The purpose of this document is to provide an in depth view into the stages to release data and information, in the interest of transparency and Open Government within the RCMP.

Pentachlorophenol is currently registered for industrial uses as a heavy duty wood preservative in Canada. All currently registered pest control products containing pentachlorophenol are considered in this special review (Appendix I of PSRD2020-03).

Before making a special review decision on pymetrozine, Health Canada will consider all comments received from the public in response to PSRD2020-04. A science-based approach will be applied in making a final decision on pymetrozine. Health Canada will then publish a special review decision document, which will include the decision, the reasons for it, a summary of the comments received on the proposed decision, and Health Canada’s response to these comments.

Based on the assessment of the aspects of concern under subsection 17(1) and subsection 17(2) of the Pest Control Products Act, Health Canada’s Pest Management Regulatory Agency, under the authority of the Pest Control Products Act, is confirming the current registration of pymetrozine products for sale and use in Canada with risk mitigation measures (Appendix III). All pest control products containing pymetrozine that are registered in Canada are subject to the special review decision.

Before making a final decision on the special reviews of clothianidin, thiamethoxam and imidacloprid used on cucurbits and their potential risk to squash bees, Health Canada will consider all comments received from the public in response to this consultation document. A science-based approach will be applied in making a final decision on these special reviews. Health Canada will then publish a special review decision document, which will include the decision, the reasons for it, a summary of the comments received on the proposed decision, and Health Canada’s response to these comments.

Evaluation of available scientific information related to the aspect of concern indicated that the potential environmental risks to Eucera pruinosa (squash bee) through exposure to clothianidin, thiamethoxam and imidacloprid used on cucurbits are considered acceptable when used according to the current conditions of use.

Before making a final decision on the special review of iprodione, Health Canada will consider all comments received from the public in response to this consultation document. Health Canada will then publish a special review decision document, which will include the decision, the reasons for it, a summary of the comments received on the proposed decision, and Health Canada's response to these comments.

Iprodione is a contact fungicide registered for commercial uses in Canada. Re-evaluation of iprodione was completed in 2018 (Re-evaluation Decision RVD2018-16, Iprodione and Its Associated End-use Products), and continued registration is granted with additional risk mitigation measures. Currently registered products containing iprodione are listed in Appendix I.

With respect to human health, dietary risks (food alone and food plus water) were not shown to be acceptable for food uses when chlorothalonil is used according to current conditions of registration. Based on this, all food uses of chlorothalonil are proposed for cancellation and all maximum residue limits (MRLs) are proposed for revocation.
Environmental risks to aquatic organisms were not shown to be acceptable for all outdoor uses when chlorothalonil is used according to current conditions of registration.

Health Canada has determined that continued registration of products containing chlorothalonil is acceptable with mitigation measures. An evaluation of available scientific information found that the material preservative uses of chlorothalonil meet current standards for protection of human health and have acceptable value when used according to revised conditions of registration, which includes new mitigation measures. Environmental exposure from the material preservative uses of chlorothalonil is expected to be minimal.
