The HBC bought out Révillon Frères in 1936 and continued its trade monopoly here until 1958. In 1927 an Anglican mission was established, followed by a post office and Royal Canadian Mounted Police (RCMP) detachment in 1935, a nursing station in 1947, and a school in 1951. From this time on the Inuit started to give up their traditional nomadic way of life and live permanently in the community. A cooperative store was formed in 1962. Inukjuak was legally established as a municipality in 1980.
