Notes on this record
- Deepened 2026-10-29 from 5 to 20 rows. Headcounts remain scarce: only PowerCo (200+) and Takumi (300+) publish a St. Thomas figure; no top-employer list was reachable (EDC /stats.html is robots-disallowed).
- PowerCo: powerco.ca and powerco.de both have robots.txt 'Disallow: /' for all agents, so the PowerCo site was not opened. Facts come from PowerCo Canada's own release as reposted by the City of St. Thomas, and from the St. Thomas EDC repost of its 24 Sep 2026 release. Government of Canada/Ontario job figures were not read first-hand. Secondary reports of 'up to 3,000 direct jobs' (2023) were not confirmed and are not recorded.
- PowerCo and Vianode are both at Yarmouth Yards Industrial Park, which the EDC describes as St. Thomas' newest industrial park. The EDC says its rail facility is being built 'right next to the PowerCo gigafactory site in St. Thomas'.
- Magna: magna.com loads, but no page there was found naming the St. Thomas plant. The division and description come from the Chamber of Commerce member listing.
- Drone company (Jim's lead): re-checked 2026-10-29 — the St. Thomas EDC news archive (all 248 sitemap URLs), City news, and Ontario/Canada announcements found via search name no drone or UAV company setting up in St. Thomas. The EDC's 'droneviews' pages are its own drone footage of Yarmouth Yards construction, and the only aviation business story (EDC, 30 Apr 2025, 'Business Takes Flight at St. Thomas Municipal Airport') covers aircraft maintenance and flight training (Smart Aviation Maintenance, Purple Hill Air, Maple Wings Flight Centre) — not drones. smartams.ca returned HTTP 403 for robots.txt, so it was not opened. Not recorded; Jim, if you have the company's name, it can be checked directly.
- The St. Thomas EDC statistics page (/stats.html, which may hold a top-employer list) is Disallowed in robots.txt and was not fetched. The EDC community profile PDF downloaded but would not parse.
- Chamber directory leads not added (small, or outside the city): Steelway Building Systems is in Aylmer; Muma Manufacturing (site would not connect), Forest City Castings (robots.txt 403), plus several small machine shops.
- Ford St. Thomas Assembly (closed 2011), Sterling/Freightliner (closed) and GKN Sinter Metals (closure announced 2020) are former employers and are not listed.
- St. Thomas Elgin General Hospital headcount: a search snippet attributed 'over 1,000 staff, 230 physicians' to the Chamber listing, but the listing as fetched did not contain it; left null.
- 2026-10-31: the "drone company" Jim heard about is still unconfirmed. ARA Robotics (ara-uas.com) checked: its own contact, about and careers pages give only Montréal (no St. Thomas site). Red Bird Imaging: no official page found. Leave out until a company or City page names a St. Thomas site.
