Canada’s housing problems start with RENT CONTROLS, which is a municipal problem; in the 1990s, CMHC and the Canadian Federal government in general went on a mission to make more Canadians homeowners.
This mission clearly failed, but because the FEDERAL government got involved in Local JURISDICTIONS, fewer rental apartments were being built. You also have to factor in far-left activist judges, who make most Canadians not want to be landlords.
