What happens when health or environmental risks are identified for a pesticide that is already registered?
If new scientific information indicates that a registered pesticide may pose unacceptable risks to health or to the environment, then Health Canada may initiate a special review or an early re-evaluation to address concerns. A registration may be withdrawn if the review or re-evaluation finds that the risks are unacceptable. Health Canada closely monitors and reviews scientific findings from around the world on an ongoing basis for current, accurate information for re-evaluating a pesticide, and includes the information in pesticide assessments when it applies.
