Car window tinting is a popular modification for many vehicle owners seeking to enhance privacy, reduce glare, and protect their car’s interior from harmful UV rays. However, each province in Canada has its own set of regulations governing window tinting, and Ontario is no exception. In this article, we will explore the requirements and laws regarding car window tints in Ontario, Canada, to help car owners make informed decisions while staying compliant with the law.

Legal Tint Levels in Ontario

Ontario has strict guidelines concerning the darkness of window tints, and these regulations apply to all passenger vehicles, including cars, vans, and SUVs. As of my knowledge cutoff in September 2021, the permitted darkness levels for car window tints in Ontario are as follows:

Windshield: Non-reflective tint is allowed only along the top 15 centimeters (approximately 6 inches) of the windshield.

Front Side Windows: Tinting is permitted, but it must allow at least 70% of light transmission through the glass.

Rear Side Windows and Rear Window: Tinting is allowed with no specified minimum light transmission requirement.

These rules are essential to ensure that drivers have clear visibility on the road, especially during low-light conditions and adverse weather.

Medical Exemptions

While Ontario’s window tint laws are generally stringent, there are provisions for individuals with medical conditions that necessitate additional sun protection. In such cases, individuals can apply for a medical exemption from the tinting regulations.

For a medical exemption to be considered, a licensed medical practitioner must provide a written certificate detailing the individual’s specific medical condition and the reasons why tinting is necessary. The exemption certificate must be carried in the vehicle at all times, and the tint must still comply with certain light transmission standards.

Reflective Tints

Ontario prohibits the use of reflective window tints on vehicles. Reflective tints are those that mirror the surrounding environment and can be a safety hazard for other drivers on the road, as they can cause glare. Using such tints can lead to fines and the possibility of having to remove the tint to comply with the law.

Enforcement and Penalties

Ontario authorities take window tinting laws seriously, and law enforcement officers regularly conduct checks to ensure compliance. If a driver is found to have windows that do not meet the legal requirements, they may face penalties, which can include fines and/or an order to remove the tinting material.

Fines for violating window tint laws can vary, and they often depend on the severity of the violation. Additionally, multiple offenses can lead to increased fines and further legal consequences.

Importance of Professional Installation

To ensure compliance with Ontario’s window tinting laws, it is crucial to have window tints professionally installed by trained and experienced technicians. A reputable installer will be familiar with the local regulations and ensure that the tinting material used meets the legal requirements.

Improperly installed window tints may not only result in legal issues but can also cause bubbling, peeling, or reduced visibility, compromising the safety of the driver and passengers.


Car window tinting can be a valuable addition to any vehicle, providing numerous benefits, including increased privacy and protection from harmful UV rays. However, it is essential for car owners in Ontario, Canada, to be aware of and abide by the specific laws and requirements regarding window tints.

By following the permitted tint levels, avoiding reflective tints, and considering medical exemptions when necessary, car owners can enjoy the benefits of window tinting while staying compliant with the law and ensuring the safety of themselves and others on the road. Always consult with a professional window tinting service to ensure that your vehicle’s window tints meet all legal requirements and provide optimal performance.
