I live in the america and I got a parking ticket in Toronto Canada when I was on vacation but forgot to pay it its been a while and I'm going back for vacation to Toronto. when I cross the border to Canada will it be a problem ? will they check my plates?

 

I have heard that certain states have agreements with Canadian cities on sharing of ticket information so it could affect you registering/renewing your plate in the USA too.
I'm not 100% certain, but i don't believe that a city parking fine would be shared with Canada border services. So i don't think you'll have an issue actually entering Canada.

 

A little more reading and this may only apply to traffic violations not parking fines.

 

just call them up and pay the ticket?
