1.2 RPAS Registration, Marking & Ownership

Registration turns an individual aircraft into a known participant in the Canadian aviation system. For RPAS, the rules in the CAR 900.13–900.20 family establish when an RPA must be registered, how it must be marked, who may own and register it, how certificates of registration work, and what happens when ownership or contact details change. Advanced candidates are tested on both the letter of these requirements and the operational habit of carrying access to registration proof on every flight that needs it.

Why Registration Exists

Crewed aircraft have long been registered so authorities can identify owners, enforce safety rules, and investigate incidents. RPAS registration serves the same accountability purpose at drone scale:

• Links a physical aircraft to a responsible owner
• Supports inspection and enforcement after a complaint or occurrence
• Enables marking so a found or observed aircraft can be correlated to records
• Creates a paper (or electronic) trail for transfer, cancellation, and contact updates

Without registration, "who flew what" becomes guesswork. That is unacceptable for Advanced operations conducted near people, aerodromes, or controlled airspace.

Threshold: 250 g and Registration Duty

Under the Part IX registration scheme, an RPA with a maximum take-off weight of 250 g or more is generally subject to registration requirements before it is operated. Micro operations under 250 g sit outside the main registration obligation that applies to larger small and medium RPA used in Advanced work—but most professional Advanced fleets are well above the threshold.

Key exam habits:

• Know the 250 g trigger as a hard memory item.
• Do not assume that "I only fly recreationally" erases registration when the weight threshold and operating rules require it.
• Remember that Advanced privileges do not replace registration; they presuppose a properly registered aircraft when registration is required.

CAR 900.13–900.20 Theme Map

Think of the 900.13–900.20 band as a lifecycle:

You are not expected to recite every subsection number in isolation without context, but you are expected to know that these duties form a connected system: register → mark → carry proof → update → cancel when finished.

Marking and Display of the Registration Number

Registration is incomplete if the aircraft cannot be identified in the field. The marking rules require the registration number to be displayed on the RPA in a manner that meets regulatory expectations—typically so it is durable, legible, and associated with the aircraft structure rather than a temporary sticky note that falls off mid-mission.

Practical compliance points Advanced pilots should internalize:

• Mark the registered aircraft, not a random case or unused airframe.
• Ensure marks remain legible after maintenance, repainting, or payload changes.
• If you swap airframes or major components in a way that creates a different registered unit under the rules, resolve registration identity before flight.
• Do not cover marks with paint, foam, or payloads so thoroughly that identity is effectively hidden.

Marking supports both formal inspection and informal recovery: if a drone lands off-site, a visible registration number helps reunite aircraft and owner and supports investigations.

Owner Qualifications and Accountability

The owner is the accountable person (or organization) on the registration. Owner qualification rules exist so that the registration system is not filled with anonymous or ineligible holders. For exam purposes:

• Ownership and pilotage can be related but are not identical concepts. A company may own the aircraft while a certified employee pilots it.
• The owner remains responsible for registration accuracy, marking, and cancellation duties even when a different person flies.
• Advanced pilot certificate holders who own their own aircraft wear both hats and must satisfy both sets of duties.

Certificate of Registration

The certificate of registration is the formal proof that a particular RPA is registered. In modern practice, registration is managed through Transport Canada’s digital systems (such as the Drone Management Portal ecosystem), and pilots commonly rely on electronic access. Whatever the medium:

• The certificate (or authorized electronic equivalent) must reflect the correct aircraft and current owner data.
• Operating a registration-required RPA without a valid registration is unlawful.
• Photocopying someone else’s registration number onto your airframe is fraud and identity abuse, not compliance.

Access to Registration When Flying

A recurring Advanced exam and field theme is access while operating. It is not enough that registration exists somewhere in a filing cabinet at home if the rules require the pilot to have access to registration information during the flight. Build a pre-flight habit:

1. Confirm the RPA is the registered unit you intend to fly.
2. Confirm marks match the registration record.
3. Ensure electronic or paper proof is available on site.
4. Ensure the pilot certificate and recency proofs are available alongside registration.

Advanced operations amplify this expectation because the operating environment is more complex and more likely to attract scrutiny from aerodrome operators, NAV CANADA processes, or Transport Canada inspectors.

Name, Address, and Other Changes

When the owner’s name or address changes, the registration system must be updated within the timelines the CARs require. Out-of-date contact data undermines the entire purpose of registration: if Transport Canada or another authority cannot reach the owner after an incident, the accountability chain is broken. Treat contact updates as a regulatory duty, not optional account maintenance.

Other changes that affect identity—ownership transfer, destruction of the aircraft, permanent withdrawal from service—also trigger registration actions. Do not "ghost" a destroyed drone by leaving it registered forever without action if cancellation is required.

Cancellation of Registration

Cancellation ends the registration for that aircraft identity. Typical drivers include:

• Aircraft destroyed or permanently withdrawn
• Export or other removal from the Canadian registration context
• Ownership situations that require closing the existing registration
• Regulatory action cancelling registration

After cancellation, you must not continue to operate as if the old certificate still authorized flight. If you replace the aircraft, register the new unit properly rather than recycling marks from a cancelled registration.

Advanced Ops: Registered Drone + Proof Carried

For Advanced candidates, collapse the section into one operational sentence you can recall under exam stress:

Advanced operations require a registration-eligible RPA to be registered, marked, and flown with registration proof accessible—together with pilot certificate and recency evidence.

Common failure modes to avoid in scenario questions:

• Flying an unmarked or wrongly marked airframe
• Using a friend’s registration number on your aircraft
• Assuming Advanced pilot status substitutes for aircraft registration
• Leaving all proof off-site during a multi-day field project
• Ignoring owner address updates after a move

Link Forward

Registration identity will reappear when you study incident reporting, aerodrome proximity, and controlled-airspace authorization. Authorizations and investigations attach to who and what flew—registration is how "what" is known.
