The certification program is open to companies involved in production, handling and brokerage of fresh fruits and vegetables who need to demonstrate to their customers that they are implementing food safety programs and/or following the CanadaGAP manuals. Buyers may be asking specifically for CanadaGAP certification, in which case operations should enrol. If an operation is not sure exactly what is required, they should contact their customer(s). A number of buyers have endorsed the CanadaGAP Program (along with other food safety programs that are recognized by GFSI), such as Metro, Loblaw Companies Limited, Wal-mart, McCain Foods Canada, Simplot Canada, Lamb-Weston, Cavendish, etc.).
