The Aporia · Canada’s housing supply gap narrowly improves, but pace of construction could slow, CMHC says

Canada's housing agency, CMHC, estimates that between 417,000 and 469,000 new homes are needed annually over the next decade to restore pre-pandemic affordability by 2036. This is down slightly from their previous estimate of 430,000-480,000 units per year, but they warn that new home construction may slow instead of increasing as needed. According to CMHC's latest report, the housing supply gap has narrowed in Toronto and Calgary, but grown larger in Montreal and Ottawa. The agency's deputy chief economist cites slower population growth as a factor contributing to declining housing costs.

Story summary

The Canada Mortgage and Housing Corp. (CMHC) released a report saying that Canada's housing supply gap has narrowed over the past year, but still needs to be addressed. According to the report, the country requires between 417,000 and 469,000 new housing units per year across ownership and rental markets over the next decade to restore pre-pandemic affordability by 2036. This is a slight decrease from the previous estimate of 430,000 to 480,000 new units annually. Despite some recent gains in affordability, particularly in Toronto, CMHC warns that slowing home construction could put these gains at risk and lead to an even greater shortage when demand increases again.
