The company is a unit of , the multi-technical services group owned by French construction conglomerate Bouygues since 2022. It provides integrated facility management, building automation, energy efficiency, decarbonization and public-private partnership services.
History The company was founded in 1992 as Alizé Gestion Technique d'Immeubles Inc., with its first mandate covering six buildings owned by SITQ in Montreal. During the 1990s, the company expanded its facility management activities across Quebec and developed services in energy management, computerized maintenance management systems (CMMS), and energy performance contracting. In 2001, the company acquired Tri-Air, a company specialising in heating, ventilation, and air conditioning (HVAC) controls. In 2005, Alizé Gestion Technique d'Immeubles was renamed Axima Services. During the same year, the company acquired a 50% interest in Contrôles AC, a Quebec-based building automation company. The company entered the United States market in 2007 with a facility management contract at Louisville Airport. Its U.S. airport operations expanded in 2008 through a contract at Boston Logan International Airport. Following the merger of Gaz de France and Suez, Axima Services was renamed Cofely Services in 2009. After GDF Suez adopted the name Engie in 2016, Cofely Services became Engie Services.
In 2018, Engie Services acquired PBW High Voltage Ltd. and purchased the remaining shares of Contrôles AC, making it a wholly owned subsidiary. During the same year, the company established Engie Transport CM Canada, a joint venture with Engie Inéo to provide electrification and railway infrastructure services in North America.
In July 2021, Engie consolidated its multi-technical services businesses worldwide under the Equans brand, creating a standalone business unit. Later that year, Bouygues signed an agreement to acquire Equans from Engie.
The acquisition of Equans by Bouygues was completed in October 2022 and Engie Services Inc. was renamed Equans Services Inc. In March 2025, Bouygues Energies & Services Canada Limited (BYES Canada) adopted the Equans Services brand.
