New Substances Added to Domestic List

Summary#

This is Order 2024-87-04-01 Amending the Domestic Substances List (registered as SOR/2024-82). It adds several chemical identifiers and substance entries to the federal Domestic Substances List. The order was registered on May 9, 2024 and published in the Canada Gazette on May 22, 2024.

What it does#

• Adds these CAS numbers to Part 1 of the Domestic Substances List:

  • 67762-83-8 (N-P)
  • 78213-16-8 (N)
  • 167208-61-9 (N-P)
  • 308336-53-0 (N)
  • 905952-76-3 (N-P)
  • 1417986-34-5 (N-P)

• Adds these entries to Part 3 of the Domestic Substances List (with CAS numbers and the names as shown in the order):

  • 19707-5 (N-P) — Alkanepolyamine, polymer with polyisocyanato-1-methylbenzene, polyalkylene-polypropylene glycolmono-Bu ether-blocked
  • 19708-6 (N-P) — Waste plastics, poly(ethylene terephthalate), polymers with diethylene glycol, polysubstitued alkane and phthalic anhydride
  • 19709-7 (N-P) — Castor oil, dehydrated, polymer with ethylenediamine, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid, 5-substituted-1-(substitutedmethyl)-1,3,3-trialkylcarbomonocycle and polyethylene glycol 2,2-bis(hydroxymethyl)butyl Me ether
  • 19710-8 (N) — 1,4-Benzenedicarboxylic acid, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol, alkanedioic acid, α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), 1,3-isobenzofurandione, 4-methyl-1,3-dioxolan-2-one, 2,2’-oxybis[ethanol] and 1,2,3-propanetriol

• The order took effect on the day it was registered (May 9, 2024).

• The order notes that the Minister of the Environment and the Minister of Health were satisfied that the person who provided information had manufactured or imported the listed substances in Canada above the threshold set by the New Substances Notification Regulations (Chemicals and Polymers), and that the period for assessing that information had expired.

Who's affected#

• Companies or people who manufacture, import, or supply the specific listed substances in Canada.
• Downstream users who handle products or mixtures that contain these listed substances.
• Environmental and public-health officials and groups who track which chemicals are present in Canadian commerce.
• The order itself names the federal ministers involved; it does not list specific companies. It is therefore not clear from the order which specific businesses or products are involved.

Why it matters#

• Being added to the Domestic Substances List officially records these chemicals as present in Canadian commerce.
• That status can affect how the government tracks, assesses and manages risks for these chemicals in the future.
• For businesses, the listing documents that these substances were manufactured or imported above notification thresholds — information that can influence regulatory steps, monitoring, or future reporting requirements.
• The order is part of routine chemical management under the Canadian Environmental Protection Act, 1999; the Regulatory Impact Analysis Statement related to these changes appears alongside related orders (see SOR/2024-83).
