The purpose of this document is to provide registrants, pesticide regulatory officials and the Canadian public with an update on the status of re-evaluations and special reviews, listed in documents such as Re-evaluation Notes REV2012-13, Update on the Pest Management Regulatory Agency Re-evaluation Initiation Schedule and REV2011-05 Re-evaluation of Pyrethroids, Pyrethrins and Related Active Ingredients. Special reviews of various chemicals are also being conducted. Please see Re-evaluation Notes REV2013-06, Special Review Initiation of 23 Active Ingredients and REV2014-06, Initiation of Special Reviews: Potential environmental risk related to Peponapis pruinosa exposure to Clothianidin, Imidacloprid and Thiamethoxam used on cucurbits.

Health Canada’s Pest Management Regulatory Agency (PMRA) is concurrently engaged in various planned activities for active ingredients (and associated products) within the re-evaluation program, for example, re-evaluation of active ingredients in the current program (such as cyclical re-evaluations, pyrethroids and neonicotinoid pollinator assessment), active ingredients remaining from the previous program (Regulatory Directive DIR2001-03, PMRA Re-evaluation Program) and special reviews, as well as addressing confirmatory studies that were required as a result of previous re-evaluation decisions.

As a result, resources have been prioritized in order to complete certain key documents for each of these activities. This is expected to affect progress on some of the re-evaluations in the current program, as noted below.

PMRA has also published a summary of the re-evaluation work plan for 2015-2018 (REV2015‑05, Pest Management Regulatory Agency Re-evaluation Work Plan 2015-2018). Please refer to that work plan for target years for the re-evaluations or special reviews noted in Tables 1 and 2 as being “in progress”.

Table 1 presents the current re-evaluation status, as of 1 May 2015, for the chemicals listed in re‑evaluation notes REV2012-13 and REV2011-05.

In addition to the above, re-evaluations of several active ingredients remaining from the previous program (Regulatory Directive DIR2001-03) currently have documents in the publications process. These active ingredients are: chlorothalonil (updated proposed re‑evaluation decision), dimethoate (final re-evaluation decision), methomyl (proposed re‑evaluation decision) and aluminum/magnesium phosphide and phosphine gas (final re‑evaluation decision). Where appropriate, their next steps will be included in the re-evaluation work plan for 2015-2018 (REV2015-05).

Table 2 presents the status, as of 1 May 2015, for the active ingredients (and associated products) currently under special review (see re-evaluation notes REV2013-06 and REV2014-06).
