Blackthorn was founded 34 years ago in a small garage in Toronto.  From those humble beginnings, the Da Silva family has evolved the business into a specialized niche design-build firm, working on capital projects and programs ranging from $1M to $200M.  

We strive to provide creative solutions that keep the client in the driver’s seat. We are passionate about our clients, our employees, and our projects. We work tirelessly towards our clients’ success - measured economically, socially, and environmentally.
