Who We Are

Five generations of success.

What started in 1887 as a modest, single cut stone quarry has evolved into today’s multi-divisional diversified enterprise with over 1200 employees across North America.

Walker is the product of strong family heritage, driven by the rich and diverse history of the businesses it has developed, grown and acquired over the past century. Passed down through five generations of the Walker family, we remain committed to doing the right thing for employees, customers, the environment and the communities we are proud to call home. That is the Walker way.
