About

Founded in 1921 by World War I veterans William R. Black and William "W.J." McDonald, Black & McDonald began as an electrical contractor providing wiring services to residences and small businesses in Toronto. Following the death of his partner in 1946, W.J. McDonald took the company forward and was eventually joined by his two sons John and Bill during the 1950s. By the early 1970s, Black & McDonald had expanded coast-to-coast with a national network of Canadian offices and service offerings that included electrical contracting, mechanical contracting, sheet metal fabrication, HVAC and refrigeration maintenance and repair, and utility contracting. The company's geographic expansion into the United States began in the 1990s with entry into the US utility construction and asset management market in Kansas City. Today, Black & McDonald is owned and led by the third generation of the McDonald family, completing over $2.1 billion in sales annually with more than 6,800 employees operating out of 40+ offices across North America. The company has grown from its humble start as residential electrical wiring contractors to become one of North America's most respected integrated, multi-trade service providers. Black & McDonald is an integrated multi-trade contractor that safely delivers electrical, mechanical, and utility construction and maintenance solutions to clients in the commercial, industrial, institutional, government, and utility sectors. With over 100 years of experience, the company provides comprehensive services including multi-trade construction, integrated facilities management, utilities and renewable energy solutions, and smart infrastructure services. Their facilities management offering incorporates hard and soft services, energy management and sustainability, project delivery, and strategic procurement into one streamlined solution. The company has established itself as Canada's most experienced multi-trade contractor in wind power installation, having completed 23 wind farms ranging from 10MW to 200MW that collectively produce 2,000 megawatts of clean energy. Black & McDonald has also successfully completed electrical installations for 14 solar farms and provides expertise in hydro, battery energy storage systems (BESS), and cogeneration. Black & McDonald remains committed to its founder's Code of Business established by W.J. McDonald, which emphasizes doing the job right, treating employees with respect, building enduring customer relationships, and delivering lasting value. The company's core values include living and working safely, doing it right, always improving, working for one another, building enduring customer relationships, and enabling people to flourish. Excellence in health, safety, and environment is inherent in how Black & McDonald conducts business, with a Health, Safety and Environment Management System based on the ISO 45001 Occupational Health and Safety Management System standard.
