Permit for Fluorinated 1‑Hexene

Summary#

The government has issued Ministerial Condition No. 22186 that lets a specific notifier manufacture or import 1-hexene, 3,3,4,4,5,5,6,6,6-nonafluoro- (CAS RN 19430-93-4) in Canada, but only if they follow a set of conditions. The ministers say they suspect the substance may be harmful, so the permission comes with reporting, record-keeping and release-response rules that came into force on June 17, 2025.

What it does#

• Under the Canadian Environmental Protection Act, 1999, the Minister permits the manufacture or import of the listed substance, but only under the conditions in the annex.
• Who may use the permission:
  • The person who provided the required information on April 22, 2025 (called the “notifier”) may manufacture or import the substance, subject to these conditions.
• Before starting manufacturing in Canada the notifier must, at least 120 days beforehand, inform the Minister in writing and provide:
  • the anticipated annual quantity to be manufactured;
  • the address of the Canadian manufacturing facility;
  • exposure information, including:
    • expected modes of transportation and storage;
    • size and type of containers used for transport and storage;
    • which parts of the environment might receive releases;
    • anticipated releases into municipal wastewater systems;
    • recommended destruction or disposal methods;
    • historical and likely uses; and
    • any factors that may limit environmental exposure;
  • details about the manufacturing process, including precursors, reaction stoichiometry, whether the process is batch or continuous and its scale; a process flow diagram; and descriptions of major steps and points where releases could occur; and
  • a summary of all other information and test data the notifier has that identify hazards and expected exposure.
• If the substance or waste containing it is released to the environment:
  • the notifier must immediately stop further release and limit dispersion; and
  • the notifier must notify an enforcement officer or the provincial/territorial 24‑hour emergency telephone service as soon as circumstances allow.
• Before giving the substance to anyone else, the notifier must:
  • inform that person in writing of these ministerial conditions; and
  • get written confirmation from that person that they were informed, before the first transfer.
• Record-keeping requirements for the notifier:
  • keep records showing use and quantities manufactured, imported, purchased, distributed, sold and used; the names and addresses of recipients; and the written confirmations from recipients;
  • create records no later than 30 days after the information becomes available and update recipient address changes within 30 days of learning of them;
  • keep records in English, French, or both at the notifier’s principal place of business in Canada (or their Canadian representative’s) for at least 5 years; electronic records must be in a readable format.
• The conditions came into force on June 17, 2025.

Who's affected#

• The primary permit holder is the unnamed person who submitted information on April 22, 2025 (the “notifier”). The public notice does not list that person by name.
• Any company or person who receives physical possession of the substance from the notifier will be affected because they must be told about the conditions and confirm in writing.
• People living or working near a potential manufacturing site, municipal wastewater operators, and environmental responders could be affected in practice, since the rules focus on preventing and reporting releases and on disposal methods.
• It is unclear from the notice whether other companies (besides the notifier) may also obtain permission to manufacture or import the substance under these or other conditions.

Why it matters#

• The government believes the substance may be harmful to people or the environment. These conditions aim to limit releases, improve tracking, and ensure the government can respond quickly to any environmental release.
• The notification and record rules give regulators advance notice about where and how much of the substance will be made. That helps local emergency planners and wastewater managers prepare.
• The transfer and record‑keeping rules create a paper trail so the substance’s movement and use can be traced for at least 5 years.
• The notice does not ban the substance. Instead, it lets one notifier proceed under strict reporting and safety rules.
