About One Horizon
The principals and associates of Horizon General Contractors have been involved with all aspects of construction from specialized mechanical and electrical work, renovation, restoration, and addition, to free-standing new construction projects for the private and public sectors since 1972.
Our goal is simple: to build prosperity with you. What we build is about more than what we construct. It starts by listening, learning, and seeking to truly understand our clients. We believe the best outcomes come from partnership, not transactions. Together, we will go hard on the task, while bringing empathy, understanding, and alignment to our shared success.
Philosophy Rooted in Heritage and Built Through Generations
Our team brings a wealth of experience in delivering projects that generate meaningful social and economic impact. Foundational pillars of our company ethos: restoration, resilience, and service to the community.
Tradition in Practice
Since 1972, our work has carried forward the principles of craftsmanship, integrity, and respect for structure that define Toronto’s architectural heritage.
Private and Public Sectors
From municipal projects to private developments, our record reflects decades of trusted collaboration built on transparency and professional conduct.
Preservation with Purpose
We approach restoration and renewal as a responsibility—to protect the character of what was built before while creating spaces that serve the present.
Building Communities
with Purpose
Building with Purpose means building for collective prosperity. It is the idea at the heart of every project we undertake. From our early days in the heart of Toronto to larger developments across Ontario, our work has been guided by care, responsibility, and the belief that what we build should serve communities for generations to come.
