79 Dodge St Regis with 340 engine

If its OK with customs, I could drive the car to Ontario. Not sure if I gotta pay duties or fees to sell a car in Canada ?

I took the Greyhound bus from Toronto to Detroit in the past, its a 6 hour ride but gets me back to my home state.

London, Windsor, Hamilton, maybe Niagara Falls. Ottawa is too far. Just drop me off at a bus station and I go from there.

But I gotta check with customs first what is allowed and I would need a non refundable deposit to pay for the fuel which would be costly, it gets 10 to 12 mpg
