For over a 100 years, we've built a solid reputation for completing quality projects on time and on budget.
M. Sullivan & Son Limited is one of Canada’s oldest family-owned construction companies. Founded in 1914, we are in our 105th year of operation as a full service general contracting firm. For over 100 years our continuous service is clear evidence of our dedication to quality and our financial and corporate stability.
Our reputation for completing quality projects on time and on budget, consistently meeting or exceeding expectations for quality and safety, has led to our ongoing recognition as a Platinum member of Canada’s Best Managed Companies – a designation we pledge to maintain our strategy, capability, commitment and financials to our employees and to our clients.
I learned many things on this project but the first lesson I learned from Sullivan's site supervisor was the difference between cement and concrete and I will never make that mistake again.
At M. Sullivan & Son Limited, high quality is not a vague promise. This goal is achieved through a quality management system (QMS) that meets the strict requirements of the ISO 9001:2015 standard which we have complied with since 2009.
M. Sullivan & Son Limited has thrived for over a century partly because we honour not only the traditions of our craft but also the innovations that serve to strengthen those traditions over time.
In fulfilling our mission, M. Sullivan & Son Limited will strive at all times to provide its goods and services in a way that respects the dignity and independence of people, including people with disabilities.
M. Sullivan & Son’s head office is located in Arnprior, Ontario with an office in Kingston, Ontario since 1949. We are also located in Ottawa and North Bay, Ontario.
