35% is the legal limit on the front door windows of any vehicle in Ontario. You can put 20% on rear windows, and as dark as you want on the back window. I went with 35% all-around on my stang, as it's interior is dark to begin with, and night time, it's hard to see into my interior. I had 20% all-around on my focus, and never ran into problems...I think that's because it was a black car, and the tint was the same colour and darkness all the way around...
