Speeding

I have a speeding ticket in Canada?

I'm from Massachusetts and has a speeding ticket for going a bit over the speed limit right after crossing the border from NY to Quebec. I paid the fine so that I do not have to worry about it, but do you know if and Mass Québec has a reciprocal agreement to exchange information with the RMV state and therefore my insurance company?

I do not think they do, and if there was a major infraction, provided there is paid the ticket, you should be fine. (I've had entries from Canada and I've never seen anything in my insurance.)
