C-GGOK, a de Havilland DHC-8-402 aircraft operated by Jazz Aviation Lp, was conducting flight JZA8975 from Montreal/Pierre Elliott Trudeau Intl, QC (CYUL) to Ottawa/MacDonald-Cartier Intl, ON (CYOW). During the final approach to Runway 07 at 1500 feet AGL, the flight crew briefly observed an unmanned aerial vehicle (UAV) at their 11 o’clock position, approximately 4.2 nautical miles from the threshold of the runway. The pilot flying made a small roll input as an evasive maneuver and the UAV passed just under the left wing of the aircraft. There was no damage to the aircraft, and no reported injuries to the occupants.
