Summary

Summary#

This is Order 2025-87-10-01 Amending the Domestic Substances List (SOR/2025-216). It adds several chemical entries to Canada’s Domestic Substances List and came into force on the day it was registered (October 28, 2025). The order was signed by Julie Dabrusin, Minister of the Environment.

What it does#

  • Adds the following entries to Part 1 of the Domestic Substances List:
    • 1514-82-5 N
    • 321657-09-4 N
    • 2896195-16-5 N-P
  • Adds the following entries to Part 3 of the Domestic Substances List:
    • 19792-0 N — Fatty acids, alkane, triesters with polyalkylene glycol ether with glycerol (3:1)
    • 19793-1 N-P — Diheteromonocycle, polymer with alkenyl carbomonocyclic, ester with 2-methyloxirane polymer with oxirane (2-propylheptyl) ether, compd with nitrilopoly[alkanol]
    • 19794-2 N-P — Alkene polymers with alkyl acrylate
    • 19797-5 N-P — Alkanal, polymers with 4-alkylphenol, p-alkylphenol and alkylene oxide
  • States that the Order comes into force on the day it was registered (October 28, 2025).
  • Notes that the Regulatory Impact Analysis Statement for this Order appears with SOR/2025-217 (mentioned in the Gazette entry).

(The source shows short codes like “N” and “N‑P” after entries; the item does not explain those codes.)

Who's affected#

  • Companies that manufacture, import, sell or use the specific substances listed above in Canada.
  • Laboratories, distributors, and downstream users who handle these substances.
  • Government regulators and analysts who track and assess chemicals under the Canadian Environmental Protection Act, 1999.

If you handle or trade chemicals, this is the group most likely to notice the change. The Gazette notice itself does not list specific industries or companies.

Why it matters#

  • The Domestic Substances List is Canada’s official inventory of chemicals that are noted for tracking and assessment. Adding these entries updates that inventory.
  • For businesses, an entry can change how a substance is tracked, reported, or considered in future assessments or regulatory actions — though this particular notice does not spell out any new rules or immediate obligations.
  • For the public and regulators, the change helps clarify which substances are on Canada’s chemical list and points to where more information (the Regulatory Impact Analysis Statement) can be found.
