From the people who know how important it is to be able to trust the term “gluten-free”.
The Gluten-Free Certification Program (GFCP) helps consumers identify mainstream products that are safe for people with celiac disease and gluten sensitivity. The program also helps companies manufacturer those products.There are four steps for a company to be part of the system:

There is no such thing as zero risk, but consumers can be confident that products carrying the GFCP logo have been made by manufacturers who have minimized the possibility of gluten contamination.
The Canadian Celiac Association (CCA) developed the standard for GFCP and is the only body that can authorize a company to use the logo. The Allergen Control Group (ACG) administers the program on behalf of the association. ACG staff review the gluten-free management system and auditor reports and make a recommendations to the CCA about certification.
