What M. Sullivan & Son does
M. Sullivan & Son Limited is a privately held, family-owned general contractor founded in 1914 in Arnprior, Ontario, specializing in bespoke Industrial, Commercial, and Institutional (ICI) construction across Eastern and Northern Ontario and Quebec. The firm operates three offices (Arnprior HQ, Kingston regional HQ, North Bay regional office) and delivers projects through four core models: General Contracting, Construction Management, Design-Build, and Integrated Project Delivery (IPD), with selective use of Engineer-Procure-Construct (EPC) on complex clean-energy work such as the Ontario Power Generation Calabogie Generating Station redevelopment.
The company's project portfolio spans healthcare (Kingston Health Sciences Centre, North Bay Regional Health Centre), post-secondary education (Queen's, Carleton, Laurentian), national defence (CFB Petawawa, CFB Bagotville), clean energy and nuclear (OPG Calabogie, CNL New Builds — the largest IPD project in Canadian history at inception), municipal infrastructure (Kingston East Community Centre), and heavy civil work executed in-house. Notable technical differentiators include mass timber construction on federal projects, LEED-certified delivery (Silver, Gold, and Platinum outcomes), an in-house heavy civil site work unit, and adoption of lean continuous improvement across project lifecycles. Strategic joint ventures — Iroquois-Sullivan (51% Indigenous-owned), Sullivan-Chandos, and SNC Lavalin & Sullivan — extend capacity on marquee projects.
Revenue is generated through project-based contracts priced via competitive bidding and direct negotiation, with multi-year contract cadence and quote-based engagement rather than recurring subscription or licensing models. Sullivan is credentialed across ISO 9001, 14001, and 45001, COR, multiple LEED levels, Progressive Aboriginal Relations (PAR) Phase 1, and has maintained Deloitte Best Managed Companies Platinum status for over ten consecutive years. Leadership includes Rob Ball (President and CEO), Matthew Purdy (CFO), and P. Gregory Sullivan (Sr. Vice President, General Manager Kingston), with the founding family still represented in senior ranks.
