Trades business licence requirements

To apply for a trade business operating licence you’ll need to submit:

  • A Business Licence Application
  • A copy of your business registration documents
  • Certificate of Insurance (minimum $2 million construction liability completed by your insurance provider)
  • Certificate of Qualification from the Ontario College of Trades
  • A criminal record search for building renovator and paving contractor licences. A criminal record search must be done within 30 days of your application by police services from the municipality you live in.
  • A letter of employment showing at least two years of practical experience for master plumber, heating installer, building renovator and paving contractor licences.
  • Building renovators and drain layers must pass a written exam set by the City with a minimum grade of 70%. You may be exempt if you hold a current licence issued by another municipality in Ontario that required successful completion of a written exam resulting in a valid acceptable certification.
  • Drain Layers who hold a valid Certificate of Qualification from the Ontario College of Trades will be exempt from writing the test.
