On the job
For over 3 decades.
It all started with grading
Established in 1983 by the Chouinard family, Superior Grading (SG) specializes in commercial, industrial and mining projects. Based in Northern Ontario, SG's roots began with providing a variety of premier grading and clearing services for the construction, mining and forest industries. In 1999, SG expanded their scope of work by investing in excavators, bulldozers, dump trucks and loaders to expand their earth works division.
With 37 years of quality service, Superior Grading has become the name people trust for all their road construction, road maintenance, snow removal and earth works projects.
In 2014, the acquisition of G.R. Roy Construction enabled the scope of our work to expand again. Residential, commercial and industrial, G.R. Roy's portfolio is vast. From foundations (concrete) to trusses, G.R. Roy has done A to Z in a quality and time-effective manner. Based in Timmins, Ontario, G.R. Roy established itself as a leader in building high quality industrial buildings in the North
With a team of versatile and experienced employees, SG/G.R. Roy can competently and professionally take on projects from simple to complex. We continue to live up to our reputation as the "go-to" contractor in the North, delivering on-time and on-budget.
