Priority Substances List
The Canadian Environmental Protection Act, 1999 (CEPA 1999, section 76) requires the Ministers of the Environment and of Health to establish a Priority Substances List (PSL) that identifies substances to be assessed on a priority basis to determine whether they are toxic (as defined under Section 64 of the Act) and pose a risk to the health of Canadians or to the environment. Assessments of substances placed on the PSL are the shared responsibility of Environment Canada and Health Canada. A Priority Substance may be a chemical, a group or class of chemicals, effluents or wastes.
Assessments of the first 44 substances placed on the list (PSL1) were completed by February 1994. Following the recommendations of a multi-stakeholder Expert Advisory Panel, 25 substances were added to the list (PSL2).
