Things can change in an instant. One moment you could be driving to work, taking the exact same route you always take and dealing with the same traffic, when suddenly you're in a car accident. Or you could be recovering from surgery and dealing with unforeseen complications. Maybe you were simply walking through a parking lot on your way to the grocery store, and the next thing you know, you're on the pavement. No matter how your situation started, all you know now is that you have to field calls from insurance adjusters, interpret paperwork you don't fully understand, and look up the definitions of legal terms like "tort claim" as they're thrown around by people who assume you already know what they mean.
Thankfully, you don't have to navigate all of this alone, and you don't have to have all the answers right away. By the end of this article, you'll understand exactly what a tort claim is, how the process of filing one works in Ontario, what deadlines you need to know about, and what your rights are.
Whether you were injured in a car accident, harmed by a negligent medical professional, or hurt while you were on someone else's property, this guide is written for you.
Key Takeaways
Ontario's Limitations Act, 2002 establishes the basic limitation period for most civil claims: two years from the date you knew, or ought reasonably to have known, that you had a claim. This is called the discovery rule, and it is more nuanced than it first appears.
The two-year clock does not always begin ticking on the day of the accident or the date of the medical procedure. This is especially relevant in motor vehicle accident claims, where Ontario Insurance Law requires that an injury be permanent and serious before a tort claim can proceed. In many cases, it is not known on the date of the accident whether the injuries meet that threshold, so the limitation period only begins to run once the injuries are considered permanent and serious. For medical malpractice victims, a similar principle applies: a patient who only later developed symptoms revealing a surgical error does not necessarily lose their claim simply because two years have passed since the operating room date. The clock starts when you knew, or reasonably should have known, that something went wrong and that it caused your injury.
A claim is considered discovered on the day you knew (or reasonably should have known) that injury, loss, or damage occurred; that it was caused by an act or omission of the defendant; and that a legal proceeding would be an appropriate way to seek a remedy.
Several important exceptions apply:
It's important to note that missing any deadline can result in your claim being barred forever. Because legal timelines can be nuanced, it is highly recommended to consult with a legal professional to ensure your specific rights are protected.
|
Type of Claim |

Car Accident (MVA) |
2 years from discovery |
Clock may be paused if injured party was incapacitated; injury must be permanent and serious under Ontario Insurance Law |
|
Medical Malpractice |
2 years from discovery |
Discovery rule often applies — the harm may not be apparent until well after the procedure |
|
Slip and Fall (Private Property) |
2 years from discovery |
None specific, but evidence preservation is critical early on |
|
Slip and Fall (Municipality) |

10-day written notice to the municipality is required under the Municipal Act, 2001 — one of the most frequently missed deadlines in Ontario personal injury law |
|
Product Liability |
2 years from discovery |

|
Intentional Tort |
2 years from discovery |
No limitation period for sexual assault; minors: limitation period does not begin until the child turns 18 |
A tort claim is a formal legal demand (or lawsuit) made by one person against another person or organization because that other party's wrongful conduct caused you harm. The goal of a tort claim is to place you, the injured party, in the financial position you would have been in had the wrongful act never occurred. It's a civil claim, not a criminal one, which means the outcome is compensation.
Ontario residents recovering from a serious injury often hear about two different streams of compensation at the same time, and the distinction between them matters.
Both streams can run simultaneously, and both should be pursued wherever possible. They serve very different purposes, and one does not replace the other.

Not all tort claims arise from car accidents. Ontario personal injury law recognizes a broad range of tort claims, each with its own evidentiary requirements and procedural rules. That's exactly why experienced legal representation matters—what you need to prove, and how you prove it, varies significantly depending on the type of harm you suffered.
Every successful tort claim in Ontario rests on four elements. If even one is absent, the claim will not succeed, which is why thorough investigation and strong evidence matter from the very beginning.
The defendant must have owed you a legal obligation to act with reasonable care. This is rarely the obstacle in personal injury cases. A driver owes a duty to every other person who shares the road. A surgeon owes a duty to every patient on the operating table. A property owner owes a duty to every visitor on their premises. The concept is well-established in Canadian law.
Owing a duty is not enough. The defendant must also have failed to meet the expected standard of care. A driver who runs a red light, a surgeon who leaves a surgical instrument in a patient's abdomen, a municipality that ignores a known hazard on a sidewalk; each of these is an example of a breach of that promise. Duty of care is written to be objective: would a reasonable person in the same circumstances have acted differently?
The defendant's breach must have caused your injury. In Canadian law, courts typically apply the "but for" test: but for the defendant's conduct, would the injury have occurred? In complex cases, particularly medical malpractice, causation is often the most fiercely contested element, requiring expert testimony to establish the link between what went wrong and the harm that followed.
You must have suffered real, measurable harm. This includes physical injuries, psychological harm (such as PTSD or depression), financial losses, and diminished quality of life. Without provable damages, there is no tort claim—even if everything else is present.

Element |
Car Accident Example |
Medical Malpractice Example |
|
Duty of Care |
Every licensed driver owes a duty to other road users to operate their vehicle safely |
A surgeon owes a patient a duty to perform the procedure to the accepted standard of care |
|
Breach of Duty |
The driver ran a red light, was speeding, or was distracted by a phone |
The surgeon left a foreign object in the patient's body, or failed to obtain informed consent |
|
Causation |
But for the driver running the red light, the collision would not have occurred |
But for the surgeon's error, the patient would not have suffered nerve damage or infection |
|
Damages |
Broken vertebrae, loss of income, ongoing physiotherapy costs, and chronic pain |
Permanent disability, lost career, future care needs, and psychological trauma |
A tort claim notice is a formal, written notification to the party you intend to sue, or, in certain situations, to a government body, informing them that you are asserting a legal claim. Missing a tort claim notice deadline can permanently bar a valid claim, even if the injury is severe and the negligence is clear. This is one of the most consequential and frequently misunderstood aspects of Ontario personal injury law.
Ontario applies different notice requirements depending on who the defendant is:
Pursuing a tort claim against a government body in Ontario, whether that is a municipality, a provincial agency, or a Crown corporation, involves additional procedural layers beyond what applies to private defendants. These bodies often have specific forms, designated offices for receiving notice, and strict timelines that must be respected.
If you have been seriously injured, thinking about legal processes is probably the last thing you want to do, since you're busy managing your pain, medical appointments, financial stress, and an uncertain future. But the legal process itself doesn't have to be overwhelming, especially when you have experienced guidance from the first step.
Here is a plain-language walkthrough of how filing a tort claim in Ontario generally works.
The steps above tell you what to do. Equally important is what not to do, because mistakes in the early stages of a tort claim can permanently damage your case.
Without a thorough review of the specific facts of your case, a lawyer can't tell you what your tort claim is worth. Anyone who quotes you a number before knowing the details of your injury, your income, your treatment needs, and the available evidence isn't giving you accurate information.
What can be said is that Ontario tort claims compensate injured people across a defined set of damage categories. Understanding what is available is an important first step.

When you first encountered the word "tort," it may have felt like part of a language you were never meant to understand. But a tort claim is, at its core, something very straightforward: it is the legal path that allows someone who has been wrongfully harmed to pursue fair compensation from the person or organization responsible.
The process has steps. Those steps have deadlines. And the decisions you make in the earliest weeks (i.e., who you speak to, what you sign, whether you seek legal advice) can determine whether you recover what you are truly owed or settle for far less than your injury demands.
To retiterate, time is the single most important factor in any Ontario tort claim. Waiting does not make the process simpler. It reduces your options.
