Canadian Medical Certificate Categories (1-4)

Transport Canada Civil Aviation certifies pilot medical fitness through a system of four categories, numbered 1, 2, 3, and 4. Each category has its own medical standard set out in the Canadian Aviation Regulations and Standard 424, and the categories descend in strictness: Category 1 has the most demanding requirements and Category 4 the least. Which category a person needs depends on the permit or licence they hold or are seeking.

In broad terms, Category 1 is required for the most advanced roles — airline transport and commercial pilots, flight engineers, and multi-crew flying. Category 2 is the medical for the air traffic controller licence. Category 3 supports private-level flying such as the Private Pilot Licence. Category 4 is the entry-level self-declared medical that supports recreational and student operations, including the Recreational Pilot Permit, the student pilot permit, glider pilot permits, and ultra-light aeroplane permits.

Category 4 is distinctive because it is not built around a full aviation medical examination. Medical fitness for Category 4 is normally established through a Civil Aviation Medical Declaration: the applicant completes the declaration, and a physician licensed to practice medicine in Canada signs the relevant part — for a student pilot permit or Recreational Pilot Permit, an applicant has Part B countersigned by a family physician. An applicant who meets the medical conditions stated on the declaration and has it properly signed is deemed to meet the Category 4 medical standard. Applicants who have had certain medical conditions may still need an examination by a Civil Aviation Medical Examiner (CAME).

The most important thing for anyone comparing systems is that Canada's numbered categories are NOT the same as the ICAO-style Class 1, Class 2, and Class 3 medicals used in the FAA, EASA, and UK systems, even though the numbers look similar. A Canadian Category 1 is not interchangeable with an FAA First-Class medical or an EASA Class 1 medical; the four-category Canadian scheme is its own national framework with its own standards and its own mapping of category to privilege. In particular, there is no Canadian 'Category 3' that corresponds to an FAA Third-Class or EASA Class 2 medical simply because the numbers are close — the correspondence has to be worked out by privilege and standard, not by number. Category 4 self-declaration is broadly comparable in spirit to lighter-touch medical routes elsewhere, such as the FAA's BasicMed under 14 CFR Part 68 or the UK Pilot Medical Declaration, but the eligibility, thresholds, and paperwork are specific to Canada and do not cross over. A medical issued under one country's system does not automatically satisfy another's.

For Canadian flight schools and flying clubs, the four-category system determines which members may fly which operations, and mismatches are easy to make because the category numbers invite false comparison with ICAO Class 1/2/3 medicals. A member who trained abroad may hold an FAA or EASA medical that has no automatic standing in Canada, and a Canadian Category 4 self-declaration authorizes only the limited permits it supports.

The self-declared nature of Category 4 adds a verification burden: the operation needs to confirm that a recreational or student member actually holds a valid Category 4 declaration, properly countersigned, and is only flying operations that category permits. Treating a Category 4 declaration as if it were a full private-level medical, or assuming a foreign medical is valid for Canadian operations, is exactly the kind of gap that undermines an otherwise compliant operation.

Aviatize records each pilot's medical as a structured attribute tied to its issuing authority and category, so a Transport Canada Category 1, 2, 3, or 4 is stored as a Canadian instrument — distinct from an FAA First/Second/Third-Class or an EASA Class 1/2/3 medical, and never silently equated with them by number. Category 4 self-declarations are tracked with their own validity so their limited scope is preserved.

The Compliance & Auditing and Smart Planning & Booking modules then enforce the right relationship between a member's medical category and the operation they are booking, flagging an expired or missing medical and blocking a booking where the category does not support the intended flight. That keeps the Canadian categories cleanly separated from the ICAO-style class systems across a mixed membership.
