What Groupe Madysta does
Groupe Madysta is a privately held, founder-owned Canadian infrastructure services group headquartered in Trois-Rivières, Québec, founded in 1996 as Madysta Constructions Ltée. The company delivers engineering, steel fabrication, construction, and maintenance services to telecommunications carriers, electric utilities, broadcasters, governments, and private enterprises. Its customer roster includes Canada's four largest telecom carriers (Bell, Rogers, Telus, Vidéotron), the provincial utility Hydro-Québec, and Radio-Canada.
The operating model is built around 14 wholly owned divisions that together provide single-source project delivery: engineering (Medesa), steel fabrication and manufacturing (Captel, Acier St-Arnaud), general construction (Madysta Constructions, Les Constructions Casama), telecommunications deployment (Madysta Télécom, Madysta Telecom USA, Azimuth Télécom Services, Gesma Télécom, MDT Télécom), electrical work (DVEM Électrique), HVAC (DMC Climatisation), equipment rental (Location St-Arnaud), and IT services (Qosma Informatique). Captel operates a steel fabrication facility at 9395 Boul. Parent in Trois-Rivières, and ISO 9001:2015 certification from Intertek covers Captel, Medesa, and Madysta Construction for quality-managed internal processes.
The commercial model is project-based and quote-driven, with revenue generated through enterprise and government contracts for telecom tower deployment, energy infrastructure, and building systems. The group sells primarily through direct, relationship-based enterprise field sales. Operations span 8 office locations across 6 Canadian provinces (Québec, Ontario, British Columbia) and a US presence in Thomasville, North Carolina. The company remains privately controlled, with no external private equity, venture capital, or institutional investor involvement disclosed, and no revenue figure is publicly reported.
