Thanks guys for the input. I did bring my last ranger home from the US 10 years ago but figured it was much differently commercially. Now after researching, it appears as though it will be the same process. Stop at US customs with title, bill of sale and then stop at Canadian Customs for importation purposes. Through all the literature I still can't find definitive info saying I'll pay hst at the border or not. I've heard many people on both sides when Importing.
On the bill of sale I will have my company name as the purchaser with my own personal name as the co purchaser. This is the same way it's done when buying a truck under your company name.
I do get your suggestion for separate bill of sales however I fully suspect a single bill of sale with itemized pricing for the boat, engine and trailer should do the same thing. One person told me that the engine isn't taxed. Has anyone else heard this.
Any follow up points or thoughts are welcomed.
Thanks again.
