We’re proud to share the impact we made together this March. 💜

Through our partnership with the Cornerstone Family Violence Prevention Centre, Thomas Buick GMC Cobourg donated $20 for every vehicle sold — raising a total of $2,500 in support of their essential work in our community.

Cornerstone continues to be a vital resource for women and children, providing safety, support, and hope when it’s needed most. From emergency shelter to counselling and prevention programs, their work changes lives every single day.

Thank you to everyone who contributed, supported, and helped make this initiative meaningful. Together, we’re making a difference where it truly matters.
