Notes on this record

  • GSDC publishes no current numbered top-employer list. Its 2017 annual report is the latest one found ('Top Employers', public and private); its 2018 and 2020-2024 reports have none, and the 2019 report sits on investsudbury.wpengine.com, whose robots.txt is 'Disallow: /', so it was not opened. 2017 figures are recorded with their year.
  • From the 2017 GSDC list, left out because the employer's own site was not opened: Walmart (400) and G4S Secure Solutions (350; G4S is now part of Allied Universal).
  • Invest Sudbury mining page: the Greater Sudbury mining complex has 'nine operating mines, two mills, two smelters and a nickel refinery' and 'more than 300 mining supply firms employing more than 14,000 people', with about $4 billion in annual exports.
  • Blocked or skipped: Public Health Sudbury & Districts (phsd.ca robots.txt disallows ClaudeBot and anthropic-ai; not fetched, no row); valebasemetals.com (robots disallows ClaudeBot; home page loaded once via redirect before its robots was read, nothing else fetched); laurentian.ca (Incapsula 403); rainbowschools.ca (Cloudflare challenge); kghm.com Sudbury page (403 Access denied), so KGHM's Sudbury operations have no row; tracksandwheels.com (robots disallows AI crawlers; not fetched); Conseil scolaire public du Grand Nord de l'Ontario (cspgno.ca does not resolve; no row); mansourmining.com and technicagroup.com (TLS certificate mismatch; no rows).
  • Two redirect hosts (collegeboreal.ca, fednor.canada.ca) had one page loaded through a redirect before their own robots.txt was read; both robots files allow those paths.
  • Mining-supply firms reported by the press as having Sudbury head offices (Mansour Mining Technologies, McDowell, Normet Canada, Swick) were not added: their own sites could not be opened or did not confirm the head office.
