Lists of substances: Canadian Environmental Protection Act, 1999
Parts 5 and 6 of the Canadian Environmental Protection Act, 1999 (CEPA) focus on understanding and reducing the risks posed by new and existing substances. It provides for the assessment of these substances, which should be evaluated to determine whether they meet any of the criteria set out in section 64 of the Act. Parts 5 and 6 also confer the authority to implement, when appropriate, preventive or control measures in regard to the relevant aspects of the substance life cycle. Environment and Climate Change Canada shares with Health Canada the task of conducting risk assessments as well as the management associated with toxic substances.
In order to distinguish new substances from existing ones and to prescribe reporting requirements for new substances, as well as to determine which are or may be subject to risk management provisions, the Act has established or provided for the establishment of substance inventories or lists.
Domestic Substances List
The Domestic Substances List (DSL) is a list of substances manufactured in or imported into Canada on a commercial scale.

The DSL is amended, on average, 12 times per year to add, update or delete substances and now contains more than 28 000 entries. The DSL can be accessed through Substances Search.
