At what age must a person have a PCOC to operate a motorized vessel in Canada?

In Canada, a person must be at least 12 years of age to operate a motorized vessel under 10 horsepower without supervision. However, if the vessel is 10 horsepower or more, the operator must possess a Pleasure Craft Operator Card (PCOC), regardless of their age. Therefore, it is correct that a person must have a PCOC at the age of 12 to operate a vessel legally.

The significance of this age requirement is that it ensures that younger operators are informed about safety regulations, navigation rules, and responsible boating practices. This is critical for promoting safe boating habits and reducing the risk of accidents.

When considering the other options, those over 16 or 18 years of age suggest an incorrect assumption about the minimum age requirement or imply that the PCOC is not necessary until reaching those ages. The answer related to adult supervision also misrepresents the law since supervision doesn't negate the need for the card when the vessel's horsepower exceeds the threshold, making it essential for all young operators to be properly trained and certified.
