Conditional permit for fluorinated 1-hexene

Summary#

This notice records Ministerial Condition No. 22186 under the Canadian Environmental Protection Act, 1999. It allows the person who filed information on April 22, 2025 (the “notifier”) to manufacture or import the chemical 1-hexene, 3,3,4,4,5,5,6,6,6-nonafluoro- (CAS 19430-93-4) in Canada, but only if they follow a set of reporting, safety and record‑keeping conditions that took effect on June 17, 2025.

What it does#

• Confirms that the Minister of the Environment and Minister of Health have concerns the substance may be toxic, but permits manufacture or import for the notifier under specific conditions.
• Requires the notifier to give written notice to the Minister at least 120 days before starting to manufacture in Canada, including:
  • anticipated annual quantity and address of the facility;
  • details about how the substance will be transported and stored (containers, modes);
  • where releases might go (air, water, soil, municipal wastewater) and disposal or destruction methods;
  • likely uses and any factors that limit environmental exposure.
• Requires details about the manufacturing process, including a process flow diagram and points where releases could occur and how they will be avoided.
• Requires the notifier to summarize any existing test data or other information they hold about hazards and exposures.
• If any release to the environment happens, the notifier must immediately stop further release, limit spread, and notify an enforcement officer or the listed 24‑hour provincial/territorial emergency contact as soon as possible.
• Before giving the substance to anyone else, the notifier must:
  • inform that person in writing of these ministerial conditions; and
  • obtain written confirmation that the person was informed, before the first transfer.
• Record-keeping rules: the notifier must keep electronic or paper records showing use and quantities (manufactured, imported, purchased, distributed, sold, used), names and addresses of recipients, and the written confirmations. Rules include:
  • update recipient address records within 30 days of learning of a change;
  • create records no later than 30 days after the information becomes available;
  • keep records in English and/or French at the notifier’s Canadian principal place of business for at least five years; electronic records must be readable.

Who's affected#

• Primarily the notifier — the person or company that supplied the required information on April 22, 2025 and is named in the conditions. The ministerial conditions explicitly apply to that notifier.
• Any person or business who receives the substance from the notifier (they must be told about the conditions and confirm in writing).
• It is unclear from this notice whether other companies that were not the notifier are covered or automatically allowed to manufacture or import the same substance; the document applies directly to the notifier only.

Why it matters#

• The government is allowing controlled manufacture/import of a chemical suspected to be harmful, while requiring information, controls and record-keeping to reduce and track environmental and human exposure.
• The rules force the notifier to plan ahead (notice 120 days before manufacturing), show how it will limit releases, and to report and respond quickly if any release occurs. That can reduce pollution risks for nearby communities and for municipal wastewater systems.
• Records and transfer notifications make it easier for regulators and downstream users to know who has the chemical and how it was handled, which helps enforcement and public safety.
