$20 for 15 minutes at Double Tree Spa (near Shephard and Brimley) right across from CIBC. You can't miss it, there is a big ass yellow sign right beside the railway bridge.
If you can show up before noon, Temptation Spa (near Eglinton and Danforth) and Apple Tree Spa (near Eglinton and Midland) have $20 for half hour. Honestly all three places look like a dump but you get what you pay for. The only time I went to Apple Tree, I got a pork chop MPA. If you visit Apple Tree website, they features a pork chop too argh. So the morale of the story is, you get what you pay for.
