It is with great pleasure that John C. Fisher, on behalf of all employees of T. Harris Environmental Management Inc. (THEM), announces our 35th Anniversary and shares the history of our humble beginning. It was a cold day in the winter of 1979 when Trevor Harris got into his little blue Honda Civic, which would later bear the license plate “BESTOS”, and opened the first consultancy in Canada dedicated to solving problems associated with asbestos-containing materials (ACM).  Trevor not only proved to be a pioneer in the management of asbestos-containing materials but as a matter of fact, we were the first in Canada to have an XRF machine licensed for detecting lead in paints and surface coating materials. We believe that we are at the forefront of most environmental and occupational health and safety issues in Canada. Unfortunately, Trevor passed away in December 2013 and is not here to celebrate this milestone with us, but we know he would be proud of our success and adherence to the strong set of principles and values he set in place.

Trevor Harris & Associates first client was the former Scarborough Board of Education. Since the start of that relationship, we have literally built a diverse client base that includes many of Canada’s leaders in the industrial, commercial and institutional (ICI) community. The strong reputation of our firm is based on the success of our clients, and our ability to provide practical, effective, and timely solutions to what was considered a very complex problem. We are proud of the fact that 35 years later our unwavering commitment to these principles and values is instilled in each of our employees.

We want to take this opportunity to thank all of our clients, employees, and vendors for their great support over the past 35 years. We have been truly fortunate to have been associated and worked with so many wonderful people. We look forward to maintaining old friendships and creating new ones. At THEM we like to treat all as friends. This philosophy is based on the principle that we never let our friends down.

It is our dedicated personnel that have enabled us to maintain our commitment to our clients and suppliers. Obviously, our staff is our most valued asset and we are proud of the commitment that they make to us and to you. We provide consulting services to a variety of academic, industrial, real estate, banking, commercial, and government institutions. We have four (4) full-service offices in Ontario and Quebec to serve the needs of our friends.

For those of you who are not familiar with THEM, our diverse and multidisciplinary organization consists of a team of over 30 well qualified individuals including Certified Industrial Hygienists, Professional Engineers, Environmental Scientists, Engineering Technicians and Technologists, Geologists and Laboratory Technicians. Working with a motivated staff and supported by state-of-the-art technology, we utilize these resources to provide effective solutions as dictated by individual projects. We have the staff and expertise to economically and quickly handle a complete range of environmental and construction materials services, regardless of project size or complexity.

It has been a pleasure serving you for the last 35 years and we look forward to providing you with superior service many more years to come.
