Pesticide Transparency and Environmental Protections

Summary#

This is a proposed set of changes to the Pest Control Products Regulations from Health Canada and its Pest Management Regulatory Agency (PMRA). The changes would make it easier for Canadian researchers to inspect certain confidential test data, spell out what must be included in applications for maximum residue limits (MRLs), and give regulators clearer authority to require information about cumulative environmental effects and species at risk. This is a proposal published on June 15, 2024 and comments are being accepted for 70 days after that date.

What it does#

• Confidential test data (CTD)

  • Lets Canadian residents request access to CTD used in PMRA decisions for research or reanalysis without the old affidavit step.
  • Access is limited to data used in a final registration decision or in proposed decisions for post‑market reviews.
  • Requesters must prove identity and residency, explain their research, and agree they will not publish, share, or use the data to register products.
  • Access is time‑limited (up to five years), must be done and stored in Canada, and the original registrant is notified when access is granted.
  • Applicants/registrants will have to flag which of their submitted test data could be CTD so the PMRA can identify it.

• Maximum residue limits (MRLs)

  • Codifies what must be included in an application to set or change an MRL for imported foods or for uses not registered in Canada.
  • Confirms the new public notification process for such MRL applications (already put in place in spring 2024).

• Cumulative effects on the environment (CEE)

  • Gives the Minister explicit authority to require information on cumulative effects for products that share a common mechanism of toxicity, once suitable scientific methods exist.
  • Makes clear that such information must be considered in environmental risk assessments.

• Species at risk (SAR)

  • Gives the Minister explicit authority to require information on effects to species at risk (as defined in the Species at Risk Act) for use in environmental risk assessments.
  • The PMRA would not require additional testing on species at risk.

• Timing

  • The MRL, CEE and SAR parts would come into force on the day the final regulations are published in Canada Gazette, Part II.
  • The CTD rules would come into force 180 days after publication in Canada Gazette, Part II.

Who's affected#

• Researchers, academics, and non‑governmental organizations who want to reanalyse or verify pesticide studies. They must be a resident of Canada to request access.
• Registrants and applicants (pesticide companies and manufacturers) who submit test data to the PMRA. The PMRA estimates about 593 applications/evaluations per year and that roughly 80% of registrants are small businesses.
• Food importers and exporters and anyone involved in setting or complying with MRLs for imported foods.
• Health Canada / Pest Management Regulatory Agency (PMRA) and their partners, including Environment and Climate Change Canada (ECCC), which will be involved on CEE and SAR issues.
• The broader public, because the changes aim to increase transparency about pesticide safety and residues in food.

Why it matters#

• More access for independent researchers could improve public confidence in pesticide safety reviews and may lead to new scientific analysis that the PMRA can consider.
• The CTD access is limited and controlled: requesters cannot publish the confidential data or use it to register products. That aims to balance transparency with protection of trade secrets.
• Clearer MRL application rules and public notifications give consumers and industry earlier notice about requests to allow residues on imported foods.
• The CEE and SAR provisions signal a stronger focus on environmental protection and biodiversity by making it explicit that cumulative risks and species at risk should be considered in PMRA reviews — although regulators say they will only require CEE information once scientific methods are available.
• The proposal would impose small administrative costs on industry (Health Canada estimates an annualized administrative cost of $39,521 under the one‑for‑one rule), mostly for labeling CTD in submissions. The government also noted past investments in the PMRA (for example, $42 million announced in 2021) to support modernization.
• This is a proposal, not final law. Some technical details — especially how cumulative effects will be measured — are still unresolved and will depend on future methods and guidance.
