The Department of Indian Affairs is the federal body engaging with First Nations in a fiduciary relationship. In 1860, the responsibility for Indian Affairs was transferred from the British Crown to the Province of Canada. Since the transfer, the responsibility for Indian Affairs was passed to various government departments between 1873-1965. In 1966 the Department of Indian Affairs and Northern Development was created. They would later change name to the Indian Northern Affairs Canada. Today the department is known as Aboriginal Affairs and Northern Development Canada.
