PST on the Boat: You're supposed to self declare using this form:
https://www2.gov.bc.ca/assets/gov/ta...nce-return.pdf Licensing: This is a federal Transport Canada thing, required for all pleasure boats above 10HP. It's free, and has nothing to do with provincial taxes. This is where the Bill of Sale puts ownership of the boat into your name.
Registration: Usually only for BIG pleasure craft (IE Yachts) and commercial boats. There's a fee to register. You designate a port of registry and a name for your boat. I wouldn't bother with this for your boat.
