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 2024 to 31 March 2029.
This work plan includes the target dates for the proposed and final decisions to be published since 1 April 2024, the status of all open re-evaluations and special reviews, as well as new re-evaluations expected to be initiated from 1 April 2024 to 31 March 2029. This document presents updates to the information last published in Re-evaluation Note REV2023-01, Pest Management Regulatory Agency Re-evaluation and Special Review Work Plan 2023-2028.
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 five-year work plan may change in response to workload and emerging issues that require priority action. While this work plan will be updated annually, 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.
Part A – Current re-evaluation and special review work plan (Tables 1–3)
The post-market review program workload remains significant. In recent years, Health Canada focused its resources on the completion of the remaining older pesticide active ingredients registered before 1995, and completed their re-evaluation by 31 March 2023. Health Canada introduced the risk based prioritization for the re-evaluation program in 2019 (REV2020-01), and ongoing efforts to streamline the re-evaluation processes for lower priority actives resulted in the removal of the backlog of lower priority actives. The re-evaluation reviews of several higher priority actives have been delayed due to the demands of focusing resources on completing the re-evaluations of older pesticides, and other priorities including responding to litigations, as well as notices of objection, and the scientific complexity associated with certain pesticide reviews. The number of re-evaluation initiations currently required as per the 15-year legislative requirement continues to be high and given the current resource capacity considerations, the backlog is growing.
As part of its Transformation Agenda (PMRA Transformation), the PMRA is building upon existing risk prioritization efforts to develop a proportional effort approach that prioritizes workload across the full pesticide program. Implementation of proportional effort will enable the PMRA to better focus review efforts to increase overall protection and make progress to eliminate the re-evaluation backlog. The proportional effort policy is expected to be issued for public consultation in mid-summer 2024. Future work plans will reflect any new prioritization or timelines, once the proportional effort policy is finalized.
In addition to proportional effort, the PMRA has recently consulted on the continuous oversight lifecycle approach (Proposed Continuous Oversight Policy) that enhances our ability to keep pace with new science information and takes necessary action where needed to protect human health and the environment. A final continuous oversight approach taking into consideration the comments received during consultation is expected to be issued in late Spring 2024. Continuous oversight reduces reliance on the re-evaluation program by identifying and addressing risks sooner thereby decreasing the complexity of re-evaluation reviews.
During the post-market reviews, when necessary, Health Canada will seek independent scientific advice through Science Advisory Committee to better inform its evidence-based decisions.

Part A, Table 3 Re-evaluation Initiations between 1 April 2024 and 31 March 2025
For the re-evaluation initiations between 1 April 2024 to 31 March 2025, risk-based prioritization of actives as higher or lower priority based on the risk prioritization approach implemented since 2019 (REV2020-01) was not conducted. As part of the PMRA's transformation initiative, a proportional effort policy is expected to be issued for consultation in mid-summer 2024, and prioritisation of re-evaluations initiated from 1 April 2024 onwards will be part of this proportional effort approach.
To further improve transparency for stakeholders and registrants, specific month of initiation of re-evaluation is included.
