How to Sue Someone in Small Claims Court in Ontario

Deciding to sue someone is rarely an easy decision. Whether someone owes you money, failed to honour a contract, or caused financial loss through their actions, taking legal action can feel like a significant step. Before filing a claim, it’s important to understand whether you have a valid legal basis, whether Small Claims Court is the right place to resolve your dispute, and what you should do to prepare.

To sue someone in Ontario Small Claims Court, you’ll generally need to confirm that your claim qualifies, gather supporting evidence, complete and file the required court forms, serve the defendant, and follow the court process until your case is resolved. 

If you’re wondering how to sue someone in Ontario Small Claims Court, this article will walk you through the key considerations and steps of starting a claim, and help you understand whether pursuing legal action is the right next step. 

Step 1: Confirm That Your Claim Qualifies for Small Claims Court

Before starting a claim, make sure your dispute falls within the jurisdiction of the Ontario Small Claims Court.

The Small Claims Court generally hears civil disputes involving money or the recovery of personal property, subject to the court’s monetary limit of $50,000. Common examples include:

  • Unpaid loans or invoices
  • Breach of contract
  • Property damage
  • Unpaid services
  • Consumer or business payment disputes

Not every legal dispute belongs in Small Claims Court. Family law matters, criminal cases, bankruptcy proceedings, and many landlord and tenant disputes are generally handled by different courts or tribunals.

If you’re unsure whether Small Claims Court is the right forum for your dispute, obtaining legal advice before filing can help you avoid unnecessary time and expense.

Step 2: Gather the Evidence to Support Your Claim

Strong evidence is the foundation of a successful Small Claims Court claim. Before filing, organise any documents that help establish what happened, what was agreed upon, and the financial loss you suffered.

Depending on your case, this may include:

  • Contracts or written agreements
  • Invoices, receipts, or proof of payment
  • Emails and text messages
  • Photographs or videos
  • Repair estimates or financial records
  • Any other documents relevant to the dispute

If other people witnessed the events, make a note of who they are and what information they may be able to provide if required.

Having evidence does not automatically mean you’ll win your case. The court considers the relevance, credibility, and overall strength of the evidence presented by both parties before making a decision.

Step 3: Complete and File Your Claim

Once you’ve confirmed your claim qualifies and gathered your evidence, the next step is to prepare and file your claim.

This involves completing the appropriate Small Claims Court forms, accurately setting out the facts of your case, the amount you’re claiming, and the legal basis for your claim. Providing clear, complete, and accurate information can help reduce delays and avoid the need to correct or amend your documents later.

After completing the required forms, you’ll need to file them with the appropriate Ontario Small Claims Court and pay the applicable court filing fee.

Before filing, take time to review your claim carefully. Make sure names, dates, addresses, amounts claimed, and supporting information are accurate and consistent with your evidence.

While this article provides an overview of the process, we’ve explained each filing step in greater detail in our guide on How to File a Small Claims Court Claim in Ontario, including the required forms, filing options, court fees, and procedural requirements.

Step 4: Serve the Defendant

After filing your claim, you’ll need to ensure the defendant receives a copy of the claim in accordance with the Rules of the Small Claims Court. This is known as serving the defendant.

Serving court documents correctly is an important part of the legal process. If service isn’t completed properly, your case may be delayed, or the court may require you to take additional steps before the matter can proceed.

Once the defendant has been served, they have an opportunity to respond within the time allowed under the applicable court rules.

Step 5: Prepare for the Next Stages of the Court Process

After your claim has been filed and served, the case may move through several stages before it’s resolved.

If the defendant files a defence, the court may schedule a settlement conference where both parties have an opportunity to discuss the dispute, clarify the issues, and explore whether the matter can be resolved without a trial.

If no settlement is reached, the case may proceed to a hearing where both parties present their evidence and arguments before a deputy judge, who will make a decision based on the facts and the law.

Throughout the process, it’s important to keep your documents organised, meet all court deadlines, and be prepared to support your claim with clear evidence.

Common Mistakes to Avoid

Avoiding common mistakes can help your claim proceed more smoothly. Before and during the Small Claims Court process, keep these points in mind:

  • Filing in the wrong court or tribunal.
  • Waiting too long to start your claim.
  • Failing to keep supporting documents organised.
  • Providing incomplete or inaccurate information in court forms.
  • Not serving the defendant according to the court rules.
  • Missing court deadlines or scheduled appearances.

Taking the time to prepare your claim carefully can reduce unnecessary delays and improve your ability to present your case effectively.

When Legal Guidance May Help

You don’t need a lawyer to file a Small Claims Court claim, but legal guidance can be valuable in certain situations.

If your case involves disputed contracts, conflicting evidence, multiple parties, or complex legal issues, speaking with a lawyer before filing can help you better understand your rights, obligations, and available options. Even if you plan to represent yourself, obtaining legal advice early may help you avoid procedural mistakes and approach your case with greater confidence.
