Can't speak to independents as I have seen them advertise  in that area but have yet to experience any for myself. I just wanted to caution you that in terms of agencies, that the last Asian agency in Montreal I heard of was busted by the RCMP for trafficking months ago. If I were in your shoes I would look at regular agencies that might have an asian person on their roster, and forget about incalls entirely.

Montrealers have no idea what a good Asian experience is.  You're already experiencing better in NY.  If you want Asians, go west.  LA is your spot.  Yiu'll just be wasting money in Montreal. Retreads who couldn't make it in NY, let alone LA or Seattle.
