- A simple, uncontested civil claim that settles early can resolve in 6 to 12 months.
- A contested matter proceeding to trial in the Ontario Superior Court commonly takes 2 to 4 years, sometimes longer.
- Most civil lawsuits settle before trial — often at or after the discovery stage, once both sides understand the strength of the evidence.
- The Rules of Civil Procedure impose strict deadlines at each stage, and missing them can delay your case or result in penalties.
- Toronto and GTA courthouses generally have longer scheduling backlogs than smaller Ontario jurisdictions, especially for trial dates.
- Early, well-prepared litigation strategy is the single biggest factor in avoiding unnecessary delay.
The Short Answer: 6 Months to Several Years
There is no single answer to how long an Ontario civil lawsuit takes, because it depends entirely on how many of the case's stages are actually contested. A matter that resolves through early negotiation might close out in 6 to 12 months. A fully contested action that proceeds all the way through discovery, motions, and trial in the Ontario Superior Court of Justice can easily take 2 to 4 years, and complex commercial or multi-party litigation can take even longer.
Understanding the stages of a civil lawsuit — and where delay typically creeps in — helps set realistic expectations from the outset, whether you are the party suing (the plaintiff) or being sued (the defendant).
The Stages of a Civil Lawsuit in Ontario
Civil litigation in the Ontario Superior Court of Justice generally moves through four broad stages, each governed by the Rules of Civil Procedure:
- Pleadings — the Statement of Claim, Statement of Defence, and any counterclaims that define the issues in dispute.
- Discovery — the exchange of documents and oral examinations that allow each side to understand the other's case.
- Motions and pre-trial procedures — including mandatory mediation in some jurisdictions, and pre-trial conferences with a judge.
- Trial — a formal hearing where a judge (and occasionally a jury) decides the outcome, if the matter has not already settled.
Pleadings Stage: 1 to 6 Months
The lawsuit formally begins when the plaintiff issues a Statement of Claim, which must then be served on the defendant. A defendant who has been served within Ontario generally has 20 days to file a Statement of Defence (40 days if served elsewhere in Canada or the United States, 60 days if served outside North America).
If a defendant fails to respond within the deadline, the plaintiff can move for default judgment, which can conclude this stage quickly. If the defendant disputes the claim and files a defence — and possibly a counterclaim — the pleadings stage typically closes within a few months, setting the stage for discovery.
Discovery Stage: 6 Months to Over a Year
Discovery is often the longest and most document-intensive stage of a civil lawsuit. Each party must serve an Affidavit of Documents listing all relevant documents in their possession, followed by oral examinations for discovery, where each party is questioned under oath by the opposing lawyer.
Why Discovery Takes So Long
Gathering and organizing documents — particularly in commercial disputes involving emails, contracts, financial records, and correspondence — takes time. Scheduling examinations for discovery around lawyers' and parties' availability adds further delay, and disputes over the scope of disclosure can require a motion to resolve.
Cases with organized, complete documentation from the outset move through discovery significantly faster than cases where records are scattered or incomplete. Start organizing your evidence — contracts, invoices, correspondence — as early as possible, ideally before you even file.
Motions & Pre-Trial Procedures: Several Months
Many Ontario civil actions — particularly in Toronto, Ottawa, and Windsor — are subject to mandatory mediation under Rule 24.1, which must generally occur within 180 days of the first defence being filed, though extensions are common. If mediation does not resolve the dispute, the matter proceeds toward a pre-trial conference, where a judge helps narrow the issues and encourages settlement before trial.
Interlocutory motions — for example, disputes over the scope of document production, or a motion for summary judgment — each require separate scheduling and can add months to a case, particularly in busier courthouses with limited motion court availability.
Trial Stage: Often the Longest Wait
If a matter does not settle, it proceeds to trial. In busy jurisdictions like Toronto, trial dates are frequently scheduled a year or more in advance once a matter is deemed “set down” for trial, due to significant court backlogs. Trials themselves can last anywhere from a single day for a straightforward matter to several weeks for complex, multi-witness commercial litigation.
Step-by-Step Civil Litigation Timeline
What Slows a Civil Lawsuit Down
Delays in producing documents, or disputes over what must be disclosed, are among the most common causes of slowdown during discovery.
Every additional party adds coordination, additional pleadings, and additional discovery — significantly extending the overall timeline.
Toronto and other high-volume GTA courthouses often have longer waits for motion dates, pre-trial conferences, and trial dates than smaller Ontario jurisdictions.
Disputes over procedure, disclosure, or preliminary legal issues each require their own scheduling and hearing, adding months to a case.
Matters requiring expert reports — such as valuations, engineering assessments, or forensic accounting — take additional time to prepare, exchange, and potentially challenge.
How to Move Your Case Faster
- Organize your evidence early. Complete, well-organized documentation dramatically speeds up the discovery stage.
- Respond promptly to opposing counsel. Delays in responding to requests are a common, avoidable cause of slowdown.
- Engage seriously with mediation. A genuine effort to settle at mediation can avoid the lengthiest and most expensive remaining stages entirely.
- Avoid unnecessary motions. Every motion adds scheduling delay — reserve them for issues that genuinely require court intervention.
- Retain experienced counsel early. A lawyer familiar with local court procedures and scheduling can avoid avoidable errors and delay.
Two businesses in a contract dispute exchange complete documentation promptly after the pleadings close, attend mediation in good faith six months later, and reach a negotiated settlement — resolving the matter in under a year. A similar dispute between parties who each delay disclosure and bring multiple motions can take three years or more to reach the same result, at significantly higher cost.

Frequently Asked Questions
If the defendant does not dispute the claim, or the parties settle shortly after the Statement of Claim is served, a matter can resolve within a few months. Claims that proceed to a Motion for Default Judgment because the defendant never responds can also resolve relatively quickly.
Trials are expensive, time-consuming, and carry litigation risk for both sides. Once discovery is complete and both parties understand the strength of the evidence, most litigants prefer the certainty of a negotiated settlement over the cost and unpredictability of trial.
Discovery — including the exchange of documents (Affidavit of Documents) and oral examinations for discovery — commonly takes 6 months to over a year, depending on the complexity of the matter and the number of parties and documents involved.
Yes, to a degree. Responding promptly to requests, providing complete disclosure early, exploring mediation, and avoiding unnecessary motions can all reduce delay. However, some delay is driven by court scheduling backlogs outside any party's control.
Many Ontario Superior Court civil actions in Toronto, Ottawa, and Windsor are subject to mandatory mediation. If mediation is unsuccessful, the matter continues toward a pre-trial conference and, ultimately, trial if no settlement is reached.
In busier jurisdictions like Toronto, trial dates are often scheduled a year or more in advance once a matter is ready for trial, due to significant court backlogs.
Not directly — but higher-value or more complex claims often involve more parties, more documents, and more expert evidence, all of which tend to extend the timeline compared to a straightforward, lower-value dispute.
