Windsor MPs - not great
Was in Windsor a fair bit this summer and did some investigative work.
I only found one place that did extras - I think it's called Holistic?, on Ouellette. It's by another MP, and a dry cleaning place. I cannot remember the nearest intersection but it is past the downtown strip of bars & the Masonic Temple, closer to Tecumseh Rd. Anyway, it's very expensive. About $40 for a massage; almost $100 for the girl to be nude; and $50 for the release. Even then, not every girl will provide a release at this place.
It's much better to use the independent escorts: it's legal in Windsor, you have a choice over your "attendant", and a decent price. Check out this site for more info & reviews:
