Domestic Substances List Additions

Summary#

This Order, Order 2022-87-01-01 Amending the Domestic Substances List (SOR/2022-12), adds a set of chemical substances to the Domestic Substances List. It was registered on February 2, 2022 and published in the Canada Gazette on February 16, 2022. The Order was signed by Steven Guilbeault on January 31, 2022.

What it does#

• Adds the following CAS numbers to Part 1 of the Domestic Substances List:
  • 870-08-6
  • 1889-67-4
  • 10101-50-5
  • 169501-66-0
  • 474795-79-4
  • 1684433-82-6
  • 2502116-61-0
  • 2648350-43-8
• Adds the following entries to Part 3 of the Domestic Substances List (CAS numbers and their chemical names):
  • 19576-4 — 2-Propenoic acid, 2-methyl-, polymer with alkyl 2-methyl-2-alkenoate, ammonium salt, tert‑Bu hydroperoxide‑initiated
  • 19577-5 — Hexanedioic acid, polymers with acrylic acid‑dipentaerythritol reaction products, adipic acid dihydrazide, 3‑hydroxy‑2‑(hydroxymethyl)‑2‑methylpropanoic acid, 5‑isocyanato‑1‑(isocyanatomethyl)‑1,3,3‑trimethylcyclohexane, neopentyl glycol and polyalkylene glycol 2,2‑bis(hydroxymethyl)butyl Me ether
  • 19580-8 — Propanoic acid, 3‑hydroxy‑2‑(hydroxymethyl)‑2‑methyl‑, polymer with dialkyl carbonate, 1,6‑hexanediol, 5‑isocyanato‑1‑(isocyanatomethyl)‑1,3,3‑trimethylcyclohexane, 1′1‑methylenebis[4‑isocyanatocyclohexane] and 2‑oxepanone, polyethylene glycol mono‑Me ether blocked, compds. with triethylamine
• The Order states it comes into force on the day it is registered (the registration date above).

Who's affected#

• Companies that manufacture or import any of the listed substances into Canada.
• Chemical suppliers, industrial users, and possibly downstream product makers who use these substances.
• Federal regulators who keep track of which substances are present in Canadian commerce.
  If it’s unclear whether a particular business or product is affected, the Order itself lists the specific CAS numbers and chemical names to check against.

Why it matters#

• Being added to the Domestic Substances List means these exact substances are now officially listed as present in Canadian commerce.
• For businesses, that can change which federal chemical rules and reporting requirements apply — because different rules apply to substances that are listed versus those that are not.
• For the public and regulators, the listing updates the official inventory the government uses to track and assess chemicals in Canada.
