Exceeding Client Expectations

“Dunford-Liscio (Ontario) Inc. (DLO) has successfully completed several base building air handling unit and laboratory fumehood exhaust systems at University of Toronto, Mississauga campus in the last few years. These projects were delivered on time and on budget and the operational results are outstanding, along with being esthetically pleasing. I have been involved with many large and small scale projects with DLO and find them well organized, professional and hold a high level of integrity. I would not hesitate to recommend them for projects in any building in high education environment.”
