North American Construction Group (NACG) is Canada's largest independent heavy equipment and mining contractor, delivering large-scale earthworks, mining and energy contracting services. The company traces its origins to 1953, when brothers Ivan and Bob Gouin founded it as a family business with a single secondhand bulldozer. Its operations span Canada, the United States and Australia, with particular concentration in Alberta, British Columbia and the oil sands region around Fort McMurray.
NACG's work falls into several distinct service lines. Heavy civil construction covers large-scale earthworks and infrastructure projects, with roots in road building across Alberta and British Columbia. Mining operations involve mining, developing and reclaiming land for oil sands and energy sector clients. The company also carries out equipment maintenance and refurbishment for heavy mining and construction machinery, sources OEM parts for equipment fleets, and undertakes land reclamation. Its industries include mining, oil sands, energy, construction and infrastructure.
With more than 70 years of experience, NACG operates one of the largest independently owned fleets of haul trucks, shovels and mining equipment in North America. The company reports millions of hours worked without a lost-time incident in Alberta's oil sands. Its stated commitments include sustainability, Indigenous partnerships and maintaining its safety record.
