Ontario’s housing market, once the epicenter of Canada’s real estate boom, has seen a dramatic reversal over the past three years, with some cities experiencing striking price drops and plummeting sales. According to a new report from real estate brokerage Zoocasa, the market correction is hitting Canada’s priciest regions the hardest, and Ontario is feeling the brunt.
Data from the Canadian Real Estate Association, analyzed by Zoocasa, reveals that home prices in cities across Ontario have steadily declined since peaking in early 2022. Hamilton stands out as the hardest-hit city, where the average home price plunged from $1,104,441 in February 2022 to $813,548 in 2025. That’s a drop of nearly $291,000. In Kitchener-Waterloo, prices dropped from just over $1 million to $786,766, while homes in the Niagara Region fell from $859,477 to $672,804.
The price dip is not just reflected in averages, but also in individual property losses. In February 2025, a Mississauga home sold for $445,000 less than its 2022 purchase price, while an Oshawa property changed hands at a $510,000 loss — sobering reminders of how far the market has fallen from its pandemic-driven highs.
Sales activity has also slowed significantly, particularly in high-priced areas. In the Greater Toronto Area, sales dropped by 55.6 per cent between 2022 and 2025. Kitchener-Waterloo saw the steepest decline at 58.5 per cent, followed by Ottawa at 51.7 per cent and Hamilton–Burlington at 50.9 per cent. The sharp pullback, according to Zoocasa, is a direct consequence of rising borrowing costs. As interest rates surged, so did mortgage payments, deterring potential buyers, building up inventory, and driving prices downward.
The slowdown has not been uniform, however. Despite overall declines, some cities such as Sudbury, parts of the GTA, and the Niagara Region experienced modest price rebounds between February 2024 and February 2025. Still, these upticks offer only limited relief in a market clouded by broader economic uncertainty and the ongoing impact of trade tariffs.
Zoocasa notes that the more expensive the market, the more susceptible it is to financial pressure. “As borrowing costs surged, so did monthly payments, creating widespread buyer hesitation,” the report explained. “In turn, sales froze, inventory built up, and prices began to soften. It’s a clear cause-and-effect cycle: the more expensive the market, the more fragile it becomes under financial pressure.”
