***Current Information, directly from the Official Canadian Civil Aircraft Register database.***
You can check aircraft movements on websites like Flightaware.com but only if an aircraft has filed a flight plan and is flying under instrument rules. The flights do not get tracked if an aircraft is flying under visual rules.
I checked the above tail numbers on Flightaware and there have been no instrument flights tracked for any of these aircraft.
