What Brock Aggregates does

Brock Aggregates Inc. is a privately held Canadian industrial firm that extracts, processes, and distributes construction aggregates — primarily sand, stone, gravel, limestone, and limestone screenings — from company-owned pits and depots across Southern Ontario. Founded in 1997 and headquartered in Concord, Ontario, the company operates as a subsidiary of the Juel Group (formerly G&L Group) alongside affiliated brands Earthco Soil Mixtures, Draglam Waste & Recycling, and Toronto Redi-Mix Concrete. Production capacity is approximately 750,000 metric tonnes per year, drawn from five to seven owned gravel pits (Whitby, Sunderland, Tottenham, Stouffville, Orangeville, and others depending on source period) and a network of depots spanning Concord, Etobicoke, Bradford, King City, Stouffville, Whitby, and Delta Park. The Sunderland Pit also features a distinctive underwater mining operation using an 800 series link belt excavator on a barge with a 6-yard clamshell bucket, de-watering screen, and floating conveyor system. All products are tested to meet Ontario Provincial Standard Specification (OPSS) standards.

The company's product portfolio spans limestone products (3/4 and 2" crusher run, clear limestone, HL6, screenings, HPB), gravel products (Granular A and B, HL6 gravel, 3/8" pea gravel), sand products (sand fill, concrete sand, brick sand, cable sand, winter sand), stone products (concrete stone, gabion stone, river stone, specialty decorative stone), and rocks (rip rap). Supporting offerings include a web-based Aggregate Volume Calculator, Flexible Intermediate Bulk Container (FIBC) bulk-bag packaging, and a multi-vehicle delivery fleet (Dump Truck, End Dump, Stone Slingers, Blower Trucks, Tele-Belt, Trailers) operating six days a week from a central dispatch in Concord.

Brock Aggregates operates a sales-led go-to-market motion with quote-based pricing, accepting orders via phone (416.798.7050 / 1.800.870.0926), email, and online. Revenue is generated through one-time aggregate material sales (priced per unit with delivery charges based on quantity) to construction companies, contractors, developers, landscapers, and municipal/government clients throughout the Greater Toronto Area and Southern Ontario. Customers can either arrange bulk fleet delivery to job sites or self-pick up at multiple depot locations. The company markets through content (blog "The Fill"), organic social (Twitter/X, LinkedIn, YouTube, Instagram), an email newsletter ("Brock Talk" via Constant Contact), SEO, and participation in the Ontario Stone, Sand & Gravel Association (OSSGA).

Direct peers

• Walker Industries: Ontario-based family-owned diversified materials company operating aggregate pits, asphalt, recycling and construction services across Southern Ontario. Closely comparable mid-sized Ontario aggregate peer with overlapping product range and GTA distribution footprint.
• Dufferin Aggregates (CRH): A major Ontario aggregate producer owned by CRH plc, operating multiple pits and quarries across the Greater Toronto Area and Southern Ontario. Direct competitor in the same OPSS-spec sand, gravel and stone markets with overlapping customer base of GTA contractors and municipalities.

Broad incumbents

• Lafarge Canada (Holcim): A large Canadian subsidiary of Holcim Group supplying aggregates, cement and ready-mix concrete across Ontario. Competes with Brock on aggregate supply and concrete raw materials while offering a much broader product portfolio including cement manufacturing.
• Martin Marietta Materials: One of the largest U.S. aggregate producers operating crushed stone, sand and gravel quarries. Comparable in aggregate-product focus and OPSS-equivalent spec-driven business model, though primarily U.S. geography.
• St. Marys Cement (Votorantim Cimentos): Major Canadian cement and aggregate producer operating quarries across Ontario, owned by Votorantim Cimentos. Supplies similar limestone-based aggregates and competes for the same infrastructure and concrete-mix customers as Brock.
• Vulcan Materials Company: Largest U.S. producer of construction aggregates — crushed stone, sand and gravel. Closely comparable commodity aggregate business model with a quarrying-led operating model; serves as a useful reference for unit economics, even though its footprint is U.S.-only.

Regional players

• Nelson Aggregate Co. Family-owned aggregate producer operating in Simcoe County and surrounding central Ontario regions. Comparable regional peer producing sand, gravel and stone for construction, though more geographically focused outside the immediate GTA core.
• Tomlinson Group: Eastern Ontario-based construction materials and environmental services firm producing aggregates and supplying ready-mix concrete. Comparable vertically integrated peer though its primary footprint is Ottawa-area rather than GTA.
