Nearby Contractor License Lookups

Ontario Contractor License Lookup

Use this page when you need a Ontario contractor license lookup, a list of licensed general contractors in Ontario, or a fast way to screen specialty subs before bid award. Each profile starts from CSLB license data and adds federal safety, wage, debarment, environmental, and permit records.

These records cover contractors based in Ontario. The list includes general building contractors and specialty trades, with license number, status, primary classification, and federal record count shown before you open a full profile.

Of the 952 CSLB-registered contractors in Ontario, 95% hold active licenses and 44 have at least one record in federal databases. For GCs verifying subs, that means a standard CSLB status check is only the first pass; the risk review also needs workers' comp, bond, SAM.gov, OSHA, DOL, EPA, and permit checks.

What to Check for Ontario Contractors

  • CSLB License: Confirm Active status (not Suspended, Revoked, or Expired)
  • Workers' Comp: Verify current coverage; exempt status means no employees
  • Contractor Bond: California requires $25,000 minimum (SB 607, Jan 2023)
  • Federal Debarment: Search SAM.gov for exclusion records
  • Safety & Wage History: Check OSHA citations and DOL wage violations

Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
