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

Max take-off weightMaximum take-off weight: the heaviest the aircraft may legally be when it starts its take-off roll, including fuel, people and baggage. It's the number that decides what licence and ratings you need, and what it costs to park.2,359 kg · 5,200 lb
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.Québec, 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.27-7554067
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.Piper Aircraft Corporation
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.C06997
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.Commercial
AirworthinessRestricted: approved for specific work rather than general use — crop spraying, survey and similar. The permitted operations are set out on the certificate itself.Special Certificate of Airworthiness - Restricted
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.1A10
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 2025
Where C-GNZQ is, and how to track it
C-GNZQ transmits ADS-B under the 24-bit address C06997. 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.

Transport Canada describes CADORS entries as preliminary and unsubstantiated, and subject to change. Reports reach the system when somebody files one, so a clean record doesn't prove an aircraft has never been damaged. It doesn't replace a title search, an AD check, a pre-purchase inspection or the logbooks. 3 entries have a Transportation Safety Board file number; those are investigated separately and the TSB publishes its own reports.
