Fort SevernFirst Nation is located on Hudson Bay and is the most northern community in Ontario, Canada. As of 2001, the population was 401, consisting of 90 families in an area of 40 square kilometres. The legal name of the reserve is Fort Severn 89 as most Indian reserves in Canada have a number after the name.
Fort Severn served as one of the earliest trading posts in the new world. It was established by the Hudson's Bay Company in 1689. When the treaty was signed, the federal government, with the consent of the leaders at the time, set aside land for a native reserve in the Rocksand area at the junction of the Severn and Sachigo Rivers. In 1973, the reserve was relocated to the opening of the Severn River. The reserve achieved full status on January 11, 1980.
