CGCN Certifications

Quality Vines, Better Grapes

CGCN works to advance the Canadian grape and wine industry by ensuring a sustainable supply of high quality, certified propagative grapevine material. 

CGCN is a collaboration between the Grape Growers of Ontario, the British Columbia Wine Grape Council, l'Association des vignerons du Québec, and the Grape Growers Association of Nova Scotia.

Since our incorporation in 2017, our mandate has been to support research and educational initiatives that promote a clean plant network for domestically certified, virus-tested and pathogen-free grapevines in Canada. 

About CGCN


Our Certification Programs

Through our ongoing research to better understand virus diseases and their impact on grape and wine production, we have developed a national clean plant program to reduce grapevine infections. 

Our Interim Verification Program tests existing propagative blocks to identify infected plants as well as plants at a high risk for infection.

Our Certification Programs work with nurseries to provide domestically-certified, pathogen-free grapevine materials.
