We all know that for skin protection, you prefer darker tints, but do you know that the province of Ontario has a specific law regarding visibility percentage? In Ontario, legality is based on how much light passes through your glass, not how dark it looks from the outside. It means the wrong tint can lead to traffic stops, fines, and costly removal, while the right tint delivers heat rejection, UV protection, and comfort without legal trouble. Before choosing a shade for your car in Toronto, Markham, or anywhere in the GTA, call us right now for a free consultation and find out what is appropriate for you. But here, we’ll explain it to you in detail.
What is the window tint?
Window tint is a thin film you can apply inside your window, and its primary purpose is to control how much light, heat, and UV radiation pass through. Window tints can protect your skin and car interior, and also provide privacy so no one can see inside the vehicle. The percentage of window tint indicates how much sunlight can pass through the window and is an indication of visibility. The key factor is VLT (Visible Light Transmission), which determines how dark or light the tint appears and whether it is legal to use on your vehicle.

What is the darkest tint you can get legally in Ontario?

The darkest tint you can have in the province of Ontario is 30 percent VLT for the left and right-front windows. However, when we speak of the back windows, there is no limitation, and you can have the darkest tint, which is 5% on both sides. This darkness will keep light out, and nothing will be visible from the outside.
Window Tint Rules for Toronto, Markham, and the GTA
Window tint laws are essential across all parts of the Province of Ontario, which means the same rules apply whether you’re driving in Toronto, Markham, or anywhere else in the Greater Toronto Area (GTA). The law focuses on driver visibility, primarily through the front side windows and the windshield. For the front windows, since the driver should check the mirrors, the rules require a VLT of over 30%. However, these limitations are not mentioned for the back.
What Happens If Your Window Tint Is Too Dark in the GTA?
In case you violate the legal window tint rules, police can stop the vehicle in Toronto, Markham, and surrounding areas. If the police believe the window tint can reduce a driver’s visibility and cause problems to other drivers, they can stop the vehicle and make you remove the tint. Moreover, this is not the end; the police can, at any time, without any test, give you a ticket and impose a fine wherever you are.
Police Fines for Illegal Window Tint in Toronto
There is a strict rule regarding illegal window tint all over Toronto, and if police believe you have violated that rule, especially for the front window, you will be fined between $85 and $500 in Ontario. The police do not need any high-tech device; if they are convinced that the visibility is compromised, they can pull you over and give a ticket. Keep in mind, this ticket will not affect the insurance fee at all.
