Once you have your vessel registration, it will be time to mark it accordingly. The Canada Shipping Act of 2001 details that boats need to be labelled according to certain guidelines. You will have to mark the vessel with its name and port of registry on the exterior part of the hull in a way that makes both things easily visible and legible. In the case of commercial vessels, the name must be marked on each bow, and the port of registry and name must be marked on the stern. Remember that the information must always be clearly visible and permanently affixed in some manner.
