Twelve Substances Added to Domestic Substances List

Summary#

The Order 2021-87-09-01 Amending the Domestic Substances List adds a set of chemical substances to Canada’s inventory of known substances. The order was registered on July 28, 2021 and published in the Canada Gazette on August 18, 2021.

What it does#

• Adds 6 entries to Part 1 of the Domestic Substances List and 6 entries to Part 3 — 12 substances in total.
• The substances added are identified by chemical names and CAS numbers in the order.
• The order states that the relevant ministers had information showing these substances were already being manufactured in or imported into Canada in amounts above the reporting threshold, and that the formal assessment period had ended.
• The order came into force on the day it was registered: July 28, 2021.

Who's affected#

• Chemical manufacturers and importers who deal with the specific substances named in the order.
• Companies that use those chemicals as raw materials, intermediates, or in formulation may notice the change.
• Regulators and anyone tracking the presence of specific chemicals in Canadian commerce.
• It is not clear from the order which consumer products (if any) contain these particular substances.

Why it matters#

• Being on the Domestic Substances List means a substance is recognized as existing in Canadian commerce. That can change what regulatory steps a company must take when bringing a substance into Canada in the future.
• For businesses, it may reduce the need to submit "new substance" notifications for these chemicals, because they are no longer treated as new.
• For the public and regulators, the listing improves transparency about which chemicals are present in Canada and helps prioritize monitoring and risk management.
