Got mine done at CanCare using 20% Madico all the way around (although 15% light gets thru). As long as you sign a waiver they'll do whatever you want. The legal limit is defined as 'vague' for the driver and passenger side windows, but 35% seems to be the accepted 'legal' limit. As far as the back side and rear window are concerned, you can get any % you want. Cops only care about the driver & passenger side front windows.
