Very specific question, so I'll answer with a very candid response.
Been to TO 3 times, Montreal 2 times, Vancouver once in the last 3 years or so.
Niagra Falls - Sundowners strip club on Lundy Lane. One of the best strip clubs in North America. When the USD was strong, things were very cheap. PACKED on Friday and Sat nights. Not unusual to see tour buses unload tons of people into that joint. Very hot girls. Take outs are prohibitly expensive. Stick with going on the stages w/ the girls and/or private VIP dances.
Toronto -
Lots of AMPs if you're into Asians. There are a few caucasian MPs. These places congregate, i.e. you could find 6-7 on the same damn block. Which is good since you can easily hit every one of them until you find one you like. PM me if you want details and info. I'd rather not post details on this board. Basically spas, massages, and extras.
Vancouver -
The SC scene does not exist there but there are a lot of AMPs. Very clean and nice places with decent looking girls. I didn't like the general nightlife at Vancouver. (You can't f*** 24hrs a day, I gotta have other stuff to do.) Don't know of any causian services there.
Montreal -
I am biased towards french canadians in that I think a lot of them are very hot. 2 main sections:
Downtown:
St. Catherine's street. There are a good 10 places right on the street. Just walk down and you'll see huge neon signs all over. I prefer downtown danse. Hottest women IMO. Been to about 5 different ones in the downtown area. Remember to not settle for anything less than contact lap dance. DO NOT ACCEPT these stupid american 'AIR DANCES'. That's full of crap. You have free roam of your hands and it cost 10 CAD per dance. Don't let the doorman bully you into tipping more than what you want to tip. It's a friggin tip. Stay away from Gentlemen's something right next door. That place is utter crap with poor service and ugly girls. Stay away from private dances that are not in a private booth. Stay away from octopussy. That place is a rip off.
Cresent street / St Catherine street - Regular clubs and cafes to pick up regular girls. If you got some game, go here. Yes, it's touristy and you might meet other americans instead of locals but good place to pick up women.
Greater Montreal area:
This means you must have a car, good with a map, or have a GPS in your car. Otherwise just forget about exploring outside of the montreal area. These SCs are not like normal SCs. There are no rules. You can get anything for a price. I don't think I need to elaborate. PM for location to find these types of establishment. I was disappointed when I went last year around labor day as my favorite SC from the year before had closed. Girls are now scattered across several different SCs.
Incalls - Stay away. Despite what people say, you need to check the goods before you buy.
Outcalls - Never tried. Heard people have had good experience.
Since Cananda is no longer on my list of places to hit, I don't mind sharing the info.
