About using a VHF radio in Canada … Transport Canada has a list of requirements for foreign recreational boaters in Canadian waters. Among them it states, "Currently, all VHF radio operators are required to have a Restricted Operator's Certificate (ROC) with maritime qualifications. Canada recognizes the American Certificate." It should be noted that it is not required for Americans to use one in American waters, so you probably don't have one. You can obtain a certificate through both United States Power Squadrons and Canadian Power and Sail Squadrons courses.
