What Our Clients Say

Over the past fourteen years, T. Harris Environmental Inc. has worked with PCL on three large asbestos abatement projects within the Ottawa area. These landmark projects include the Victoria Memorial Museum Building Rehabilitation project, the Saint Vincent Hospital Renovations and Addition project and currently, the West Block Rehabilitation Project. Given the complexities and challenges of these projects, their knowledge, practicality and quick response to issues has been an asset for the owners, consultants and contractors.”

– Irvin Heiber, PCL Constructors Canada Inc.

I wanted to thank T.Harris for your fantastic customer service, prompt response, availability to meet my needs and follow-up. Your team was very professional, knowledgeable and friendly. The onsite technician answered all my questions and even provided me with additional resources to potential issues outside of the test they were conducting. I will definitely recommend T.Harris for any of your services to friends and clients.

– Amanda Williams, Homeowner

We are a high-end residential contractor company and ESA provided a list of qualified companies that could provide testing and a report re possible asbestos on the property we had renovated. We contacted T. Harris Environmental Management Inc. who were very professional in explaining the process, provided a quote and were able to conduct the testing and deliver a report in less than 24 hours. The service we received was exemplary. We would highly recommend the services of T. Harris Environmental Management Inc. and we will definitely contact them in the future.

– David E. Strathy, Montclair Construction Limited
