Most renovation projects go smoothly — but understanding the legal framework protects you when things don't go as planned. Here's what Toronto homeowners need to know before signing with a contractor for a home renovation.
Protecting Yourself Legally During a Renovation
Most renovation projects go smoothly — but understanding the legal framework protects you when things don't go as planned. Here's what Toronto homeowners need to know.
Always Use a Written Contract
A verbal agreement is not enforceable in Ontario for construction work. Your contract should include: detailed scope of work, total price, payment schedule, timeline, material specifications, warranty terms, and a change order process. Never let a contractor start work without a signed contract.
The Construction Act (Ontario)
Ontario's Construction Act gives contractors, subcontractors, and suppliers the right to register a lien against your property if they aren't paid. This lien can complicate your ability to sell or refinance. Protect yourself by paying subcontractors and suppliers directly when possible, or using a lawyer's trust account on large projects.
Holdback Requirements
Ontario law requires homeowners to hold back 10% of each payment until the lien period expires (typically 60 days after substantial completion). This holdback protects you against unpaid subcontractors registering liens on your property.
Contractor Licensing
Ontario does not have a universal contractor licensing requirement, but electricians (ESA), plumbers, and gas fitters must be licensed. Always verify licences for trades that require them, and ask for proof of insurance and WSIB coverage from your general contractor.
Dispute Resolution
If a dispute arises, attempt resolution directly with the contractor first. Document everything — photos, emails, texts. If needed, the Ontario Licence Appeal Tribunal handles some contractor disputes. The right venue depends on the amount in question:
| Path | Claim size | Best for |
|---|---|---|
| Direct negotiation | Any | First step — fastest, cheapest |
| Licence Appeal Tribunal | Varies | Certain contractor disputes |
| Small Claims Court | Up to $35,000 | Most homeowner disputes |
| Superior Court | Over $35,000 | Large or complex claims |
