The regional control center was expanded in 1994 to accommodate a vast 1,000 square meters - operating room with 7 meters-high ceilings, to host all the screens and IT equipment. A hundred people work there daily. The important innovation in this type of room is the presence of roof lights built according to the strictest technical norms and functional requirements: they bring in natural lights against the walls, so that controllers can have a sense of the time of day and weather, while not bringing direct light onto the work stations. All of the artificial lighting is indirect to reduce glare and ease reading of the surveillance monitor. Following the acquisition of the Center by NAV Canada in 1997, the firm completely refurbished the office spaces for them (3500 square meters).
