Introduction to Domestic Substances List (DSL)

The Domestic Substances List (DSL) is an inventory of substances manufactured in, or imported into Canada on a commercial scale. Substances on the DSL are grouped into 8 parts and may have one or more of the 5 available flags. For example, the S flag indicates that the substance is subject to Significant New Activity (SNAc*) requirements and is applied when the substance was subject to SNAc requirements prior to its addition to the DSL.

• Part 1: Chemicals and polymers that are identified by their CAS numbers, or their Substance Identity Number assigned by the Department of the Environment and the name of the substance;
• Part 2: Chemicals and polymers subject to SNAc requirements that are identified by their CAS numbers.

An introduction to other parts of the DSL can be found here.

*The SNAc provisions trigger an obligation for a person to submit a significant new activity notification (SNAN) to the government when proposing to use, import or manufacture the substance for a significant new activity. The government will then assess the substance for potential risks to human health and the environment. If risks are identified, the government may impose management measures.
