Health Canada has completed the re-evaluation of imidacloprid. Under the authority of the Pest Control Products Act, Health Canada has determined that continued registration of most products containing imidacloprid is acceptable. An evaluation of available scientific information found that most uses of imidacloprid products meet current standards for protection of human health and the environment and have acceptable value when used according to revised conditions of registration, which includes new mitigation measures. However, certain uses of imidacloprid are cancelled to address potential risks of concern to the environment. Cancelled uses are listed in the Risk mitigation measures Section below. Label amendments, as summarized below and listed in Appendix XI of RVD2021-05, are required.
