Alberta Window Tint Laws 2026: What's Legal on Each Window

Quick answer: Alberta does not allow tinting film on the windshield or on the windows to the left and right of the driver unless the driver holds an exemption permit from the Government of Alberta. That restriction is about any tinting material on those windows, not a particular darkness: a light or 'clear' ceramic film on the front side windows still needs the permit.

Key Takeaways

Alberta does not allow tinting film on the windshield or on the windows to the left and right of the driver unless the driver holds an exemption permit from the Government of Alberta.
That restriction is about any tinting material on those windows, not a particular darkness: a light or 'clear' ceramic film on the front side windows still needs the permit.
The exemption is a $55 permit for approved medical conditions (skin cancer, bullous pemphigus); the only film it allows is clear UV film with a combined visible light transmittance of 50% or more.
The rear side windows and the rear window are outside the restriction, so that is where tint for privacy and heat control goes.

Reviewed 25 September 2026 against alberta.ca

"How dark can I tint my windows in Calgary?" is the question we hear most about window tinting. In Alberta the answer depends on the window. The Government of Alberta says tinting material "is not allowed to be attached to the windshield and the windows to the left and right of the driver unless you get an exemption" (alberta.ca). The rear side windows and rear window are outside that restriction.

Correction

An earlier version of this guide said Alberta sets no rule for the front windows and that film of about 50% VLT there was accepted. That was wrong: film on the front side windows needs a Government of Alberta exemption permit, and even then only clear UV film of 50% or more combined VLT is allowed.

Alberta Tint Law, Window by Window

Window	Without a permit	With an exemption permit
Windshield	No tinting material	Only as the permit allows
Front side windows (left and right of the driver)	No tinting material, however light	Clear UV film only, 50%+ combined VLT
Rear side windows	Outside the restriction	Outside the restriction
Rear window	Outside the restriction	Outside the restriction

The Exemption Permit in Brief

Who: drivers with a valid Alberta licence and a physician's note for an approved condition: diagnosed or recurrent skin cancer (melanoma, basal or squamous cell) or diagnosed bullous pemphigus. Photophobia, migraine, cataracts and rosacea are not considered. Passenger requests may not be supported, since passengers can sit in the back.
How: email the request to the permitting and exemptions office listed on alberta.ca; review can take several weeks.
Cost: a $55 permit fee.
Film: clear ultraviolet film with a combined visible light transmittance of 50% or more; existing film below 50% must be replaced.
Carry it: the permit must be kept in the vehicle.

The full process is in our guide to getting a window tint exemption in Alberta.

Understanding VLT

Visible light transmittance (VLT) is the percentage of visible light that passes through the glass and film together. Higher is lighter. In Alberta, VLT is a choice you make for the rear glass, and a limit for permit holders on the front side windows (50% or more combined).

VLT	What it looks like	Where it fits in Alberta
50% and up	Light; barely changes the look	Rear glass; the only range allowed on the front side windows under a permit (clear UV film)
35%	Medium; silhouettes visible in daylight	Rear glass
20%	Dark; little visible from outside by day	Rear glass
5%	"Limo"; very little visible from outside	Rear glass

Getting the Most From Legal Tint

Darkness and heat rejection are different properties. A ceramic film rejects far more infrared heat than a dyed film of the same darkness, so the rear glass can do a lot of the cooling work without going to limo darkness. Compare ceramic, carbon and dyed films before you choose, and see how much privacy each darkness gives. The windshield is laminated glass that already blocks most UV. If you drive into BC, its rules differ in the details; see tint rules in Canada.

Frequently Asked Questions

On the rear side windows and the rear window, yes. On the windshield and the windows to the left and right of the driver, tinting material is not allowed unless you hold an exemption permit from the Government of Alberta.

There is no legal percentage for aftermarket film on the front side windows without an exemption, because the rule prohibits tinting material there altogether. With an approved medical exemption permit, the film must be clear UV film with a combined visible light transmittance of 50% or more.

Apply to the Government of Alberta by email with a physician's note; approved conditions are skin cancer (diagnosed or recurrent melanoma, basal or squamous cell) and bullous pemphigus. The review can take several weeks, an approved permit costs $55, only clear UV film of 50% or more combined VLT is allowed, and the permit must be carried in the vehicle.

No. Tinting material is not allowed on the windshield in Alberta unless you hold an exemption. Laminated windshield glass already blocks most UV.

No. 'Ceramic' describes the film technology, not the darkness; ceramic film comes in the full range of shades. Its advantage is heat rejection: a ceramic film rejects far more infrared heat than a dyed film of the same darkness, which is what makes it worth choosing for the rear glass.
