Canadian building code question

What are the building code requirements for accessible signage and wayfinding in Canada?

The NBC requires accessible signage provisions in barrier-free buildings, including tactile signage with raised characters and Braille at key locations, visual contrast requirements, and accessible wayfinding to exits, washrooms, and elevators.

Accessible signage ensures that all building occupants, including those with visual impairments, can navigate a building safely and independently. The National Building Code sets requirements for tactile signs, Braille, visual contrast, mounting height, and location as part of the broader barrier-free design provisions.

What to check first

  • Tactile signs with raised characters and Grade 2 Braille are required at key locations including washrooms, exits, and floor-level identification in stairwells.
  • Signs must provide visual contrast between characters and background, and between the sign and the mounting surface.
  • Mounting height and location requirements ensure signs are detectable and readable by people with varying abilities.

Jurisdiction notes

National baseline

NBC Part 3 Division B Subsection 3.8.3 covers barrier-free design requirements including signage provisions. CSA B651 is referenced for detailed accessibility standards.

Provincial variations

Provinces may adopt CSA B651 or provincial accessibility standards with additional signage requirements. Ontario's AODA and BC's accessibility legislation may add requirements beyond the building code.

Human rights compliance

Beyond building code minimums, human rights legislation and accessibility standards may require additional wayfinding features in public buildings.

Work through it in this order

  1. Identify all locations requiring accessible signage under the applicable building code and accessibility standards.
  2. Specify tactile sign requirements including raised character height, spacing, Braille grade, and mounting height.
  3. Verify visual contrast requirements between characters and background and between signs and mounting surfaces.
  4. Confirm wayfinding provisions for exits, washrooms, elevators, and floor-level identification.
  5. Check provincial accessibility legislation for requirements beyond the building code minimum.

Common questions

Where are tactile signs required in a building?

Tactile signs with raised characters and Braille are typically required at washroom entrances, exit doors, stairwell floor-level identification, and elevator call stations in barrier-free buildings.

What type of Braille is required on building signs?

Grade 2 (contracted) Braille is specified by the code and referenced accessibility standards for building signage in Canada.

Do all buildings need accessible signage?

Accessible signage requirements apply to buildings required to be barrier-free under the code. Most public, commercial, and multi-unit residential buildings must meet barrier-free design requirements.
