DSL Amendments: 21 Additions and Removals

Summary#

Order 2024-66-08-01 Amending the Domestic Substances List: SOR/2024-205 updates Canada’s list of chemical substances. It adds 21 substance entries to Part 1 of the Domestic Substances List and removes 21 entries from Part 3. The order was registered on October 15, 2024 and published in the Canada Gazette on November 6, 2024; it was signed by Steven Guilbeault, the Minister of the Environment.

What it does#

• Adds 21 specific substance entries (listed by CAS registry number) to Part 1 of the Domestic Substances List. The CAS numbers added include, for example, 37208-94-9, 114615-89-3, 121758-82-5, and others (full list in the Canada Gazette item).
• Deletes 21 named substance entries from Part 3 of the Domestic Substances List. The deletions include entries listed by CAS number and chemical name (for example, 11015-8 2,5‑Pyrolidinedione, isoalkenyl derivatives; 13294-1 2‑Propenoic acid, 2‑methyl‑…; and others).
• The order “comes into force on the day on which it is registered” — that is, October 15, 2024.
• The Canada Gazette entry notes that the Regulatory Impact Analysis Statement for this change appears following SOR/2024-206.

Who's affected#

• Companies that make, import, sell, or use the specific chemicals named on the list.
• Chemical distributors and downstream product manufacturers who handle these substances.
• Regulators and others who track or manage chemical inventories and assessments in Canada.
• The general public might be indirectly affected if these substances are used in consumer products, but the Gazette item does not explain specific product links.

If it’s unclear whether a particular business or product is affected, the Canada Gazette item lists the exact CAS numbers and chemical names to check against your inventory.

Why it matters#

• Being on or removed from the Domestic Substances List can change how a substance is tracked and reviewed by federal regulators. Businesses often need to check the DSL to know whether they have reporting, testing, or other obligations under Canadian chemical laws.
• The change could affect supply chains and compliance steps for companies that handle the listed substances.
• The Gazette entry itself does not spell out detailed consequences for each substance; for more explanation of impacts, see the Regulatory Impact Analysis Statement referenced with SOR/2024-206 or consult the full Canada Gazette item.
