You're not getting my sense of humor are you?
The Vancouver dirty MP scene is largely Asian managed, and the girls working there are largely Asian. However, there are some which have a variety of non-Asian girls working. Like the above post, Atlantis and Bex are popular ones with several non-Asians working. Best to call them in advance, and tell them what you are looking for to schedule.
Your other option is to contact a non-Asian Escort Agency, like Carmen Fox, but then its no longer a "massage' per se, if that really matters to you. You can find tons of non-Asian companions and agencies on leolist in that case.
I think Vancouver sucks in General, worse than Toronto, but likely better than Edmonton (never been there myself). Whether you want to go to Seattle, where the $ is much stronger, costs are higher, and the Cops enforce this thing much more strictly, is entirely your call and I don't know if that is a wise decision. I can only say that Las Vegas is way better, but again you get what you pay for.
