Airframe typeWhether Transport Canada classes it as an aeroplane, a helicopter, a glider, a balloon or a gyroplane.Aeroplane
Engine typeHow the engine makes power. Piston engines run on avgas like a car engine; turboprops and jets burn turbine fuel, cost far more to overhaul, and are usually reserved for bigger or faster aircraft.Piston

Where it's based
BasedThe city or airport Transport Canada holds as the aircraft's base. Where the field holds a four-letter code like CYXE, that's the airport's ICAO identifier.Lasarre, Quebec
Transport Canada officeThe Transport Canada regional office that administers this registration. It follows the owner's address, so it isn't always the nearest office to where the aircraft actually sits.Dorval
Identity
Serial numberThe manufacturer's own number for this individual airframe, stamped on a plate. Unlike the registration, it never changes. It identifies the aircraft across every country it's ever been registered in.11AC1147X
Built inWhere the aircraft was manufactured. Most of Canada's fleet was built in the United States.U.S.A.
ICAO 24-bit addressA unique 24-bit number your transponder broadcasts with every Mode S and ADS-B message. Flight trackers key on it rather than the tail number. Canada's block runs C00000 to C3FFFF, which is why Canadian aircraft nearly all start C0 to C3. Transport Canada assigns it against the registration, so it changes if the aircraft is re-registered.C07ABA
Registration
Registration typePrivate, Commercial or State. Commercial means the registration permits use for hire or reward, like charter, flight training or aerial work. It describes the registration, not who owns the aircraft.Private
AirworthinessOwner-maintenance: a Canadian category letting the owner maintain the aircraft themselves without a licensed engineer signing the work off. Three things a buyer should know — it cannot be changed back to a standard Certificate of Airworthiness, it isn't recognised outside Canada, and it typically reduces resale value because it narrows the buyer pool.Special C of A - Owner-maintenance
Basis of registrationThe rule the aircraft is registered under. Most are registered against a type certificate, meaning they're a factory design approved by the regulator; amateur-built and ultralight aircraft come in under their own standards.CAR Standard 507.03(6) - Owner Maintenance Aircraft
Registered sinceWhen the current registration took effect. A recent date usually means the aircraft changed hands or was re-registered. It isn't the year it was built.9 May 2019
Where C-GUMJ is, and how to track it
C-GUMJ transmits ADS-B under the 24-bit address C07ABA. Trackers key on that address rather than the tail number, so it finds the aircraft even on flights flown under a different callsign. Transport Canada assigns the address against the registration, so it changes if the aircraft is re-registered.
Most private aircraft spend most of their time on the ground. If a tracker shows nothing, it's probably just parked.
The owner of record and the certificate history are on Transport Canada's own lookup: see C-GUMJ on the Transport Canada register →
