11 Substances Added to Domestic List

Summary#

Order 2022-87-08-01 Amending the Domestic Substances List adds 11 substances to the Domestic Substances List under the Canadian Environmental Protection Act, 1999. The Order was registered on August 16, 2022 and published in the Canada Gazette on August 31, 2022, and it came into force on registration.

What it does#

• Adds 11 substances to the Domestic Substances List so they are no longer treated as “new” in Canada.
• Specifically:
  • 6 substances (listed by CAS Registry Number) were added to Part 1:
    • 83653-00-3
    • 120313-48-6
    • 174254-17-2
    • 174254-24-1
    • 1650591-28-8
    • 1883583-80-9
  • 5 substances (listed by masked names and confidential accession numbers) were added to Part 3:
    • 19605-3 N — Benzenedicarboxylic acid, polymer with α‑hydro‑ω‑hydroxypoly(oxyalkanediyl) and oxybis[ethanol]
    • 19606-4 N‑P — Fatty acids, C18‑unsatd., dimers, hydrogenated, polymers with … (masked name)
    • 19607-5 N‑P — 2‑Propenoic acid, 2‑methyl‑, substituted‑alkyl ester, polymer with … (masked name)
    • 19608-6 N‑P — Amines, tallow alkyl ethoxylated, compds. with oxidized polyalkylene
    • 19609-7 N — Alkenoic acid, compd. with polyalkylamino(ethanol)
• As a result, these substances are no longer subject to the notification requirements of the New Substances Notification Regulations (Chemicals and Polymers).
• The Order is administrative: it does not add new rules or restrictions on how the substances may be used.

Who's affected#

• Companies that manufacture, import or sell the listed chemicals or polymers in Canada.
• Chemical suppliers and downstream product manufacturers who may use these substances in formulations or industrial processes.
• Regulators and people tracking chemical inventories.
• The general public is unlikely to notice a direct change; the Order mainly affects business regulatory steps.

Why it matters#

• For businesses: removing these substances from the “new” category makes it easier to bring them into the Canadian market because the specific pre-market notification step is no longer required.
• For consumers and communities: the Order does not mean the government has declared the substances safe; other laws and assessments still apply.
• For transparency: five of the substances are listed under masked names to protect confidential business information, so their full identities are not publicly disclosed in the listing.
• The Order is procedural — it completes a legal step after the government’s assessment and does not itself impose new limits or controls.
