Tinted Windows in Quebec still cause a lot of confusion. Some people talk about percentages, others about police tolerance, and some even swear that “35% is legal.” The reality is simpler — and stricter — than that.
In this article, we break it down without ambiguity, with clear rules based on the law and on what is actually enforced on the road. The goal: help you avoid a ticket, a notice of non-compliance, or a failed inspection.
Why the law regulates tinted windows
Tinted window regulations pursue two specific objectives:
- Ensure sufficient visibility for the driver, especially at night, in the rain, or in winter conditions.
- Allow police officers to see inside the vehicle during traffic stops, for safety reasons.
This is not about aesthetics, but about road safety. That’s why certain rules are non-negotiable.
Windshield: very strict rules, no exceptions
Tinting prohibited on the entire surface
In Quebec, any tinted film applied to the windshield is illegal, even if it is very light.
Sun strip allowed
There is only one exception:
- A tinted strip at the top of the windshield
- Maximum width of approximately 15 cm (6 inches)
- Must not interfere with the driver’s field of vision
- Must not extend below the AS-1 line
Anything beyond that strip = immediate violation.
Front side windows (driver and passenger): the 70% rule
This is the most critical — and most misunderstood — point for drivers.
In Quebec, front side windows must allow at least 70% of light transmission.
A film may be added only if the final light transmission remains at or above that threshold.
Result:
- A film that is too dark makes the vehicle non-compliant
- Even a “light” film can bring the total below 70%
- The percentage advertised by the installer does not guarantee compliance
That’s why many drivers receive tickets even though they believe they are within the law.
Rear side windows and rear windshield: much more permissive
Here, the regulation is straightforward and more favorable to drivers.
- Tinting allowed with no percentage limit
- Very dark films permitted
- Exterior side mirrors required (left and right)
As long as the driver can see to the rear using the side mirrors, rear tint is legal.
That’s why many SUVs and family vehicles come with very dark rear windows.
Factory tinted windows
Always legal
Even when they appear dark.
Why?
- They comply with manufacturer standards
- They meet Transport Canada requirements
The law only targets films added after purchase, not factory-installed tinted glass.
Fines and possible consequences
If your vehicle is not compliant:
- Fine typically between $200 and $300
- Notice of non-compliance
- Obligation to remove the film
- Repeated stops until the issue is corrected
In some cases, the vehicle may even be prohibited from being driven until corrected.
Mechanical inspection: a common failure point
During an inspection:
- The windshield is systematically checked
- Front windows are evaluated without exception
- Non-compliant film = automatic failure
Many drivers must remove the film, redo the inspection, and sometimes re-tint only the rear windows. An avoidable double expense.
Aftermarket tinting: the importance of the right installer
A reputable professional:
- Explains what is legal and what is not
- Refuses to tint front windows beyond legal limits
- Offers compliant solutions (UV protection, heat reduction, rear windows only)
Specialists like Dr Tint work with this reality in mind: delivering the benefits of tinting without putting customers at risk.
Common myths to forget for good
- “Anything is allowed as long as it’s not too dark.”
- “I’ve never gotten a ticket, so it’s fine.”
- “Inspection is just a formality.”
The law doesn’t work on perception. It works on compliance.
How to stay 100% legal with tinted windows
- Keep front windows without added film unless they remain at or above 70%
- Use only the permitted windshield strip
- Freely tint the rear windows
- Ensure exterior side mirrors are fully functional
Simple. Clear. Effective.
