Preparing for Your Ontario Small Claims Court Trial: A Step-by-Step Guide

You filed your claim, survived the settlement conference, and now a trial date is on the calendar. For many self-represented litigants, that notice in the mail triggers pure panic. The good news: Ontario Small Claims Court is designed to be accessible. The less-good news: "accessible" does not mean "informal." Deputy judges apply the rules of evidence, take procedure seriously, and expect you to come prepared.

This guide walks you through every stage of preparation — from organizing your documents to what to say when you stand up on trial day.

As of writing, the Small Claims Court monetary limit is $35,000 (excluding costs and interest). Verify current limits at ontario.ca before filing.

How a Small Claims Trial Actually Runs

Understanding the flow prevents surprises. A typical trial follows this sequence:

1. Opening statements — Each side briefly tells the deputy judge what the case is about and what they intend to prove. Keep it under two minutes; this is a roadmap, not your full argument.
2. Plaintiff's case — The plaintiff calls witnesses (usually themselves first), introduces documents, and asks questions to establish each element of the claim.
3. Defendant's case — The defendant calls their own witnesses and introduces their evidence after the plaintiff closes.
4. Closing submissions — Each side summarizes the evidence and explains why the law and facts favour them. This is your chance to highlight contradictions in the other side's story.
5. Decision — The deputy judge may give an oral decision on the spot or reserve and send a written decision by mail.

The plaintiff always goes first because they carry the burden of proof. If you are the defendant, you do not have to prove you are right — you have to raise enough doubt about the plaintiff's story.

Building Your Trial Record (Document Book)

Bring three identical, tabbed copies of every document you plan to rely on: one for the deputy judge, one for the opposing party, and one for yourself.

What to include

• Your claim or defence (as filed)
• The minutes from any settlement conference
• Contracts, invoices, receipts, estimates, and written quotes
• Photos and screenshots (print them clearly; label each with a date and brief description)
• Text messages and emails (print the full thread, including headers that show sender, recipient, and date)
• Any expert or inspection reports

How to organize it

Number every page in the bottom-right corner. Create a one-page index at the front listing tab number, document title, and date. When you refer to a document during testimony, say "Tab 3 of my document book" — the deputy judge will follow along. Loose, unlabelled papers confuse everyone and undermine your credibility.

Subpoenaing Witnesses: The Summons to Witness

If a witness is reluctant to attend, you can compel their attendance using a Summons to Witness (Form 18A under the Rules of the Small Claims Court). File the form at the court office, pay the required fee, and arrange personal service on the witness well in advance of the trial date.

A few practical points:

• Serve the summons early — last-minute service can give the witness grounds to object or request an adjournment.
• You must tender conduct money (a payment to cover the witness's travel and attendance costs) at the time of service. Check the current prescribed amount with the court office.
• A witness who ignores a properly served summons can be held in contempt.

If your only witness is yourself, no summons is needed — but think carefully about whether someone else saw or heard something important. An independent corroborating witness can make or break a credibility dispute.

Questioning Witnesses: Examination in Chief vs. Cross-Examination

Examination in chief (your own witnesses)

You cannot ask leading questions (questions that suggest the answer) when examining your own witnesses. Ask open-ended questions: "What happened next?" "What did you see?" "Can you describe the condition of the property?" Let the witness tell the story in their own words.

Cross-examination (the other side's witnesses)

You may — and should — lead on cross. "It is true, isn't it, that you never provided a written quote?" Keep it controlled: stick to facts you can contradict with your documents. Do not argue with the witness; ask short questions and sit down when you have what you need. Long, rambling cross-examinations rarely help.

Hearsay caution

Testimony about what a third party told the witness is generally hearsay and may be objected to. If a document or statement from someone who is not testifying is important, get that person to court.

What the Deputy Judge Is Watching For

Deputy judges are experienced lawyers sitting as adjudicators. They are assessing:

• Credibility — Does your story hold together? Are you consistent? Do your documents back up what you say?
• Corroboration — Independent evidence (photos, texts, a second witness) carries far more weight than your word against theirs.
• Damages — Even if you prove liability, you must also prove the dollar amount you lost. Bring receipts, quotes, and bank records.
• Mitigation — In most civil claims you are required to take reasonable steps to limit your loss. If you sat on a problem for six months when you could have fixed it for $200, expect questions about that.

Courtroom Etiquette

• Arrive at least 30 minutes early. Find your courtroom, check in with the clerk, and confirm your matter is still on.
• Stand when the deputy judge enters and exits.
• Address the deputy judge as "Your Honour."
• Do not interrupt the other party or their witnesses — note the point and address it in cross or closing.
• Turn your phone off completely.
• Speak slowly and clearly. The deputy judge may be taking notes.

Trial Day Checklist

Use this the night before and again the morning of:

• [ ] Three sets of tabbed, indexed document books packed
• [ ] Original documents brought (in case originals are requested)
• [ ] Witness summonses confirmed and witnesses reminded of the time and location
• [ ] Printed copy of your filed claim or defence
• [ ] Settlement conference minutes included
• [ ] Notes for your opening statement (two minutes maximum)
• [ ] List of questions for each witness — examination in chief and cross
• [ ] Outline for closing submissions
• [ ] Photo ID
• [ ] Pen and notepad for taking notes during the other side's testimony
• [ ] Phone silenced

Common Mistakes Self-Represented Litigants Make

1. Confusing narrative with evidence. Telling the deputy judge what happened is not enough — you must prove it with documents or corroborating witnesses.

2. Missing the limitation period. As of writing, Ontario's basic limitation period is two years from the date you knew or ought to have known about the claim. A claim filed too late will be dismissed. Verify the deadline for your specific claim type.

3. Over-claiming. Claiming more than you can document creates credibility problems for your entire case. Claim what you can prove.

4. Ambushing with new documents. Evidence you did not disclose before trial may be excluded. Exchange your document list with the other side in advance and follow any pre-trial disclosure directions from the settlement conference.

5. Losing composure. The deputy judge is not on your side or theirs. Emotional outbursts, personal attacks on the opposing party, and visible frustration all hurt your credibility. Stay calm and focused on the facts.
