This report provides an overview of Canadian federalism and its impact on housing policy. It examines the shared responsibilities of the federal, provincial, and territorial governments in addressing housing issues, including the allocation of resources, the development of affordable housing, and the regulation of rental markets. The report explores constitutional considerations, such as the division of powers outlined in the British North America Act (now the Constitution Act, 1867), and the implications of the Canada Health Act on provincial health programs. It analyzes specific government initiatives, including measures to mandate low-income units in new constructions, legislative provisions for rent control, and the expansion of federal funding for low-income housing. The report also discusses the government's proposal to amend the Canada Health Act, the interjurisdictional immunity, and the roles of municipalities and the federal government. Finally, it provides recommendations for the federal government on the constitutionality of its suggested housing policies, emphasizing the importance of collaboration, respect for each other's roles, and the need for sustainable and predictable funding to deliver long-term results.
