Canada’s homebuilders pulled back sharply heading into the second half of 2026. According to CMHC’s latest housing starts data, actual starts in centres with a population of 10,000 or more fell 19% year-over-year in July, with 18,834 units recorded compared to 23,155 units in July 2025. Year-to-date starts are down 4% from the same period last year, at 131,851 units. For GTA buyers, renters, and investors watching a market that’s supposed to be building its way out of an affordability crisis, this CMHC housing starts GTA data is worth paying attention to.

What CMHC’s July Numbers Actually Show

The pullback wasn’t limited to one segment. CMHC’s Housing Market Outlook 2026 flags that starts momentum is expected to keep slowing as economic uncertainty weighs on developer confidence and buyer demand. Rental construction — which has been the one bright spot propping up overall starts activity over the past two years — is also expected to slow through the second half of 2026, as developers respond to higher vacancy rates and softer rent growth in major markets, including Toronto. In other words, both the ownership and rental construction pipelines are downshifting at the same time.

What This Means for GTA Buyers and Investors

Fewer starts today translates into fewer completed homes two to three years from now, at exactly the point in the cycle when population growth and household formation are expected to keep adding pressure to demand. For GTA buyers sitting on the sidelines waiting for more choice, a slower starts environment argues against expecting a meaningful supply-driven correction in pricing over the next few years. For investors, it reinforces that pre-construction and new-build inventory already in the pipeline — condos, purpose-built rentals, and low-rise product already under construction — may hold relative value as the flow of new projects behind them thins out.

Kevin’s Take

I’ve been fielding more questions from clients about timing purchases around supply, and the honest answer is that a slowdown in starts today doesn’t show up as more homes on the market — it shows up as fewer of them, two or three years out. If you’re planning a purchase in the GTA, whether it’s a resale home in Toronto, Mississauga, or Brampton, or a pre-construction unit, this is exactly the kind of data point that should factor into your timeline and financing strategy, not just today’s rate.
