The Miller Group

What The Miller Group does

The Miller Group, operating through its primary legal entity Miller Paving Limited, is a Canadian construction and infrastructure services company headquartered in Markham, Ontario. Founded in 1917 and acquired by Colas Canada in 2021, the company is a vertically integrated provider of construction materials and infrastructure services spanning the full lifecycle from raw extraction to finished construction and ongoing maintenance. Its core product lines include aggregates from 40+ pits and quarries, hot mix asphalt from 20 Ontario plants, ready mix concrete from 25 fixed plants supported by a 200+ truck fleet, bulk cement, Redi-Rock retaining wall systems, and material transportation. Specialty technical capabilities include an award-winning Cold In-Place Recycling plant capable of 350 tonnes per hour, the Trillium environmental certification across all Ontario asphalt plants, and first-mover status as the only Canadian asphalt producer offering third-party-verified Environmental Product Declarations.

The company generates revenue through three primary motions: competitive bidding on government and P3 infrastructure projects (one-time project revenue), long-term highway maintenance contracts (managed services), and transactional sales of construction materials to contractors and homeowners. Its customer base is concentrated in provincial ministries of transportation and municipal governments across Ontario, New Brunswick, Nova Scotia, Quebec, British Columbia, and Alberta, supplemented by private-sector work. Miller holds 31% of the Ontario highway maintenance market, maintaining 6,962 km of provincial roads under recurring contracts, and has delivered 60+ bridge projects cumulatively valued at approximately $500 million. Over 25 years of P3 experience positions it as equity partner, constructor, and operator on major alternate project delivery engagements.

The Miller Group operates through a network of regional subsidiary brands — including Brennan Paving, Lavis Contracting, Georgian Paving, MacDonald Paving, Miller Capilano, Entretien Miller, Miller Maintenance, and others — each retained for local market credibility. The firm maintains COR safety certifications in four provinces plus Saskatchewan equivalency, an SBTi-validated 30% carbon reduction commitment, and active memberships in ORBA, OGRA, OSSGA, OGHPA, and Concrete Ontario. Recent strategic activity includes the March 2024 acquisition of three ready-mix businesses (Muskoka, Parry Sound, Champlain) and the May 2026 acquisition of Summit Aggregates KW Inc., signaling a programmatic tuck-in M&A strategy focused on regional materials supply density.
