11 Substances Added to Domestic List

Summary#

Order 2021-87-17-01 Amending the Domestic Substances List adds 11 substances (chemicals and polymers) to Canada’s inventory of in‑commerce substances. The change took effect on December 21, 2021, and means these substances are no longer treated as “new” under federal new‑substance rules.

What it does#

• Adds 11 substances to the Domestic Substances List:
  • 3 substances (identified by CAS numbers) were added to Part 1.
  • 8 substances (listed by masked names and Confidential Accession Numbers) were added to Part 3.
• Removes those substances from the need to notify under the New Substances Notification Regulations (Chemicals and Polymers) — businesses that supplied or imported them no longer have to follow those specific new‑substance notification steps for these items.
• The order came into force on December 21, 2021.
• The government says this is an administrative action and does not create new regulatory requirements or costs.

Who's affected#

• Manufacturers and importers of the listed substances in Canada.
• Chemical suppliers and companies that use these specific chemicals or polymers in products or manufacturing.
• The general public and most other businesses are unlikely to notice any immediate change.
• It is not clear from the order whether any specific consumer products or industries will see direct effects; the listing itself does not say how widely each substance is used.

Why it matters#

• For businesses: adding a substance to the Domestic Substances List usually makes it easier to bring the substance into the Canadian market because the extra notification steps for “new” substances no longer apply.
• For the public: the addition is administrative and does not mean the government endorses the safety of these substances. They remain subject to other laws and could still be assessed or regulated separately under the Canadian Environmental Protection Act, 1999 if risks arise.
• For transparency: eight substances were added under masked names to protect confidential business information, so public detail about those substances is limited in the order.
