Conditions for Three Chemicals; Pigs Consultation

Summary#

The federal environment department published several ministerial conditions under the Canadian Environmental Protection Act, 1999 that allow the manufacture or import of three specific chemical substances but only under set limits and handling rules. It also opened a public consultation on four lines of gene-edited pigs notified by Genus PLC, with comments accepted from June 20 to July 20, 2025.

What it does#

• Ministerial Condition No. 21194a varies earlier conditions for the substance carbopolycycle, acid-treated, oxidized, Confidential Accession Number 19612-0:
  • Allows manufacture or import only as a precursor to make a silver-doped version, with limited transfers allowed for use as additives in concrete (up to 1% by weight), fuels, or anti‑corrosion/icephobic products under strict use conditions.
  • Requires no releases to the environment when used for the allowed precursor purpose; waste must be incinerated or sent to an engineered hazardous waste landfill.
  • Sets written notification and record-keeping rules for transfers and disposal.
  • Comes into force on May 20, 2025.
• Ministerial Condition No. 22068 permits manufacture or import of 2H-isoindole-2-hexaneperoxoic acid, 1,3-dihydro-1,3-dioxo-, CAS 128275-31-0, but bans its use in most cosmetics except with strict concentration limits:
  • Allowed in toothpaste or tooth powder at ≤ 0.11% by weight.
  • Allowed in mouthwash at ≤ 0.27% by weight.
  • Allowed in tooth whitening products at ≤ 1.2% by weight.
  • Not allowed in diapers or sanitary napkins.
  • Requires written warnings to recipients and record-keeping.
  • Comes into force on May 23, 2025.
• Ministerial Condition No. 22160 permits manufacture or import of a specific triazine (CAS 69004-04-2) with pre-manufacture reporting requirements:
  • The notifier must inform the minister at least 120 days before starting manufacture in Canada and provide details on expected quantities, facility address, transportation/storage, release pathways, disposal methods, and other exposure information.
  • Requires incident reporting and record-keeping.
  • Comes into force on March 26, 2025.
• A consultation notice under the New Substances Notification Regulations (Organisms) invites public comments on assessments of four lines of gene-edited pigs described as resistant to porcine reproductive and respiratory syndrome virus. This consultation is required by amendments from Bill S-5.

Who's affected#

• Chemical manufacturers, importers, and suppliers dealing with the three named substances.
• Companies that make or sell:
  • concrete and cement-based composites,
  • fuels,
  • anti‑corrosion or icephobic coatings,
  • toothpaste, mouthwash, and tooth‑whitening cosmetics.
• Waste handlers and hazardous-waste landfills or incinerators that may receive material from these substances.
• Genus PLC, pig breeders, livestock producers, animal-health researchers, and anyone with an interest in gene-edited animals (regulators, Indigenous communities, environmental and animal‑welfare groups).
• The general public who use consumer products listed above may be affected indirectly through product formulations, though the notices mostly target industry and not consumers directly.

Why it matters#

• These notices show the government is allowing controlled use of certain substances it suspects could be harmful, while putting limits on how they’re used, stored, transferred, and disposed of. That aims to reduce environmental releases and keep potentially risky materials out of consumer items or waste streams unless tightly controlled.
• The concentration limits for toothpaste, mouthwash and whitening products could change product formulations or sourcing decisions for oral-care companies.
• The pre-manufacture reporting rule for the triazine gives regulators a heads-up about new domestic manufacturing and expected environmental exposure.
• The gene-edited pigs consultation gives the public and stakeholders a formal chance to comment on the planned introduction of modified animals into Canada before the assessment is completed.
