What DS Consultants does

DS Consultants Ltd. is an Ontario-based professional engineering consulting firm founded in September 2017 and headquartered in Vaughan, operating across four Ontario offices (Vaughan headquarters and laboratory, Hamilton, Barrie, and Cambridge). The firm delivers six integrated service lines — geotechnical, environmental, hydrogeology, materials testing, building science, and instrumentation & monitoring — to land developers, construction companies, mining operators, and public-sector clients throughout southern Ontario. Its technical capabilities include state-of-the-art real-time cloud-based noise and vibration monitoring units, high-precision survey equipment for settlement/ground/rail-track monitoring, and emerging remediation techniques such as high-resolution site characterization and contaminant forensics. With over 155 trained staff and a track record on landmark projects including the SkyTower at Pinnacle One Yonge (Canada's tallest building), the South Niagara Hospital, and the FORMA development, the firm has scaled materially since inception.

DS Consultants generates revenue through project-based, quote-driven professional services engagements billed to enterprise clients, with no publicly disclosed standard pricing tiers. Go-to-market is sales-led and relationship-driven, supported by LinkedIn presence, published case studies, conference participation (RemTech East, Bureau Veritas Fall Science Summit, ONEIA Business & Policy Forum), and ONEIA membership including brownfields policy engagement with the Ontario Ministry of Environment, Conservation and Parks. The firm holds COR® (Certificate of Recognition) accreditation and has filed over 60 Records of Site Condition with 10 active Risk Assessment projects, reflecting a credentialed safety and regulatory posture that supports bidding on major infrastructure work.

On December 10, 2025, BluMetric Environmental Inc. (TSX: BLM) acquired DS Consultants Ltd. for up to CA$22.5 million in cash and stock with a three-year EBITDA-linked earnout, making DS a wholly-owned subsidiary within BluMetric's environmental consulting and WaterTech platform. Post-acquisition, DS is positioned to extend its environmental professional services into Toronto commercial markets and into the mining sector across Ontario and Quebec, while continuing to operate under the DS Consultants brand. BluMetric's Q1 FY2026 results showed DS contributing CA$1.5M in 20 days of consolidation and Q2 FY2026 showed CA$3.9M, implying a strong-growth revenue contribution and validating the strategic rationale of the combination.
