Scholars have not paid much serious attention to public or "social" housing in Canada. Of course there was not much of it to speak of before the Second World War. Since then, through the ups and downs of federal policy, a good deal of publicly-subsidized rental and co-op housing has been built, especially in the larger cities where need has been greatest. Many planning and policy studies have been written in connection with specific projects, but the larger picture has remained elusive: what has been the overall contribution of subsidized housing to the urban housing stock, and how has that stock been produced and managed? Metro's Housing Company takes us one step towards answering these questions for Canada's largest city.
