Established in 2001, HDS Environnement quickly distinguished itself through technical excellence. Over the years, the firm solidified its practice by strategically integrating Bio Géo Environnement and merging with Consultation A.D., steadily expanding our fields of expertise and intervention capacity.
In 2017, an internal succession project led by our three current directors ensured a seamless transition and the continuity of our mission. Today, HDS draws on a 25-year corporate history and a reputation built on professionalism and rapid execution.

Our strength lies in a team of experienced professionals, many of whom hold advanced degrees in fields such as engineering, biology, earth sciences, industrial hygiene, and administrative sciences. This diversity allows us to approach every project from multiple angles, offering pragmatic recommendations based on a deep understanding of technical and regulatory challenges.
We complement this internal expertise with strategic alliances with other firms, universities, and research centers, providing access to a global network of 400+ specialists. This enables us to intervene effectively on projects of all sizes across Quebec, Canada, and internationally.
