The American military left Iqaluit in 1963, as their development of the intercontinental ballistic missiles (ICBM) diminished the strategic value of the DEW line and Arctic airbases. Canada continued to operate an administrative and logistical centre for much of the eastern Arctic at Frobisher Bay. In 1964, the first local elections were held for a community council, and in 1979 for the first mayor. The founding of the Gordon Robertson Educational Centre, now Inuksuk High School, in the early 1970s at Iqaluit confirmed the government's commitment to the community as an administrative centre. At the time of its founding, this was the sole high school operating in what constituted more than one-seventh of Canadian territory.
