Substances Added to Domestic Substances List

Summary#

Order 2026-87-05-01 Amending the Domestic Substances List (registered as SOR/2026-84) adds several chemical substances to Canada’s Domestic Substances List. The Order was registered on May 13, 2026 and published in the Canada Gazette, Part II on June 3, 2026. It comes into force on the day it was registered.

What it does#

• Adds the following CAS numbers to Part 1 of the Domestic Substances List:
  • 9011-12-5 N-P
  • 65870-97-5 N
  • 68525-95-1 N-P
• Adds the following entries to Part 3 of the Domestic Substances List (CAS number followed by chemical name when given):
  • 19818-6 N-P — 1,3‑Benzenedicarboxylic acid, polymer with 1,4‑benzenedicarboxylic acid, 2,2‑bis(hydroxymethyl)-alkanediol and 2,2‑dimethyl-alkanediol
  • 19819-7 N — Fatty acids, plant-based oil, polymers with bisphenol A, diethanolamine, N1,N1-dimethyl-1,3-propanediamine, epichlorohydrin, soybean oil and triethylenetetramine, (S)-lactates (salts)
  • 19820-8 N-P — 1,4‑Benzenedicarboxylic acid, polymer with 1,3‑dihydro-1,3-dioxo-5‑isobenzofurancarboxylic acid, dimethyl-alkanediol, 1,2‑ethanediol, hexanedioic acid and 2,2′-oxybis[ethanol]
• The Order notes that the Minister of the Environment and the Minister of Health were satisfied the required information had been provided and that the statutory assessment period had expired before the additions were made.

Who's affected#

• Companies that manufacture or import the listed chemicals into Canada.
• Chemical suppliers, formulators, and possibly downstream businesses that use these substances in products.
• Regulators and public health or environment officials who track which chemicals are present in Canadian commerce.

If it is unclear whether a specific business or product is affected, those parties would need to check whether they handle any of the listed CAS numbers or chemical names.

Why it matters#

• Being added to the Domestic Substances List means the federal government now recognizes these specific chemicals as existing in Canadian commerce.
• That recognition can change how the substances are tracked, reviewed or managed under the Canadian Environmental Protection Act, 1999.
• Businesses who make or import these substances will want to confirm how the listing affects their reporting or compliance steps under Canadian chemical regulations.
