If someone purchases a boat in the U.S. and chooses to import it into Canada, if it's newer than 2018, it will be subject to the luxury tax at the point of entry into Canada if they choose to register it. That's not necessarily what the case would be with boats. They can float the boat across. They can come through the Great Lakes. They can choose to enter Canada, stay up to one year and then leave again, which a lot of boaters do. They go back stateside and never pay the tax on the boat.
