How to Prepare for a Small Claims Court Trial in Ontario

Reaching trial means your case didn't settle — but it doesn't mean you're on your own without a plan. A Small Claims Court trial is simpler and less formal than what you might picture from television, and thorough preparation matters more than legal training. Most people who prepare well can present their case clearly without a lawyer — see self-represented litigant tips for general habits that help throughout the process, not just on trial day.

What a Small Claims Court trial actually looks like

A Small Claims Court trial is generally shorter and more informal than a Superior Court trial. A deputy judge hears both sides, looks at the evidence presented, and makes a decision — often the same day or shortly after. There's no jury. The plaintiff generally presents their case first, followed by the defendant, with each side able to ask questions of the other's witnesses.

Because the process is streamlined, being organized matters even more — you typically won't get an extended opportunity to introduce something you forgot to bring. Think of trial as the moment where all your earlier preparation — the claim or defence you filed, the evidence you've gathered, and what you learned at the settlement conference — finally gets presented in one focused sitting.

Organize your evidence

Pull together everything that supports your case, and organize it so you (and the judge) can find any specific document quickly.

• Contracts and agreements, including any amendments or related correspondence.
• Invoices, receipts, and proof of payment.
• Communications — emails, texts, letters — especially anything that supports your account or contradicts the other side's.
• Photos or inspection reports, printed or otherwise easy to display.
• A timeline of events, so you (and the judge) can follow the sequence clearly.

Make at least three copies of everything: one for you, one for the other side, and one for the judge, unless you're told otherwise. Number or label your documents so you can refer to "Exhibit 3" rather than shuffling through a stack mid-sentence. Put them in a binder or folder in the order you plan to refer to them, rather than a loose pile — a small investment of time that makes a real difference under pressure.

Prepare your witnesses

If anyone else saw or knows something relevant firsthand, consider whether they should testify. Contact them well in advance to confirm they can attend, walk them through what they'll likely be asked, and be honest with them about what to expect — including that the other side may ask them questions too.

Prepare a short list of questions for each witness that draws out the specific facts they know, in a logical order. Avoid leading them through a script — a witness who sounds rehearsed is often less persuasive than one who answers naturally.

Build a clear, simple narrative

Judges hear many cases. The clearest, most organized presentation tends to land best — not the most dramatic one. Prepare a short opening statement: what happened, what you're asking for, and the two or three key pieces of evidence that support it. Practice saying it out loud so it doesn't come out disorganized under nerves.

Structure your account chronologically where possible — it's the easiest structure for anyone unfamiliar with your situation to follow. A simple, effective structure looks like: what the agreement or situation was, what went wrong and when, what you did in response (like sending a demand letter), and what you're asking the court to order now. Each part should connect directly to a specific piece of evidence you'll show.

Anticipate the other side's case

Read the claim or defence filed against you carefully, and think through how you'd respond to each specific point. If you were the one who filed a Defence, revisit it — the other side has had time to think about how to respond to it, and so should you.

Ask yourself honestly: what's the strongest argument against my position? Prepare a clear answer for it rather than hoping it doesn't come up.

Asking questions of the other side's witnesses

After the other side's witnesses testify, you'll generally have a chance to ask them questions. This isn't about scoring points or being aggressive — it's about testing whether their account holds up and drawing out anything that supports your case.

• Prepare specific questions in advance based on what you expect them to say, rather than improvising entirely on the spot.
• Ask short, direct questions rather than long ones that give a witness room to avoid the actual point.
• Stay calm and factual — a hostile tone tends to undermine your credibility more than theirs.
• Know when to stop. Once a witness has confirmed the point you needed, move on rather than continuing to press and risking an answer that undoes your progress.

Presenting documents and exhibits

When you refer to a document, identify it clearly ("this is the invoice dated March 3, which I've marked as Exhibit 2") before explaining what it shows. Hand copies to the judge and the other side at the appropriate point rather than all at once at the start, unless instructed otherwise. If you have physical evidence too large or awkward to hand over (like a damaged item), photographs are usually a practical substitute — bring both if you can.

If the other side doesn't show up

Occasionally, one side doesn't appear for trial. If that happens, the case doesn't necessarily stop — the court may proceed based on the evidence of whoever is present, which is one more reason to have your own case fully organized and ready regardless of what you expect the other side to do.

What to expect from the deputy judge

The deputy judge's role is to listen to both sides, ask clarifying questions, and reach a decision based on the evidence and the law. They may ask you direct questions about your claim or your evidence — treat these as an opportunity to clarify, not as a sign you've done something wrong. Answer directly and stick to what you actually know firsthand.

Trial day checklist

• Arrive early to account for finding the courtroom, security, and any last-minute paperwork.
• Bring multiple copies of every document you plan to use.
• Bring your opening statement notes, but don't read them word for word.
• Bring a notepad to jot down points raised by the other side that you want to respond to.
• Confirm your witnesses know the time and place, and have a backup way to reach them that morning.
• Dress and behave formally, even though the setting is less formal than you might expect.

Common mistakes to avoid

• Showing up without organized documents, then struggling to find what you need mid-testimony.
• Rambling instead of answering the question asked.
• Arguing with the judge or the other side instead of calmly making your point once, clearly.
• Bringing witnesses who weren't prepared for what to expect.
• Failing to anticipate the obvious counterargument to your case.
• Focusing on how the other side behaved rather than the facts that actually matter to the claim.
