As we celebrate Manufacturing Month, we're recognizing the people whose skill, dedication, and commitment help keep our operations moving every day.

Meet Marina Duke, Roll Form Operator at CGC Oakville. 👷‍♀️

With 4 years at CGC, Marina plays an important role in helping keep production running safely and efficiently. What she values most about manufacturing is that while there’s a daily routine, no two days are exactly the same. Each day brings new challenges, opportunities to learn, and chances to improve.

For Marina, CGC stands out because of its strong safety culture. While quality is essential, safety always comes first. That commitment helps our teams continue producing the high-quality building products that support Canada's homes, schools, hospitals, and communities.

Marina's experience reflects what makes manufacturing so rewarding: continuous learning, teamwork, and a shared focus on doing the job safely and well.

From Quebec to Ontario, building Canada starts close to home. 🍁 🏗️

We recently welcomed five architects from Quebec to Ontario for tours of CGC Hagersville and CGC Oakville, where they saw firsthand how the materials and solutions they specify are made.

From gypsum to specialty ceilings, the tour offered a closer look at the people, processes and expertise behind products made right here in Canada.

Du Québec à l’Ontario, bâtir le Canada commence tout près de chez soi. 🍁 🏗️

Nous avons récemment accueilli cinq architectes du Québec pour une visite des installations de CGC à Hagersville et à Oakville, leur permettant de découvrir concrètement la fabrication des matériaux et des solutions de produits qu’ils spécifient.

Des panneaux de gypse aux plafonds spécialisés, cette visite a offert un aperçu privilégié des personnes, des procédés et du savoir-faire qui se cachent derrière des produits fabriqués ici même, au Canada.
