 Métis French is best preserved in Canada, Michif in the United States, notably in the Turtle Mountain Indian Reservation of North Dakota, where Michif is the official language of the Métis that reside on this Chippewa reservation.The encouragement and use of Métis French and Michif is growing due to outreach within the provincial Métis councils after at least a generation of steep decline.Canada's Indian and Northern Affairs define Métis to be those persons of mixed First Nation and European ancestry.
