Hello:
Thank you for your inquiry regarding window tinting.
You may not install any tinting film on the windows left and right of the driver. The primary concern is tinting the windshield or side glass may, during darkness or inclement weather, limit or restrict the operator's ability to see other highway users and objects.
Manufacturers are allowed to install factory tinted side glass with a 30% maximum tint. The tint must be built into the glass (it cannot be a film applied to the glass). Side glass must be marked AS-2 and windshields must be marked AS-1.
Alberta's Vehicle Equipment Regulation 322/2002 section 69(1) prohibits the installation of any tinting film or material to the windshield and the windows to the left and right of the driver. Section 72(2) requires a motor vehicle, should it have a tinted rear window, to have side mirrors on both the left and right side that give the driver a clear view of the roadway behind and on each side of the motor vehicle.
We don't recommend adding window film to the rear glass when children frequently ride in the vehicle; the tinting film can change the breaking properties of the safety glass; increasing the possibility of injury. To view the Vehicle Equipment Regulation, please go to the following web link:
