J-AAR

What J-AAR does

J-AAR is a vertically integrated civil construction and materials company headquartered in London, Ontario, serving Southwestern Ontario. Founded in 1978 and incorporated in 1982, the company operates through three divisions: the Civil Infrastructure Group (excavating, site works, public works, paving, utilities, stormwater management), the Structural Group (concrete forming for ICI/residential and mid/high-rise projects), and the Materials Group (aggregates, asphalt, ready-mix concrete via the Dutch Brothers partnership, sand, soil, mulch, and C&D recycling). It owns an extensive fleet of heavy construction equipment, ten aggregate pit locations across the region, and an in-house asphalt plant commissioned in May 2025.

The business serves a mix of municipal and private-sector clients. Government and municipal customers include the City of London, the Region of Waterloo, and Hydro One; private customers include residential developers (Mattamy Homes, Old Oak Properties, HLH Investments), industrial and institutional clients (Maple Leaf Foods, Hamilton Health Sciences, Skyreach Group), and project partners on joint pursuits (EllisDon, Graham, McLean Taylor). Marquee projects include London's tallest building between Mississauga and Calgary (40-storey Centro tower), a 100-acre Maple Leaf Foods plant, the 200+ lot Wildflower Subdivision in Kitchener, and the Adelaide Underpass with 40,000m3 of excavation. Distribution is project-based via direct bidding and contracts, with materials also sold over the counter from pit locations.

J-AAR is a private, family-owned company controlled by the three Aarts brothers (Ryan as CEO, Kevin as CAO, Jonathan heading Orange Rock Developments). It has grown both organically and through serial acquisitions — Concrete Forming 1980 and N.J. Spivak (2019), Walmsley Bros. Paving (2020), a Cambridge office (2022), and the Seegmiller Group's heavy civil division (October 2025) — and today operates with 580+ team members. Revenue is not publicly disclosed. The company competes on vertical integration, owned aggregate reserves, regional reputation, and family-controlled continuity rather than on technology differentiation.
