 With a much lower population, powers of the territory's head of government reverted to a federal and Crown representative appointed by the Prime Minister of Canada, this time with the title "Commissioner of Northwest Territories".Beginning in 1951, and increasingly in 1967, powers were transferred back to an elected assembly.In 1980, the head of this assembly regained the title of premier, and in 1985 the premier became chair of the Executive Council and full head of government.
