1‑Bromopropane Controls and Notification Agreements

Summary#

Two items from the Department of the Environment were published on April 25, 2026. One reports on public comments about new federal–provincial notification agreements for environmental incidents and says no changes were made. The other publishes a health and environment assessment of four alkyl halide chemicals and proposes action on 1‑bromopropane while taking no further action on the other three substances.

What it does#

• Environmental-occurrences notification agreements

  • Describes a streamlined system for sharing notifications and information about environmental incidents between Environment and Climate Change Canada and several provinces and territories (Ontario, Manitoba, British Columbia, Saskatchewan, Alberta, and Yukon).
  • Notes one public comment asking that municipal animal shelters, humane societies, SPCAs and wildlife rehabilitators be notified immediately of spills.
  • Explains the agreements do not create legal duties to notify or direct municipal services or non‑governmental groups. No substantive changes were made in response.

• Assessment of the Alkyl Halides Group (four substances)

  • Publishes the assessment findings under the Canadian Environmental Protection Act, 1999 for:
    • 1‑bromopropane
    • bromoethane
    • chloroethane
    • trans‑1,2‑dichloroethene
  • Concludes 1‑bromopropane may pose a danger to human health. The Minister of the Environment and the Minister of Health propose to recommend adding it to Part 2 of Schedule 1 of the Act and to regulate or otherwise restrict its use in:
    • silicone mould release spray
    • electrical equipment cleaner spray
    • textile ink remover spray
    • automotive air conditioning flush
  • Releases a risk management approach document and invites public comment on that approach.
  • States that bromoethane, chloroethane, and trans‑1,2‑dichloroethene do not meet the Act’s criteria now, so no further action is proposed for them at this time.
  • Public comment period on the risk management approach: April 25, 2026, to June 24, 2026. Comments can be sent by email or through Environment and Climate Change Canada’s online Single Window. People may ask that information they provide be treated as confidential.

Who's affected#

• Companies that make, import, sell or use 1‑bromopropane or products that list it (for example manufacturers of sprays and degreasers).
• Workers in shops or industries that use the listed spray products. Workplace exposures were a key part of the health assessment.
• Consumers who buy or use products that contain these chemicals.
• Chemical suppliers, downstream product formulators, and occupational health regulators.
• Federal, provincial and territorial environment and emergency management offices (they will use the notification agreements).
• Municipal animal shelters, humane societies and wildlife rehabilitators may be concerned, but the published agreements do not require governments to notify them automatically.

Why it matters#

• If 1‑bromopropane is added to Schedule 1 and regulated, some spray products may face new restrictions or changes in labelling and use. That can affect product availability and workplace controls.
• The published risk management approach and the comment period (ending June 24, 2026) give industry, workers and members of the public a chance to influence how any controls would work.
• The notification agreements are meant to speed information-sharing between governments after environmental incidents. That can improve government response, but it does not by itself guarantee that local animal shelters or NGOs will be told about a spill.
