Domestic Substances List Amended — New Entries

Summary#

Order 2023-87-06-01 Amending the Domestic Substances List adds a set of chemicals and polymers to Canada’s main inventory of substances. The order was registered on May 11, 2023 and signed by Steven Guilbeault on May 9, 2023.

What it does#

• Adds 10 substance identifiers to Part 1 of the Domestic Substances List.
• Adds 6 named polymer entries to Part 3 of the Domestic Substances List.
• The changes were made under the Canadian Environmental Protection Act, 1999 and take effect on the day the order was registered (May 11, 2023).

(The order lists the new entries by identifier and by polymer name. The Gazette item that published the order shows the full list.)

Who's affected#

• Companies that make or import the specific substances or polymers named in the order.
• Businesses that use those chemicals in products or manufacturing processes.
• Regulators and anyone tracking which chemicals are considered "on the list" in Canada.

It is not clear from the order which branded products or industries will use these specific substances.

Why it matters#

• Being added to the Domestic Substances List generally means a chemical is recognized as already present in Canada. That can change whether a company must notify federal authorities before bringing the chemical into the country under the New Substances Notification Regulations (Chemicals and Polymers).
• For affected companies, this can reduce pre‑market paperwork for those specific entries. For the public, it updates which substances regulators consider existing in Canada and may affect future risk assessments or monitoring.
