Thurston Machine

What Thurston Machine does

Thurston Machine Company Ltd. is a family-owned, build-to-print industrial manufacturer founded in 1915 in Port Colborne, Ontario, operating two plants totaling more than 160,000 square feet of production space and employing approximately 90 skilled trades professionals. The company runs four integrated service lines: fabrication and welding (including ESAB ICE-technology manipulators and sub-arc systems), precision machining (six TOS WHN CNC horizontal boring mills plus Mazak live-tooling machines), paint, blast and industrial coatings (steel grit blasting with full media reclaim), and assembly and testing (millwright services with a 400-ton horizontal press and FaroArm CMM inspection). Heavy lift infrastructure includes 80-ton overhead cranes, and quality systems are anchored by ISO 9001:2015, CSA N299.3 (nuclear), CWB W47.1 (steel welding), and CWB W47.2 (aluminum welding) certifications.

The company serves enterprise customers in nuclear, mining, OEM manufacturing, steel mill, power generation, and transportation (including aerospace and rail), executing large-scale, quote-priced project contracts on Net 30 terms with progress payments. Turnkey build-to-print work, in-house non-destructive testing, a cross-border trucking fleet, and membership in The Machining Group network (alongside Central Machine, GFW, and Insitu Machining) allow Thurston to operate as a single-source supplier for customers that would otherwise coordinate multiple subcontractors.

The business is privately held with no institutional investment, no public listing, and no disclosed M&A or external funding activity. Revenue, customer mix, and current backlog are not publicly disclosed. Strategic posture has emphasized capital deepening (the 2010 $11M expansion that doubled machining capacity and floor space) and certification breadth (nuclear and welding credentials that gate entry into the most demanding end-markets), rather than geographic or product-line diversification beyond adjacent aerospace and U.S. cross-border work.
