With a history spanning over a century, the company has established a strong presence across North America, built on a foundation of delivering customer-focused solutions and operational excellence. Founded in 1921 by William John (W.J.) McDonald and William R. Black, the company began as an electrical wiring contractor in Toronto, primarily serving residential customers. Over the decades, Black & McDonald expanded its services and geographical reach. By the early 1970s, it had become a coast-to-coast Canadian company offering electrical and mechanical contracting, sheet metal fabrication, HVAC and refrigeration services, and utility contracting. The company's growth continued with its entry into the United States market in the 1990s, focusing on utility construction and asset management.

Today, Black & McDonald remains a family-owned and operated business, currently led by the third generation of the McDonald family. The company emphasizes its core philosophy of 'Do things right' and 'Deliver lasting value,' which has guided its operations since its inception. Its comprehensive service offerings cover the full project and asset lifecycle, from engineering and design, fabrication and modular construction, to multi-trade construction, facility services, utility services and renewables, energy and sustainability services, and nuclear services.
