About Us
Chorley + Bisset Ltd. is a mechanical and electrical consulting engineering company. Our company was established in London, ON, in 1973 by George Chorley and John Bisset. We have provided services for thousands of institutional, academic, industrial, and commercial building projects.

We aim to deliver professional engineering services that efficiently meet our Clients' technical requirements and high expectations for quality and value.Our Ottawa Office
Our first project in Ottawa, the Steacie Superlab at Carleton University, was completed in 2007. This $3.5 million laboratory upgrade was the beginning of our professional relationship with the university, which has since grown to include a variety of new builds and renovation projects. In 2015, we opened an office in Ottawa to serve Carleton University and seek other work in the capital region. We are looking forward to further expanding the office.Our Team
Our current staff size is 45. We have 10 registered Professional Engineers on staff, including 5 Designated Consulting Engineers. Seven of our senior staff are LEED Accredited Professionals. This high ratio of professionals to staff translates into the delivery of a particularly professional service to our clients. John Bisset remains active in the firm, mainly involved in special projects. Everyone on our management team is actively involved in engineering. We believe ownership is strongly linked to the quality of our engineering services. A cornerstone of our ownership structure is the ongoing process of senior management succession, ensuring that the company’s quality and culture have a broad base within the shareholder group. Ownership of Chorley + Bisset is currently distributed among more than a dozen shareholders, all of which are employees of the company.Derek Vakaras
