Equipped with the aircraft, the first bush flights occurred when fire patrol and aerial photography began in the summer of 1919 in the St. Maurice River valley. Graham and Kahre continued this service for two more seasons, but it became so expensive that the Laurentide Company underwrote the operation. In response, it was split into a separate company called Laurentide Air Services Ltd. with Wilson as president and former Royal Naval Air Service instructor and barnstormer William Roy Maxwell as vice president. These were the first bush flights in Eastern Canada.
