Transforming
cities across
North America
since 1975.

WE'VE COME A LONG WAYGreat Gulf began in 1975 with a mission to transform.

From our first lot in Cambridge, Ontario, to residential, commercial, and recreational developments in 18 cities across North America, we’ve come a long way. While a lot has changed in that time, one thing has not: our unwavering commitment to building great spaces that inspire the people who live, work, and play there. With over 45 years of experience, we continue to transform and lead the industry with technology, sustainable design, and innovation with a multi-faceted portfolio including commercial, mixed-use & residential development, construction management & software, panelization manufacturing, architecture, and hospitality.

The Great Gulf Group of Companies was built on the principles of integrity and trust. With an entrepreneurial spirit and a commitment to the pursuit of excellence, our mission is to preserve and enhance the value of the capital entrusted to us by our customers, equity partners, founders, and other stakeholders. At Great Gulf, we are committed to delivering diverse and robust strategic community transformations through innovative design, intelligent construction, and dedicated devotion to the well-being of our customers.
