Who We Are


Graham Bros. is one of Ontario‚Äôs largest independent, full-service, heavy-equipment construction contractors. We employ a skilled and versatile staff of 400 people. We own a multi-faceted fleet of world-class equipment and control our supply of raw materials.

Given the strategic location of our head office and production facilities, we have developed an understanding of the requirements of communities within the Southwestern region of Ontario and have become particularly proficient in procuring work in these areas. However, Graham Bros. is capable of servicing areas throughout Ontario. 

Our objective is to build relationships with our clients in order to better understand their needs and equip us with the knowledge necessary to provide superior service. 

BUILT WITH PRIDE is more than a slogan. It is our mission. We put quality first to create the solid infrastructure that paves the way for progress.
