Lean Construction Services believes construction works best when teams are aligned, planning is disciplined, and processes are intentional. Our lean construction approach focuses on collaboration, efficiency, and predictable project delivery.

Founded as Ross & Anglin Ontario, we have always operated as a family-owned construction company committed to doing things the right way. In April 2021, we rebranded to Lean Construction Services to reflect our forward-thinking vision — bringing together owners, engineers, OEMs, subcontractors, and trades to deliver smarter, safer, and more efficient construction outcomes.

Here’s what truly sets us apart: we don’t sit across the table from our clients — we sit beside them. We believe in full transparency. No games. No hidden agendas. No surprises.



At our core, we remain a family business built on trust, guided by integrity, and focused on delivering long-term value across every commercial and industrial project we build.
