Callidus Engineering is a professional engineering firm with offices located in London, Kingston and Kitchener, ON. We provide mechanical and electrical engineering services to an ever expanding group of clients in Southwestern and Eastern Ontario. Our mission is to provide an excellent engineering product coupled with exceptional customer service. The company goal is to develop and maintain a strong profile in the mechanical and electrical consulting engineering field. To this end, we are committed to the growth and development of our client base and to the personal growth and development of our staff. Callidus (latin for ‘experienced’) formed in 2005 as consolidation of two established and successful companies J.E.D. Engineering (since 1992) and M.G.G. Engineering (since 1993). After years of collaboration on numerous projects, owners Grant Hall and Michael Gubesch decided to combine work forces to form a strong and well-rounded team of engineers. They also welcomed Matthew Van Gilst as a principal of the firm.
