What Dufferin Construction does

Dufferin Construction Company is a Canadian heavy civil construction contractor founded in 1912 by James F. Franchescini and headquartered in Oakville, Ontario. Operated as a division of CRH Canada Group Inc. - itself a subsidiary of Ireland-based CRH plc - the firm delivers roadways, bridges, interchanges, tunnels, airport infrastructure, marine structures, rail and transit infrastructure, municipal infrastructure, and site development services. Primary clients are provincial transportation ministries (Ministry of Transportation Ontario, Infrastructure Ontario, Ministère des Transports du Québec), transit authorities (Metrolinx), airport authorities (Greater Toronto Airport Authority, Calgary Airport Authority), municipal governments (Regions of York & Peel, City of St. Thomas), and utilities (Ontario Power Generation, St. Lawrence Seaway Management Corporation).

The company's capabilities combine heavy civil construction with vertically integrated materials supply. Dufferin operates seven strategically located hot-mix asphalt batch plants across Southern Ontario, sources aggregates, ready-mix concrete, and additional asphalt through sister operating units (Dufferin Aggregates, Dufferin Concrete, Dufferin Asphalt), and holds the proprietary patented Dufferin SlipStone Extruded Wall System for textured slip-formed walls. It also operates aggregate recycling facilities processing hundreds of thousands of tonnes of concrete and asphalt rubble annually into MTO-approved road base granulars, mobile concrete and asphalt plants enabling on-site production, and the 50/50 Yellowline Asphalt Products joint venture with Aecon Construction & Materials Ltd. for MTO-approved asphalt cement manufacturing. In 2017 Dufferin acquired K.J. Beamish Construction Co. Limited, expanding its Ontario operating footprint.

Revenue is generated through two principal mechanisms: (1) project-based heavy civil construction under competitive bid, with multi-year contracts executed under General Contracting/Bid-Build, CM/GC, Design-Build, Design-Bid-Build, and P3/Public-Private Partnership delivery models; and (2) transaction-based materials sales through the asphalt plant network and aggregate yards at quote-based pricing tied to volume, mix specification, and delivery location, supported by a dedicated sales line (tel:+19058427974). Geographic operations centre on Ontario, with project-based activity in Western Canada (e.g., Calgary Airport, Edmonton International Airport), Quebec (via Demix Construction, Demix Agrégats, Demix Béton), and Nova Scotia.
