Legal Considerations When Renovating in Toronto

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. For large amounts, Small Claims Court handles claims up to $35,000; Superior Court for larger claims.
