Background

The purpose of this document is to inform registrants, pesticide regulatory officials and the Canadian public of the re-evaluation and special review work (in other words, the post-market reviews) planned by Health Canada's Pest Management Regulatory Agency (PMRA) for the next five fiscal years from 1 April 2025 to 31 March 2030. This document presents updates to the information last published in Re-evaluation Note REV2024-01, Pest Management Regulatory Agency Re-evaluation and Special Review Work Plan 2024-2029.

Health Canada regulates pesticides in Canada, with the primary objective of protecting the health of Canadians and the environment. A pesticide product may only be sold or used in Canada if it has been registered or otherwise authorized under the authority of the Pest Control Products Act. Health Canada uses a rigorous science-based risk assessment approach to ensure that the product meets health and environmental protection standards and has value.

As part of the post-market program, registered pesticides are re-evaluated on a cyclical basis to determine their continued acceptability. Pesticides may also be re-evaluated as a result of changes in the information required or the procedures used by Health Canada to determine that the pesticide meets current health, environment and value standards. The re-evaluation process is described in Regulatory Directive DIR2016-04, Management of Pesticides Re-evaluation Policy. In addition, a special review may be initiated at any time to address the identified aspect(s) of concern, and a special review is triggered only under certain circumstances. Special reviews differ from re-evaluations in that a special review is intended to examine only specific aspects of a pesticide. Additional information on special reviews can be found in the PMRA Guidance Document, Approach to Special Reviews of Pesticides.

As required under the Pest Control Products Act, Health Canada publishes all post-market proposed decisions for public consultation. Following consultation, comments and information submitted by the public and other stakeholders are considered before Health Canada issues a final decision. Stakeholders are encouraged to stay informed of upcoming consultations and decisions for pesticides by visiting the Pesticides and pest management section of Canada.ca.

This work plan includes the target dates for the proposed and final decisions to be published from 1 April 2025 and the status of all open re-evaluations and special reviews. In addition, new re-evaluations expected to be initiated from 1 April 2025 to 31 March 2030 are included for improved transparency for registrants and stakeholders.

This five-year work plan may change in response to workload and emerging issues that require priority action. During the course of the year, interested stakeholders can monitor the PMRA's Public Registry to view the announcement of new re-evaluations and special reviews, as well as other documents relevant to specific post-market reviews.

Work plan development

The re-evaluation and special reviews of several actives included in last year's plan (REV2024-01) have been carried over to this fiscal year due to the complex nature of the re-evaluations and the need to review large volumes of data and extensive use patterns. Resources were also focused on other priorities including an increased number of pre-market notices of objection and special review initiations. The number of re-evaluation initiations required as per the 15-year legislative requirement continues to be high and, given the current resource capacity considerations, the backlog is growing.

The PMRA's Continuous Oversight Model and Proportional Effort Framework will support operations and render them more efficient to ensure that the PMRA responds to emerging risks in a more timely manner and that the limited scientific resources are focused on issues that matter most. The PMRA consulted on the Proposed Continuous Oversight Policy (PRO2024-01) in 2024. Over the course of the year, the PMRA plans to publish the policy on Continuous Oversight and begin implementing it. Future implementation of the proportional effort policy following consultation will enable the PMRA to better focus review efforts to increase overall protection and make progress to eliminate the re-evaluation backlog. Finally, Health Canada will seek independent scientific advice on post-market reviews through the Science Advisory Committee, when necessary, to better inform its evidence-based decisions.

The following Tables outline the target publication dates for the proposed and final decisions of special reviews and re-evaluations established based on the currently available resources. In addition, next milestone target dates for the three standalone quantitative cumulative health risk assessments initiated are also included.

Part A: Special reviews

Special reviews are very focused and examine only specific aspects of a pesticide as outlined in PMRA Guidance Document, Approach to Special Reviews of Pesticides. While the aspect of concerns for each special review is included in the special review announcement available in the Public Registry, they are captured in the table below for easy access.

Part C: Re-evaluations – Early stage of re-evaluation process

The re-evaluations of the following active ingredients are in the early stage of the re-evaluation process. The PMRA will focus on the scoping reviews of these actives to determine the re-evaluation categories. Table 1 is the list of actives targeted first. The outcome of the scoping reviews will further inform prioritization of active ingredients for review phase, and the expected timelines for their public consultation will be included in the work plan to be published in spring 2026.
