About Us

Founded by Trevor Harris in 1979, T. Harris Environmental Management Inc. (THEM) has grown from the first asbestos consultancy in Canada to a leading provider of environmental and occupational health and safety management services. With a foundation built on expertise and a passion for health and safety, THEM has continually evolved to meet the changing needs of our clients. 

From our early days, we’ve been driven by a desire to make a positive impact. Trevor, and soon after, John Fisher, recognized the importance of environmental health and safety while the environmental consulting industry was evolving. It is this foresight that has allowed us to stay ahead of the curve and lead the industry in developing innovative solutions to complex environmental challenges.
