Ontario tint laws do not allow tinting front windshield or front side windows. Back side windows and rear windshield may have any darkness.
No tint allowed
Front Side Windows
No tint recommended
Back Side Windows
Ontario restricts windshield tinting to top 75 millimeters (3″) with 70% VLT, but only if windows were manufactured as such. Aftermarket tint is not allowed.
Ontario’s vehicle inspection regulations state that vehicles will pass if front side windows have over 70% VLT. However, Ontario tint laws are very vague on this, and state that these windows must not “substantially obscure the interior of the motor vehicle when viewed from outside the motor vehicle“. Tinting front side windows is not explicitly prohibited, therefore 70% VLT should be within legal limits.
There are no restrictions for tinting windows behind driver.
