Existing Substances Evaluation

Welcome

The Existing Substances Branch represents the Department's expertise for ecological risk assessment of existing substances. Within Environment Canada, the Branch leads the Departmental program for assessing priority substances under the Canadian Environmental Protection Act, 1999 (CEPA 1999) as well as other initiatives under CEPA 1999. These include categorization and screening of the Domestic Substances List (DSL) as well as Section 75, which involves exchanging information and reviewing decisions from other jurisdictions on specifically prohibited or substantially restricted substances. The Branch is also involved in other federal, intergovernmental and international assessment initiatives including the Toxic Substances Management Policy (TSMP), and the chemicals program of the Organization for Economic Cooperation and Development (OECD).
