What Roberts Onsite does

Roberts Onsite Inc. is one of Ontario's largest multi-trade contractors, founded in 1938 as Roberts Electric and headquartered in Kitchener, Ontario. Since 2011 it has operated as a wholly owned subsidiary of Black & McDonald Limited. The company delivers turn-key construction, installation, and maintenance solutions across seven core disciplines — electrical, communications, automation controls and engineering, millwrighting and rigging, mechanical (with in-house Yellow Label certified pipe fabrication), preventative maintenance, and utilities and traffic controls. It serves industrial manufacturers (including automotive Tier 1 suppliers such as Denso Manufacturing and Vari-Form), food & beverage processors, healthcare facilities (e.g., St. Mary's General Hospital), higher education institutions (University of Waterloo, University of Guelph), and energy/utility clients across Southern Ontario.

The company's technical platform combines conventional multi-trade construction services with select industrial automation and digital capabilities. In-house fabrication assets include a QPS-certified control panel shop enabling modular plug-and-play wiring assemblies, a Yellow Label certified pipe fabrication shop for high-pressure stainless steel work, and BIM/VDC planning used in project optimization. Operational technology capabilities include predictive maintenance using vibration, temperature, and flow sensor data; an Energy Monitoring and Targeting System (EMTS); infrared thermography for anomaly detection; and automated process control systems (e.g., for Icynene spray foam batching and greenhouse HVAC). The firm has logged 140,000 automation programming hours over six years and installed 2,000+ robots over its history.

Roberts Onsite generates revenue primarily through project-based construction contracts (fixed-price and time-and-materials) supplemented by recurring preventative maintenance agreements and 24-hour emergency service. Go-to-market is exclusively direct enterprise field sales targeting industrial, commercial, and institutional buyers, with a single-point-of-contact model that bundles multiple trades under one contract. The company does not disclose pricing publicly; available compensation signals include a $55K-$70K CAD Project Coordinator range and a $100K-$140K CAD Mechanical Project Manager range.
