Notes on this record

  • Whitby is the seat of the Regional Municipality of Durham, the Durham District School Board and Durham Regional Police. Durham 2025 Business Count: Whitby had 47,571 jobs in 2025 (45,248 in 2024, +5.13%, the fastest growth in Durham). Its Top 10 headcounts are Region-wide bands, not Whitby-only.
  • Rows for multinational sites (Gerdau, Lear, Thermo Fisher, LKQ, AECOM, GHD, WSP, Amazon) rest on Invest Durham's Whitby 'Major Employers' list; each company's own site and careers page was opened, but the Whitby site itself was not confirmed on those pages.
  • Left out because their own sites could not be used: Ontario Shores Centre for Mental Health Sciences (Whitby psychiatric hospital, a major employer per Invest Durham — ontarioshores.ca robots.txt disallows us); Atlantic Packaging (Whitby plant; atlanticpackaging.com did not respond to robots.txt); Elexicon Energy (elexiconenergy.com robots.txt disallows us; its head office is in Ajax anyway).
  • Funded software/tech HQ'd in Whitby: 360insights only. No other funded tech head office was verified.
