Vaughan is loaded with its fair share of semi-legits. All along Jane Street, Weston and highway 7. And Keele south of Steeles, is a whore's f-fest.
Hell, there are 5 within walking distance of Canada's Wonderland.
As Vaughan has a large percentage of Europeans (mostly Italians), you will be hard pressed to find any non-Asian spas. I guess there is a stigma to have someone who resembles a mother, wife or sister, playing with a clank.
I just went to Ellagence. Nice spot, clean and fairly priced. But all Asians.
Good luck...
