RCAF Station Knob Lake (Sector Control Station 300) bordered the northern Quebec mining community of Schefferville. Knob Lake began as an RCAF Detachment in August 1955, with 20 Officers and 80 men with its headquarters in the Bell Telephone building. During that period, 108 Communications Flight (KU) from Bagotville Quebec and 408 Photo Reconnaissance Squadron from Rockcliffe Ontario, flying out of Knob Lake were involved in the propagation testing of the Doppler principle operation called Backlash III. Knob Lake attained station status in June 1957 and was operational by the beginning of the next year. The daily records report a much anticipated shipment of essential supplies on 25 October 1956; that day the Coke ration came in, all 300 cases of it. RCAF Station Knob Lake was shut down in April 1965. The 5500 foot paved runway is now used as a Transport Canada facility.
