How to prepare for
your trial.

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

By the time you have a trial date in Small Claims Court, the hard procedural part is mostly behind you. You filed the claim, the other side fought it, you went through a settlement conference and it did not resolve, and now you have a single day in front of a deputy judge to prove you are right. The question I get at this stage is always the same: "What do I actually do to get ready?"

Here is the truth I tell every client. Most Small Claims trials are decided by preparation, not by eloquence. The person who organized their documents, knew exactly what they had to prove, and could tell their story plainly almost always beats the person who showed up with a shoebox of receipts and a lot of feelings. The deputy judge has never met you and knows nothing about your dispute. Your whole job on trial day is to make a stranger understand what happened and why the law is on your side — quickly, calmly, and in order.

This guide is about trial-day preparation specifically. If you are earlier in the process and want the whole roadmap, read the steps to represent yourself in Small Claims Court and my guide on how to sue in Small Claims Court in Ontario. What follows assumes you are past all that and the trial is coming. Below is exactly how I prepare a case, step by step, and the mistakes I watch people make over and over.

What a Small Claims trial actually is — and why prep wins it

A trial is the formal hearing where a deputy judge listens to both sides, looks at the evidence, and decides who is right. It is not a conversation, and it is not the place to figure out your case for the first time. It is a structured event with a clear order, and the side that understands that order and prepares for it has an enormous advantage.

People imagine trials as dramatic, with clever arguments winning the day. Real Small Claims trials are far more mundane: someone tells a clear story backed by documents, and someone else tells a muddled one backed by half-remembered details. The deputy judge has limited time and a list of other matters that day. Clarity reads as credibility. The plaintiff who can say "here is what was agreed, here is the contract at tab 1, here is the invoice at tab 2, here is the proof I was never paid at tab 3" is doing the judge's job for them — and that is what preparation buys you.

That is why I say prep wins it. You cannot control what the deputy judge thinks, but you can control whether your case is easy to follow. Easy-to-follow cases win the close ones.

How early should I start preparing for trial?

Start the moment you have a trial date — not the week before. Good preparation is not a single evening of work; it is gathering documents, tracking down witnesses, and serving any summons in time, all of which have lead times you cannot compress. The people who scramble in the final days are the ones who discover, too late, that a key witness is unavailable or a crucial record was never kept. Give yourself weeks, not hours.

From my experience

From my experience, the gap between a prepared party and an unprepared one is bigger than any point of law. I once watched a self-represented plaintiff lose a case he should have won because he could not find the one email that proved his point — it was buried somewhere in his phone, and by the time he scrolled to it the moment had passed and the judge had moved on. His evidence existed. He just could not produce it when it mattered.

The flip side is just as common. I have seen people with thin cases do surprisingly well purely because they were organized, calm, and clear. They told their story in order, handed up tidy copies, answered the deputy judge's questions directly, and did not argue. The judge could follow them, and following you is the first step to believing you.

So when a client asks me what wins, I do not point to a slick argument. I point to the boring stuff: knowing your three or four key facts cold, having a document for each one, and being able to walk a stranger through it without notes you have to dig for. That is the work. Do it, and you have done more than most people who walk into that courtroom.

What the law and the process require

Before you prepare, you need to know the rules of the game you are walking into. Two things matter most: what you have to prove, and how the day will unfold.

Your burden is the balance of probabilities. In a civil case like this, you do not have to prove anything "beyond a reasonable doubt" — that is the criminal standard and it has nothing to do with Small Claims Court. You have to prove your case on the balance of probabilities, which simply means more likely than not. If the deputy judge thinks your version is even slightly more probable than the other side's, you have met your burden. And the party asserting a claim is the one who has to prove it, so as the plaintiff, that burden sits with you.

The trial follows a set order. The plaintiff goes first, presenting their evidence and calling their witnesses. Then the defendant presents their case. Throughout, the deputy judge can ask questions of anyone — they are not a silent referee. After the evidence is in, both sides make brief closing submissions tying the evidence to what had to be proven. The judge then gives a decision, sometimes right there and sometimes reserved for later. Most Small Claims trials are completed in a single day.

The rules of evidence are relaxed. This is one of the best features of Small Claims Court for a self-represented person. Under section 27 of the Courts of Justice Act, the court can admit any relevant oral testimony, document, or thing — including emails, text messages, and photographs — even if it would be excluded as hearsay in a higher court. Hearsay is still allowed, but the deputy judge gives it less weight than evidence a witness can speak to directly. Privileged material stays out, and copies of documents are admissible as long as the judge is satisfied they are authentic. In practice, this means you can bring in the texts and photos that tell your story.

Common situations I see

Over the years, most of the trials I prepare for fall into a few recognizable shapes, and each one calls for a slightly different emphasis.

The unpaid invoice or unpaid contract. The plaintiff did work or delivered goods and was not paid. These cases live and die on documents: the agreement, the invoice, proof the work was done, and proof of non-payment. If your documents are clean and in order, these are often the most winnable cases on the docket.

The "he said, she said" with no paper. A verbal deal, a handshake, a falling-out, and now two people remember it differently. Here your own testimony and any witness who was present become the whole case. Preparation means knowing your story cold and finding any contemporaneous text or email that supports it, even a small one.

The defendant who is being sued. If you are on the receiving end of a claim, your prep is a mirror image — you are looking for the gaps in what the plaintiff has to prove and the evidence that contradicts their story. I cover that side specifically in what to do when someone is suing you in Small Claims Court, and if you want representation, a Small Claims Court defence lawyer in Toronto can help you build it.

The strong case prepared badly. The most frustrating one. The facts are on your side, but your evidence is a mess, you ramble, and you let your emotions run the show. These are the cases that should be easy wins and turn into losses purely on presentation.

What if my whole case is just my word against theirs?

It happens constantly, and it is not fatal. When there is no paper, your credibility becomes the evidence. The deputy judge decides who to believe by looking at consistency, plausibility, and whether your version fits the few facts that are not in dispute. Tell a clear, consistent story, do not exaggerate, and hunt for any small contemporaneous record — a single text, an email, a calendar entry — that corroborates even one piece of your account. A little corroboration goes a long way in a he-said-she-said.

The step-by-step trial prep

This is the core of it. Here is exactly how I prepare a Small Claims case for trial, in the order I do it. Work through these steps and you will walk in more prepared than the large majority of people who appear in that courtroom.

1. Know exactly what you must prove

Everything starts here. Before you touch a document, write down — in one or two sentences — what you have to establish to win, on the balance of probabilities. Break your claim into its elements. For an unpaid invoice, that usually means: a deal existed, you performed your end, and you were not paid the amount owed. For a damaged-property claim: the defendant caused the damage, and it cost you a specific amount to fix.

Once you have your list of elements, every piece of evidence either supports one of them or it is clutter. This single exercise organizes your whole case and exposes your weak spots. If you cannot point to a document or a witness for one of your elements, that is the hole the other side will drive through, and you want to find it now, not on the stand.

2. Organize your documents in order

Put your documents in chronological order — the order events happened — so the story tells itself as you flip through. A contract, then the invoice, then the emails chasing payment, then the photos of the finished work. Number or tab the pages so you can say "the email at tab 4" and everyone turns to the same page instantly.

Then make three copies of everything: one for the deputy judge, one for the other side, and one for yourself to hold while you speak. Each set must be identical and in the same order. Bring your originals too, in case the court wants to see them — copies are admissible if the judge is satisfied they are authentic, but having the originals available removes any doubt. For more on what actually persuades a court, see what evidence wins in Small Claims Court.

3. Prepare your own testimony

You are almost certainly your own most important witness. Prepare to tell your story plainly, in chronological order, from the beginning. Do not start with how outraged you are or how the other side behaved — start with the facts in sequence: what was agreed, what happened, what went wrong, what you are owed.

Write out your story as a timeline and practise telling it out loud, pointing to your documents as you go ("we signed the contract on the 3rd — that is tab 1"). Keep it to the facts. Resist the urge to argue or characterize; the deputy judge will draw the conclusions. Your job is to be the clear, credible narrator of what happened. If you can tell your story in five minutes without notes you have to dig for, you are ready.

4. Line up your witnesses — and summons them if needed

If someone other than you saw or did something that helps prove an element of your case, you want them in the room. Talk to them ahead of time so you know what they will say, and make sure their evidence actually helps — a witness who waffles can hurt you.

If there is any chance a witness will not show up voluntarily — or if they need a formal reason to take time off work — serve them with a summons to witness (Form 18A), along with the required attendance (conduct) money to cover their travel. A summons is a court order compelling the person to attend and give evidence. File and serve it in time under the Rules and keep your proof of service. In my experience the witness who casually promised to come is exactly the one who does not, so when their evidence genuinely matters, summons them rather than hope.

5. Prepare your questions for the other side

When the defendant or their witnesses testify, you get to ask them questions — this is cross-examination. The goal is not to argue or make a speech; it is to pull out admissions that help you or expose inconsistencies in their story. Write your questions in advance, keep them short and pointed, and ask one fact at a time.

Good cross-examination questions are closed, not open. You ask "you received my invoice on March 1, correct?" not "tell me about the invoice." You already know the answer you are looking for; you are just getting it on the record. Resist the temptation to cross-examine on everything — pick the two or three points that matter and leave the rest alone.

6. Prepare a short, focused closing

At the end, you get to sum up. This is where you finally connect the dots out loud: here is what I had to prove, here is the evidence that proves each part, therefore I have met my burden on the balance of probabilities. Keep it short. A focused two- or three-minute closing that ties evidence to elements beats a rambling ten-minute one every time.

Write your closing as a simple list mirroring your elements from step one. By trial day the deputy judge has heard everything; your closing just hands them a clean path to ruling in your favour.

7. Handle the logistics

None of the above matters if you are late or in the wrong place. Confirm the courthouse location and your start time well in advance, and plan to arrive early — security lines and finding the right courtroom take time. Bring your three sets of documents, your originals, a pen and paper for notes, and a printed copy of your own timeline and questions.

Dress as though the day matters, silence your phone before you go in, and give yourself a buffer. Small logistical failures — a missed copy, a witness who could not park, arriving flustered — undo hours of good preparation. Treat the logistics as part of the case, because they are.

The evidence to bring to trial

Because Small Claims Court has relaxed rules of evidence, you can bring far more than people assume. The point is not to bring everything — it is to bring the right things, organized so the deputy judge can use them. Here is what I make sure is in the file.

• The core documents. The contract or agreement, the invoices, receipts, quotes, and any signed paperwork. These are the backbone of most cases.
• The correspondence. Emails and letters between you and the other side, in date order. A clean email trail often tells the whole story on its own.
• Text messages. Printed as a readable thread showing who sent what and when. Texts are admissible and frequently decisive — I cover this in detail in whether text messages can be used as evidence in Small Claims Court.
• Photographs. Labelled with what they show and the date taken. Photos of damage, finished or unfinished work, or goods delivered can settle a factual dispute instantly.
• Proof of payment or non-payment. Bank records, e-transfer confirmations, or a statement showing what was and was not paid.
• Anything that proves an element. Go back to your list from step one. For every element you must prove, you should be able to point to at least one item in this file.

Common trial mistakes

The same handful of mistakes sink self-represented people over and over, and the painful thing is that every one of them is avoidable with preparation. Here are the ones I see most.

Disorganized documents. Fumbling for the right page while the deputy judge waits is the most common unforced error. It wastes time, reads as unprepared, and means your best evidence sometimes never gets seen. Chronological order and tabs fix this entirely.

Rambling. Telling the story out of order, circling back, piling on irrelevant detail. The judge has limited time and a docket to get through. If they cannot follow you, they cannot rule for you. Tell it once, in order, and stop.

Getting emotional. These disputes are personal, and the feelings are real. But the moment you get angry or tearful, the focus shifts from your evidence to your composure. State the facts calmly and let them carry the weight. Emotion is not evidence.

No copies. Showing up with a single file and nothing to hand up forces the court to share or adjourn, and it signals you did not prepare. Three sets, every time.

Arguing with the judge. When the deputy judge questions you or rules against you on a small point, the worst thing you can do is push back or talk over them. Answer the question, accept the ruling, and move on. For a fuller list, I have a whole piece on the common mistakes that make people lose in Small Claims Court.

What happens in court — and how to conduct yourself

Knowing how the room works removes a lot of the anxiety, and it keeps you from making the conduct mistakes that quietly cost people their cases.

When your matter is called, you will be in front of a deputy judge — that is who hears Small Claims trials. Address them as "Your Honour." Stand when you speak if you are able, and speak to the judge, not to the other side. The plaintiff presents first, then the defendant, and the deputy judge may interject with questions at any point; answer them directly and honestly, even when the answer is not helpful to you.

Do not interrupt. Not the judge, not the other side, not their witnesses. When it is not your turn, write down what you want to respond to and raise it when you have the floor. When you question the other side, stay calm and ask one fact at a time. Throughout, keep your tone even. The deputy judge is assessing credibility as much as evidence, and a calm, respectful, organized party simply comes across as more believable than a combative one. Respect for the process is not just etiquette — it is strategy.

Settlement is still on the table

Here is something people forget once they have a trial date: you can still settle, right up to and even during the trial. A trial is a roll of the dice decided by a stranger in a single day. A settlement is an outcome you control. If a fair deal is available, taking it is often the smarter move than gambling on a win.

I tell clients to keep the door open. Sometimes the other side, faced with the reality of an actual trial, becomes far more reasonable in the hallway than they ever were at the settlement conference. Your trial preparation is not wasted if you settle — it is the very thing that gives you leverage. A party who is visibly ready for trial negotiates from strength. Prepare to win, and stay open to a deal that lets you skip the risk.

Key takeaways

• Know what you must prove. Break your claim into its elements and make sure you have a document or a witness for each one — your burden is the balance of probabilities, not certainty.
• Organize and copy your evidence. Documents in chronological order, tabbed, with three identical copies: one for the deputy judge, one for the other side, one for you.
• Prepare your story and your witnesses. Practise telling it plainly in order, and serve a summons to witness (Form 18A) on anyone whose attendance you cannot count on.
• Stay calm and respectful. Address the deputy judge as "Your Honour," do not interrupt, do not argue, and let your evidence — not your emotions — carry the case.
• Settlement is still an option. You can resolve the case before or even at trial, and being well prepared is exactly what gives you the leverage to do it on good terms.

Frequently asked questions

How do I prepare for a Small Claims Court trial in Ontario?

Start by writing down exactly what you have to prove, because that tells you which evidence matters. Then organize your documents in date order, make three copies of everything (one for the deputy judge, one for the other side, one for you), and write out the story you will tell in plain order. Line up your witnesses and, if anyone might not show, serve a summons to witness. Draft a few short questions for the other side and a tight closing. In my experience, the prepared party wins cases the unprepared party should have won.

What do I need to prove at a Small Claims Court trial?

You prove your case on the balance of probabilities — more likely than not, just over 50 percent. You do not need certainty or proof "beyond a reasonable doubt"; that is the criminal standard and it does not apply here. The party asserting a claim has to prove it, so as the plaintiff you carry that burden. Break your claim into its elements — for an unpaid invoice, that a deal existed, you did the work, and you were not paid — and make sure you have a document or a witness for each one. Anything you cannot back up is a gap the other side will use.

How many copies of my documents do I bring to a Small Claims trial?

Bring three copies of every document: one for the deputy judge, one for the other side, and one for yourself to refer to while you speak. I see self-represented people show up with a single dog-eared file and nothing to hand up, and it makes a bad impression before they say a word. Put each set in the same order, paginated or tabbed the same way, so when you say "the contract at tab 3," everyone is looking at the same page. Copies are admissible if the deputy judge is satisfied they are authentic, so keep your originals in case the court wants to see them.

How do I bring a witness to a Small Claims trial, and what is a summons to witness?

If someone saw or did something that helps prove your case, you want them in the room. A witness can simply agree to attend, but if you have any doubt they will show up — or if their employer needs a formal reason to release them — you serve a summons to witness (Form 18A), along with the required attendance (conduct) money to cover their travel. A summons is a court order compelling the person to attend and give evidence. Serve it in time under the Rules and keep proof of service. In my experience the witness who "promised" to come is exactly the one who does not, so when their evidence matters, summons them.

Can I bring text messages and photos to a Small Claims Court trial?

Yes. Small Claims Court has relaxed rules of evidence under section 27 of the Courts of Justice Act — the court can admit any relevant oral testimony, document, or thing, including emails, text messages, and photos. Print your texts as a clean, readable thread showing who sent what and when, and label your photos with what they show and the date. Even hearsay can come in, though the deputy judge gives it less weight than something a witness can speak to directly. Privileged material stays out. The relaxed rules are a real advantage for self-represented people, so use them.

What do I actually say at a Small Claims Court trial?

You tell your story, plainly and in order. As the plaintiff you go first: you explain what happened, from the beginning, and point the deputy judge to the documents as you go. Do not argue, do not editorialize, and do not start with how the other side wronged you — start with the facts in sequence. Then you call any witnesses, the other side gets their turn, and at the end you give a short closing tying the evidence to what you had to prove. Think narrative, not argument. The judge wants to understand what happened; your job is to make that easy.

How should I behave at trial and how do I address the judge?

In Small Claims Court the judge is a deputy judge, and you address them as "Your Honour." Stand when you speak if you are able, do not interrupt — not the judge, not the other side, not their witnesses — and keep your tone even no matter how wrong you think the other side is. The fastest way to hurt your own case is to argue with the deputy judge or talk over someone. When it is not your turn, write down what you want to respond to and raise it when you get the floor. Calm, organized, and respectful beats loud and emotional every single time.

How long does a Small Claims Court trial take in Ontario?

Most Small Claims trials are completed in a single day, because the procedure is streamlined and the disputes are relatively contained. A straightforward matter can be done in a morning; a more involved one with several witnesses can fill the day. The deputy judge sometimes gives a decision right at the end and sometimes reserves it, meaning they take time to consider and release reasons later. The long part of a Small Claims case was never the trial itself — it was the months of waiting to get a trial date. Once you are in the room, it usually moves quickly.

What happens if I lose at a Small Claims Court trial?

If you lose, the deputy judge dismisses your claim, and you may be ordered to pay the other side some of their costs — though those costs are generally capped at 15 percent of the amount claimed under rule 19.04, except in unusual circumstances. You may have a right to appeal a final order to the Divisional Court, but only in limited situations and within a tight deadline, and an appeal is a serious step. This is exactly why settlement is worth taking seriously before trial: a negotiated outcome you can live with is often better than rolling the dice on a single day in court.

Should I hire a lawyer or paralegal for a Small Claims Court trial?

You can represent yourself, and many people do well — the court is built for it. But the value of representation goes up as the stakes and the complexity rise. If the amount is significant, the facts are contested, or the other side has a lawyer or paralegal, getting advice (even just to prepare) can change the result. In Ontario, both lawyers and licensed paralegals can represent you in Small Claims Court. At a minimum, a consultation can pressure-test your evidence and tell you honestly whether your case is as strong as you think it is before you spend a day in court.

Final thoughts

Preparing for a Small Claims trial is not about being a great public speaker or knowing legal jargon. It is about doing the unglamorous work: figuring out exactly what you have to prove, gathering the evidence that proves it, organizing it so a stranger can follow along, and being able to tell your story calmly and in order. That is the whole game, and it is entirely within your control.

The court is built for self-represented people, and many do well on their own. But the value of advice rises with the stakes and the complexity. If the amount matters to you, the facts are genuinely contested, or the other side has representation, getting a Toronto Small Claims Court lawyer or a paralegal to pressure-test your case before trial — or to run it for you — can change the outcome. Either way, the difference between winning and losing is usually made in the days before the trial, not in the courtroom itself.
