Can you sue anyone
for anything?

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

“Can I sue anyone for anything in Small Claims Court?” is one of the most common questions I hear, usually from someone who has just been wronged and wants to know whether the court can help. The instinct behind it is understandable: people imagine Small Claims Court as a kind of general complaints department where, if something is unfair, a judge will set it right.

The reality is more specific — and, once you understand it, more useful. Ontario’s Small Claims Court can resolve a huge range of everyday disputes, fast and affordably. But it is a court of limited jurisdiction. There is a dollar ceiling on what it can award, a short list of remedies it can actually give, and certain disputes that belong somewhere else entirely. So “anyone for anything” is the right starting point — as long as you understand the boundaries.

In this guide I’ll walk through what you can and can’t sue for, who you can effectively sue, the $50,000 limit, the deadlines that quietly kill good claims, and the mistakes I see people make over and over. The goal is to help you decide, before you spend a dollar on a filing fee, whether Small Claims Court is the right tool for your problem.

Understanding the question

Here is the honest short answer: in Ontario, you can sue for almost any money claim up to $50,000 in Small Claims Court — but you cannot literally sue “anyone for anything.” Two words in that phrase carry real limits.

The “anything” is constrained by what the court can do. Small Claims Court hears claims for money or the return of personal property valued up to $50,000 (not counting interest and costs). It generally cannot order someone to behave a certain way, force a deal to go through, or decide who owns a piece of land. You also need a real legal basis — a contract that was broken, a debt that went unpaid, property that was damaged or wrongfully kept. “It’s not fair” is not a cause of action.

The “anyone” is constrained by who you can practically sue and collect from. You can sue individuals, corporations, and sole proprietors — but only if you name the right legal entity, they have some connection to Ontario, and (the part most people forget) they actually have the means to pay if you win. A judgment against someone with nothing is, as I often tell clients, an expensive piece of paper.

From my experience

From my experience, what surprises people most is the gap between “I have a legitimate grievance” and “this is a claim a court can do something about.” Over the years I’ve had people come in genuinely shocked that they can sue — a friend who never paid back a $9,000 loan, a contractor who took a deposit and vanished, a buyer who paid for a dining set online that never arrived. They assumed informal deals weren’t enforceable, or that without a signed contract they had no case. In all three, they had a perfectly good claim.

And then there’s the other direction — people surprised by what they can’t do. Someone wants the judge to order a neighbour to stop doing something annoying; that’s an injunction, and Small Claims Court can’t grant it. A residential tenant wants to sue their landlord over the rental unit; most of those disputes belong at the Landlord and Tenant Board, not here. And more than once, someone has wanted to sue purely to be vindicated — to have a judge declare the other person a liar. The court awards money for proven losses. It does not hand out apologies, and it will not spend a trial day deciding who was the better person.

The lesson I’ve drawn over the years is simple: Small Claims Court is powerful precisely because it is focused. Knowing what it’s for — and what it isn’t — is half the battle. The people who do well are the ones who walk in with a quantifiable loss and the paper to prove it, not the ones nursing a grievance they hope a judge will simply agree with.

What the law generally says

Let’s get concrete about the rules that define the court’s reach.

The $50,000 monetary limit

The single most important number is $50,000 — the maximum a claim can be worth, excluding interest and costs. That cap defines the court’s monetary jurisdiction. You can sue for anything from a few hundred dollars up to that ceiling. If your real loss is larger, you have to either abandon the excess to stay here, or take the whole thing to the Superior Court of Justice. I cover the cap in detail in the Ontario Small Claims Court $50,000 limit.

Money or the return of property — and not much else

Small Claims Court hears claims for money or the return of personal property valued up to $50,000. That is the core of what it does. It generally cannot grant injunctions, order specific performance beyond returning personal property, or decide title to land. If the remedy you need is anything other than a money award or getting a specific item back, you are probably in the wrong court.

Who and where you can sue

You can sue a person, a corporation, or a sole proprietor — provided you name them correctly and the court has a connection to the dispute. Generally that means the defendant lives or carries on business in Ontario, the agreement was made or to be performed here, or the events happened here. You also have to sue in the right court location, which is normally tied to where the defendant lives or carries on business, or where the events giving rise to the claim took place. File in the wrong location and you can face a transfer or, worse, a defendant who objects and slows everything down. For a primer on the right venue, see when to use Small Claims Court in Ontario.

The limitation period

You do not have forever. Under the Limitations Act, 2002, you generally have two years from when you discovered (or reasonably should have discovered) the claim to start it (ss. 4–5), with an ultimate limit of 15 years (s. 15). Miss the deadline and the defendant can raise a complete limitations defence — meaning even a strong claim gets dismissed. Discoverability, acknowledgments, and partial payments can shift the clock, so when in doubt, check where you stand with the limitation period calculator.

What’s excluded

Finally, some matters are carved out and sent elsewhere by statute — residential landlord-and-tenant disputes to the Landlord and Tenant Board, for example, and family and estate matters to their own courts. More on those below. Ontario publishes its own guide to Small Claims Court procedures if you want the official overview.

Common situations I see

In practice, the same kinds of disputes come through my door again and again, and the vast majority of them fit comfortably inside Small Claims Court. Here are the ones I see most.

Unpaid invoices

A client or customer received your goods or services and never paid. This is the classic Small Claims case. The invoice, proof of delivery or completion, and any emails or texts confirming the work are usually enough. These are often the cleanest claims to win. If this is you, see unpaid invoice and loan recovery.

Loans to friends and family

You lent money to someone you trusted and never got it back. Perfectly suable. The challenge is proving it was a loan and not a gift — an e-transfer record, a text promising repayment, or a partial repayment goes a long way.

Contractor disputes

A renovator did defective or incomplete work, or took a deposit and disappeared. Photographs, the contract or quote, and estimates to fix the problem make these strong claims. They are squarely within Small Claims Court’s wheelhouse.

Property damage

Someone damaged your car, your fence, or your belongings and won’t cover the cost. As long as you can prove the damage and its value with photos, repair invoices, or quotes, you can sue for it.

Returned-deposit and security-deposit fights

A deposit you paid was not returned when the deal fell through, or a deposit you are owed is being wrongfully withheld. (Note: residential rent and tenancy issues usually go to the Landlord and Tenant Board — see below — but plenty of deposit disputes outside the residential-tenancy context belong in Small Claims.)

Online sales gone wrong

You paid for something through an online marketplace and received the wrong item, a broken one, or nothing at all. These cases have exploded in recent years, and they are exactly the kind of straightforward money claim the court handles well — assuming you can identify and locate the seller.

What ties all of these together is a recognizable legal wrong — usually a broken contract or an unpaid debt — and a quantifiable dollar loss. If you can put both of those on paper, you almost certainly have a claim. For the mechanics of actually filing one, see how to sue in Small Claims Court in Ontario.

Who you can — and can’t — effectively sue

“Can I sue them?” really has two parts: can I legally sue this person or business, and will it actually get me anywhere. Both matter, and the second one gets ignored far too often.

Naming the right defendant

This is, hands down, the most common technical mistake I see. You have to sue the correct legal entity, named exactly.

• People. An individual is sued by their full legal name. Simple enough.
• Corporations. If the business is incorporated, you sue the corporation by its exact registered name — “ABC Plumbing Ltd.” or “1234567 Ontario Inc.” — not the trade name on the truck and not the owner personally. A corporation is its own legal person, separate from the human who runs it.
• Sole proprietors. If the business is not incorporated, there is no separate company to sue — you sue the individual owner, who can be named as carrying on business under the trade name.

How do you find out which one you’re dealing with? A business-name or corporate search (through ServiceOntario or a corporate-profile report) tells you the true legal entity before you file. Spend the small fee. Suing the wrong name — the trade name instead of the corporation, or the owner instead of the company — can hand the other side a defence and waste your filing fee.

What if the company has been dissolved?

Sometimes you go to sue a corporation and discover it has been dissolved. That doesn’t always end things — in some cases the corporation can be revived so it can be sued, and in certain situations a director may be personally responsible for specific obligations. It’s technical and fact-specific, so get advice rather than assuming the debt simply vanished with the company.

The judgment-proof defendant

Now the part people skip. Before you sue, ask yourself the real question: if I win, can this person actually pay? Do they have a job, a bank account, a business, or property? If the honest answer is no across the board, you may be chasing a defendant who is “judgment-proof” — someone a judgment cannot reach because there is nothing to collect. Winning feels good for an afternoon; an uncollectable judgment helps no one. This single question should shape whether you sue at all. A practical tip: do a little homework before you file. Is the defendant employed somewhere stable? Do they own their home? Is the business still operating and paying suppliers? You won’t always be able to tell, but even a rough read on whether there are assets behind the defendant can save you from spending good money chasing nothing.

Suing across borders

You can usually only sue in Ontario where there is a genuine connection to the province. Trying to sue someone in another province or country is harder: the court needs jurisdiction, you have to serve the defendant wherever they are, and — even if you win — enforcing an Ontario judgment against assets elsewhere is a project of its own. Within Canada, reciprocal-enforcement rules sometimes help. Internationally, Small Claims Court is rarely the right vehicle. If your dispute crosses a border, talk to a lawyer before you spend anything.

What you can’t get in Small Claims Court

This is where “anything” runs into hard walls. There are entire categories of relief Small Claims Court simply cannot give, no matter how strong your case.

No injunctions or specific performance (beyond returning property). The court cannot order someone to do something or stop doing something. It cannot force a seller to go through with a sale, force a contractor to come back and finish, or stop a person from continuing some conduct. The one narrow exception is ordering the return of a specific item of personal property. Everything else in this family — injunctions, declarations, specific performance — lives in the Superior Court.

No claims about title to land. Disputes over who owns real estate, boundary disputes, and similar land-title questions are outside Small Claims Court’s authority. The court deals in money and movable property, not real property ownership.

Matters that belong to another forum. The legislature has assigned some disputes elsewhere. The big one for everyday life is residential landlord-and-tenant disputes, which generally go to the Landlord and Tenant Board, not Small Claims Court. Family law and estate matters have their own courts and tribunals as well. Filing one of these in Small Claims Court just costs you a filing fee and a dismissal.

The $50,000 cap and “abandoning the excess.” And of course, money claims over $50,000. If your loss is, say, $65,000, you can’t sue for the full amount here. You can abandon the excess — formally give up the $15,000 over the cap and proceed for $50,000 — or take the whole claim to the Superior Court. Abandoning is permanent; you can’t come back for the rest later, and you can’t split one claim into two cases to slip under the limit. If you’re weighing the two courts, read Small Claims Court vs. Superior Court in Ontario.

Can I sue my landlord in Small Claims Court?

It depends on the dispute. If it’s a residential tenancy issue — rent, repairs, eviction, a last-month deposit — that almost always belongs at the Landlord and Tenant Board, which has exclusive authority over most of those matters. Where Small Claims can come in is a money claim that falls outside the Board’s jurisdiction, or certain disputes once a tenancy has ended. Because the line can be subtle, it’s worth confirming which forum applies before you file, so you don’t lose time and a filing fee at the wrong door.

Groundwork to gather before you sue

The cases that go smoothly are the ones where the plaintiff did their homework before filing. Whatever your claim, pull together your evidence first.

• Contracts and agreements. Any written contract, quote, signed estimate, or terms you agreed to — even an email exchange that sets out the deal.
• Invoices and financial records. Invoices, receipts, e-transfer confirmations, bank records, and anything showing money changed hands or is owed.
• Messages. Texts, emails, and chat messages — especially anything where the other side acknowledges the debt, promises to pay, or admits fault.
• Proof of loss. Photographs of damage or defective work, repair quotes, and documents that establish the dollar value of what you lost.
• Proof of who the defendant really is. A business-name or corporate search confirming the exact legal entity and a current address for service.

You don’t need a signed contract to sue — verbal agreements are enforceable in Ontario, and this comes up constantly in unpaid-work and loan cases. But you do need something beyond your own word. The more of the above you can assemble, the stronger your position. To understand why a real legal basis matters, see what breach of contract means in Ontario.

Common mistakes to avoid

Most of the cases I see fall apart do so for avoidable reasons. Here are the big ones.

• Suing the wrong legal entity. Naming the trade name instead of the corporation, or the owner instead of the company. Run the search and get the name exactly right.
• Suing past the limitation period. Waiting too long is fatal. Generally you have two years from discovering the claim — let it lapse and a strong case can be dismissed on a technicality.
• Suing someone with no money. A judgment you can’t collect is a poor return on your filing fee and your time. Assess collectability before you file, not after.
• Asking for relief the court can’t give. Demanding an injunction, an order forcing a deal through, or a ruling about land ownership. Small Claims awards money and the return of property — frame your claim accordingly.
• Inflating the claim. Padding your damages with amounts you can’t prove hurts your credibility with the judge and can backfire on costs. Claim what you can actually document.

Is suing “on principle” ever worth it?

Honestly, rarely. If your goal is a money recovery you can prove, the court is a good tool. If your goal is to be told you were right, or to extract an apology, the court can’t deliver that — and you’ll spend months and money discovering it. I’d rather tell a prospective client that up front than take a case that can’t give them what they actually want.

What happens in court

If you do decide to proceed, the path is more predictable than people fear. You start by filing a Plaintiff’s Claim (Form 7A) and paying the filing fee, then serving it on the defendant. The defendant has 20 days to file a Defence (Form 9A) under rule 9.01. After that, the court schedules a mandatory settlement conference where a judge reviews the case, gives a candid read on the likely outcome, and tries to broker a settlement. Many cases end right there. The ones that don’t proceed to a short trial before a deputy judge.

The thing to keep front of mind: at every stage, the judge needs a real legal basis — a contract that was breached, a debt that’s owed, property that was damaged or kept. “It’s not fair” is not enough on its own. The whole process is built around proving a recognizable wrong and a quantifiable loss. The procedure is deliberately streamlined: there are no examinations for discovery, the rules of evidence are relaxed, and most trials wrap up in a single day before a deputy judge. That accessibility is the court’s great strength — but it doesn’t change the fundamental requirement that you have a genuine cause of action and the evidence to back it.

Court fees vary depending on whether you’re an infrequent or frequent claimant; rather than quote figures here, run your numbers through the filing fee calculator, or use the Small Claims Court calculator to see what you can claim and confirm you’re in the right court.

Settlement considerations

Something I frequently explain to clients is that suing should rarely be your first move. In many cases, a clear, firm demand letter resolves the dispute without a claim ever being filed. A good demand letter states what is owed, sets out the evidence, gives a deadline, and makes plain that litigation will follow if it’s ignored. The cost is a fraction of a lawsuit, the turnaround is days rather than months, and it shows the court you tried to resolve things first.

Even after a claim is filed, most disputes settle — at the demand stage, at the settlement conference, or somewhere along the way. Very few actually reach a trial. So as you weigh whether to sue, picture the realistic endgame: a negotiated resolution is the most likely outcome, and a well-aimed demand letter is often the cheapest path to it. You can build one in minutes with the Ontario Demand Letter Generator.

Key takeaways

• You can sue for almost any money claim up to $50,000 — but not literally anyone for anything. The court’s jurisdiction is limited, and that’s the catch behind the question.
• Small Claims awards money or the return of property — nothing more. No injunctions, no forcing a deal through, no deciding who owns land.
• Name the right defendant. Sue the corporation by its exact registered name, or the individual owner of an unincorporated business — getting this wrong can sink the case.
• Some disputes belong elsewhere. Residential tenancy matters go to the Landlord and Tenant Board, and claims over $50,000 mean abandoning the excess or going to Superior Court.
• Winning isn’t collecting. Before you sue, ask whether the defendant can actually pay — and whether you’re still inside the two-year limitation period.

Frequently asked questions

Can I sue for any amount in Small Claims Court?

No. Ontario Small Claims Court can only hear claims up to $50,000, not counting interest and costs. That is the monetary ceiling on its jurisdiction, set by regulation. You can sue for any amount at or below that figure, and there is no formal minimum — though for very small claims the cost and time of litigating may not be worth it. If your real loss is more than $50,000, you have two choices: give up (abandon) the part over $50,000 and stay in Small Claims, or bring the whole claim in the Superior Court of Justice instead.

What if my claim is over $50,000?

You cannot simply sue for $80,000 in Small Claims Court. Your options are to abandon the excess — formally give up everything over $50,000 and accept the cap — or to file the full claim in the Superior Court of Justice, which has no monetary ceiling but is slower and more expensive. Abandoning the excess is permanent: you cannot quietly sue for the leftover amount in a second case later, and you cannot split one claim into two to dodge the limit. Whether the trade-off is worth it depends on how much you would be giving up, so it is worth getting advice before you decide.

Can I sue a friend or family member over a loan?

Yes. The law does not care about the relationship — if you lent money and were not repaid, you can sue, friend or relative or not. These cases turn on proof. A written loan agreement, an e-transfer record, a text where they promised to pay you back, or a partial repayment all help establish that it was a loan and not a gift. The hardest version is the handshake loan with nothing in writing, where the other side claims the money was a gift. You can still sue, but you will need whatever corroboration you can find to tip the balance in your favour.

Can I sue a business, and how do I name it?

Yes, but you have to name the business in its correct legal form, and this is where many claims go wrong. If the business is incorporated, you sue the corporation by its exact registered name (for example, "1234567 Ontario Inc." or "ABC Plumbing Ltd."), not the trade name on the sign or the owner personally. If it is a sole proprietorship, you sue the individual owner, who can also be named as carrying on business under the trade name. A business-name search at ServiceOntario or a corporate profile report tells you the real legal entity before you file. Suing the wrong name can sink an otherwise good case.

Can I sue for emotional distress or "on principle"?

Small Claims Court awards money for legally recognized losses — it is not a venue for vindication or an apology. Pure "principle" is not a cause of action; the judge needs a real legal basis, not just that something felt unfair. Emotional distress is only compensable in narrow circumstances, usually where it is tied to a recognized wrong and supported by real evidence, and Small Claims Court is not well suited to those claims. If your main goal is to make a point rather than recover a quantifiable loss, litigation is usually the wrong and most expensive tool for the job.

Can I sue for something other than money?

Only in a limited way. Small Claims Court can order the payment of money or the return of specific personal property worth up to $50,000 — for example, getting back a tool, a vehicle, or equipment that someone is wrongfully holding. It cannot grant an injunction (an order forcing someone to do or stop doing something), it cannot order specific performance of a contract beyond returning personal property, and it cannot decide who owns land. If what you need is a court order changing behaviour rather than money or the return of an item, that belongs in the Superior Court.

Can I sue someone in another province or country?

It is much harder, and often not practical in Small Claims Court. The court generally needs a real connection to Ontario — for example, the contract was made or to be performed here, or the events happened here — before it will take a case against an out-of-province or foreign defendant. Even if you can sue, serving someone abroad and later enforcing an Ontario judgment against assets in another jurisdiction adds cost and complication. Suing within another Canadian province is sometimes workable through reciprocal-enforcement rules; suing internationally is usually a poor fit for Small Claims Court. Get advice before spending money on a cross-border claim.

What can Small Claims Court not decide?

Quite a lot, actually. It cannot grant injunctions or specific performance (beyond returning personal property), it cannot decide title to land, and it cannot hear claims that the legislature has assigned to another forum. Residential landlord-and-tenant disputes generally go to the Landlord and Tenant Board, not Small Claims Court. Family law matters, estate administration, and certain regulatory matters have their own courts and tribunals. It also cannot hear money claims above $50,000 unless you abandon the excess. If your problem is really one of these, filing in Small Claims Court just wastes the filing fee.

Do I need a written contract to sue?

No. Oral (verbal) contracts are enforceable in Ontario, and many breach-of-contract claims succeed without a signed document. The catch is proof: without paper, you have to establish the terms of the deal some other way — through emails, texts, invoices, witnesses, conduct, or a pattern of dealings. A handshake agreement is a real agreement, but in a "he said, she said" dispute the side with corroborating evidence usually wins. So while you do not strictly need a written contract, you do need something beyond your own say-so to prove what was agreed and that it was broken.

What if the person has no money to pay?

This is the question people skip, and it matters more than whether you can win. A judgment is not a payment — it is a court order that money is owed, and collecting it is your job. If the defendant has no income, no bank account, and no seizable assets — what lawyers call "judgment-proof" — even a clear win can be impossible to enforce, and you will have spent filing fees and time for a piece of paper. People's finances change, and there is no limitation period to enforce a judgment, so it is not always hopeless. But before you sue, think hard about whether there is anything to collect.

Final thoughts

So — can you sue anyone for anything in Small Claims Court in Ontario? Almost, but not quite. You can pursue a remarkable range of everyday disputes — unpaid invoices, loans, contractor messes, property damage, deposits, online purchases gone wrong — for any amount up to $50,000. What you can’t do is treat the court as a general fairness tribunal: it awards money and the return of property, on a real legal basis, against the right defendant, within the limitation period, and only where it has jurisdiction.

Get those pieces right and Small Claims Court is one of the most accessible and effective tools Ontario offers. Get them wrong — sue the wrong name, miss the deadline, chase someone with nothing, or ask for relief the court can’t give — and even a sympathetic case goes nowhere. If you’re not sure which side of that line your situation falls on, a short conversation is usually the cheapest way to find out.
