Which Signs Need to Be Accessible?
Under the AODA's Design of Public Spaces Standards (O.Reg 413/12, Part IV.1, Section 80.40), the following signs in publicly accessible buildings must include both Braille and tactile characters:
🚻 Washroom Signs
Men's, Women's, Universal, Family, and Gender-Neutral washrooms. This is the #1 inspection trigger.
🚪 Entrance Signs
Accessible entrances, main entrances, and side entrances used by the public.
🚨 Exit Signs
Emergency exits, accessible exit routes, and evacuation route maps. Tactile exit signs complement illuminated signs.
🔢 Stairwell Signs
Floor identification at each stairwell landing. Must show floor number in raised tactile characters with Braille.
🏢 Room Identification Signs
Meeting rooms, offices, service counters, and any room the public accesses.
🛗 Elevator Signs
Floor numbers, direction indicators, and elevator call buttons require tactile and Braille markings.
♿ Parking Signs
Accessible parking spaces must be identified with the International Symbol of Accessibility and proper ground markings.
🧭 Wayfinding Signs
Directional signs guiding people through buildings — especially at decision points like corridors and lobbies.

Braille Specifications (O.Reg 413/12)
Ontario's AODA regulations specify Grade 2 (contracted) Braille — not Grade 1. This is a critical distinction. Many sign vendors supply Grade 1 Braille, which does not meet Ontario requirements. Every specification must be met for the sign to pass inspection:
⚠️ Common Vendor Mistake
Many sign companies use computer-generated Braille that produces flat-topped dots. AODA requires dome-shaped dots. If your current signs have flat Braille dots, they will fail inspection. We produce signs with thermoformed dome-shaped Braille beads that meet the full specification.
Tactile Character Requirements
Tactile characters are the raised text on AODA signs — these are what a person with low vision reads by touch. The specifications are precise:
Mounting Height & Placement
Where you mount the sign is just as important as the sign itself. Incorrect placement is the second most common AODA violation after missing signs entirely:
- ✓Height: Centre of sign between 1,200 mm and 1,500 mm from the finished floor level
- ✓Position: Adjacent to the latch side of the door (the side you push or pull — NOT the hinge side)
- ✓NOT on the door: Signs must be mounted on the wall beside the door, NOT on the door itself (doors move and signs become unreachable)
- ✓Distance from frame: Within 150 mm of the door frame edge
- ✓No wall space: If no wall is available beside the door, mount on the nearest wall perpendicular to the door approach
- ✓Double doors: Mount on the wall to the right of the right-hand door (assuming standard approach)
Colour Contrast Requirements
AODA requires a minimum 70% colour contrast ratio between the text/pictogram and the sign background. This applies to both the visual appearance and the tactile elements. Common compliant combinations:
Sample Text
White on Dark Navy — 95%+ contrast
Sample Text
Dark Navy on White — 95%+ contrast
Sample Text
Yellow on Dark Blue — 85%+ contrast
Sample Text
Dark Blue on White — 90%+ contrast
Avoid these combinations — they typically fail the 70% minimum:
- ✕ Light grey on white
- ✕ Medium blue on dark blue
- ✕ Red on green (also problematic for colour blindness)
- ✕ Yellow on white
- ✕ Any combination with glossy finish (glare reduces effective contrast)

Wayfinding & Directional Signs
Wayfinding signs guide people through a building to their destination. Under AODA, wayfinding systems in public buildings must be accessible to people with visual, cognitive, and mobility disabilities. Requirements include:
- Consistent placement: Wayfinding signs at every decision point (corridor intersections, elevator lobbies, stairwell exits)
- High contrast: Minimum 70% contrast between text/arrows and background
- Large text: Directional text readable from a distance — minimum 25 mm for corridor signs
- Pictograms with text: Universal symbols must be accompanied by text — symbols alone are not sufficient
- Tactile maps: For large facilities, tactile maps at main entrances showing building layout, exits, elevators, and washrooms
- Consistent style: All wayfinding signs within a building must use the same font, colour scheme, and layout
For Toronto businesses, the Toronto Accessibility Design Guidelines add additional wayfinding requirements beyond the provincial AODA standards, including specific sign sizes for different building types.
Directional Ground Surface Indicators
AODA requires Attention Indicators and Directional Indicators (also called tactile walking surface indicators or tactile plates) at specific locations. These are the textured ground surfaces that people with visual disabilities detect with a cane or underfoot:
Truncated Domes (Attention Indicators)
Required at the top and bottom of stairs, at transit platforms, and at pedestrian crossings. The dome pattern warns of a hazard ahead. Dot diameter: 12 mm, height: 5 mm, centre-to-centre: 50-60 mm.
Elongated Bars (Directional Indicators)
Used to guide pedestrians along a specific path. Common in transit stations, hospital corridors, and large public buildings. Bar width: 17-30 mm, gap between bars: 17-30 mm, aligned in direction of travel.
Colour Contrast
Ground surface indicators must contrast with the surrounding floor by at least 70%. Yellow on grey concrete is the most common compliant combination.
Material
Must be slip-resistant, durable, and detectable by a white cane. Stainless steel, porcelain, and composite polymer are common materials.
Who Needs AODA Signs?
If your business has a physical location that the public enters, you need AODA-compliant signage. This includes:
The only exemptions are private residences (not home-based businesses open to the public) and buildings under construction that are not yet occupied.
Penalties for Non-Compliance
AODA penalties are among the steepest in Ontario regulation. The Accessibility Directorate can issue compliance orders, and refusal to comply triggers daily fines:
Beyond fines, businesses that fail AODA audits face:
- ✕ Public disclosure of non-compliance on the Ontario government website
- ✕ Loss of government contracts and procurement eligibility
- ✕ Human Rights Tribunal complaints from individuals denied access
- ✕ Insurance liability exposure if someone is injured due to inaccessible signage
- ✕ Forced remediation at inflated rush-order costs
Common AODA Signage Mistakes
These are the violations we see most frequently when auditing Ontario businesses:
AODA Signage Compliance Checklist
Walk your building with this checklist. Every item must pass for full AODA compliance:
Washrooms
- All washrooms have tactile + Braille signs
- Signs mounted on wall, latch side of door

- Grade 2 contracted Braille with dome-shaped dots
- Matte finish, sans-serif font, 70%+ contrast
Stairwells
- Tactile floor number at every landing
- Braille below floor number
- Attention indicators (truncated domes) at top of stairs
Entrances & Exits
- Accessible entrance identified with ISA symbol + tactile
- Exit signs include tactile route information
- Power door buttons at accessible entrances
Wayfinding & General
- Directional signs at every decision point
- Consistent sign design throughout building
- All signs within 150 mm of door frame
- No signs mounted on doors (wall only)
Toronto-Specific AODA Requirements
The City of Toronto Accessibility Design Guidelines go beyond the provincial AODA standards in several areas:
- Multi-storey buildings: Tactile floor plans at main entrances showing exits, elevators, washrooms, and stairs
- Colour coding: Consistent floor-by-floor colour coding system in addition to tactile signage
- Font size: Minimum 25 mm for room identification signs in Toronto city-owned buildings
- Bilingual signs: In some Toronto facilities, signs must include both English and French with tactile and Braille
- Retrofitting deadlines: Toronto Building Code enforcement may require signage upgrades during renovation permits
For businesses outside Toronto, your municipality may have additional requirements beyond the provincial AODA standards. Contact your local building department or accessibility advisory committee.
