Notes on this record
- No published ranked 'top employers' list could be read: the former economic-development site peterboroughed.ca returned a Cloudflare 'Attention Required' block, and investptbo.ca now redirects to the City's economic-development pages, which carry no headcounts.
- Blocked / skipped: Peterborough Victoria Northumberland and Clarington Catholic District School Board (pvnccdsb.on.ca, Cloudflare challenge — not added because its site could not be opened); Five Counties Children's Centre (robots.txt disallows ClaudeBot); mining.com (403).
- The City's Key Sectors page also names Rolls-Royce (its Peterborough naval-handling site has passed to Fairbanks Morse Defense) and 'ACF Associates' (not verified, not added). City says the aerospace sector at Peterborough Regional Airport has 20+ businesses employing more than 500 people.
- No venture-funded software/tech company headquartered in Peterborough could be verified from a company or investor source in this pass.
