Groupe MACO

What Groupe MACO does

Groupe MACO is a privately held industrial construction and maintenance services firm headquartered in Trois-Rivières, Quebec, operating across Quebec and Ontario. The company delivers general contracting, industrial construction, gas network construction and maintenance, turnkey project execution, industrial maintenance and plant shutdowns, tank engineering/fabrication/installation/repair, and workshop fabrication of piping systems and process modules. It serves enterprise clients in four verticals: energy and civil works (gas, hydroelectric, wind, thermal, nuclear), chemicals and petrochemicals, mining and metallurgy, and manufacturing (pulp and paper, cardboard, industrial processing). Named reference customers include Shell, Suncor, Hydro-Québec, Rio Tinto Fer et Titane, Glencore/CCR, Énergir, Valéro Énergie, Kruger, Olin, Cepsa Chimie, WestRock, Viterra, McInnis, and Silicium Québec.

The company's technical offering rests on six specialty trades — piping, civil works, boilermaking, mechanical and millwrighting, steel structures, and directional drilling — supported by in-house workshop facilities for piping prefabrication and modular assembly. Documented execution scale includes 1,100+ peak workers mobilized on a single project (Kruger tissue machine), 375+ process equipment installations on the TRT-ETGO/FGV greenfield, and 75+ gas network upgrade projects. The firm reports a 10-year record without recordable safety events and an OSHA frequency rate below 1 over the same period, and holds the ÉCORESPONSABLE Level 1 certification audited by ECOCERT CANADA.

Groupe MACO generates revenue on a project-based professional services model, with custom quotes per engagement and multi-year contract cadences for major enterprise clients. The go-to-market is direct enterprise field sales — relationship-driven, reputation-led bidding against general-contractor scopes — with no disclosed standard pricing tiers. The company is family-inspired, privately held, and discloses no revenue, funding rounds, M&A activity, or leadership changes in the available material.

Broad incumbents

• Pomerleau: Quebec-headquartered construction firm with strong industrial, civil, and energy-sector capabilities across Eastern Canada. Comparable for turnkey industrial construction, civil works, and mechanical scopes in the Quebec market MACO primarily serves.
• Graham Group: Western Canadian construction firm with an industrial division serving energy, mining, and heavy-industrial clients. Comparable for mechanical, piping, and structural industrial construction scopes; represents a regional peer that could also encroach into Quebec/Ontario markets.
• Aecon Group: Major Canadian construction and infrastructure services company with industrial, utilities, and energy-sector capabilities. Comparable because it delivers mechanical, piping, and civil work for industrial clients in the same Quebec/Ontario corridor where Groupe MACO operates.
• PCL Construction: Large North American general contractor with significant industrial, energy, and manufacturing construction practice. Comparable for the same multi-disciplinary industrial construction scopes (mechanical, piping, structural) on energy, mining, and manufacturing facilities.
• Bird Construction: Canadian construction firm with a substantial industrial maintenance and mechanical services practice following the Stuart Olson acquisition. Directly comparable for industrial maintenance contracts, plant shutdowns, and mechanical/piping work on industrial facilities across Canada.
• AtkinsRéalis (formerly SNC-Lavalin): Canadian-headquartered global EPCM and nuclear services firm with a deep industrial construction and maintenance practice serving energy, chemicals, mining, and infrastructure. Comparable because it competes for similar turnkey industrial scopes in Quebec and Ontario, though at substantially larger scale and broader geographic reach.
• EllisDon: Canadian construction services company with industrial, civil, and mechanical capabilities. Comparable for turnkey industrial construction, mechanical installations, and civil works delivered to enterprise clients across Canada.

Direct peers

• Black & McDonald: Canadian multi-trade contractor specializing in mechanical, electrical, and industrial services for utilities, energy, and industrial clients. Highly comparable because it self-performs industrial maintenance, piping, and construction across similar verticals (energy, petrochemical, manufacturing) in overlapping geographies.
• Bantrel: Canadian-based engineering, procurement, and construction firm (Bechtel affiliate) serving oil & gas, power, and industrial clients. Comparable for the same heavy-industrial mechanical, piping, and structural scopes in the Canadian hydrocarbons and mining sectors.
• Plan Group: Ontario-based specialty mechanical, electrical, and industrial construction services firm serving manufacturing, energy, and institutional clients. Comparable for self-perform mechanical and piping work on industrial facilities in Ontario, MACO's secondary operating geography.
