Inflector Environmental Services

What Inflector Environmental Services does

Inflector Environmental Services is a privately held Canadian hazardous materials remediation and abatement contractor headquartered in Greely (Ottawa), Ontario. Founded in 1994 by Jeffrey Clarke Sr. as a single-person basement operation and led since 2014 by his son Jeffrey W. Clarke Jr., the company delivers asbestos and lead abatement, mould remediation, soil and site remediation, selective demolition, 24/7 emergency environmental response, and (since acquiring Donalco Inc. in February 2023) fireproofing and firestopping services. The firm has executed several of Canada's largest and most politically sensitive abatement projects, including the MacDonald Block reconstruction (described as the largest single abatement project in Canadian history), Parliament Hill rehabilitation, the Government Conference Centre (3,500 tons of asbestos removal in six months), TTC subway stations, and mould remediation at the Museum of Science and Technology requiring protection of 25,000 artifacts.

The business runs on a project-based professional services model: revenue is earned on per-project contracts awarded through competitive tenders from federal, provincial and municipal governments, transit authorities, healthcare and heritage institutions, and commercial/industrial owners. Delivery is supported by Inflector's proprietary patented advanced machinery and hydraulic equipment, a cloud-based document management system, and a workforce of approximately 500-600 employees including 150+ certified emergency response professionals available 24/7. The firm holds Certificate of Recognition (COR) certifications in all five operational provinces, MTCU technician certifications, government security clearances, and prequalifications through Avetta, ISN World, ComplyWorks, and ContractorCheck — collectively forming a high regulatory barrier to entry.

Revenue is generated across three streams: core hazardous materials abatement and demolition (the principal stream), Donalco fireproofing and firestopping services, and 24/7 emergency response. The customer base spans federal/provincial/municipal government agencies, transit commissions, hospitals and children's hospitals, universities, museums, heritage institutions, industrial operators, and commercial real estate owners. Inflector is privately held with a strategic minority equity investment from Fengate Private Equity on behalf of the LiUNA Pension Fund of Central and Eastern Canada (announced September 2022) and operates from nine owned regional offices across Canada (Ottawa, Toronto, Kingston, Halifax/Beechville, Moncton, Conception Bay South, Edmonton, Calgary, and Dorval). It has been recognized as one of Canada's Best Managed Companies in 2022, 2023 and 2024.

Revenue model

1. Hazardous Materials Remediation and Abatement Services: Inflector generates revenue through project-based professional service fees for hazardous materials remediation. Services include asbestos and lead abatement, mould remediation, soil and site remediation, demolition, and emergency response. Clients (government, institutional, commercial, industrial) engage Inflector through competitive tender processes or direct project requests. Revenue is earned on a per-project basis with pricing determined through detailed estimates. This is the company's primary revenue stream.
2. Fireproofing and Firestopping Services (Donalco Division): Following the February 2023 acquisition of Donalco Inc., Inflector expanded into fireproofing and firestopping services for industrial, commercial, and institutional projects. Services include spray-applied fireproofing (cementitious, mineral fibre, intumescent coatings), firestopping installations, and hazardous material waste removal. These services are offered as part of project-based remediation and construction contracts.
3. Emergency Response Services: Inflector's 24/7 emergency response division generates revenue from rapid mobilization to environmental crises including spill response, decontamination, confined space management, and disease control. The company dispatches teams of 150+ certified emergency response professionals on an urgent basis, with pricing based on project scope, timeline, and resource requirements.
