The QEDC Top Employers list covers the whole Bay of Quinte Region (Belleville, Quinte West, Brighton) and lists manufacturers only. Rows here are only those whose Belleville location was confirmed on a company or QEDC page.
On the QEDC list but not added because a Belleville site could not be confirmed on a company page in this pass: Lactalis Canada (650; Lactalis closed its Belleville distribution centre in 2025, cheese plant reported to remain), Hanon Systems Canada (438), Sigma Stretch Film (147), Kennametal Stellite (138), Amer Sports Canada (91), APTYX (225). McKesson Canada (437), JBS Ontario (400), Kruger PRO (256), Trenton Cold Storage (208) and Electro Cables (174) are in Quinte West, not Belleville. Redpath Sugar (148) — redpathsugar.com returned 403 Access Denied. W.T. Hawkins Ltd. (Cheezies, 114) — no working company website found (cheezies.ca is a parked lander).
Blocked: Hastings County (hastingscounty.com — Cloudflare challenge); Hastings Prince Edward Public Health (hpeph.ca — connection failed); quinteedc.ca (connection failed; QEDC now publishes at quintedevelopment.com); canadianpackaging.com robots.txt disallows the article used as a lead.
The City's economic-development pages (bellevillebiq.ca) publish no headcounts. No venture-funded software/tech company headquartered in Belleville was found.

Prepared 2026-10-30. Each headcount links to the page it is read from; each company to its own site or its /company page.
