A pleasure craft licence provides a unique identification number - commonly referred to as the "licence number" - that must be displayed on recreational vessels. A licence or registration is mandatory for all pleasure craft equipped with motors of 10 horsepower (7.5 kilowatts) or more, including personal watercraft, which are principally maintained or operated in Canada. A licence does not provide proof of ownership. Separate ownership documents should be carried on the vessel at all times.
