What Habitations Mont-Carleton does

Habitations Mont-Carleton, operating as HMC Modulaire, is a Quebec-based modular construction company founded in 1992 in Carleton and acquired by diversified family conglomerate Groupe Rioux in March 2022. The company designs, factory-fabricates, transports, and installs prefabricated building modules — primarily single-family homes (over 50 standardized models ranging from compact mini-houses to two-story dwellings), multi-residential buildings, and commercial structures (hotels, retail, offices, mixed-use). Manufacturing is concentrated in factory-controlled facilities in Carleton, Maria, and Matane (the third plant acquired in June 2024 and scheduled to begin operations in Q1 2025), with the Matane site strategically positioned near a deep-water port and rail line for regional distribution and potential export.

The core technology is industrial modular construction: modules are built in factory environments with claimed precision tolerances of 1mm and over 100 quality control checkpoints per module, then delivered and assembled on-site. The company markets quantified performance gains versus traditional construction — up to 50% faster build time, 70%+ fewer on-site defects, 30–40% less construction waste, and 25–30% lower carbon footprint — under a three-phase service model (Conception, Fabrication, Installation). Revenue is generated through project-based hardware sales (per-project quotation); pricing is not publicly disclosed and customers initiate quotes through the website.

Go-to-market is split between enterprise field sales targeting government and institutional clients via public tenders (e.g., PHAQ, SHQ affordable housing programs) and direct sales to residential buyers and commercial developers. HMC has secured the first PHAQ project in Quebec (40 affordable housing units at Fermont) and an SHQ pilot (10 modular homes for healthcare workers in Gaspésie), and received $1.5M CAD from the federal Regional Homebuilding Innovation Initiative (RHII) in October 2024 to scale prefabrication capacity. Operations are currently regional (Quebec and Eastern Canada); the company is privately held within Groupe Rioux and does not publicly report revenue.
