Are Windshield Decals Legal in Canada?
Short answer: yes — clear vinyl and rear window decals are fully legal in Ontario. There is one restriction to know about opaque front windshield graphics.
Ontario's Highway Traffic Act sets a 70% visible light transmittance standard for front glass. Clear vinyl meets it. Opaque printed decals don't — but the rear window, doors, and every body panel are completely unrestricted. Plenty of legal surface area for your graphics.
What Ontario Law Actually Permits
Ontario Regulation 596 (Vehicle Equipment), Section 7, under the Highway Traffic Act sets a minimum visible light transmittance of 70% for the front windshield and all windows in the front seating compartment. This is the same standard applied to tinted windows.
Clear vinyl decals — where only the printed design is visible against a transparent film — have minimal impact on transmittance and are legal. The restriction is on opaque, solid-print decals that would block light across their full area. Required regulatory stickers (safety certificates, insurance evidence) are also explicitly permitted at designated windshield locations.
Outside the front windshield, Ontario law places no transmittance restrictions. The rear window, rear side windows, door panels, bumpers, hood, and all body surfaces are entirely unrestricted — making them the ideal surfaces for business branding, logo decals, and vehicle graphics.
Legal Vehicle Decal Surfaces in Ontario
Where you place your decal determines the rules. Here is the breakdown for each vehicle surface.
Clear Vinyl Window Sticker
Transparent-background vinyl lets your design show without blocking light transmittance. Legal on front side windows and rear glass. Most popular choice for business logos and QR codes on vehicle glass in Ontario.
Shop window stickers →Rear Window Decal
Decals on rear glass are not subject to the 70% transmittance rule. Perforated vinyl gives full-coverage graphics while maintaining the driver's rearview through the perforations. A solid corner sticker is also legal here.
Shop rear window decals →Door, Hood & Body Panel Decals
Any surface that is not glass is completely unrestricted. Door panels, hood, trunk lid, bumpers, and roof are the best advertising real estate on your vehicle — no transmittance rules apply.
Shop car decals →Opaque Front Windshield Decal
Solid, opaque decals on the front windshield are restricted under Ontario HTA O. Reg. 596, s.7 — front glass must maintain 70% visible light transmittance. Use clear vinyl instead, or place graphics on legal surfaces.

Frequently Asked Questions
Frequently asked questions
Are windshield decals legal in Ontario?‹
Clear vinyl decals are legal on Ontario vehicle windows. Ontario Regulation 596 under the Highway Traffic Act requires front glass to maintain at least 70% visible light transmittance — clear vinyl meets this because only the printed design occupies space, not a solid opaque film. Opaque printed decals on the front windshield do not meet the transmittance standard and can result in a defect notice.
What types of windshield decals are legal in Canada?‹
Clear vinyl stickers (transparent background) are the legal option for front glass. Legally required stickers such as provincial safety certificates, Drive Clean stickers, and insurance evidence markers are also permitted at their designated windshield locations. For maximum surface area, rear window and side-window decals face fewer restrictions and are popular for vehicle advertising.
Can I put decals on my rear window in Ontario?‹
Yes. Rear window decals are fully legal in Ontario. The 70% transmittance rule applies only to the front windshield and front seating-area side windows. Rear glass is unrestricted — full-coverage perforated vinyl, solid corner stickers, and partial decals are all permitted provided the driver still has adequate rearview through mirrors.
Are business logo decals on vehicles legal in Ontario?‹
Yes. Business logo and advertising decals are legal on vehicle doors, rear windows, bumpers, and other body panels. Clear vinyl logos are also legal on front side windows. The only restricted surface for opaque printed material is the front windshield. Fleet graphics and commercial vehicle decals are a standard marketing practice in Ontario.
Do I need a permit for vehicle decals in Ontario?‹
No permit is required for decorative or business advertising decals in Ontario. Commercial vehicles over a certain GVW are required by law to display CVOR numbers and company information on their doors — that is a separate compliance requirement handled by our regulated-markings specialist. For personal or small-business vehicle graphics, no permit is needed; compliance is about placement (avoiding restricted windshield surfaces), not permission.
