Who applies

The individual tradesperson applies for the master’s licence; the business owner applies for the contractor’s licence. The listed fields are plumbing, heating/ventilation/air conditioning, drain laying, building repair and sprinkler/fire protection.

The bylaw describes an exemption for work on buildings designed by and under supervision and review of an Ontario-licensed architect or engineer. Confirm whether the actual project meets it; a professional involved elsewhere does not automatically exempt all jobs.

Application evidence

Complete the Business/Trade application and Trade Licence Questionnaire. New applicants may need insurance, business registration or corporate profile and photo ID. Required documents depend on the trade category.

Renewals require insurance, photo identification and a declaration about criminal convictions since initial issue. Refer to the Business Licence Reference Guide for category-specific details rather than assuming one checklist fits every trade.

Exams and payment

Building Repair and Drain Laying require a trade exam before issue. Apply before the exam date; same-day applications are not accepted. Exams are listed for the second Wednesday monthly at City Hall Rooms 192 and 193, with sign-in encouraged at 5:45 pm and writing at 6 pm.

Online fee payment needs the application number for a new licence or licence number for renewal. The overview does not give a single fee for all trades.

Expiry, checks and help

Licences expire one year after issue and must be renewed annually even if a reminder does not arrive. Inspectors check job sites and Building requests the relevant trade number on permit applications.

Call Licensing at 905-546-2782 option 2. The page has inconsistent East/West City Hall address wording; confirm the correct visit details rather than following the erroneous direction. The main contact section gives 71 Main Street West.
