What started as a spark—a desire to set a new standard for infrastructure delivery—has grown into a $50B legacy of impact across Canada.
For 25 years, our teams have partnered with ambitious clients, helping them navigate uncertainty, manage complexity, and bring visionary projects to life—modernizing national landmarks, building resilient communities, and empowering growth. This anniversary isn’t just a celebration of where we’ve been. It’s a bold step toward where we’re going.
As Tiree marks 25 years of delivering impact, I am extremely proud of our talented team, whose skill, commitment, and vision have shaped our success. Every project we undertake reflects their dedication—and the ambition of our clients that we are privileged to support. Looking ahead, we remain committed to building on our legacy: delivering excellence, embracing innovation, and helping our partners realize the projects that will define the future." - Mark LeBlanc, President
