This is what you need in your boat at all times according to:
Licensing and registration
All pleasure craft, which are principally maintained and operated in Canada and powered by one or more motors adding up to 7.5 kW (10 hp) or more must be either licensed or registered.
To get a Pleasure Craft Licence, Canadians must complete an application form and mail it along with proof of vessel ownership and a copy of a valid piece of personal identification to the Pleasure Craft Licensing Centre.
