1-Bromopropane: Proposed Restrictions

Summary#

Two Environment notices are published. First, a short report on comments about new federal–provincial–territorial “environmental occurrences notification agreements” says only one public comment was received and no changes were made. Second, a health and environment assessment of four alkyl halide chemicals finds that 1‑bromopropane may be a danger to human health and sets out proposed next steps, with a public comment period from April 25, 2026 to June 24, 2026.

What it does#

• Reports on the environmental occurrences notification agreements:

  • Confirms these agreements were developed by Environment and Climate Change Canada with several provincial and territorial governments.
  • Says the agreements create a faster way for federal and provincial/territorial governments to notify and share information about environmental incidents.
  • Makes clear the agreements do not create legal duties to notify or direct municipal services, animal shelters, or non‑government groups; one public suggestion asking that shelters be notified was not acted on.

• Publishes the assessment summary of four substances (the Alkyl Halides Group) under the Canadian Environmental Protection Act, 1999:

  • Concludes 1‑bromopropane meets CEPA’s test for posing a danger to human health.
  • Proposes that the ministers recommend adding 1‑bromopropane to Part 2 of Schedule 1 and to regulate or restrict its use in certain sprays and flush products (silicone mould release spray, electrical equipment cleaner spray, textile ink remover spray, and automotive A/C flush).
  • Releases a risk management approach for 1‑bromopropane and asks for public comments for 60 days (comments accepted April 25, 2026 to June 24, 2026).
  • States that bromoethane, chloroethane, and trans‑1,2‑dichloroethene do not meet CEPA criteria and no further action is proposed for them at this time.

Who's affected#

• People who work with or use products that can contain 1‑bromopropane:
  • Industrial and maintenance workers using silicone mould release sprays, electrical‑equipment cleaners, textile ink removers, and automotive A/C flush.
  • Employers, product manufacturers, importers and retailers of those products.
• General public who might be exposed to these chemicals through indoor air or product use.
• Provincial and territorial governments involved in the notification agreements; municipal first‑responders, animal shelters and NGOs are not made parties to these agreements and therefore are not given new legal duties by them.
• Stakeholders who want to comment on the risk management approach for 1‑bromopropane during the public comment window (April 25, 2026–June 24, 2026).

Why it matters#

• If ministers move forward, 1‑bromopropane could face federal restrictions or regulation. That could change what products are available, require safer workplace controls, or force reformulation by manufacturers.
• Workers and businesses that handle these products may need to plan for new controls, training, or replacement products.
• The notification agreements make it clearer how federal and provincial/territorial governments will share information after environmental incidents, but they do not shift responsibilities to municipalities or animal shelters — local emergency plans remain the place for that coordination.
• There is an active chance to comment: officials are asking for feedback on how to manage 1‑bromopropane before regulations are proposed.
