Aggregate Operation Locations in Ontario

Our aggregate operation locations in Ontario are places where CBM has built long‑standing relationships with contractors, engineers, and municipalities that depend on a consistent supply. Because our teams live and work in these communities, we understand local conditions, common project types, and typical timelines, which allows us to anticipate needs, tailor advice, and respond quickly when plans change. Our local presence also means we know the roads, access points, and site constraints in each area, so we can coordinate deliveries with minimal disruption and maximum efficiency.
We are a local partner who gives you the certainty you need to stay on schedule. Whether you are sourcing for a large-scale highway project or a local commercial development, our CBM aggregate teams are ready to provide the exact materials you need, right when you need them.

A Supply Chain Built on Reliability

Running multiple quarries, pits, and depots across the province means our customers are never dependent on a single source. When demand shifts or volumes increase at one location, others are ready to step in seamlessly. This depth of coverage translates to more predictable supply, fewer delays, and an ordering process that gives teams the confidence to plan ahead without constant follow-up.
• Smarter Proximity: We have positioned our sites to reduce haul distances, which keeps your costs down and helps us lower our carbon footprint on Ontario’s roads.


• Scalable Volume: With a massive inventory across our pits and quarries, we have the bench strength to handle sudden surges in demand without breaking your stride.


• Transparent Communication: Our logistics teams work as an extension of your crew. We use our integrated network to provide real-time updates and firm delivery windows, taking the guesswork out of site management.CBM produces EPDs for our ready-mix concrete products. If you need EPD documentation for a specific mix design or project submission, a CBM representative can provide the relevant materials and confirm product coverage.

Rooted in the Regions We Serve

Our stone, sand, and gravel locations across Ontario are places where CBM has built long-standing relationships with the contractors, engineers, and municipalities that depend on a consistent supply. Our teams are local, and that familiarity shapes how we communicate, coordinate, and follow through.
We also take our role as a neighbour seriously – maintaining Open Dialogue with surrounding communities, managing our sites responsibly, and progressively rehabilitating the land we use back to farmland and naturalized areas.

High-Performance Standards at Every Quarry

  • Aggregates impact the quality of what is built with them. At every one of our aggregate operation locations in Ontario, dedicated quality control staff conduct regular testing to confirm products meet applicable specifications before they leave the site. Our range covers base materials for roadways and runways, structural fill, rip rap, raw materials for ready-mixed concrete and asphalt, water filtration applications, and agricultural lime.
  • Standardized Quality: Whether you’re picking up from a site in the GTA or a quarry in Eastern Ontario, our production standards ensure you’re getting the same durable, high-spec material every time.

  • Consultative Solutions: Need a custom gradation or help meeting a specific environmental standard? Our local experts are ready to collaborate on-site to ensure your project hits every safety and performance target.
