This is where technically rigorous, forward‑looking solutions are developed to support our clients’ most complex challenges.

Working collaboratively across disciplines, our team delivers integrated sustainability and building performance consulting services for projects in healthcare, industrial facilities, education, civic, commercial, aviation, and large‑scale developments. Our focus is on helping clients make informed decisions around energy systems, low‑carbon pathways, and long‑term building performance, grounded in strong engineering fundamentals.

An opportunity exists in Stantec’s Ottawa, ON office for a Senior Sustainability Consultant with a mechanical engineering background to join our multidisciplinary team. In this role, you will apply your mechanical engineering expertise to support sustainability and energy consulting services, supporting projects through analysis, strategy development, and technical advisory.
