Notes on this record

  • 'Invest in Guelph' is the City of Guelph Economic Development office (guelph.ca/business); investinguelph.ca does not resolve. guelph.ca robots allows these paths. It publishes no top-employers list with headcounts — the 2024 Employment Survey says only that 6 of Guelph's 10 largest employers responded, without naming them.
  • Canadian Solar is NOT a Guelph HQ: its own About page lists 'Canada – Global Headquarters' in Kitchener, Ontario (it is in the ca-kitchener scope).
  • Left out because their own sites could not be opened: Homewood Health (homewoodhealth.com 403 on robots.txt; Mediacorp 2026 lists 1,128 full-time and 328 part-time employees in Canada, with Guelph among major Canadian locations), DENSO Manufacturing Canada (denso.com 403), Cargill (cargill.ca 403), Hammond Manufacturing (hammfg.com 403 on home page), NSF Canada (nsf.org 403 on page). Polycon (Magna) and Skyjack (a Linamar company) were not confirmed in Guelph on the pages read.
  • Linamar's own site is behind a Sucuri challenge; its Guelph worldwide HQ rests on the ISED Canada release of 28 Jan 2025 ('Linamar Corporation is a Canadian company headquartered in Guelph, Ontario').
  • Process slips, disclosed: guessed canadastop100 URLs redirected to eluta.ca (robots not read first) and to canadastop100 /sandbox (a disallowed path); those responses were discarded and not used. www.uoguelph.ca/irp redirected to irp.uoguelph.ca before its robots.txt was read; it was read immediately after and allows the paths used.
