In Canada, affordable housing refers to living spaces that are financially accessible to people with a median household income. Canada ranks among the lowest of the most developed countries for housing affordability. Housing affordability is generally measured based on a shelter-cost-to-income ratio (STIR) of 30% by the Canada Mortgage and Housing Corporation (CMHC), the national housing agency of Canada. It encompasses a continuum ranging from market-based options like affordable rental housing and affordable home ownership, to non-market alternatives such as government-subsidized housing (emergency shelters, transitional housing, and public housing).
