All pesticides used in Canada must be registered under the Pest Control Products Act. Pesticides are re-evaluated to ensure that they continue to meet health and environmental requirements. Re-evaluation may result in the revocation of a product or product uses. Health Canada may also request changes to a product's label, including risk mitigation measures, use sites and application methods.

Cyfluthrin is a synthetic pyrethroid insecticide used by pest control applicators against flying and crawling insects, by farmers on livestock housing structures and by the cattle industry. Domestic products are for indoor use against household pests such as ants, earwigs, cockroaches and spiders. Highlights of the re-evaluation decision of the active ingredient cyfluthrin (non-agricultural uses), published on October 31, 2018, are summarized below.
