Are Stickers Allowed on Cars?
Short answer: yes. Stickers are legal on cars in Canada. The law restricts obstructed driver vision — not stickers.
Ontario's Highway Traffic Act (s.73) targets objects that block the driver's view. Bumper stickers, body decals, and most window graphics are completely unrestricted. Here's exactly where each placement stands legally.
What Ontario Law Actually Says
Ontario's Highway Traffic Act, s.73(1) prohibits driving with any object or material that obstructs the driver's view to the front or sides. A parallel provision covers the requirement for an adequate rear view through mirrors or the rear window.
The Act says nothing about stickers as a category. It is silent on bumper stickers, door graphics, hood decals, or rear window designs. The only question the law asks is: does this object impair what the driver can see?
For the vast majority of sticker placements — bumper, body panels, rear passenger glass, and properly placed window decals — the answer is clearly no. Those placements are legal, full stop.
Sticker Placement — Legal Status by Location
Every common placement on a car, rated against Ontario's Highway Traffic Act.
Bumper
Front and rear bumper stickers have zero visibility impact on the driver. No provincial or federal law restricts stickers here. The most popular placement in Canada.
Shop bumper stickers →Body Panels (Doors, Hood, Quarters)
Decals on the painted body of the vehicle are unrestricted. Lettering, logos, graphics, and full-colour wraps are all permitted — no vision obstruction, no legal issue.
Shop car decals →Rear Window
Stickers are permitted on the rear glass provided driver rearview is not materially obstructed. Perforated vinyl, corner decals, and partial graphics are uniformly accepted. Full-coverage solid stickers carry some risk under HTA s.73.
See rear window rules →Side Windows (Rear Passenger)
Stickers on rear passenger side glass are generally permitted. The driver's direct sightlines — left side mirror view, rearward visibility — must remain clear. Small graphics or partial decals are uncontroversial.
Shop car decals →Front Side Windows (Driver + Passenger)
Ontario's HTA s.73 requires the driver's left and right field of vision to remain clear. Small stickers in the lower corners of front side windows are generally tolerated; larger graphics that block mirror sightlines may be cited.
Windshield (Driver's Direct View)
Stickers that obstruct the driver's forward view through the windshield are prohibited under HTA s.73. Exemptions exist for GPS mounts, toll transponders, and parking permits in designated spots — not decorative stickers.

Frequently Asked Questions
Frequently asked questions
Are stickers legal on cars in Canada?‹
Yes. There is no federal or provincial law in Canada that bans stickers on vehicles. Ontario's Highway Traffic Act (s.73) prohibits obstructing the driver's view — which is a different thing entirely. Bumper stickers, body decals, and properly placed window stickers are all legal.
Can police give you a ticket for having stickers on your car?‹
Only if a sticker obstructs the driver's vision under HTA s.73. A bumper sticker, hood graphic, or corner window decal cannot legally be the basis for a ticket. A solid sticker covering your entire front windshield — blocking your forward view — is a different matter.
Are bumper stickers legal in Ontario?‹
Completely legal. Bumper stickers are mounted on the rear bumper, well outside any driver sightline. No Ontario or Canadian regulation restricts them by content, size, or quantity — provided the licence plate remains visible and unobscured.
Can I put stickers on my car doors or hood?‹
Yes. Body-panel decals and graphics on doors, hood, quarter panels, and roof are unrestricted. Vehicle wraps — which are essentially large stickers — are a standard commercial and personal customisation with no legal constraint beyond what's covered by basic traffic visibility rules.
Do car stickers affect vehicle safety inspections in Ontario?‹
Safety inspections under Ontario Regulation 611 check for materially impaired driver visibility. Bumper stickers, body decals, and window graphics that leave the driver's forward and rearward sightlines clear will not cause an inspection failure.
Can I put a sticker on my car windows?‹
Yes, with placement in mind. Rear window: legal with the right sticker type (perforated vinyl or partial decals). Rear passenger side glass: generally legal for smaller graphics. Front side windows: keep large graphics away from the driver's direct mirror sightlines. Windshield: no stickers in the driver's direct forward-view zone.
