The Tomlinson Group of Companies is a Canadian construction firm based in Nepean, Ontario, with operations spanning construction, aggregates, asphalt, concrete and environmental services. Founded in 1952, it began with a single-axle dump truck and evolved into a multidisciplinary organization capable of managing large civil, municipal and commercial infrastructure projects. It offers end-to-end site development—from excavation to asphalt—with LEED-certified material management and a focus on durable, high-quality outcomes. Its client base includes public and private sector clients seeking integrated infrastructure solutions across services such as road, bridge, water and sewer work, environmental remediation and waste management. In 2026, the group expanded its Ottawa-area offices and opened a presence in Tweed, Ontario, and acquired Barron Disposal Systems Inc. to broaden its environmental services footprint in Eastern Ontario.
