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 cancellation of a product or product uses. Health Canada may also request changes to a product's label, including mitigation measures, use sites and application methods.

Flucarbazone is an herbicide used on wheat (spring, durum and winter) in Alberta, Manitoba, Saskatchewan, and Peace River region of British Columbia. Highlights of the re-evaluation decision for the active ingredient flucarbazone, published on February 9, 2023, are summarized below.
