Housing starts and pre-sales in much of Southern Ontario have earned failing grades and are on track to get even worse, a new study warns — a situation that “should alarm policymakers across all three orders of government.” The report from University of Ottawa’s Missing Middle Initiative compares housing starts and sales in 34 municipalities across the Greater Toronto Area and neighbouring Southern Ontario cities for the first six months of 2025 with the same period from 2021–2024. It found starts are down 40% relative to that four-year average, with pre-construction condo sales plunging 89 per cent and other homes 70 per cent. The reduction in starts has direct employment implications, and the collapse in pre-construction sales, the study says, is “a clear indication that Ontario’s housing situation will get worse before it gets better, and that market weakness is not isolated to the condo market.” …The study paints a similarly bleak picture for the first half of 2025.
