The ARHCA is the largest heavy construction association in Canada. We represent contractors who work on the construction and rehabilitation of highways, municipal roads, bridges, sewer, and water projects, as well as the suppliers (such as equipment dealers, finance companies, aggregate suppliers, law firms, etc.), and consulting engineers who work with them. ARHCA member companies can also be found constructing streets, curbs and gutters, sewer and water systems, and other infrastructure for residential, commercial, oilfield, oil sands and forestry projects.
