A friend who gets a lot of parking tickets once advised me not to pay it immediately. Rather, one should wait for the administrative reminder from the City of Montreal. If you don't get the reminder, that means the city has lost track of your ticket. Me: 1. Mayor Tremblay: 0.
Of course, what if the administrative reminder from the city never reaches you because of some mixup at Canada Post. The city will assume you received it. And if you don't pay, it will assume you want to go to court. The next letter you get will be an appointment notification letter. At that point, you're screwed because you'll be on the hook for court fees too -- even if you decide to pay the original fine.
Fortunately, you can now check the status of your parking ticket at the city's Web site. Wait a week or two and then check to see if your ticket is in the system.
