Transport Canada is asking for the public's help.
The agency says on May 11th, a pilot of a DV20 Katana aircraft reported passing a drone on his departure from Windsor Airport at roughly 1000 feet.
In a statement to AM800 News, Transport Canada says the aircraft continued its flight with no further issues.
The agency added there was insufficient evidence to identify the drone's operator but police were notified.
Anyone with information is asked to get in contact Transport Canada or police.
Transport Canada says should evidence of non-compliance with the Aeronautics Act or the Canadian Aviation Regulations be found, appropriate action will be taken.
