For how long is a Class 3 medical valid for a private pilot under 40 years of age?

A Class 3 medical certificate is valid for a period of 5 years for private pilots who are under 40 years of age. This regulation is established by Transport Canada to ensure that pilots maintain a standard of health and fitness necessary for safe flight operations. This 5-year validity period is designed to periodically assess the medical fitness of pilots as they age and possibly encounter different health challenges.

Other options present shorter durations which do not align with the regulatory framework for Class 3 medical certificates for private pilots under 40. Hence, those alternatives do not provide the correct period of validity as prescribed by the governing aviation authority.
