North American Construction Group Ltd. operates through two primary divisions: Heavy Construction & Mining and Equipment Maintenance Services. The company's core services include contract mining, overburden removal, site preparation, reclamation, and the provision of fully maintained heavy equipment rentals. Geographically, the company has significantly expanded its footprint beyond its historical base in the Canadian oil sands, with Australian operations now accounting for the majority of its revenue following strategic acquisitions such as the MacKellar Group. Its equipment maintenance segment provides fuel and lube servicing, major overhauls, and component remanufacturing to support both its own fleet of over 600 units and external clients. By diversifying across multiple commodities—including iron ore, metallurgical coal, and gold—the company mitigates regional cyclicality while maintaining a strong position as a premier on-site mining contractor.
