Whitby, Ontario, November 3, 2022 – CIMA+, one of Canada’s largest privately-owned consulting engineering firms, today announced the acquisition of Durham Energy Specialist Limited (“DES”), a mechanical and electrical consulting engineering company located in Whitby, Ontario.

“The acquisition of Durham Energy Specialist Limited is a sign of our ongoing commitment to grow our expertise and diversify our operations across Canada, and particularly in the Ontario market,” said Steeve Fiset, Chief Strategy Officer, CIMA+. “Joining forces with DES both adds to and supports our national Buildings practice.”

“Our technical team servicing the Buildings market in Ontario is constantly growing,” said Matt McBride, Vice-President, Buildings, Ontario at CIMA+.  “Through the addition of DES, our clients will now have access to a larger pool of engineering resources and a wider array of expertise under one banner, thanks to our combined team of over 425 employees dedicated to these vital markets.”

DES specializes in efficient engineering design, including new construction and retrofits to existing buildings, with a focus on energy conservation and sustainability. Mechanical engineering specialties include heating, ventilation and air conditioning (HVAC), controls, plumbing, and fire protection.  Electrical engineering services focus on power, lighting, life safety, and communications. By joining forces, CIMA+ and DES leverage complementary strengths, similar cultures and values, and increased value for clients through a wider service offering.

“The ability of CIMA+ to deliver a local, personal approach to supporting their clients’ needs, while leveraging the resources of a large engineering firm, was a major appeal to DES,” said Leanne Skribe, P.Eng., President, DES. “Joining forces with the CIMA+ team is a logical progression to our business and will allow us to better serve our established client base while enabling opportunities to grow.
