Under the new program, the Government provided mortgage interest assistance in the form of non-repayable subsidies to reduce the effective interest on the mortgage to 2%, as well as an amount for operations and maintenance. [...] In 1986, the calculation was revised so it was then based on the difference between the monthly mortgage payment and the 25% RGI of the household income – the so-called “deep subsidy”. [...] The Operating Agreements for the Urban Native Housing Program and those for mainstream housing corporations were basically the same, but with two key differences: the UNH Agreements provided for the position of Tenant Counsellor, and the UNH organizations were to provide services to and for First Nations, Métis or Inuit peoples. [...] In 1996, the federal government pursued negotiations with the provinces and territories to transfer all social housing programs, including Aboriginal housing, to the administration of the provinces and territories. [...] In making the transfer, the provinces are required to respect the terms of the Operating Agreements that had been signed between the UNH Program organizations and CMHC.
