Carrière Mont St-Hilaire inc.

What Carrière Mont St-Hilaire inc. does

Carrière Mont St-Hilaire inc. is a Quebec-based aggregate producer operating a single quarry in Sainte-Madeleine on a geologically distinctive site that yields two commercially extractable rock types — syenite (used in road infrastructure, building construction, and landscaping) and hornfels/cornéenne (used as feedstock for roofing shingles). The site covers 341,950 m² and is associated with approximately 400 catalogued mineral species, of which roughly 70 were first identified at the location. Following a September 2015 plant modernization, nameplate crushing capacity exceeds 900 tonnes per hour, described as unique in Quebec, with a reported 12-minute per-truck loading cycle. The product line spans MTQ/municipal-grade infrastructure stone (CG14, MG20 series, MG56 series, MG112), clean classified stone (510 through 100200), large wall stone (300600, 5001000), and recycled MG56R; ancillary services include concrete/asphalt recovery, transport, and on-site weighing, plus an online material calculator and quote-request workflow.

The company sells to three customer segments — contractors (entrepreneurs), municipalities (villes), and individuals (particuliers) — through direct quarry pickup and delivered transport on a quote-driven, per-tonne basis. Pricing includes a winter surcharge of C$1/tonne (January–March) and a municipal royalty of C$0.64/tonne, with availability confirmed per order. The company is privately held as part of Groupe Michaudville, alongside sister firms Les Entreprises Michaudville Inc. (civil engineering) and Foraction Inc. (drilling/trenchless rehabilitation), and holds membership in Quebec industry associations AQEI, ACRGTQ, and RPPG. Operational leadership consists of Julie Phaneuf (Directrice générale) and Renaud Guimond (Directeur des opérations), supported by 20 employees; the company is compliant with Quebec Law 25 on personal information and holds environmental approvals from Quebec's Ministère du Développement durable, de l'Environnement et de la Lutte contre les changements climatiques.
