Canada: Bill C-31 Pest Control Products Act Amendments Weaken Pesticide Oversight

• Bill C-31 proposes amendments to Canada's Pest Control Products Act, specifically Section 13.
• Section 13 would eliminate mandatory 15-year reassessments of registered pesticides by Health Canada.
• Instead, reviews would rely on existing information, triggering full reassessment only if risks "increased significantly."
• A coalition of farmers, victims, and environmental groups opposes these changes, citing concerns over transparency and scientific rigor.
• Critics argue the amendments conflict with Canada's international biodiversity commitments and existing Bill C-30 override powers.

This enacted Bill C-30 pesticide override powers mechanism, combined with the proposed changes in Bill C-31, suggests a potential erosion of science-based decision-making in pesticide regulation.

A significant legislative proposal, Bill C-31, is currently under scrutiny in Canada, aiming to introduce substantial amendments to the Pest Control Products Act. Central to these proposed changes is Section 13, which seeks to eliminate the existing requirement for mandatory, periodic reassessments of registered pesticides. This move has sparked considerable opposition from a broad coalition comprising farmers, individuals affected by pesticide exposure, and various health and environmental organizations.

This coalition has publicly urged Parliament to remove Section 13 from the bill, arguing that these Bill C-31 Pest Control Products Act amendments would fundamentally weaken federal oversight of pesticides. Their concerns were voiced at a press conference held in Ottawa, coinciding with the legislation's ongoing review by the House of Commons Standing Committee on Finance. Notably, the proposed measure has also drawn criticism from the Senate, highlighting widespread apprehension regarding these Canada pesticide regulation changes.

Under the current framework of the Pest Control Products Act, Health Canada is mandated to conduct comprehensive reassessments of all registered pesticides at least once every 15 years. These evaluations are crucial, as they require the application of the most up-to-date scientific evidence to ensure ongoing safety. However, Section 13 of Bill C-31 proposes a significant departure from this established practice. Instead of mandatory reassessments, it would introduce a system based on reviewing "available information," with a full reassessment only triggered if risks are determined to have "increased significantly."

The coalition opposing these changes has articulated three primary concerns regarding this new approach to Health Canada pesticide reassessment. Firstly, they point to the absence of a clear definition for what constitutes a "significantly increased risk," which could lead to arbitrary interpretations. Secondly, the proposed reviews would be limited to information already at hand, unlike the current mandatory reassessments that empower Health Canada to demand new scientific data from registrants. Finally, critics highlight a lack of transparency, as the amendments would require public disclosure of reasons only when a review *does* trigger a reassessment, but not when it concludes that no further action is needed. This selective transparency raises questions about accountability in the Canadian pesticide regulation changes.

Beyond the immediate operational changes, the proposed amendments carry broader implications for Canada's environmental commitments and existing regulatory landscape. Opponents contend that weakening pesticide oversight would directly conflict with Canada's pledge under the Kunming-Montreal Global Biodiversity Framework, which aims to halve the overall risks associated with pesticides and highly hazardous chemicals by 2030. This underscores a tension between domestic legislative proposals and international environmental obligations.

Further compounding these concerns are existing provisions, notably those enacted through Bill C-30, which now grant the Cabinet the authority to override scientific determinations of unacceptable pesticide risks via an order in council. This enacted Bill C-30 pesticide override powers mechanism, combined with the proposed changes in Bill C-31, suggests a potential erosion of science-based decision-making in pesticide regulation. The coalition also highlighted that Quebec has formally recognized Parkinson's disease as an occupational illness linked to pesticide exposure since 2021, emphasizing the tangible health impacts at stake.

Bronwyn Roe of Ecojustice stated that the government is moving pesticide laws backward, replacing science-based re-evaluations with a discretionary, opaque process. Lisa Gue of the David Suzuki Foundation warned that scrapping regular reviews could leave outdated risk assessments in place indefinitely, even as new evidence emerges. Over 13,000 Canadians have signed a parliamentary petition advocating for the removal of Bill C-31's pesticide provisions and the repeal of those from Bill C-30, demonstrating significant public concern for Canadian pesticide law reform. Ecojustice and the Association pour la santé publique du Québec presented their arguments to the finance committee on October 8, and the coalition formally submitted a brief urging Members of Parliament to reject the proposed amendments.

Lawyers advising clients in agricultural, chemical, or environmental sectors should monitor the progress of Bill C-31, particularly Section 13, as its proposed amendments could significantly alter federal pesticide oversight, impacting compliance requirements, risk assessments, and potential liability related to pesticide use and environmental protection.
