Jean-Guy Théorêt founded Roxboro in 1972, determined to make his company a success. Roxboro found its home in Montreal's West Island where it is still headquartered today. Faced with the growing needs of his clients and armed with a clear entrepreneurial vision, Jean-Guy quickly expanded his collection of heavy vehicles to make his company more effective.
The 1980s saw an important milestone for Roxboro. Jean-Guy Théorêt's five sons—Yvon, Roger, Raynald, Daniel and Michel—became actively involved in the company, bringing with them determination and know-how just as new technologies and computers were entering their field. During these formative years, Roxboro built a solid reputation in earthmoving, infrastructure and commercial projects. In addition to consolidating its expertise, the company made inroads into new markets and grew its snow removal division.
Committed to diversifying its services, the company also took an interest in sustainability and carried out its first environmental and site restoration projects. In the 1990s, Yvon Théorêt took over running the company from his father, who had seen the number of people in his employ triple since he first founded the business. At this time, Roxboro was working on sewers and watermains, as well for public services such as the Ministère des Transports du Québec.
Since the beginning of the 2000s, Roxboro has seen growth equalled only by the scale of the projects it has worked on. It has intensified and widened the scope of its activities by working on major road and infrastructure projects. In order to gain even more control over quality, Roxboro opened its own asphalt plant in Vaudreuil-Dorion and acquired a mobile plant to service its worksites across Quebec. With some 600 employees during the peak season, the company is now more than ever in a position to meet the expectations of its private and institutional clients. Resolutely forward-looking, Roxboro is synonymous with expertise, efficiency and results.
