As my first post on lyla, I would like to recommend some of the few great agencies we have in Montreal. Here are my favorites in order of importance (to me). All are very well reviewed.
I would also like to mention that you should stay away from Backpage especially as its way too full of B&S here in Montreal.
Enjoy!
