Not so much near Rosemont, but lower plateau/closer to downtown there's Massage8080 that has a place at St Denis and a more private one on Crescent. Text em to book, they're pretty good! Not really a fs place though, you do get HE and YMMV.
There are a couple more scattered throughout the Montreal area to be honest, if you walk around and see a place all curtained up but with an Open sign chances are its an MP and 8/10 times its an AMP. Consult the merb board too if you want more concrete locations!
