Hiring an unlicensed contractor in Ontario can lead to substandard work, voided warranties, failed inspections, and serious liability issues that cost Ottawa homeowners thousands of dollars to resolve. Unlike some provinces, Ontario does not have a single universal licensing body that covers all types of contractors, which makes the verification process more complex than many homeowners realize. Different trades are regulated by different authorities, and some trades that require licensing in other jurisdictions have no mandatory licensing requirement in Ontario at all. This creates confusion ...
Ontario's approach to contractor licensing is fragmented across multiple regulatory bodies, each overseeing specific trades or scopes of work. There is no single provincial licence that qualifies a person as a general contractor. This is a critical distinction that catches many Ottawa homeowners off guard. The Ontario College of Trades previously served as a central registry for skilled tradespeople, but the organization was dissolved in 2022 and replaced by Skilled Trades Ontario. Understanding...

Beyond provincial trade certifications and safety authority registrations, contractors working in Ottawa must comply with municipal business licensing requirements.

Licence verification is an essential first step but should not be the only check you perform before hiring a contractor in Ottawa.

Ask for a minimum of three references from recent projects similar in scope to yours, and actually contact those references. Ask about the quality of work, adherence to timeline and budget, communication throughout the project, and how the contractor handled any issues that arose. Check online revie...
If you discover during the verification process that a contractor lacks required licensing or certification, the appropriate course of action depends on the timing of your discovery. If you have not yet signed a contract or paid any money, simply do not proceed with that contractor. If you have signed a contract but work has not yet begun, review the contract for cancellation terms and provide written notice of cancellation, citing the contractor's failure to hold required credentials. Under the...
