Try CanCare up at King St. by Northfield.
Or, grab a phone book, and call all the places to get quotes. I called like 10 places and some of them have sales or specials in the spring. I had mine done last year at Apple AutoGlass on Highland and Westmount for $150. I'm only a 2-door though. I would say stay away from Tint Shop, I'm not a big fan of them, plus they are pricey.
