  • 19531-9 — Hexanedioic acid, polymer with (chloromethyl)oxirane, ethyl(hydroxymethyl)alkanediol, (alkylalkylidene)bis[phenol] and oxirane, 2-propenoate
  • 19586-4 — Alkanoic acid, compds. with bisphenol A-epichlorohydrin polymer-hydrolyzed N-(1,3-dimethylbutylidene)-N’-[2-[(1,3-dimethylbutylidene)amino]ethyl]-1,2-ethanediamine-2-(methylamino)ethanol reaction products
  • 19587-5 — 2-Propenoic acid, polymer with α-(methylalkenyl)-ω-hydroxypoly(oxy-1,2-ethanediyl), graft
  • 19588-6 — 2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene, ethyl 2-propenoate, 2-oxiranylmethyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate), reaction products with diethanolamine, alkanoates (salts)
  • 19589-7 — Metal, bis(2,4-pentanedionato-kO2,kO4)-, (T-4)-
  • 19590-8 — Siloxanes and Silicones, di-Me, hydroxy-terminated, mixed ethers with polyalkylene glycol monoalkyl ether and polyalkylene glycol monoalkyl ether
• States that the Order comes into force on the day it was registered (i.e., April 25, 2022).

Who's affected#

• Chemical manufacturers and importers that make, sell, or bring the listed substances into Canada.
• Companies that use those substances in products or industrial processes (downstream users).
• Laboratories, formulators, and suppliers who handle or label chemical products containing these substances.
• Government regulators and environmental groups that track which substances are present in Canadian commerce.
• If it’s unclear whether a particular business is affected, that business should check whether it deals with any of the listed CAS numbers.

Why it matters#

• Being added to the Domestic Substances List means these substances are now formally listed as existing in Canada. That can change how they are treated under federal chemical rules, including whether they are considered “new” for certain notification or assessment steps.
• For businesses, listing can affect reporting, import or manufacture obligations, and planning for compliance.
• For the public and regulators, additions update the pool of chemicals to be tracked for health and environmental assessment.
• The order itself does not explain all downstream regulatory effects; for details on how listing affects specific obligations, consult Environment and Climate Change Canada guidance or the regulatory analysis linked to the order.
