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
Engines1
Engine makeWho built the engine. The register only records this where the engine isn't implied by the aircraft's type certificate — mostly ultralights and homebuilts.Rotax Series
SeatsThe register only records a seat count for ultralights, where one seat versus two is what separates the categories. It's blank for everything else, so no number here doesn't mean no seats.2
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.435.45 kg · 960 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.CSJ4, 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.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.CH20701-2107
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.Quad City Ultra Light Corp
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.C0B68E
Registration
Registration typePrivate, Commercial or State. Commercial means the registration permits use for hire or reward — charter, flight training, aerial work. It describes the registration, not who owns the aircraft.Private
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.Advanced Ultra-light
Registered sinceWhen the current registration took effect. A recent date usually means the aircraft changed hands or was re-registered — it is not the date it was built.29 May 2026
Where C-IRDL is, and how to track it
C-IRDL transmits ADS-B under the 24-bit address C0B68E. 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 are on the ground most of the time — if a tracker shows nothing, it is very likely parked rather than missing.
