The RPAS was part of a York Police Services operation at Richmond Hill. The instructor of the aircraft reported that they had just turned from base to Runway 15 at Toronto, and were established and stable, when they felt a jolt that pushed them back on their seat.
They thought they had hit a large bird and proceeded to land. There was no change in configuration or power since they were about to land. When exiting the aircraft, they were shocked to see a major dent on the left underside of the engine cowling and the airbox was also bent.
A few hours later, a police detective confirmed a York Regional Police drone had struck their aircraft. The aircraft suffered major damage, including a propeller strike.
