You can obtain a Category 4 medical certificate two ways: complete the Category 4 Medical Declaration Form, countersigned by a family physician if your application type requires it, or undergo an examination by a Civil Aviation Medical Examiner. Renewal requests must reach Transport Canada within 60 days of expiry, examiner fees are set by the physician rather than Transport Canada, and if you have a condition listed in Part B of the form you must use the examiner route. If a standard is not met, flexibility provisions and appeal options exist.
What the Category 4 medical certificate is
Category 4 is the medical category behind entry-level recreational aviation privileges in Canada. It is satisfied through a declaration or an examiner examination, not a written knowledge test.
Canadian aviation medical categories describe the level of medical fitness needed for different aviation activities, with Category 1 at the professional end. Category 4 sits at the recreational end of that range. Transport Canada issues medical certificates once an examination report or declaration shows you are medically fit, or fit with a restriction or limitation.
The declaration route is tied to specific permits in the standards: the student pilot permit and pilot permit for ultra-light aeroplanes, the pilot permit for recreational aeroplanes, the student pilot permit for gliders, and the glider pilot licence. Your application materials tell you which medical evidence your permit type requires, so confirm your permit type before choosing a route.

Route one: the Medical Declaration Form
You complete the Category 4 Medical Declaration Form, confirming you have never suffered any condition listed in Part B, with a family physician's countersignature for certain application types.
To qualify for this route, you must confirm you have never suffered from any of the medical conditions listed in Part B of the Category 4 application form. If you have suffered from one or more of those conditions, you cannot use the declaration alone; you must instead get a medical examination from a Civil Aviation Medical Examiner.
If you are applying for a student pilot permit for aeroplanes or a pilot permit for recreational flying, a family physician must countersign Part B of the form. You then email the completed form to any Transport Canada Centre, using the subject line format "Category 4 Medical Declaration Form + last name + file number (if known)". Transport Canada invoices you once the medical label has been processed and issued.

Route two: the examiner examination
The alternative is a medical examination by a Civil Aviation Medical Examiner (CAME), a physician Transport Canada has appointed to assess aviation medical fitness.
Only a physician designated by Transport Canada as a CAME may perform this examination. You contact a CAME from Transport Canada's published list to book an appointment, and the physician assesses your medical fitness on a medical examination report that goes to Transport Canada. For an initial certificate, this is the route you take if you cannot make the Part B declaration, and it is also the standard path for most other medical categories.
Prepare for the appointment by bringing photo identification, your medication list with dosages, your lens prescription if you wear them, your family doctor's contact details, and your pilot licence or permit number if you hold one. Pilots should also know their total flight time over the last 12 months. Having your medical history, past test results, and family medical history on hand speeds up the appointment.
- Photo ID and current medications with dosage and frequency
- Lens prescription, family doctor contact, and licence or permit number
- Flight time over the last 12 months, for pilots
- Medical history, past test results, and family medical history

What happens after you apply
Transport Canada reviews the report or declaration, may request more tests, and mails you a medical certificate label with any restrictions printed on it.
After the examination, Transport Canada reviews and assesses the report. If more tests are needed, Transport Canada contacts you with the required next steps, and completed results must go back through a CAME. If the needed tests are not completed, no medical certificate can be issued.
If you are assessed as medically fit, your certificate arrives as a label mailed to you, with any restrictions, such as a requirement to wear glasses, printed on it. You place the label in your aviation document booklet, which is your proof of medical fitness. Aviation students receive a standalone medical certificate instead, because they are not issued an aviation document booklet.

Validity periods and renewing on time
Validity depends on your age and licence or permit type, ranging from six months to five years in the examples given. Category 4 renewal requests should be submitted within 60 days of expiry.
Transport Canada gives the range in general terms: medical exams are required as often as every six months for professional pilots aged 40 and over, and as seldom as every five years for private or balloon pilots under 40. The full table of validity periods for every licence and age combination appears in Standard 424 Appendix II, so check it for your specific case.
If you hold a Category 4 certificate, submit your renewal request within 60 days of expiry so there is enough time to process a new certificate before the old one lapses. Renewal can happen by in-person exam or, if you qualify, by telemedicine, meaning a telephone, audio, or video assessment.
Telemedicine has strict limits. As of March 4, 2025, you are only eligible if your previous examination was in person. You must renew in person if you are a new applicant, if your certificate's validity ended before March 17, 2020, if your last examination was by telemedicine, or if a CAME or Transport Canada asks you to attend in person. Certificates renewed by telemedicine are valid for a maximum of 12 months, reduced to six months if you are 60 or older, or 40 or older and conducting a single-pilot operation carrying passengers.

What the certificate costs
The examiner sets and charges the examination fee; Transport Canada does not set it. A separate Transport Canada processing fee may be invoiced afterwards.
Your CAME charges a fee for the medical exam and will tell you the cost; the amount varies because Transport Canada does not set these fees. If you are outside Canada, a Transport Canada-accredited CAME or, for eligible Canadian Armed Forces personnel, a CAF Flight Surgeon can conduct the examination, on the same fee basis.
Separately, Transport Canada may invoice a processing fee once your certificate is issued. You pay it through the online invoice payment form using your customer number, invoice number, and payment amount. Budget for both costs rather than assuming the examiner's fee covers everything.

When a standard is not met: flexibility and appeals
Transport Canada can apply flexibility in special circumstances, and applicants assessed unfit can seek reconsideration or appeal.
Standard 424 allows flexibility in special circumstances, with monocular and paraplegic applicants given as examples. Flexibility requires an accredited medical conclusion that failing the requirement is not likely to affect air safety, along with any special limitations endorsed on the licence and compliance with required conditions. In some flexibility cases a practical flight test is part of the evaluation.
If you are assessed unfit at the regional level, you can submit additional reports from medical examiners, specialists, and laboratories for reconsideration, and you can ask that your file go to the Aviation Medical Review Board. Appeal to the Civil Aviation Tribunal is available where a holder is assessed unfit to exercise licence privileges or a certificate renewal is refused. If Transport Canada cannot certify you as fit, you can request a description of the assessment and your appeal options.

Aeromedical conditions worth understanding
The CAME Handbook covers neurology, cardiovascular disease, diabetes, and asthma in detail. Two supported examples show how condition management interacts with certification.
Insulin-treated diabetes is directly relevant to Category 4: Transport Canada's management framework states that pilots other than existing professional licence holders are considered only for Category 3 or 4 certificates, and the Category 4 column allows fit status with annual reports at low and moderate risk levels. Certification depends on stable control, monitoring, and annual specialist review, all assessed by Civil Aviation Medicine.
The handbook's diabetes appendix sets a flight protocol for insulin-treated pilots: blood glucose must be above 6.0 and not above 15 mmol/L within the 30 minutes before flight, checked every 60 minutes during flight, with 10 g of carbohydrate taken whenever a reading falls below 6.0. The worked exercise below drills that protocol. Asthma is another handbook topic: acute attacks can cause partial or complete incapacitation, in-flight fumes can trigger attacks, and in severe asthmatics, hypoxia can develop at lower altitudes than normal. Note that these protocols come from examiner guidance; your own certification decisions rest with your CAME and Civil Aviation Medicine, and paper study cannot substitute for their assessment.
Worked example
Premise: a pilot holding a Category 4 medical certificate is treated with insulin for diabetes and follows Transport Canada's blood glucose management protocol. Thirty minutes before a flight, the pilot's meter reads 5.4 mmol/L. One hour into the flight, the meter reads 6.8 mmol/L. What must the pilot do at each point, and what testing remains before landing?
Show answer
Before flight: 5.4 mmol/L is below the required minimum, so the pilot must ingest 10 g of readily absorbable carbohydrate and obtain a compliant reading, above 6.0 and not above 15 mmol/L, within the 30 minutes before flight before departing. In flight: 6.8 mmol/L is compliant, so no carbohydrate is needed at that reading; the pilot continues measuring every 60 minutes. Thirty minutes before landing, the pilot must measure again and take 10 g of carbohydrate if the reading is below 6.0 mmol/L.
The protocol requires pre-flight glucose above 6.0 and not above 15 mmol/L within 30 minutes before flight, monitoring every 60 minutes during flight, and 10 g of carbohydrate whenever a reading falls below 6.0. The tempting error is treating 5.4 mmol/L as close enough to depart, when the protocol requires action and a compliant pre-flight reading. The 6.8 mmol/L reading can look high by everyday standards, but within this protocol it needs no intervention, because the concern is hypoglycemia. Readings above 15 mmol/L during flight trigger different rules: no further caloric intake until retesting, and a pilot flying solo must land as soon as safely possible.

Practical mistakes to avoid
The real failure points are administrative: missing the renewal window, skipping a required countersignature, or assuming a condition bars certification when it simply changes your route.
Each mistake below follows directly from the published process, and every one is avoidable with a little planning.
- Requesting renewal too late: submit your Category 4 renewal within 60 days of expiry so processing finishes before the certificate lapses.
- Assuming a Part B condition is an automatic bar: it routes you to a CAME examination rather than ending the application.
- Skipping the family physician countersignature when applying for a student pilot permit for aeroplanes or a pilot permit for recreational flying.
- Booking a telemedicine renewal without checking eligibility, for example when your last examination was already by telemedicine.
- Budgeting only for the examiner's fee and forgetting the possible separate Transport Canada processing invoice.
- Failing to complete requested follow-up tests, which blocks issuance or suspends an existing certificate.

Your next steps
Decide your route, book or download accordingly, and calendar the renewal window as soon as your certificate is issued.
Start by confirming your permit type, because it determines whether the declaration form applies and whether a countersignature is needed. If you can honestly make the Part B declaration, download the form, arrange any required countersignature, and email it to a Transport Canada Centre with the specified subject line. Otherwise, book an appointment with a CAME and gather the documents listed earlier.
Once your certificate arrives, note the expiry date immediately and set a reminder at least 60 days ahead. Check the telemedicine eligibility rules before assuming a remote renewal is possible, and keep copies of any required medical reports current so renewals stay routine.
- Confirm your permit type and required medical evidence
- Choose the declaration form or the CAME examination route
- Submit the form by email with the correct subject line, or attend your exam with documents ready
- Pay both the examiner's fee and any Transport Canada invoice
- Calendar your renewal at least 60 days before expiry
