CSA/ASC B651 Accessible Design for the Built Environment

This standard contains requirements for making buildings and other facilities accessible to individuals with a range of physical, sensory, and cognitive disabilities. It is a new edition of a previous standard. It addresses the design aspects of physical spaces and the elements within them to remove barriers to access, including:

• updated dimensions for platforms, tactile direction indicator positioning, and more, based on current data from anthropometric research;
• a detailed explanation of luminance (colour) contrast and its application;
• updated guidance on addressing functional and cognitive barriers;
• revised guidance for the controls and sizes of power-assisted doors; and,
• updated recommendations for water bottle filling stations and controls.

This standard is referenced in the National Building Code and other legislation across Canada.
