The purpose of standard CAN-ASC-2.4 is to ensure the technical requirements for wayfinding and signage are equity-based. This requires going beyond minimum technical specifications.
There are common areas where persons with disabilities may face barriers related to wayfinding and signage. For example, it is important that the following support accessibility:

  • Tactile walking surface indicators. These are indicators that can be used to get attention. They can also provide guidance or direction.
  • Signage (indoor and outdoor) that uses:
    • tactile lettering
    • Braille
    • graphical symbols
    • other means to convey information, such as maps, diagrams, and directional content
  • Lighting
  • Audible beacons
  • Public announcements 
  • Acoustics 
  • Hearing loops and assistive listening systems  
  • Emerging technologies
  • Wayfinding and signage for: 
    • transportation
    • emergencies (see the Emergency Egress and Emergency Measures standard currently being developed by Accessibility Standards Canada)
  • Signage for indoor and outdoor paths of travel (see also the Outdoor Spaces standard currently being developed by Accessibility Standards Canada)
  • Wayfinding cues, such as colour and texture contrast. 

Project need

Accessibility Standards Canada was created under the Accessible Canada Act. Its mandate is to prevent, identify, and remove barriers to accessibility in Canada for people with disabilities. To do this, it develops standards. These are based on the needs of people with disabilities. These needs are identified by consulting with Canadians with disabilities. This includes the members of the Accessibility Standards Canada Board of Directors. Most Board members are people with disabilities. The Board has approved the development of this standard. 
Accessibility Standards Canada standards are developed following the principle of “nothing without us.” This means that people with disabilities are involved in the development process:

  • Its standards are developed using research that is led by people with disabilities or with lived experience.
  • People with disabilities are members of the organization’s technical committees. These committees produce equity-based requirements for standards. These take into account the needs and perspectives of people with disabilities. 
  • The public review process for this standard will be accessible. This will allow even more people with disabilities to be part of the development process.
