Receiving a Statement of Claim or court judgment can feel overwhelming. But whether you’ve just been sued or have already lost at first instance, Ontario law gives you structured procedural rights — to defend, to settle, and, when necessary, to appeal.
Being sued doesn’t mean you’ve done anything wrong, and losing at trial doesn’t mean justice ends there.
The Rules of Civil Procedure and the Courts of Justice Act give every litigant the opportunity to respond, correct procedural unfairness, and challenge errors of law or fact.
This guide explains what to do the moment you’re sued, how to defend effectively, and — if judgment goes against you — how to appeal or stay enforcement.
Step 1: Identify What You’ve Been Served With
Before reacting, determine what document you’ve received. This dictates your deadlines, options, and forum.
Document Type | Court Level | Purpose |
Statement of Claim | Superior Court of Justice | Ordinary civil lawsuit seeking damages or relief |
Notice of Application | Superior Court | Decided mainly on written affidavits, not oral evidence |
Plaintiff’s Claim | Small Claims Court | Civil claim up to $35,000 |
Notice of Appeal | Divisional Court / Court of Appeal | Initiates appellate review of a judgment |
Always read the first page carefully — it identifies the court, parties, and response deadlines.
Step 2: Note the Deadlines
Timeliness is everything.
Court | Deadline to Respond / Defend | Governing Rule |
Superior Court (Statement of Claim) | 20 days (Ontario), 40 days (outside Canada/US) | Rule 18.01 |
Small Claims Court | 20 days | Rule 9.01 (Small Claims Rules) |
Application | As stated in Notice of Application | Rule 38.09 |
Notice of Appeal (Divisional Court or Court of Appeal) | 30 days from judgment (unless extended) | Rules 61.04 & 61.16 |
Tip: A missed deadline can lead to default judgment or loss of appeal rights. Act immediately — extensions are discretionary and not guaranteed.
Step 3: Contact a Litigation Lawyer Immediately
Consult a qualified civil litigation or appellate lawyer within 48 hours of being served.
A lawyer will:
- Review the claim or judgment for procedural defects and appealable errors;
- File a Notice of Intent to Defend, Statement of Defence, or Notice of Appeal;
- Advise whether to settle, defend, or appeal strategically;
- Preserve limitation periods and appeal rights.
If you’re a corporation, you must be represented by counsel in the Superior Court or Court of Appeal.
Step 4: Preserve All Evidence
Collect every relevant record — contracts, correspondence, invoices, and witness notes.
Under Rule 30, you must disclose all relevant documents in your possession or control.
In appeals, the record below becomes critical. Missing evidence can weaken or eliminate grounds for appeal.
Case Example:
Hryniak v. Mauldin, 2014 SCC 7 — emphasizes efficient, proportionate litigation and the importance of early, organized evidence.
Step 5: File Your Defence or Response
Depending on the nature of the proceeding:
- Statement of Defence (Rule 25) – Deny or admit allegations and raise affirmative defences.
- Responding Record (Applications) – File affidavit evidence and legal argument.
- Defence (Small Claims Court) – File Form 9A within 20 days.
Missing this step allows the plaintiff to obtain a default judgment under Rule 19.
Step 6: Explore Early Settlement or Resolution
Ontario courts strongly encourage early resolution.
- Mandatory Mediation (Rule 24.1): Required in Toronto, Ottawa, and Windsor.
- Rule 49 Offers to Settle: Impacts cost recovery.
- Judicial Pre-trials: Judges may facilitate negotiated resolution.
Case Reference: Hamilton v. Open Window Bakery Ltd., 2004 SCC 9 — reinforces the duty of good faith in contractual dealings, often guiding settlement behaviour.
Step 7: Understand the Judgment Process
If the matter proceeds, the court may:
- Dismiss the claim;
- Award judgment against you (damages, injunction, or declaration);
- Grant costs and interest under section 130 of the Courts of Justice Act.
At this stage, enforcement can begin unless a stay of enforcement is granted (Rule 63.01).
Step 8: Considering an Appeal
If you believe the judgment was unfair, legally incorrect, or procedurally flawed, Ontario law provides a structured appellate path.
- When You Can Appeal
You may appeal if:
- The judge made an error of law, fact, or mixed fact and law;
- The court exceeded its jurisdiction;
- The decision resulted in procedural unfairness; or
- There is a palpable and overriding error in factual findings.
Key Cases:
- Housen v. Nikolaisen, 2002 SCC 33 — sets out the standard of review (errors of law vs. fact).
- Benhaim v. St-Germain, 2016 SCC 48 — confirms deference to trial findings unless clearly wrong.
- Ash v. Lloyd’s Corp., 2017 ONCA 385 — outlines appellate procedure and the need for clear grounds.
- Where to Appeal
Original Court | Appeal To | Relevant Rule |
Small Claims Court | Divisional Court (within 30 days) | Rule 62 / CJA s. 19(1)(a) |
Superior Court (Single Judge) | Divisional Court (by right, or with leave) | Rule 61.04 |
Divisional Court | Court of Appeal for Ontario | Rule 61.04 |
Court of Appeal | Supreme Court of Canada (by leave only) | Supreme Court Act, s. 40 |
- Steps in the Appeal
- File Notice of Appeal (Form 61A) within 30 days.
- Order transcripts and prepare the Appeal Record and Factum (Rule 61.09).
- Serve all parties and file with the appropriate court.
- Consider a Stay of Enforcement pending appeal (Rule 63).
- Attend the appeal hearing, where a panel of judges reviews the record below.
- Possible Appeal Outcomes
- Appeal dismissed – judgment stands.
- Appeal allowed – judgment set aside or varied.
- New trial ordered – case sent back for reconsideration.
Step 9: Post-Judgment Enforcement or Relief
Even if you lose, enforcement isn’t automatic.
You can:
- Seek a payment schedule or negotiated settlement;
- Bring a motion for stay pending appeal;
- File a Notice of Appeal within 30 days to pause or mitigate collection;
- Explore post-judgment remedies (see ME Law’s Guide: How to Enforce a Judgment in Ontario).
Practical Guidance for Defendants and Appellants
- Act immediately. Procedural rights expire quickly.
- Preserve your record. Appeals depend on transcripts and exhibits.
- Avoid public commentary. Keep communications professional and private.
- Evaluate cost-benefit. Appeals must balance legal merit with economic reality.
- Get experienced counsel. Appellate advocacy is a distinct skill set.
