The purpose of CAN-ASC-2.2 is to ensure the technical requirements for emergency egress are equity-based. This requires going beyond minimum technical specifications. 
There are common areas where persons with disabilities may face barriers related to emergency egress (exiting a space). For example:

  • Information and awareness. This includes knowledge of available accommodations in the event of an emergency.
  • Lack of clear emergency egress solutions. These include visual fire alarms, proper signage, and areas of refuge. Other solutions include accessible egress routes, evacuation plans, and other areas.

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 Canadians with disabilities. This includes the members of its 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.
