Up for you!
Suggest you to sell it in Montreal.
Here you can only sell it to people in Hull.
People living it Ottawa have to get it inspected (Ontario law), and with a car that old, the garage will find lots of problems. It's very possible that you will have to spend a lot of money to get all the problems fixed in order to get a license.
You do not have to do it in Quebec though. So you can sell with better price in the Quebec side.
