Canada window tint laws are different in each province, and this article provides all relevant information about window tinting laws in Ontario.
Ontario window tint laws overview:
- Windshield: No tint recommended.
- Front side windows: No tint recommended.
- Back side windows: Any tint darkness can be used.
- Rear window: Any tint darkness can be used.
Ontario laws do not expressly specify whether front window tinting is legal or not. According to Ontario Highway Safety Act (linked below), you may not drive a vehicle if:
[…] any window to the direct left or right of the driver’s seat […] substantially obscures the interior of the motor vehicle when viewed from outside the motor vehicle.
We strongly suggest not installing window tint on windshield or front side windows, as any percentage could technically result in a fine. It’s up to an individual police officer to determine whether your tint “substantially” obscures vision in your car.
New Ontario vehicle inspection regulations state that cars manufactured after January 1st, 2017 may not have any aftermarket window tint applied to the windshield. OEM (Original Equipment Manufacturer) or factory-made cars can have 70% VLT (30% opacity/light block), and tinting may not extend more than 75mm from top of windshield.
Ontario law does not restrict tinting and darkness on your back side windows and rear window. Ontario’s traffic law also requires having left and right external rear view mirrors in case rear window is tinted (sec. 74.2).
Other Ontario tint laws:
- Reflective tint: Not allowed.
- Side mirrors: Required if rear window is tinted.
- Medical exemptions: None.
- Certificate requirements: None.
- Tint sticker requirements: None.
Penalties for unlawful car window tint in Ontario result in a $85 – $500 fine, and there may be additional surcharges and fees involved.
