Taking a Contract Dispute to Small Claims Court in Ontario

Ontario’s Small Claims Court is a branch of the Superior Court of Justice built to resolve smaller money disputes quickly, affordably, and without the full formality of a standard civil trial. A large share of what it hears is exactly this kind of dispute: unpaid invoices, deposits that weren’t returned, work that wasn’t finished or wasn’t done to the agreed standard, goods that were never delivered, or a contract that one side says the other broke.

The appeal of Small Claims Court is proportionality. Litigation in the Superior Court of Justice can take years and cost far more in legal fees than many disputes are actually worth, which effectively locks smaller claims out of the system unless there’s a cheaper path. Small Claims Court is that path — simplified forms, lower fees, and a process designed to be usable without a lawyer, covered in more detail throughout our contract disputes hub.

It’s not only individuals who use this court. Small and medium-sized businesses rely on it heavily for unpaid invoices and contract disputes that fall under the monetary limit, since the cost of pursuing a claim in a higher court would often exceed the amount actually owed. Landlords, contractors, suppliers, and service providers are all common users of the court for exactly this reason — it’s generally the most practical venue whenever the amount in dispute is modest relative to legal fees elsewhere.

The defining feature of Small Claims Court is its monetary limit: $35,000, not including interest and court costs. If your claim is worth more than that, you have a choice — sue for exactly $35,000 in Small Claims Court and accept that as the maximum recovery, or file in the Superior Court of Justice instead, which has no dollar ceiling but comes with more formal procedure and typically higher legal costs.

For many individuals and small businesses, $35,000 comfortably covers the kind of dispute that actually comes up — an unpaid invoice, a contractor dispute, a holdback or deposit disagreement — which is part of why Small Claims Court handles such a large volume of contract-related cases in Ontario each year.

A Small Claims case starts with a document called a Plaintiff’s Claim. It identifies the parties, states the amount being claimed, and includes a short, plain-language explanation of what happened and why the defendant owes the money. It doesn’t need to read like a formal legal pleading, but it should be specific enough that the defendant understands exactly what’s being alleged.

The claim can generally be filed online through Ontario’s court services portal, by mail, or in person at the Small Claims Court office for the region where the defendant lives, carries on business, or where the events underlying the claim occurred. Once filed and issued by the court, the claim must be served on the defendant, who then has a set period — typically around 20 days — to file a defence. If no defence is filed, the plaintiff can generally request that the defendant be noted in default, often leading to a judgment without a full hearing.

Small Claims Court is deliberately cheaper than higher courts, but it isn’t free. There’s a filing fee to start the claim, generally in the low hundreds of dollars, with additional fees at later stages — for example, when setting the matter down for trial. Fees are generally lower for claims filed online. Parties who can demonstrate financial hardship may be able to apply for a fee waiver.

Beyond court fees, there may be costs for serving documents (using a process server or courier, for instance), obtaining copies of records, and, if you choose to use one, a lawyer’s or paralegal’s fees. The successful party can sometimes recover a portion of these costs from the losing side, but Small Claims Court cost awards are modest compared to higher courts, which is part of the trade-off for a simpler, less expensive process overall.

Small Claims Court doesn’t have the formal discovery process used in higher courts, so the evidence you bring to the settlement conference and trial is largely what you gather yourself beforehand. For a contract dispute, that generally means the contract itself, or — if the agreement was verbal — your best written record of what was agreed, supported by anything else that corroborates it.

Useful supporting evidence typically includes emails, text messages, invoices, receipts, photos of defective work or undelivered goods, bank or payment records, and a clear, itemized calculation of the loss being claimed. If a witness has first-hand knowledge of something relevant — a conversation, an inspection, a delivery — they can be asked to testify, generally after being properly notified ahead of the hearing date. Organized, well-labelled documents tend to carry real weight with a deputy judge who may be hearing many cases in a single day.

It helps to prepare a short, chronological summary of events before the settlement conference or trial, rather than relying on a judge or deputy judge to piece the story together from a stack of documents. Numbering exhibits, putting dates on everything, and separating “what was promised” from “what actually happened” tends to make a claim easier to follow — and a claim that’s easy to follow is generally easier to decide in your favour, assuming the underlying facts support it.

Before a Small Claims case reaches trial, the parties are generally required to attend a settlement conference. This is an informal meeting, usually with a judge or deputy judge, aimed at exploring whether the dispute can be resolved without a trial. It isn’t a trial itself — no final decision is made there — but it’s often where a realistic sense of each side’s strengths and weaknesses starts to emerge, and a meaningful share of cases settle at this stage.

If the matter doesn’t settle, it proceeds to trial, which in Small Claims Court is considerably less formal than in higher courts. There’s generally no jury, the rules of evidence are relaxed, and a deputy judge typically hears the case and may give a decision the same day or shortly after. A demand letter sent before filing can sometimes avoid this whole process if it prompts a resolution early.

Before an appeal is even on the table, it’s worth understanding what a judgment actually gives you. A judgment is a court’s formal decision that one party owes the other a specific amount — it’s a legal entitlement to that money, but it isn’t the money itself. Turning a judgment into actual payment is a separate step, and one that catches a lot of successful plaintiffs off guard.

Appeal rights from Small Claims Court are narrower than from a Superior Court trial. Generally, an appeal to the Superior Court of Justice is only available where the amount in dispute is above a set threshold, or where the appeal raises a genuine error of law rather than simple disagreement with the result. The window to file an appeal is short, so it’s worth checking the applicable deadline promptly if the outcome seems genuinely wrong on the law.

Winning a judgment also doesn’t guarantee payment. If the losing party doesn’t pay voluntarily, the winning party generally needs to take further enforcement steps — garnishing wages or bank accounts, or registering the judgment against real property, for example. It’s also worth keeping Ontario’s limitation period for contract claims in mind before filing, since acting promptly after a dispute arises generally preserves more options than waiting.
