The Chiefs of Ontario serves as a political forum and secretariat for the 133 First Nations in Ontario.
The Chiefs of Ontario held its first All Ontario Chiefs Annual Conference in 1975. At this gather a Joint First Nations Coordinating Committee was formed. This was unincorporated federation of the four major Ontario First Nations Organizations. The goals was to create a single representative political body for representation at the Assembly of First Nations (at the time the National Indian Brotherhood). The representative committee evolved into the Chiefs of Ontario.
