Before tinting your car windows in Quebec, one question always comes up: how dark can you go? The law regulates tint for safety reasons, and the rules differ by window. Here’s the essentials, in plain terms.
Front side windows
These are the most regulated. In Quebec, the front side windows (driver and passenger) must let through at least 70% of light. In other words, a film that blocks more than 30% of light isn’t compliant up front. It’s the most closely enforced rule.
The windshield
On the windshield, tint is only allowed on the top strip — roughly the first 15 centimeters at the top. The rest of the windshield must stay clear.
Rear windows
Good news: the rear side windows and the back window aren’t held to the same limit. You can apply a darker tint there, as long as the vehicle has both exterior mirrors (left and right). That’s where most clients darken the look.
Reflective films: avoid them
The rules also target overly reflective or mirrored films, which create glare. We favor a film that darkens without a mirror effect.
What if the tint isn’t compliant?
Non-compliant tint can lead to a fine and a requirement to remove the film. It’s worth starting off right with a compliant film — especially up front.
