Medical Certificates and Fitness to Fly
Which medical category the PPL needs, how long it lasts before and after age 40, and the rules that ground you temporarily — illness, drugs, alcohol, pregnancy and blood donation.
In this unit you will learn to
- State the medical certificate category required for the PPL and its validity periods under and over age 40.
- Recall when a pilot must not exercise licence privileges for medical reasons.
- State the alcohol rule for crew members.
Why it matters
The medical certificate is the licence's heartbeat: when it stops, every privilege stops with it. And between medicals, the law trusts you to ground yourself — after a rough illness, a new prescription, a late evening, a blood donation. Both halves are tested: the fixed validity numbers, and the self-assessment rules that no doctor can apply for you.
The certificate and its lifespan
CAR 404.03 forbids exercising licence privileges without a valid medical certificate of the appropriate category. For the private pilot licence that is a Category 3 medical (a Category 1 — the commercial standard — also qualifies). It is issued after an examination by a Civil Aviation Medical Examiner (CAME).
Validity for the PPL, from the table in CAR 404.04:
- under 40 years of age: 60 months (5 years);
- 40 or older: 24 months (2 years).
Two administrative details are exam favourites. The validity period is calculated from the first day of the month following the examination — a medical on 10 March runs to 1 April plus 60 (or 24) months. And when circumstances prevent a timely renewal, the Minister may extend a certificate by up to 60 days, provided you apply while it is still valid.
Grounding yourself: CAR 404.06
You must not exercise your privileges when any of the following could impair your ability to fly safely:
- you suffer from an illness, injury or disability;
- you are taking a drug — prescription or otherwise; or
- you are receiving medical treatment.
Pregnancy and childbirth have their own timeline: privileges stop at the thirtieth week of pregnancy and for six weeks after giving birth, with a medical examiner able to restore them earlier after an examination.
Beyond CAR 404.06, the medical declaration you sign obliges you to report to Transport Canada any condition likely to make you unfit for more than 30 days. And good airmanship applies the informal I'M SAFE check — Illness, Medication, Stress, Alcohol, Fatigue, Eating — before every flight, not just when a rule forces the question.
Alcohol and drugs
CAR 602.03 forbids acting as a crew member:
- within 12 hours after consuming an alcoholic beverage;
- while under the influence of alcohol — the 12 hours is a floor, not a guarantee of sobriety; a heavy night can leave you impaired far longer; or
- while using any drug that impairs your faculties.
CAR 602.02 backs this up from the operator's side: nobody may be required to fly when fatigued or otherwise unfit.
