Small Claims Court in Ontario: A Step-by-Step Roadmap

From "someone owes me money" to a paid judgment — the whole journey, mapped for self-represented people.

Who this is for: Anyone in Ontario thinking about suing — or being sued — over money or property in the Small Claims Court. You'll get the full sequence of phases in order, who does what at each stage, what you need to prepare, and a sense of timing, so you can move through the process without getting lost.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

Ontario's Small Claims Court is a branch of the Superior Court of Justice built to be navigable by ordinary people. The rules are simpler than the higher court, the language is plainer, and you're allowed to represent yourself. That said, "simpler" is not the same as "simple." A claim still moves through a fixed set of stages, each with its own forms, deadlines, and chances to win or lose. This roadmap walks you through all of them.

A few things to hold in mind before you start:

• Costs and timing vary with the court location, how busy it is, whether the other side fights, and the complexity of your dispute. Treat every timeframe here as "typical — confirm with the court."
• Court forms and filing fees are set by the Ministry of the Attorney General and change from time to time. Get the current forms from the Ontario Court Services / Ontario.ca website and confirm the current fees before you file.
• The monetary limit matters. Small Claims Court can only hear disputes up to a set dollar ceiling — $50,000 as of 2026, exclusive of interest and costs (raised from $35,000 for claims issued on or after October 1, 2025). That ceiling is adjusted periodically, so verify the current monetary limit before you file — if your claim is worth more, you either sue in the Superior Court or agree to give up (waive) the excess to stay in Small Claims.

Timeline at a glance

Phase 0 — Confirm this is the right path

What happens: Before you spend a dollar or fill in a single form, you run three checks. Getting any of them wrong can sink an otherwise good claim.

1. Is Small Claims Court the right court? Small Claims handles most disputes about money owed or the return of personal property — unpaid invoices, bad renovations, unreturned deposits, small contract breaches, property damage. It does not handle everything. Some matters belong elsewhere: residential landlord-and-tenant disputes generally go to the Landlord and Tenant Board under the Residential Tenancies Act, 2006; certain family, estate, and title matters go to other courts or tribunals. If you're unsure where your dispute belongs, ask a lawyer — filing in the wrong forum wastes time and money.

2. Is it within the monetary limit? Add up everything you're claiming. If the total sits at or below the current Small Claims ceiling, you're in the right place. If it's over, decide whether to waive (give up) the amount above the limit to stay in Small Claims, or sue in the Superior Court instead.

⚠️ Watch out: You generally can't split one claim into two smaller suits just to fit under the limit. Courts frown on that.

3. Is it within the limitation period? Ontario's Limitations Act, 2002 sets a deadline to sue. Once it passes, your claim is usually barred no matter how strong it is. The clock typically starts when you knew (or reasonably should have known) you had a claim. The basic limitation period is two years from the day the claim was discovered (Limitations Act, 2002, s. 4) — some claims run on different clocks, so verify how the deadline applies to your facts before you rely on it. When in doubt, treat the deadline as urgent and get advice early.

✅ You're done with this phase when you've confirmed Small Claims is the right forum, your claim fits the current monetary limit (or you've decided to waive the excess), and you're comfortably inside the limitation period.

Phase 1 — Try to resolve it first / send a demand letter

What happens: Before suing, you make a clear, documented attempt to settle. Most disputes that can settle, settle here — it's cheaper and faster than court for everyone.

Who does it: You (or your lawyer).

What you need: A short, factual demand letter — a written notice that sets out who owes what, why, and by when, and warns that you'll commence a claim if it isn't resolved. Keep it calm and specific. (Treadstone has a separate guide on writing a strong demand letter and a fill-in template.)

Why it matters: A demand letter often gets you paid without a single filing fee. Even if it doesn't, it shows the court you acted reasonably, and it pins down the other side's position in writing.

✅ You're done with this phase when you've given the other side a fair, written chance to resolve things — and a deadline has passed without resolution.

Phase 2 — Issue the Plaintiff's Claim

What happens: You start the lawsuit by completing and filing the Plaintiff's Claim form. This is the document that tells the court and the defendant exactly what you're claiming and why. The court "issues" it (stamps and assigns a file number).

Who does it: You file; the court issues.

What you need:

• The correct, current Plaintiff's Claim form
• The full legal name and address of every defendant (an individual's correct legal name; a corporation's exact registered name — check Ontario's business registry)
• A clear statement of what happened, what you want, and how much (the amount, plus interest and costs you're asking for)
• Copies of the key documents you're relying on (contracts, invoices, photos)
• The filing fee (confirm the current amount)

💡 Tip: Name the right defendant. Suing "Joe's Reno" when the business is actually "1234567 Ontario Inc." can mean a judgment you can't collect. Confirm the legal name before you file.

Where to file: Generally in the territorial division where the events happened or where a defendant lives or carries on business. You can often file online or in person at a Small Claims Court counter.

✅ You're done with this phase when the court has issued your claim and given you a court file number.

Phase 3 — Serve the defendant

What happens: You formally deliver ("serve") the issued claim on each defendant so they have proper notice. A lawsuit can't proceed against someone who wasn't properly served.

Who does it: You, or someone you arrange (often a process server). The rules say who can serve and how.

What you need:

• The issued Plaintiff's Claim and attachments
• A valid method of service allowed by the rules (personal service on individuals; specific methods for corporations)
• Proof of service — you'll complete an Affidavit of Service recording when, where, and how you served, and file it with the court

⚠️ Watch out: Serve within the time the rules allow after issuing, and serve correctly. Bad service is one of the most common reasons cases stall. If you can't locate or serve a defendant, ask a lawyer about your options (such as a motion for substituted service).

✅ You're done with this phase when every defendant has been properly served and your Affidavit of Service is filed.

Phase 4 — The defendant's Defence

What happens: A served defendant has a set number of days to file and serve a Defence — their written response. They might admit the claim, dispute it, or raise a Defendant's Claim (their own claim back against you, sometimes called a counterclaim).

Who does it: The defendant.

What you need to do: Watch the deadline.

• If the defendant files a Defence, the case proceeds toward a settlement conference.
• If the defendant does nothing by the deadline, you may be able to ask the court to "note them in default" and move toward default judgment. The exact steps depend on whether your claim is for a fixed sum (a "liquidated" amount, like an unpaid invoice) or something that needs to be assessed.

💡 Tip: Don't assume silence equals victory. Default judgment still requires the right forms and proof. Follow the court's process.

✅ You're done with this phase when the defendant has filed a Defence (the case continues) or the deadline has passed and you've taken the proper default steps.

Phase 5 — The settlement conference (mandatory)

What happens: In most defended cases, the court schedules a settlement conference before trial. A judge or deputy judge meets with both sides — usually informally, sometimes virtually — to explore settlement, narrow the issues, and give a frank read on the strengths and weaknesses of each side. Many cases resolve here.

Who does it: Both parties (and their representatives, if any) and the judge or deputy judge.

What you need:

• Any documents the rules require you to file or bring (often copies of everything you intend to rely on at trial)
• A short, honest summary of your position and what you'd accept to settle
• An open mind — the judge's candid feedback is valuable, even when it's not what you hoped to hear

Why it matters: This is your cheapest off-ramp. It's also a preview: the questions the judge asks here often tell you exactly where your case is weak. Bring your settlement number and be ready to listen.

✅ You're done with this phase when the case settles, or the conference ends without settlement and the court sets next steps (often the path to trial).

Phase 6 — Prepare for trial

What happens: If you didn't settle, you build your case for trial. Small Claims trials are less formal than higher-court trials, but you still have to prove your case with evidence.

Who does it: You.

What you need:

• An organized set of documents — contracts, invoices, receipts, emails, texts, photos — ideally in a tidy, numbered, chronological bundle
• Your witnesses lined up (people with direct knowledge). If a witness won't attend voluntarily, ask the court about a summons to witness
• A clear damages calculation — the exact amount you're claiming and the proof behind each number
• A simple outline of the story you'll tell and the points you must establish

💡 Tip: Bring enough copies of every document — typically one for the judge, one for the other side, and one for yourself. (Treadstone's Evidence Organization Checklist walks through how to assemble all of this.)

✅ You're done with this phase when your evidence is organized, your witnesses are confirmed, and you can explain your claim and your numbers in plain language.

Phase 7 — The trial

What happens: Each side presents its case to a judge (there's no jury in Small Claims). You explain what happened, put in your documents, call your witnesses, and the other side does the same. The judge may ask questions. Everyone gets a chance to respond to the other's evidence.

Who does it: Both parties and the judge.

What to expect:

• It's a hearing, not a TV drama — be organized, respectful, and brief.
• Stick to facts the judge needs and the documents that prove them.
• Listen to the questions; answer them, not the question you wish you'd been asked.

✅ You're done with this phase when both sides have presented their evidence and made their final points, and the judge has heard the case.

Phase 8 — Judgment

What happens: The judge decides. Sometimes you get the decision right there ("orally"); sometimes the judge "reserves" and sends written reasons later. The judgment says who owes what, and may address interest and costs.

Who does it: The judge.

A note on costs: The winning side can sometimes recover certain costs and disbursements, but Small Claims costs awards are limited and the court has discretion. Don't expect a full reimbursement of your time and effort.

✅ You're done with this phase when you have the court's judgment in hand.

Phase 9 — Enforcement (getting actually paid)

What happens: A judgment is not a cheque. If the losing party doesn't pay voluntarily, you have to enforce the judgment — the court won't collect for you. Tools may include examining the debtor about their finances, garnishing wages or bank accounts, or seizing and selling property, each with its own forms and process.

Who does it: You (the judgment creditor), often with the court enforcement office.

⚠️ Watch out: This is where many self-represented people get stuck. Winning is one thing; collecting from someone with no money or assets (a "judgment-proof" debtor) is another. This is part of why Phase 0's reality check matters — see Treadstone's separate enforcement guide for the step-by-step on collecting.

✅ You're done with this phase when the judgment is paid (or you've exhausted reasonable enforcement options).

Mini-FAQ

Do I need a lawyer in Small Claims Court? No — the court is designed for self-representation. But for higher-value claims, tricky facts, or a defendant fighting hard, a lawyer or paralegal can sharpen your odds. Many people get advice at the start and at the settlement conference even if they run the rest themselves.

How long does the whole thing take? It varies a lot by location and how contested the case is — anywhere from a few months to well over a year. Court backlogs affect timing more than anything.

What if I'm the one being sued? The same roadmap runs in reverse. Read the claim carefully, note your deadline to file a Defence, and respond on time — missing it can lead to default judgment against you. Get advice early.

Can I appeal? Limited appeal rights exist, generally to a higher court and within strict time limits. If you're considering it, talk to a lawyer quickly — the window is short.
