Building Toronto’s Future—One Project at a Time

From transformative infrastructure to advanced industrial facilities and world-class commercial developments, Graham is invested in shaping the skyline, streets, and communities of the Greater Toronto Area.

We are proud to have played a role in some of the region’s most significant undertakings. The Davenport Diamond Rail Grade Separation, one of the largest transit infrastructure projects in Toronto, improves efficiency and safety across one of the busiest rail corridors in North America. On the water and utilities front, our work at the Ashbridges Bay Treatment Plant and the Cherry Street Stormwater Management Facility supports essential environmental protection and resiliency for Toronto’s growing population.

Graham is also contributing to the future of commerce and logistics, with major facilities such as Amazon Delivery Stations and a Costco Distribution Centre, strengthening supply chains and supporting regional economic growth. In the education sector, we’re delivering spaces that balance heritage with innovation. At Queen’s University, we’ve restored and modernized historic residences to serve new generations of students, while in Toronto, the under-construction Lawson Centre for Sustainability at Trinity College, University of Toronto showcases our expertise in mass timber and sustainable design.

As one of North America’s leading construction solutions providers, Graham combines local expertise with national resources and a strong record of collaboration. Our Toronto team is trusted to deliver across the region’s most vital sectors—including transportation, water, healthcare, education, and mixed-use development. Guided by our core values of Commitment, Integrity, and Reliability, every project is built to endure.
