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.Oshawa, Ontario
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.Toronto
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.18502972
ManufacturerThe full legal name of the company that built it, which is often not the name on the tail. A Cessna 172 built in 2022 was made by Textron Aviation.Cessna Aircraft Company
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.C046BD
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
AirworthinessThe standard certificate: the aircraft conforms to its approved design and is maintained by a licensed engineer. No restrictions beyond the type's own, and it's what buyers and lenders expect to see.Certificate of Airworthiness
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 507.02, 507.03 - Type Certificate
Type certificateThe approval number for the aircraft's design, issued to the manufacturer. Every aircraft built to that approved design shares it, so it's a good way to confirm exactly which variant you're looking at.3A24
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.27 December 1985
Where C-GAUM is, and how to track it
C-GAUM transmits ADS-B under the 24-bit address C046BD. 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-GAUM on the Transport Canada register →
