If you have a ship's radio license and Canadian operator's license, certainly no issues. I belive some parts of canada use "international" or "Canadian" settings--in the US--"US" channel line up is used.
In the US, and I believe in Canada, the station license is not required for yacht operation--unless crossing into international or "foreign" waters. There is reciprocity with Canada, but a US boat is required to have at least the Restricted Operators Permit. If you have the Canadian Marine operator's permit, that is the equivilant, it would be accepted---but I doubt that i would be asked for except by a FCC investigator--and they seem to leave Marine VHF radio pretty much alone.
With multiple trips to Canada, and interaction with Canadian CG (mostly social), we were never asked for any radio documents, even though we did have a US Ship's license, (since we operated in many foreign countries in those vessels).
With Ham Radio, there is full reciprocity, but US Hams have to add the suffex
of the Canadian region.
