Quebec Window Tint Laws: Complete Guide

Quebec has some of the strictest front window tint rules in North America. Under the Regulation respecting safety standards for road vehicles (CQLR c. C-24.2, r. 32), made under the Highway Safety Code, the windows beside the driver must let in at least 70% of light. On most cars, that leaves no room for any film. The rear side windows and rear window are a different story: Quebec sets no darkness limit on them.

Key Takeaways at a Glance

Front side windows

Must let in at least 70% of light, measured with a photometer

Windshield

Only a strip no more than 15 cm (about 6 in) at the top. Nothing else may be applied or sprayed on the windshield

Rear side and rear windows

Not subject to Quebec's tint rules, so any darkness is allowed

SUVs, vans, and trucks

Same window rules as cars. Fines are higher for heavy vehicles

Medical exemptions

The SAAQ's tint guidance does not provide one

Penalties

$154 to $274 for passenger vehicles, plus a possible inspection order

Quebec’s rules follow the window, not the vehicle. A minivan’s front doors face the same 70% test as a sedan’s.

Windshield tint rules and the 15 cm strip​

Many US states let you tint down to the AS-1 line, a small mark etched near the top of the windshield. Quebec doesn’t use that mark. The SAAQ allows a strip no more than 15 cm (roughly 6 inches) wide along the top of the windshield, and that’s it.

No other material or substance may be applied or sprayed on the windshield, so clear or UV films below the strip are not allowed either.

Tint allowed Clear glass No film, tint or spray, including clear or UV film Top edge of windshield Max 15 cm about 6 in AS-1 line varies by vehicle
Legal tint strip Over the limit if tinted to AS-1 Must stay clear

Reflectivity and Color Restrictions​

The SAAQ’s rules are built around one test: how much light passes through the front side windows. Its guidance does not set a separate reflectivity percentage or list banned colors. In practice, a mirrored or coloured film on the front windows would almost certainly fail the 70% reading, and the windshield can’t take any film below the top strip.

Understanding VLT

VLT (visible light transmission) is the share of visible light that passes through a window. Quebec’s 70% rule means at least 70% of light must get through the front-side windows. Higher numbers are lighter; lower numbers are darker.

  • Your factory glass counts. Original windows are already slightly tinted. According to the SAAQ, front-side windows generally let in about 75% of light, and adding any film, even a transparent one, cuts roughly another 5%. That lands right at 70%, which is why the SAAQ says that in this situation no film or other darkening substance may be added.
  • How police measure. Officers take a photometer reading of the installed front side windows, so the result reflects glass and film together.
  • Heat without darkness. Ceramic and infrared-rejecting films are designed to cut heat while staying light, but on the front windows of most vehicles, even these won’t leave you above 70%. Have the glass metered before buying anything.

Certification, Stickers, and Inspection

Film certification and stickers

The SAAQ's guidance does not call for film certification or a compliance sticker.

Using a professional shop doesn't protect you

The SAAQ's guidance does not call for film certification or a compliance sticker.

Buying used

If you buy a used vehicle with tinted front windows, making sure they meet the standard becomes your responsibility.

Inspection orders

There's no routine tint inspection, but police can issue a notice requiring you to take the vehicle to a road vehicle inspection agent to have the front side windows checked. See Penalties below for what happens next.

Medical Exemptions

The SAAQ’s tinted window guidance does not include a medical exemption, and it applies the 70% front window rule without exceptions.

If you have a condition that makes you sensitive to light, talk to the SAAQ before installing any film.

Rear side and rear windows can be tinted as dark as you like, which may help with sun exposure for passengers.

Penalties

Fines depend on who is charged and the type of vehicle.

Situation

Fine

Front side windows let in less than 70% (driver or owner of a passenger vehicle)

$154 to $274

Same violation, driver of a heavy vehicle (GVWR 4,500 kg or more)

$125 to $344

Same violation, owner of a heavy vehicle

$249 to $525

Failing to take the vehicle for an ordered inspection

$438 to $865

Driving after the vehicle is taken off the road for uncorrected tint

$154 to $274 for each failure to comply

How an inspection order works

1

If an officer issues a notice for inspection

You must bring the vehicle to a road vehicle inspection agent.

2

If the agent finds the front windows non-compliant

You get 48 hours to fix them, after which the agent checks again. If the tint still isn’t corrected, the vehicle is no longer authorized for road use.

3

If the tint still isn't corrected

The vehicle is no longer authorized for road use.

Choosing Legal Film in Quebec​

Maximum legal privacy

Go as dark as you want on the rear side windows and rear window, and leave the front side windows as they came from the factory.

Heat rejection

Rear windows can take any high-performance ceramic or IR film. For the front windows, ask an installer to meter the factory glass first. If it already reads close to 75%, you can't legally add film.

Windshield sun glare

A top strip no deeper than 15 cm is the only legal option.

FAQ

What is the darkest legal tint in Quebec?

On front-side windows, the glass and any film together must let in at least 70% of light. The rear side windows and rear window have no limit, so any darkness is legal there.

Only on the rear side windows and rear window. It is not legal on the front side windows or the windshield.

Often not. Factory front glass typically lets in about 75% of light, and the SAAQ says any film, even a clear one, reduces it by about 5%. If your glass starts at 75%, you may not be able to add film.

Only a strip at the top, no more than 15 cm (about 6 inches) wide. Nothing else may be applied or sprayed on the windshield.

For a passenger vehicle, $154 to $274. Heavy vehicle drivers face $125 to $344 and owners face $249 to $525. Ignoring an inspection notice costs $438 to $865.

No. The same window rules apply to cars, SUVs, vans, and pickups. Only the fines differ, and only for heavy vehicles with a GVWR of 4,500 kg or more.

The SAAQ’s tint guidance does not require one.

The SAAQ’s tint guidance does not provide a medical exemption. Contact the SAAQ directly if you have a medical concern.

Yes. The SAAQ says you can be fined and required to remove non-compliant film even if a specialized shop installed it.
