Treaty No. 3 was negotiated and entered into in October 1873. This Treaty area lies mostly within the borders of Ontario; however, Manitoba’s Buffalo Point First Nation is a party to Treaty No. 3.
Manitoban communities that share in the benefits and obligations of Treaty No. 3 include: Falcon Lake, Lac du Bonnet, Middlebro, Point du Bois and many more. Much of Whiteshell Provincial Heritage Park is within the Treaty No. 3 area.
