Wondering how dark you can tint your windows? Want to know if having tinted windows will raise your insurance rates? Keep reading to learn about car window tint rules and how they affect your insurance.
Does Window Tint Affect Car Insurance in Ontario?
As long as your tinting is Ontario-legal, thereβs no blanket, across-the-board increase in premiums. Premiums and coverage terms are outlined in insurance rules filed with the Financial Services Regulatory Authority of Ontario (FSRA). No general filed rule automatically raises premiums solely because windows are tinted.
That said, Ontarioβs basic auto insurance contract, also known as OAP 1, requires you to let your insurer or broker know when you modify your vehicle in ways that may affect the price or insurability of your coverage.
Does Window Tint Affect Collision Claims?
Tinting wonβt automatically affect whether an insurer will pay out on a claim. However, the insurer can examine whether illegal window tint contributed to the collision. A policy breach may affect a claim only as permitted by the policy and law, such as if you lied about tinting your windows when asked if your car was modified.
What Is the Law About Window Tinting in Ontario?
Section 73 of the Highway Traffic Act says you canβt cover your windows with materials that interfere with the driverβs view through the windshield or front side windows, or that substantially obscure a view into the vehicle through those windows.
Is a 5% Tint Illegal in Ontario?
Contrary to popular belief, the Highway Traffic Act doesnβt define what constitutes a legal window tint in Ontario, so thereβs no mention of 5%, 20%, or 50%. It leaves that up to an officerβs judgment. If youβre not sure how dark is too dark for Ontarioβs front-side windows, MyChoice recommends speaking with an auto glass shop.
- 50% tint lets through about half the visible light. This is not an official legal category in Ontario. On a vehicle built on or after January 1, 2017, the windows beside the driver would be too dark; they must have at least 70% combined VLT to pass a safety inspection.
- 20% tint is much darker and can make it hard to see inside the vehicle. It does not meet the 70% front-side-window requirement for 2017 or newer vehicles. It may be used on rear side windows if it does not block the driverβs required view.
If your car has working mirrors that offer a clear view of the road behind your vehicle, Ontario allows darker shades of tint on your back windows and an added privacy screen for the back of an SUV.

Window Tinting Rules and Safety Inspections in Ontario
The rules are clearer during an Ontario vehicle safety inspection. For cars and trucks made on or after January 1, 2017, the visible light transmission through the front side windows canβt be less than 70%. Windshield tint also canβt extend more than 75 mm from the top or beyond the AS line.
What Is the Penalty for Illegal Window Tint in Ontario?
The base ticket is an $85 fine for a section 73 offence under Ontarioβs Highway Traffic Act. Youβll pay more once court costs and victim surcharges are included.
Will I Fail Inspection for Window Tint in Ontario?

How Do They Test Window Tint at an Ontario Safety Inspection?
Ontario safety inspection stations measure the percentage of visible light coming through your tinted windows.
Can I Use a Tinting Calculator or Light-Meter App on My Phone?
The VLT of windows with aftermarket tint is a combination of the glass VLT and the tinting material. Many online calculators donβt account for this. Some offer a chart of common glass types and their corresponding VLTs, but itβs far from perfect.
Apps that use your phoneβs built-in light meter are even less accurate. Screen size, sensor location, how you hold your phone, and external lighting all come into play. If an officer pulls you over or your vehicle is inspected, theyβll use a tinting meter most likely.
What Colour Tint Is Illegal in Ontario?
Ontarioβs Highway Traffic Act prohibits coloured material on the windshield or windows directly beside the driver that substantially obscures the vehicleβs interior. The tint must comply with the visibility rules and any applicable safety-inspection standard.
Bottom Line
Ontarioβs window-tint rules distinguish the driverβs forward view, front-side-window inspection standards and rear-window visibility. Check the current legal and inspection requirements before applying film, and tell your insurer about vehicle modifications when the policy requires disclosure.
