Responding to a Small Claims Court Claim: A Deeper, Example-Driven Guide

Every defendant's situation is a little different, but the underlying task is the same: understand exactly what's being claimed, decide how you genuinely want to respond, and get that response filed correctly before your deadline. This guide walks through that process in detail, with the kind of examples and edge cases a quick checklist doesn't have room for. If you just need the fast, step-by-step version, see our quick-start response checklist instead.

What you were actually served with

Most defendants receive a document called a Plaintiff's Claim. It's worth understanding its structure before you decide anything, because a claim is rarely just "you owe me money" — it's usually built from several distinct pieces stacked together.

• The principal amount. The core sum the plaintiff says you owe, before anything else is added.
• Interest. Many claims add interest on top of the principal, calculated from a date the plaintiff specifies.
• Costs. Court fees and certain other expenses the plaintiff is asking you to reimburse if they win.
• The particulars. A written narrative explaining what happened and why the plaintiff believes you're responsible. This section is where most of the actual dispute lives.

Since October 1, 2025, Ontario's Small Claims Court monetary limit is $50,000, exclusive of costs and interest — up from the previous $35,000 limit. That means the principal amount you're being sued for should generally fall within that ceiling; if a claim's principal appears to exceed it, that alone can be worth raising.

Separating these pieces matters because it's common for a claim to be entirely accurate on the principal but wrong on the interest calculation, or vice versa. Treating the total dollar figure as one indivisible number tends to make people miss defensible pieces of an otherwise valid claim.

The clock starts the moment you're served

The single most consequential fact in this entire process is the date you were served — not the date you read the claim, not the date you finally sat down to deal with it, but the date it was formally delivered to you in a way the court's rules recognize. Your deadline to file a response is calculated from that date, and it is generally treated strictly.

It's worth saying plainly: needing more time to feel "ready" is not the same as having more time on the calendar. Courts generally expect a response by the stated deadline regardless of how complicated your situation feels. If you genuinely need extra time, ask for it — either informally from the plaintiff or, in limited circumstances, from the court — rather than simply letting the date pass.

Reading the claim like a checklist, not a story

Once you know your deadline, read the claim a second and third time, slower than the first. The goal on this pass isn't to react emotionally to the narrative — it's to extract a list. For each specific fact alleged in the particulars, decide: do I agree this happened, do I disagree, or do I genuinely not know?

Take a contractor dispute as an example. A plaintiff might allege that work was completed on a specific date, that an invoice for a specific amount was issued, and that it remains unpaid. A defendant might agree the work happened, but dispute the date it was finished, the quality of the work, or the amount actually owed under the contract. Breaking the claim into these discrete pieces — rather than reacting to "he's suing me for $6,000" as one lump fact — is what actually produces a strong, specific Defence later.

This is also the point to check whether the claim was brought within Ontario's general two-year limitation period under the Limitations Act, 2002, which generally runs from the day the plaintiff knew, or reasonably should have known, about the claim. If the underlying dispute is old, this can be worth investigating — see our companion article on common defences for more on how a limitations argument actually works in practice.

Your four real response paths

Once you've separated fact from dispute, most defendants land in one of four broad positions. None of these require total certainty right away — they require picking a direction before your deadline and refining it as you go. If you'd rather work through this interactively, the being sued wizard walks through the same decision points in order and helps you land on which path fits your situation.

Whichever path fits, doing nothing at all isn't really a fifth option — it's a decision by default, and it's covered in detail in our article on what happens if you miss a deadline.

A quick example, start to finish

Say a landscaping company sues a homeowner for $4,200, claiming unpaid invoices for spring and summer work. The homeowner's first instinct is panic at the total. Working through the process above changes that. Breaking the claim apart, the homeowner agrees the spring work happened and was invoiced correctly at $1,800, but disputes the summer invoice of $2,400 because the promised drainage repair was never actually completed.

Under the four-path framework, this homeowner lands on "dispute part of it." Their Defence admits the $1,800 spring invoice, disputes the $2,400 summer invoice specifically because the work described wasn't performed, and attaches photos and a text message exchange with the landscaper acknowledging the drainage issue was never resolved. That's a far stronger, more credible position than either paying the full $4,200 out of anxiety or filing a bare denial of the entire claim. The specificity is what does the work — a judge, or the plaintiff themselves at a settlement conference, can see exactly what's actually in dispute and why.

Filing your response: the practical mechanics

Once you've decided to file a Defence, the mechanics themselves are fairly standard. You'll need the correct court form, completed with your response to the claim, filed with the same court office the claim was issued from, along with the applicable fee. Because form numbers and fee schedules are updated from time to time, use the official sources directly rather than relying on a number from memory: see the Ministry of the Attorney General's Small Claims Court forms page and the Ontario Court Forms portal for the current Defence form, and our own court forms and filing fees pages for a plain-language overview.

Filing a Plaintiff's Claim generally costs $108 for most individuals and small businesses, or $228 for a plaintiff who has filed 10 or more claims at the same court office within a calendar year — that's the plaintiff's fee, not yours, but it's a useful reference point for understanding the fee structure. A Defence generally involves its own separate court fee, which you'll want to confirm on the filing fees page above before you file.

What happens after you respond

Once your Defence is on file, a defended case generally moves toward a settlement conference — a required, relatively informal step before trial where a large share of contested cases actually resolve. From there, if the case doesn't settle, it proceeds through further pre-trial steps and, eventually, trial if necessary. For the full sequence, see the Ontario Superior Court of Justice's guide to the Small Claims Court process.

Common mistakes worth avoiding

• Responding to the total dollar figure instead of the specific allegations that make it up.
• Assuming a phone call or email to the plaintiff satisfies your formal deadline to file.
• Filing a one-line denial instead of addressing each allegation in the particulars.
• Forgetting to serve the plaintiff after filing your Defence with the court.
• Waiting to gather evidence until a settlement conference is already scheduled.

What to do next

1. Confirm the exact date you were served and calculate your firm response deadline.
2. Read the claim line by line, separating what you agree happened from what you dispute.
3. Decide which of the four response paths best fits your situation right now.
4. Gather the documents and communications that support your position.
5. File and serve your response well before your deadline, not on the last possible day.
