These should be good to get you started.

I listed some TER sealed sites but there are MANY others that have great service/girls.  Not sure what the rules are with listing that info but a big hint would be for you to look around in a forum at merb.ca  Montreal seems to be 2nd to none when it comes to beautiful girls/ service/and price.  You are a lucky man to be able to visit there.  Hopefully I will be as luck someday.  You can thank me later for the links!
