ORTECH Consulting

What ORTECH Consulting does

ORTECH Consulting Inc. is a Canadian environmental and energy engineering consultancy headquartered in Mississauga, Ontario, with additional offices in Sarnia and Windsor. The firm is described as established around 1982 (one source states 1999) and operates with an 11–50-employee technical team of P.Eng., QSTI and other credentialed engineers, scientists and source-sampling specialists. It serves industrial, government and financial clients across North America and selectively internationally, providing emission testing and source sampling, ambient air monitoring, air quality permitting (Environmental Compliance Approvals, EASR), greenhouse gas reporting (federal and Ontario-specific), odour assessment and renewable energy advisory (solar, wind, energy storage, net metering, due diligence).

The company's technical platform combines proprietary atmospheric instrumentation—including a custom diffusion denuder-based gas/particle sampler for semi-volatile organics and a fully instrumented mobile ambient air monitoring unit—with industry-standard dispersion modelling tools (AERMOD, SCREEN3) and an in-house analytical laboratory for odour and biogas analysis. It also operates the long-running Sarnia-Lambton continuous ambient air monitoring network on behalf of the Sarnia Lambton Environmental Association (SLEA), a consortium of heavy-industry stakeholders—giving it 60+ years of longitudinal air quality data in one of North America's most complex petrochemical airsheds. Beyond traditional air quality work, the firm has built energy and decarbonization practices, delivering independent engineering reviews and Climate Lens Assessments to renewable energy developers, banks and infrastructure investors.

ORTECH is a wholly-owned operating subsidiary of Kontrol Energy Corp. (CSE:KNR, FSE:1K8), and is now presented as an Alliance Technical Group Company following that firm's roll-up activity in 2025. Revenue is generated on a project-based professional services model—quoted, statement-of-work engagements for industrial operators, project developers, municipalities and provincial/federal agencies, with no public pricing tiers—and the go-to-market is consultative, relationship-driven, direct enterprise field sales rather than channel-based.
