Toxic air pollutants
Many pollutants that contribute, or may contribute, to air quality issues have been formally assessed and determined to be toxic under the Canadian Environmental Protection Act, 1999 (CEPA 1999) and are listed in Canadian Environmental Protection Act 1999 Schedule 1.
For more information about CEPA 1999, visit the Canadian Environmental Protection Act Registry, and for risk management information on some pollutants that contribute or may contribute to air quality issues visit the Management of Toxic Substances Website.
