History World War II Concern was expressed in the Canadian Parliament as early as September 1939 for the security of the Dominion of Newfoundland (which was not yet a part of Canada) in the event of a German raid or attack. It was felt that a permanent airfield defense facility was needed and as a result discussions were carried out among Canada, Newfoundland and the United Kingdom during 1940. In late 1940 the Canadian Government agreed to construct an air base near St. John's. Early in 1941, Canadian Prime Minister William Lyon Mackenzie King informed Newfoundland Governor Sir Humphrey T. Walwyn of the intended location in Torbay. Newfoundland agreed, but stipulated that Canada was to assume all expenses and that the aerodrome not be used for civil purposes without first receiving Newfoundland's permission. The Canadian Government agreed, and in April 1941 McNamara Construction Company began construction on the runway. At a cost of approximately $1.5 million, a pair of runways, taxiways, aprons, hangars and other facilities were built and in operation by the end of 1941. The Royal Canadian Air Force (RCAF) officially opened Torbay Airport on December 15, 1941. It was jointly used by the RCAF, Royal Air Force (RAF), and the United States Army Air Corps until December 1946. On October 18, 1941, three American B-17 Flying Fortress and one RCAF Digby made the first unofficial landings on the only serviceable runway available. Later that month a British Overseas Airways Corporation B-24 Liberator en route from Prestwick, Scotland, to Gander, made the first sanctioned landing during a weather emergency. The first commercial air service at the facility went into operation on May 1, 1942, with the arrival at Torbay of a Trans-Canada Air Lines Lockheed Lodestar aircraft with five passengers and
