The Status of Prioritized Substances List reflects any changes in prioritization that have occurred since Categorization based on new information received as part of the first phase of the Chemicals Management Plan.

The New Substances Program's Search Engine for Chemicals, biochemicals, polymers and biopolymers published in the Canada Gazette and List of Organisms on the Domestic Substances List can be used to search for substances on the DSL.  With few exemptions, all substances not on this list are considered new and must be reported prior to importation or manufacture in order that they can be assessed to determine if they are toxic or could become toxic to the environment or human health.
