The association between the Canadian Crown and Indigenous peoples of Canada stretches back to the first decisions between North American Indigenous peoples and European colonialists and, over centuries of interface, treaties were established concerning the monarch and Indigenous tribes. Canada’s First Nations, Inuit, and Métis peoples now have a unique relationship with the reigning monarch and, like the Māori and the Treaty of Waitangi in New Zealand, generally view the affiliation as being not between them and the ever-changing Cabinet, but instead with the continuous Crown of Canada, as embodied in the reigning sovereign.  These agreements with the Crown are administered by Canadian Aboriginal law and overseen by the Minister of Indigenous and Northern Affairs.
