During late 1935, the first of an initial batch of 16 Rapides were shipped to the manufacturer's Canadian branch, de Havilland Canada, for modification and re-sale purposes. Canadian aircraft received various changes, including an extended dorsal fin and a modified undercarriage arrangement, allowing for either wheels, skis, or floats to be interchangeably installed, dependent upon usage and weather conditions. The sole Canadian prototype, "CF-AEO", was sold onto Quebec Airways in June 1935. Further Rapides were delivered to other customers in Canada, such as Canadian Airways, who used it on their West Coast and maritime routes.
