How often does Health Canada review registered pesticides for continued safety and efficacy?

Health Canada conducts a review of registered pesticides for continued safety and efficacy every five years. This regular review process is crucial to ensure that the pesticides in use do not pose unacceptable risks to human health or the environment. It provides an opportunity to assess new data that may have emerged since the initial registration or previous reviews, including scientific studies, adverse incident reports, and changes in usage patterns. This systematic approach helps to maintain the integrity of pesticide regulations and ensures that only safe and effective products remain available on the market. Regular reassessment every five years also aligns with best practices in regulatory science to adapt to evolving knowledge about pesticide effects and safety standards.
