Are you looking for white girls or asian?
Take whatever I tell you with a grain of salt as I'm no fs expert but since you're in North York, the spas at 4801 Keele (by Steeles) such as Seduction would be an option if you're looking for hot young white (and some asian) girls. My understanding is you'll be looking at around $250 all-in.
If you're looking for young asian girls and don't mind driving to Richmond Hill, you can try VIP or QQ. There's also Moon Dreams by Yonge/Clark. There's tons of reviews on these places. I suspect you would be looking at around $140-160.
There's also lots of SPs, either independent or via agency, that you can try out.
Maybe some fs guys can chime in.
