Under NAFTA’s terms, American Specialty Air Service Operators may conduct operations in Canada. If you have any reason to believe that an American operator is conducting operations in Canada without NAFTA authorization, or in an aircraft that is not certified in Canada, please contact HAC without delay. Each summer season, HAC receives two or three calls from operators who have identified N-registered aircraft (occasionally on uncertified or ex-military aircraft) operating in Canada. If you are able to provide specifics (registration, location, date, time, company etc.) relating to the operation of these aircraft to HAC, the Association will follow-up with Transport Canada to determine the status of the operation.
