You hired a contractor to renovate your kitchen, repair your roof, or finish your basement. You paid a deposit, perhaps a significant one. And now, weeks or months later, the work is incomplete, the quality is far below what was promised, or the contractor has stopped returning your calls entirely.
If this situation sounds familiar, you are not alone. Contractor disputes are among the most common civil matters brought before Ontario’s Small Claims Court, and they affect homeowners throughout the Greater Toronto Area every year. The good news is that the law provides you with a meaningful path to compensation, and with Ontario’s Small Claims Court limit now at $50,000 as of October 1, 2025, a broader range of renovation disputes can be resolved through this accessible and cost-effective venue than ever before.
This guide explains when and how you can sue a contractor in Ontario’s Small Claims Court, what you need to prove your case, and what steps to take right now if you have been left with unfinished work, shoddy craftsmanship, or an unpaid refund.

What Types of Contractor Disputes Can Be Resolved in Small Claims Court?
Small Claims Court is well-suited to a wide range of homeowner and contractor disputes. The most common scenarios our clients bring to us include the following.
Incomplete work: The contractor accepted payment (in full or in part) and abandoned the project before completing the agreed-upon scope of work. This is one of the most frequently litigated contractor disputes in the GTA.
Poor workmanship: The contractor completed the work, but the quality falls significantly below the standard that was promised or that a reasonable person would expect. This includes structural issues, cosmetic deficiencies, code violations, and work that requires remediation by a second contractor.
Failure to refund a deposit: The contractor accepted a deposit for work that was never started, or that was started and abandoned, and has refused to return the funds.
Overcharging or unauthorized charges: The final invoice significantly exceeds the agreed-upon price without a valid reason, or the contractor has billed for work that was never authorized or performed.
Property damage: The contractor caused damage to your home or property in the course of performing the work, and has refused to compensate you for the cost of repair.
If your situation falls into one of these categories and the amount in dispute is $50,000 or less, Small Claims Court is almost certainly your most practical and cost-effective legal option.
What Do You Need to Prove Your Case?
Winning a contractor dispute in Small Claims Court requires more than simply telling your side of the story. The court operates on evidence, and the strength of your documentation is one of the most significant factors in the outcome of your case.
To succeed, you will generally need to demonstrate three things: that a contract existed between you and the contractor, that the contractor failed to fulfill their obligations under that contract, and that you suffered a financial loss as a result. Here is what that looks like in practice.
Proof of the contract: This does not necessarily require a formal written agreement, though a written contract is always the strongest evidence. Text messages, emails, and written quotes that were accepted can all establish the terms of an agreement. Even verbal contracts are legally enforceable in Ontario, though they are more difficult to prove without supporting documentation.
Proof of payment: Bank records, e-transfer confirmations, cheque copies, and receipts all establish what you paid and when. Organizing a clear payment history is an essential part of your case file.
Evidence of the deficiency: Photographs and video footage of incomplete or substandard work are among the most compelling forms of evidence in contractor disputes. Document everything thoroughly, and do so as soon as you identify the problem. Time-stamped photos taken before any remediation work is done are particularly valuable.
A second opinion or independent assessment: An estimate or written assessment from a licensed second contractor detailing the cost to complete or repair the work is a powerful piece of evidence. It gives the court a concrete, independent dollar figure for the loss you have suffered.
Written communications: Emails, text messages, and letters between you and the contractor, particularly any in which the contractor acknowledges the problem, makes promises they did not keep, or refuses to respond are important supporting evidence.
The more organized and thorough your documentation, the more persuasively your case can be presented. This is an area where experienced legal representation makes a genuine difference.
Steps to Take Before Filing a Claim
Before filing a Small Claims Court claim against a contractor, there are several practical steps you should take to strengthen your position and demonstrate that you acted reasonably.
Put your complaints in writing. If you have not already done so, send a written notice to the contractor (by email is fine) clearly setting out the nature of your complaint, what you are requesting (completion of work, a refund, or compensation for repairs), and a reasonable deadline for a response. This creates a paper trail and demonstrates good faith on your part.
Obtain a second contractor assessment. As noted above, a written estimate from a licensed contractor outlining the cost to complete or repair the work is one of the most important pieces of evidence you can have. Obtain this before filing your claim.
Check for licensing and insurance. If the contractor was required to be licensed or registered under Ontario law and was not, this is a relevant fact for your case. Similarly, if the contractor carried liability insurance, it may affect how a judgment against them can be enforced.
Calculate your damages accurately. Your claim should reflect your actual, documented financial loss. This includes the cost of incomplete or remedial work based on your second contractor assessment, the amount of any unrefunded deposits, and any other out-of-pocket expenses directly caused by the contractor’s failure to perform. Overstating your damages can undermine your credibility before the court.

What Is the Statute of Limitations for a Contractor Dispute?
In Ontario, the general limitation period for civil claims is two years from the date you discovered (or reasonably ought to have discovered) the loss or harm. For contractor disputes, this typically means two years from the date the work was completed (or abandoned) and the deficiency became apparent.
If you are approaching the two-year mark from the date of your dispute, it is essential to seek legal advice and file your claim promptly. Missing the limitation period means losing your right to pursue the matter in court entirely, regardless of how valid your claim may be.
What Happens After You File?
Once you file your Plaintiff’s Claim with the Small Claims Court, the contractor (as the defendant) has 20 days to file a Defence. If no defence is filed, you may be entitled to request a default judgment. If a defence is filed, the matter will proceed to a settlement conference, a meeting facilitated by a judge or deputy judge with the goal of resolving the dispute without proceeding to trial.
Many contractor disputes are resolved at the settlement conference stage, particularly where the evidence is clear and well-organized. If the matter is not resolved at the conference, it will be scheduled for trial, where both parties present their full case before a deputy judge who issues a binding decision.
