As the Second World War advanced, the RCAF needed a more advanced trainer for the BCATP. The existing DH 82C Tiger Moths and Fleet 16B's used for elementary flying training proved to be a significant step down from contemporary service aircraft.

In the spring of 1941, the RCAF therefore decided on a development of the Fairchild Aircraft (US) Company's PT-19 trainer design. The RCAF version was to feature an enclosed cockpit, an improved heating system, equipment changes along with a Ranger piston engine. This modified version was to be known as the Fairchild Cornell in Canada and it rapidly entered production and found favour at elementary flying schools across Canada beginning in 1943. Although not without some in-service problems, the Cornell provided reliable service in its intended role until after the war.
