Our Clients

It’s not enough to know the science, to do environmental work in the construction industry; you need to understand every client’s situation. Contract obligations, permitting commitments, regulatory requirements and the practicality of control measures all influence what will work and what won’t work at a job-site. GEMS knows what questions to ask, who to talk to, and what needs to happen to keep things moving.

We are proud of the work we do for our clients, that they keep coming back and when they find us because someone has recommended GEMS. They trust us to get something done for them, difficult things, unexpected things and usually things that are not budgeted and getting in the way of what they need to be doing.

Here is a snapshot of some of the clients that trust GEMS


  • In working with GEMS through the first 2 years of our project, we have found their support to be beyond helpful. Our project entails heavy civil work in environmentally sensitive areas, including 'In-Water Works' in an endangered species habitat. As a result, the contract has many restraints in order to comply with MNRF and ESA regulations. GEMS' staff is very knowledgeable in all the regulations and requirements of the contract or third parties and work closely with the contractor to ensure compliance. GEMS play a highly active role in the field and are continuously monitoring activities and ESCs (Erosion and Sediment Control). In today's construction industry, environmental protection measures play a key role in mitigating our ecological footprint and an environmental specialist like GEMS is mandatory to achieve success.

  • It was a pleasure to work with GEMS through the entire duration of the Mississauga Road - Peel Region project in Brampton, ON. GEMS has provided us with various services such as environmental assessments, professional erosion and sediment control recommendations, and fish relocations during active construction. Ross, GEMS' Aquatic Biologist, has always maintained a very high standard of professional knowledge and was readily available for consultation and site visits on short notice.
