Black And McDonald

From our humble start in 1921 as an electrical wiring contractor, Black & McDonald (@blackandmcdonald) has grown to multiple lines of business with more than 5,000 employees working out of 30+ offices, and become one of North America’s most respected integrated, multi-trade service providers.

Today, we remain a family-owned and operated business driven by our founder’s philosophy to “Do things right” and “Deliver lasting value”. That simple promise remains at the core of everything we do.
