Special review decision

Pursuant to subsection 17(2) of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) initiated a special review of all registered pest control products containing linuron. This special review was based on the decision taken by Norway in 2007 to prohibit the use of linuron due to human health and environmental concerns, and the decision taken by the European Union (EU) in 2017 to prohibit the use of linuron due to human health and environmental concerns.

Health Canada evaluated the aspects of concern that prompted the special review in accordance with subsection 18(4) of the Pest Control Products Act. The proposed special review decision was published for consultationFootnote 1 in the Proposed Special Review Decision PSRD2020-05, Special Review for Linuron and Its Associated End-use Products. No comments were received during the consultation period.

Linuron is an herbicide registered for commercial use in Canada. Re-evaluation of linuron was completed in 2020 (Re-evaluation Decision RVD2020-10, Linuron and its associated end-use products), and continued registration is granted for uses on carrots, parsnip, potato, asparagus, and shelterbelts with additional risk mitigation measures. Currently registered pest control products containing linuron are listed in Appendix I.

Following an evaluation of the aspects of concern, Health Canada has determined that continued registration of products containing linuron is considered to be acceptable with the risk mitigation measures and label amendments outlined in RVD2020-10. A summary of the label amendments that are relevant for the special review are included for information in Appendix II. Therefore, Health Canada, under the authority of the Pest Control Products Act, is confirming the current registration of pest control products containing linuron in Canada, with revised label directions as outlined in RVD2020-10. No additional risk mitigation measures are required.

All pest control products containing linuron that are registered in Canada are subject to this special review decision.
