In the summer of 1940 the Royal Canadian Air Force selected a flat area of farmland between Mont-Joli Station (on the Montreal-Halifax Canadian National Railway mainline) and the Saint Lawrence River for a military airfield. Construction on the aerodrome began in October 1941 and was completed by April 1942 at a cost of $200,000. Three paved runways and 50 buildings were constructed for what became known as RCAF Station Mont-Joli.
Inaugurated on April 15, 1942, RCAF Station Mont-Joli was used as part of the British Commonwealth Air Training Plan for a bombing and gunnery school until the end of World War II. Less well-known was RCAF Station Mont-Joli's critical role during the Battle of the St. Lawrence when RCAF Eastern Air Command used it as a coastal patrol base; during 1942-1944, dozens of Canadian cargo and warships were sunk by German U-boats in an effort to close the critical Saint Lawrence Seaway off to shipping. Aircraft staging out of Mont-Joli were crucial to warding off U-boats and ensuring the safety of shipping out to the eastern tip of the Gaspé Peninsula at Cap-Gaspé.
