Colas wins major multi-year road maintenance contract in Canada

Colas, through its Canadian subsidiary The Miller Group, has been selected by the Ministry of Transportation of the Province of Ontario to carry out all maintenance work on the road network in the Durham region, east of Toronto, in the province of Ontario.

This major contract, worth around 100 million euros[1], covers a period of seven years, starting in August 2026.

Under this contract, more than 40 employees will be mobilized full-time all year round, a team reinforced each winter by 160 specialized equipment operators.

During the summer, The Miller Group will be responsible for roadway repairs, shoulder maintenance, guardrails, drainage structures and systems, as well as vegetation and electrical equipment management. In the winter, the teams will carry out snow removal operations, sand and salt spreading, and preventative and curative snow and ice treatment to ensure user safety in all circumstances.

In line with its commitments to environmental protection, the subsidiary will implement several concrete actions to limit the carbon footprint of its operations. Two low-emission patrol trucks will be deployed at the project's launch, with the goal of gradually expanding this fleet. The idling management program will be strengthened with tracking software that analyzes and optimizes vehicle behavior in real time.

In addition, all emergency response units will be equipped with dual batteries. Finally, all hand tools will also be battery-powered, thus reducing emissions.

"This contract demonstrates the Ontario Ministry of Transportation's confidence in The Miller Group. We are proud to maintain this strategic network, combining operational performance, innovation, and environmental protection, all while ensuring user safety," said Francois Vachon, Colas' Managing Director, Canada.

Established in Canada for nearly 60 years, Colas is strengthening its commitment to providing high-quality road maintenance services with the signing of this new contract, which is fully in line with its sustainable regional development strategy. Regular road network maintenance improves user safety and avoids the additional costs associated with complete infrastructure repairs.
