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 mitigation measures, use sites and application methods.

Ethephon is a plant growth regulator. It accelerates fruit ripening/maturity and plant growth and development through the release of ethylene gas, a natural plant hormone. The highlights of the re-evaluation decision for the active ingredient ethephon, published on September 24, 2020, are summarized below.
