By: Ontario Window Tint Laws Help You Avoid Fines on the Road
Ontario window tinting remains popular for its privacy, UV protection, and comfort. Yet, strict regulations govern how dark your tint can be—especially in Ajax and Oshawa, which follow provincial standards. This 2025 guide breaks down legal tint levels, fines, and local nuances for clarity and compliance.
1. Understanding Ontario’s Tint Laws
Under the Highway Traffic Act and updated 2025 Ministry of Transportation guidelines:
Front Windshield
No aftermarket tint is allowed; only a shaded sun-visor strip up to 75 mm (3 in) at the top is legal.
Front Driver & Passenger Windows
Must allow at least 70% visible light transmission (VLT)—meaning no more than 30% tint, which ensures visibility for both drivers and police.
Rear Side Windows & Back Windshield
No legal VLT limit applies. However, you must have dual external side mirrors if these windows are tinted.
Prohibited Materials
Reflective or mirror-style tint is strictly banned.
2. Why These Rules Matter
Safety & Visibility: Dark tints on front windows can obscure driver visibility, make it hard for law enforcement to see inside, and hinder making eye contact with pedestrians and cyclists.
- Compliance during Inspections: Vehicles with improper tint may fail safety inspections, especially during resale or when obtaining a Safety Standards Certificate.

3. Fines & Penalties for Non-Compliance
Breaking Ontario tint laws can result in:
- Fines between CAD 85 and 500, depending on the violation’s severity.
- A “remove tint” notice, requiring tint removal to pass inspections.
- Failed vehicle inspection, which may delay registration or resale.
- Insurance complications, particularly if accidents occur in jurisdictions with different tint laws.
4. Ajax & Oshawa: What Local Drivers Should Know
Ajax and Oshawa follow the same provincial rules:
- Front windshield: Only the top 75 mm strip is allowed.
- Front windows: Maximum 30% tint (70% VLT).
- Rear windows: Dark tint is okay, but ensure dual side mirrors.
While local enforcement may vary, it’s best to comply to avoid legal hassles and ensure safety.
