There are only a few references which specifically mention "indoor air quality" in Canadian legislation. This list is of what is available on the CCOHS Canadian EnviroOSH Legislation plus Standards service. Where legislation does not exist, the jurisdictions should be contacted for the most current information. Check the Canadian Governmental Occupational Health & Safety Departments (http://www.ccohs.ca/oshanswers/information/govt.html) list for contact information.

The ASHRAE Standard 62-2004 "Ventilation for Acceptable Indoor Air Quality" is widely used as a guide. It is available from the American Society of Heating, Refrigerating and Air-Conditioning Engineers. ASHRAE can be contacted at: https://www.ashrae.org

In some cases, the Building Code for your area may apply.

Additional information is available from other sources such as:

Treasury Board Directive "Occupational Health and Safety Directive"

Some of the references regarding Environmental Tobacco Smoke in workplaces may also apply.
