Health Canada Proposes Cancellation of All Uses of Chlorpyrifos

On May 31, 2019, Health Canada’s Pest Management Regulatory Agency (PMRA) issued its Proposed Re-evaluation Decision PRVD2019-05, Chlorpyrifos and Its Associated End-use Products: Updated Environmental Risk Assessment (Updated Environmental Risk Assessment).  PMRA states that this re-evaluation “considers data and information from pesticide manufacturers, published scientific reports, and other regulatory agencies” and that “Health Canada applies internationally accepted risk assessment methods as well as current risk management approaches and policies.”

PMRA is proposing the cancellation of most uses of chlorpyrifos, including almost all agricultural uses, due to PMRA’s belief that they pose unacceptable risks to the environment.  The proposal would allow a small number of uses to continue if certain label changes are made.  More specifically, PMRA states that its evaluation of available scientific information “has not found acceptable risks to beneficial arthropods, birds, mammals and all aquatic biota in the environment for most current chlorpyrifos uses” but “[g]reenhouse ornamental, outdoor ornamentals (container stock only) for control of Japanese beetle larvae, indoor and outdoor structural, adult and larval mosquito uses of chlorpyrifos have been shown to be acceptable from the environmental perspective.”  The label changes that PMRA states would be required for these uses to continue include the following:  (1) standard environmental hazard statements to inform users of the potential toxic effects to non-target species; and (2) standard environmental advisory statements for prevention of contamination of aquatic systems and to reduce volatilization.

There is a 90-day public consultation period on the proposal, which began on May 31, 2019, during which the public may submit written comments and additional information to PMRA.  PMRA states that the public may submit additional information that could be used to refine risk assessments and that the final re-evaluation decision will take into consideration the comments and information received during the comment period, which could result in revised risk mitigation measures.  The re-evaluation decision document will include the final re-evaluation decision, the reasons for it, and a summary of comments received on the proposed re-evaluation decision with Health Canada’s responses.
