About Us


Marine Contractors - Incorporated in 1923, The Ontario Construction Company Limited operates today as a third generation marine and heavy construction contractor. The company's first contract, in 1923, was to construct a section of the Welland Ship Canal at St. Catharines. We are the only canal contractor from that era still continuing in operation today. Our marine and heavy construction contracting business has been in operation for almost 100 years. As marine and heavy construction contractors, we work throughout Ontario for a diverse clientele, sometimes in a variety of remote locations and under assorted, unusual working conditions. Our crews, all consisting of long term employees, are well experienced with our marine and heavy construction specialties. We maintain a modern, specialized equipment fleet of heavy duty construction and marine plant which complements our construction specialties. All of our equipment including marine plant is fully road transportable.
