Just a follow-up remark:

You mentioned that you still owe money for the vehicle. I presume that is in the form of a loan from a bank or from a vehicle financing company. If that is the case, then that has nothing whatsoever to do with your ownership and registration of the vehicle.

The vehicle is most probably registered in your name (check the document), so far as your loan is concerned, that is a civil matter between you and the organization that loaned you the money - it has nothing whatsoever to do with your ownership of the vehicle. It is probable that the organization that loaned you the money has registered a lien on the motor vehicle with your provincial government - in other words, there is a note on the file recording your ownership of the vehicle that indicates that the title cannot be transferred to anyone else until the lien is removed - but that is likely of no interest to anyone at a border crossing point.

However - if you still do owe money on the vehicle, you might want to check the fine print of your loan agreement. It is quite possible that there is a clause in the loan agreement that states that you cannot take the vehicle out of the United States or Canada without prior permission of the organization that loaned you the money. This is because that organization would have a hard time enforcing their lien outside of the USA or Canada. But, again, that is an entirely civil matter.
