Special Review Decision

Pursuant to subsection 17(2) of the Pest Control Products Act, the Pest Management Regulatory Agency (PMRA) conducted a special review of pest control products containing dichlobenil based on the European Decision (European Commission, 2011a) and the Norwegian Decision (Rotterdam Convention, 2000) to prohibit the use of this active ingredient due to environmental concerns. The PMRA 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 consultation in the Re-evaluation Note REV2016-15, Special Review of Dichlobenil: Proposed Decision for Consultation, and it outlines the Agency's proposed decision and the reasons for it.

No comments were received during the consultation process. The PMRA, under the authority of the Pest Control Products Act, is confirming the current registration of pest control products containing dichlobenil in Canada. Label amendments are required to meet the current labelling standard and to standardize statements across labels (Appendix I).

Regulatory Directive DIR2014-01, Approach to Special Reviews, presents the details of the PMRA's special review approach.

To comply with this decision, the required label changes must be implemented on all products labels sold by registrants no later than 24 months after the publication date of this document. Registrants of the products containing dichlobenil will be informed of the specific requirements affecting their product registration(s) and of the regulatory options available to them.
