Over the last ten years, TREB has been drawing attention to the housing supply issue in the GTA. Increasingly, policy makers, research groups of varying scope and other interested parties have acknowledged that the lack of a diverse supply of ownership and rental housing continues to hamper housing affordability in the GTA. Taking 2019 as an example, we experienced a strong sales increase up against a decline in supply. Tighter market conditions translated into accelerating price growth. Expect further acceleration in 2020 if there is no relief on the supply front,” said Jason Mercer, TREB’s Chief Market Analyst.
