Building with Integrity, Driven by Purpose

We’re not just constructing buildings. We’re building opportunity, impact, and a better future — together.

At McDonald Brothers Construction (MBC), we believe in building more than structures – we build stronger, more connected communities. As a partner, we create spaces that truly serve their users, nurture vibrant communities, and stand resilient for generations.

With a foundation of professionalism, unwavering safety, and technical excellence, we deliver complex, large-scale projects across the greater Ottawa area and beyond.

From schools where children learn, recreation centres where communities gather, hospitals that heal, to public infrastructure that connects us all — MBC brings decades of experience guided by a values-first approach. This means embracing diverse and inclusive hiring, sustainable building practices, and community-first procurement in every aspect of our work.
