Social housing funding refers to provincial government financial support for affordable and subsidized housing development and operations. Provinces provide capital grants for building new social housing, operating subsidies to cover gaps between tenant rents and operating costs, and rent supplement programs helping tenants afford private market housing. Social housing includes public housing operated by housing authorities, non-profit housing operated by community organizations, and cooperative housing. Federal-provincial housing agreements provide additional funding through programs like the National Housing Strategy. Demand for social housing far exceeds supply in most Canadian communities, creating long waiting lists. Funding adequacy and allocation approaches are ongoing policy debates as housing affordability challenges intensify.
