With regard to the VIN, I think if you look at a plain definition of the wording used, it refers to a “number”. Normally in the course of using a VIN, it's an 18-digit number. But when you look at provincial licence plates, they have numbers and letters. So I think even with just a straight interpretation of this definition, it would exclude provincial licence plates.
