Established in 1983 by the Chouinard family, Superior Grading (SG) specializes in commercial, industrial, and mining projects in Northern Ontario. Initially focused on premier grading and clearing services for construction, mining, and forestry, SG expanded in 1999, investing in excavators, bulldozers, dump trucks, and loaders to enhance their earthworks division.
With 37 years of quality service, SG has become the trusted name for road construction, road maintenance, snow removal, and earthworks projects. The 2014 acquisition of G.R. Roy Construction further broadened our capabilities by adding residential, commercial, and industrial expertise.
With a team of versatile and experienced professionals, SG and G.R. Roy is equipped to handle projects ranging from simple to complex. We maintain our reputation as the “go-to” contractor in the North, consistently delivering projects on time and within budget.
