ASCO Construction

What ASCO Construction does

ASCO Construction Ltd. is a privately held Canadian construction company founded in 1988 and headquartered in Hawkesbury, Ontario, with additional regional offices in Ottawa and Toronto/Mississauga. The company delivers projects in the ICI (Institutional, Commercial, Industrial) and Heavy Civil sectors across Eastern Canada, with particular specialization in municipal water and wastewater infrastructure. Its service portfolio includes General Contracting, Construction Management, Design-Build, Project Management, Pre-Construction Services, and Disaster Restoration (the latter delivered through subsidiary ASCO Restoration Services Inc.). Project scale ranges from approximately $50,000 to over $500 million, with notable completed works including the $29.57 million Hawkesbury Wastewater Treatment Plant, the $22.8 million Leslie Street Sewage Pumping Station, and the $8.7 million Cornwall Aquatic Centre. Notable technical and operational credentials include COR safety certification, LEED-certified project delivery, and an Internal Responsibility System for occupational health, safety, and environmental compliance.

The company is family-owned and operated under the Assaly family's leadership, with Anthony Assaly serving as President & CEO since 2001 and Jason Assaly serving as VP Construction for Eastern Ontario & Western Quebec since 1999. Operations are supported by Professional Engineers (P.Eng) and Gold Seal Certified personnel, including District Managers for Central & Western Ontario and Eastern Ontario. ASCO operates under the ASCO Group of Companies umbrella, which includes sister subsidiaries ASCO Restoration Services, ASCO Real Estate, and ASCO Concrete, plus strategic building partners JG Barrette Electric and Dryfab.

ASCO generates revenue through project-based, competitively tendered fixed-price contracts with municipal, institutional, and commercial/industrial clients. Distribution is via direct tender and bid to clients across Eastern Canada, supplemented by a prequalified Building Partner network of subcontractors, suppliers, and design consultants. Customer concentration is heavily weighted toward government and municipal clients, including the City of Ottawa, City of Cornwall, Town of Hawkesbury, and the Regional Municipalities of Durham, York, and Peel. Value engineering, on-time delivery in operational environments (e.g., retrofitting live water treatment plants), and LEED-certified, sustainability-focused construction serve as primary differentiators in a relationship-driven, tender-based market.
