Our story

It all began during the student strike in 2012. Carl Henri was studying civil engineering at CEGEP, while at the same time working for a company specializing in building demolition and decontamination. He and a friend then decided to start a residential and commercial pressure washing business. MGC was born under the name of MGC Nettoyage haute pression.

From 2014 onwards, the company underwent many changes: it obtained its RBQ license and shifted its focus from the residential sector to construction, heavy industry and civil engineering. MGC took on several major projects, including the Sun Life Building (2017) and the Olympic Stadium (2018).

Launch of major projects and completion of high-profile mandates at MGC, including the revitalization of the prestigious Sun Life Building in Montreal, as well as an abrasive blasting cleaning contract for the renovation of Montreal’s Olympic Stadium.

MGC moved to a larger building in Laval and continued to invest in state-of-the-art equipment. Carl and his team continued to develop and refine techniques, including the use of abrasive blasting to clean buildings, prepare various types of surfaces and upgrade elements.

MGC introduced an environmental clean-up service to deal with emergencies, such as highway spills, and established partnerships with specialized waste management centers across Quebec.

MGC expanded its service offering with the acquisiton of Soleno Service, a South Shore company offering pumping and hydro-excavation services for the construction industry, as well as a concrete hydrodemolition company in the Saguenay.

2024 marks a turning point in the growth of Groupe MGC and the consolidation of its service offerings.The addition of a full division focused on hazardous materials management, along with container rental services—not to mention the 20,000 sq. ft. expansion of the Bois-des-Filion headquarters—demonstrates this strategic evolution.
