in Two DirectionsThe Canadian housing market is increasingly defined by this split trajectory. The homeowner segment is being starved of new supply, setting the stage for tighter resale markets in the years ahead. Meanwhile, the rental segment is bracing for an unprecedented influx of new units at a time when demand is no longer accelerating.Implications for the Homeowner SegmentThe weakness in single-family and condo starts carries long-term consequences for the ownership market, according to a September Edge Realty Analytics report. The future pool of resale homes will likely shrink. Single-family building permits in Ontario and Vancouver are already hitting new lows, reinforcing the slowdown in future supply.Additionally, while today’s condo market may appear soft, especially in Toronto, the market environment points to an eventual undersupply situation in the 2030s. With fewer completions expected in the early part of that decade, the market risks running short of inventory just as demographics and ownership demand recover.Implications for the Rental SegmentThe rental side of the market is moving in the opposite direction, with an unprecedented supply wave already in motion.Nationally, 160,000 purpose-built rentals, equivalent to about 7% of the current primary stock, are under construction. This is in addition to record levels of secondary supply from condos, much of which will also be rented out. Furthermore, several major cities are on track for significant growth. Vancouver’s rental stock is expected to expand by 17%, Calgary’s by 17%, and Ontario metros by between 7% to 12%.This surge comes as rental demand is weakening. The non-permanent resident population, a key driver of rental demand in recent years, now potentially faces declines with changing immigration policies. With record new supply and softer demand, vacancy rates are likely to rise.
