Car Window Tint Laws by Province in Canada: What You Need to Know Before Tinting



When it comes to personalizing your ride, few upgrades are as popular—or practical-as—as car window tinting. It elevates your car’s aesthetic and offers real benefits like privacy, heat reduction, and UV protection. But before you rush to get your windows tinted, it’s crucial to understand the window tinting laws in Canada, because unlike the U.S., where regulations are set state by state, Canada handles things province by province, and they vary more than you might think.

Knowing your local tint laws can save you from fines, inspection fails, or even being forced to remove the tint altogether, whether you're in Mississauga, Brampton, or somewhere in between. In this article, we'll walk you through everything you need to know about Canadian window tint laws by province, explain what’s legal and what’s not, and give expert tips from the car real experts who live and breathe tinting every day.

Why Tint at All?

Before we dive into the laws, let’s talk briefly about why people get window tinting for vehicles in the first place.

  • Privacy & Security – Makes it harder for outsiders to see into your car.

  • Heat & UV Protection – Blocks harmful UV rays and reduces interior heat.

  • Style & Appearance – Enhances the sleek look of any car, truck, or SUV.

  • Glare Reduction – Cuts down on sunlight and headlight glare, improving visibility and comfort.

Given these benefits, it’s easy to see why window tinting is so popular. But with great tinting comes great responsibility—specifically, understanding the rules.

Understanding Tinting Terms: VLT & AS1

Before we look at each province’s laws, you should understand two important terms:

VLT (Visible Light Transmission):

This is the percentage of light that passes through your window and the tint. A lower VLT = darker tint.

AS1 Line:

This refers to a marking on your windshield, usually a few inches from the top, indicating the limit where tint can be applied.

Most provinces allow tinting on the rear and side windows, but they’re very strict about front side windows and windshields. Let’s break it down.

Canadian Car Window Tint Laws by Province (2025 Update)

Ontario

  • Front Windshield: Tint allowed only above the AS1 line or the top 3 inches.

  • Front Side Windows: Must allow 70% or more of light through.

  • Rear Side Windows & Rear Windshield: No restrictions.

Ontario is one of the more flexible provinces for rear windows, which is good news if you’re in areas like Mississauga or Brampton, where summer heat can get intense.

Quebec

  • Front Windshield: Tinting prohibited except for 15cm from the top.

  • Front Side Windows: Must allow at least 70% light.

  • Rear Windows: No restrictions.

Quebec’s laws are similar to Ontario’s and generally easy to follow for everyday drivers.

British Columbia (B.C.)

  • Front Windshield: No tint allowed.

  • Front Side Windows: No tint allowed.

  • Rear Side & Rear Windshield: Allowed.

This is one of the strictest provinces when it comes to front window tint. If you’re caught with tinted front side windows in B.C., you’ll be required to remove them immediately.

Alberta

  • Front Windshield: Tint not allowed.

  • Front Side Windows: Tint not allowed.

  • Rear Side & Rear Windshield: Allowed.

Similar to B.C., Alberta follows a no-tolerance policy for front tinting. Rear windows are fair game, though.

Manitoba

  • Front Windshield: No tint allowed.

  • Front Side Windows: Must let through at least 50% light.

  • Rear Side & Rear Windshield: Allowed.

Slightly more lenient than Alberta or B.C., Manitoba gives you a little room to work with on the front side windows.

Saskatchewan

  • Front Windshield: No tint.

  • Front Side Windows: No tint.

  • Rear Side & Rear Windshield: Allowed.

Another strict province for the front tint. Be cautious if you’re buying a used car with dark windows.

Nova Scotia

  • Front Windshield: Tint allowed only above AS1 line.

  • Front Side Windows: Must let at least 70% light through.

  • Rear Windows: No restrictions.

Good balance between visibility and rear privacy.

New Brunswick

  • Front Windshield: 75% VLT or greater.

  • Front Side Windows: Must be 70% VLT or higher.

  • Rear Windows: No specific VLT, but must not obstruct visibility.

This province focuses heavily on maintaining front visibility but allows flexibility in the back.

Prince Edward Island (PEI)

  • Front Windshield & Front Side Windows: Tint not allowed.

  • Rear Windows: Allowed.

Very strict upfront, but generous in the back.

Newfoundland and Labrador

  • Front Windshield: Tinting not allowed except for factory tint.

  • Front Side Windows: No tint allowed.

  • Rear Windows: Permitted.

Another example of a front-focused law. Rear tinting is fine, but keep it light up front.

Yukon, Northwest Territories, Nunavut

  • General Rule: No tint on front windshield or front side windows.

  • Rear Tinting: Usually permitted.

Since these areas experience long periods of darkness, visibility is a high priority.

Common Questions About Tinting Laws in Canada

What Happens If You Break Tint Laws?

You can be ticketed, ordered to remove the tint, or even fail a vehicle inspection. Penalties vary by province but can include fines ranging from $85 to over $150 per offense.

Can Factory Tinted Windows Be Made Darker?

Yes, but only on windows that are legally allowed to be tinted more. Front side windows can’t go below their minimum legal VLT.

How Is VLT Measured?

Law enforcement uses a VLT meter, which clamps onto your window and gives a digital readout. If you're unsure about your tint level, visit a car real expert or tinting shop for a quick check.

Expert Tips Before You Tint

Before heading to your local shop for car window tinting Brampton, keep these tips in mind:

1. Know Your Province’s Rules

Don’t just assume that what’s legal in one place is legal in another. Get your facts straight before investing in tinting.

2. Work with Certified Professionals

Reputable shops that specialize in car window tinting will know the laws and ensure your vehicle is compliant. Look for certified installers and ask about warranties.

3. Avoid DIY Tint Kits

Not only are these often poor quality, but you risk applying an illegal tint. Professionals will help you pick the right film and install it flawlessly.

4. Consider Ceramic Tint

If you want maximum UV protection without going too dark, ceramic films offer high performance with a lighter appearance.

5. Check for Insurance Implications

In rare cases, overly dark tints can affect your insurance coverage or claims, especially if the tint is deemed illegal.
