Check out http://merb.ca/
You don't have to join the website to look at it. However, membership is free. It has a lot of reviews on many girls in most agencies in Montreal. By the way, Outcall to your hotel room is legal in Canada. Going to an incall place is not.
If you join, you can do searches for particular agencies or girls, just like massageplanet. There are tons of reviews for Devilish girls. Most give GFE service.
I recommend you looking at the website before going. It will save you alot of headache and money.
By the way, Devilish raised their rates from $160 to $180 a couple of months ago. Candy's delight followed suit. XXXTASE and Girls of Fire still charge $160. Also, check out JDM, or Jardins de Madison during the day shift. They charge $140 per hour. They are a hit and miss, but the owner, Jacques, gets some real winners. You have to be discrimatory with him. All of his girls give great service.
The recommended agencies are XXXTASE, Devilish, Eleganza, Girls of Fire, Candy's Delight, Excentrix (which is an affliate of http://venusxxx.ca), Satin Dreamz, and JDM. Bailey of Chocolate Delights, who is of Greek decent, is another recommended hottie.
Also, I recommend Eleganza and joining the Eleganza website before heading up. Eleganza has some very classy, pretty and accomodating ladies. If you are a member of the site, they have multi-hour discounts. Their website is http://www.eleganzaescorts.com
The owner, John, is a busy guy, but he will help you in trying to get the girl you want.
Montreal is a playground as long as you stick to the recommended agencies on the merb website.
Also, there is a competing website called http://merc.ca/
There is also a new website called http://halthejohn.com/
It is run by a hobbyist who is very active. He broke off from merb and started his own website.
By the way, Toronto has TERB.CA, and Vancouver has PERB.CA.
Hobbying is very active in Canada, and it is better than here, because it is legal, at least in the outcall venue. And girls are typically GFE, at least in Montreal. I never been to Toronto, so I cannot tell you how Toronto compares. But the women in Montreal are very service oriented and most do not hustle.
