Alberta Window Tint Laws: What You Need to Know
Before getting your windows tinted in Calgary, it’s important to understand Alberta’s window tinting regulations. Getting the wrong shade on the wrong window can result in a traffic ticket and the cost of having the tint removed. Here’s everything you need to know about what’s legal in Alberta.
Current Alberta Window Tint Regulations
Alberta’s window tinting laws are governed by the Vehicle Equipment Regulation (AR 122/2009) under the Traffic Safety Act. The regulations specify minimum Visible Light Transmission (VLT) requirements — the percentage of light that must pass through the glass.
Windshield
The windshield must allow a minimum of 70% VLT across its full area. Most factory windshields already sit around 70-75% VLT, so the only practical option for windshield tinting is a nearly clear film like 3M Crystalline or 3M Ceramic IR in the lightest shade. These films reject significant heat and 99% of UV rays while remaining within legal limits. Visit our windshield tinting page for more details.
Front Side Windows (Driver & Passenger)
Front side windows must allow a minimum of 50% VLT. This means you can apply a light tint, but nothing too dark. A 50% VLT film lets half the visible light through — it provides a subtle tinted look while remaining legal.
Rear Side Windows
There is no restriction on rear side window tinting in Alberta. You can go as dark as you like on the rear passenger windows, including full limo tint (5% VLT).
Rear Windshield
Like the rear side windows, there is no restriction on rear windshield tinting. Many drivers choose a darker shade for the back of the vehicle for privacy and heat rejection.
VLT Percentages Explained
VLT (Visible Light Transmission) measures the percentage of visible light that passes through your window. The lower the number, the darker the tint:
- 70% VLT — Nearly clear, barely noticeable. Legal for windshields.
- 50% VLT — Light tint, subtle appearance. Maximum darkness for front side windows in Alberta.
- 35% VLT — Medium tint, noticeable but you can still see through easily. Popular for rear windows.
- 20% VLT — Dark tint, significant privacy. Common choice for rear windows.
- 5% VLT — “Limo tint,” very dark. Only legal on rear windows in Alberta.
What Happens If Your Tint Is Too Dark?
If a Calgary police officer or peace officer determines your window tint is too dark on the windshield or front side windows, you can receive a fine. The typical penalty is a traffic ticket, and you may be required to remove the non-compliant tint and have your vehicle re-inspected.
The fine amount varies, but it’s not worth the hassle. Getting your tint done right the first time — within legal limits — saves you money and headaches.
Best Tint for Night Driving in Calgary
One of the most common concerns about window tinting is how it affects night driving visibility. The key is choosing the right VLT for each window position:
- Windshield: Stick with 70%+ VLT (nearly clear films like 3M Crystalline). These reject heat without reducing night visibility.
- Front side windows: A 50% VLT tint has minimal impact on night visibility. Most drivers find it comfortable even in Calgary’s dark winter evenings.
- Rear windows: Darker tints on rear windows don’t significantly affect driving since you primarily look through the windshield and front windows. Side mirrors compensate for reduced rear visibility.
How Dark Should You Go?
Our recommendation for Calgary drivers who want the best balance of appearance, heat rejection, and legal compliance:
- Front side windows: 50% VLT (maximum legal darkness)
- Rear side windows: 20-35% VLT (good privacy and heat rejection)
- Rear windshield: 20-35% VLT (matches the rear sides)
- Windshield: 3M Ceramic IR or Crystalline in 70%+ VLT for heat rejection without appearance change

Medical Exemptions
Alberta does allow darker front window tinting for medical reasons. If you have a documented medical condition that requires additional UV or light protection (such as lupus, photosensitivity, or certain skin conditions), you can apply for a medical exemption. You’ll need a letter from your physician, and the exemption document must be kept in the vehicle at all times.
Frequently Asked Questions About Alberta Tint Laws
Can I get a ticket for tinted windows at a vehicle inspection?
Yes. If your front side windows or windshield tint is below the legal VLT minimum, you will fail an Alberta vehicle inspection and need to have the tint removed before passing.
Do factory-tinted windows count toward the VLT limit?
Yes. The VLT measurement includes the glass itself. Most factory glass is around 70-80% VLT, so any aftermarket film you add reduces the total VLT further. Your installer should measure the combined VLT (glass + film) to ensure compliance.
Are tint laws enforced in Calgary?
Yes. Calgary Police Service and Alberta peace officers do enforce tint laws, particularly during traffic stops and vehicle inspections. They use a light meter to measure VLT on the spot.
