When you’ve been injured in an accident, the first thing on your mind is probably getting better. But while you’re recovering, there’s another critical question to answer: how long to file a personal injury claim in Ontario, and whether you’re already running out of time. Ontario has strict time limits, and if you miss them, you could lose out on what you’re owed. This guide breaks down how long you actually have to file a personal injury claim, and what happens if you don’t act fast enough.
Key Takeaways
- In most cases, you have two years from the date of injury or discovery to file a personal injury claim.
- Car accidents have extra deadlines: notify your insurer within 7 days and the at-fault party within 120 days.
- For slip and fall claim, if you slip on municipal property, you only have 10 days to give notice.
- The two-year clock can be paused for minors (until they turn 21) or if you were mentally incapable of acting.
- Missing deadlines can mean losing your right to compensation, so it’s best to consult a lawyer early.
The Basic Rule: Ontario’s 2-Year Limitation Period
If you’re wondering how long to file a personal injury claim in Ontario, here’s the core answer: you generally have two years from the date of your injury to start a lawsuit. This time limit is set out by the Limitations Act, 2002. It might sound simple, but there are details you really need to pay attention to, since missing the deadline can totally shut down your right to compensation, even if your case would have been strong.
What the Ontario Limitations Act 2002 Says
- The law says you have two years from the date you “discover” your injury to bring a claim.
- “Discover” means when you knew (or should have known) that you were harmed and someone else was at fault.
- Even if the injury happened a while ago, if you only learned about its cause later, your two years might start then.
Cases get thrown out all the time because people misunderstand when they need to act—don’t let that be you.
When Does the Clock Actually Start Ticking?
A lot of people get tripped up by this. It’s easy to think the deadline is just about the calendar date of the accident, but that’s not always true. Ontario uses what’s called the “discoverability rule”:
Here’s what kicks off the countdown:
- You know you’ve been injured.
- You realise (or should have with reasonable effort) that someone else might be responsible.
- You understand that a lawsuit is an option for solving the problem.
For some, all that happens at once—like a slip and fall with a broken leg. For others, especially with tricky or hidden injuries, it can take weeks or even months.
Just keep in mind, waiting even if you think you have lots of time can make things harder. Early action gives you the best shot at having your claim taken seriously before evidence disappears or memories fade.
Exceptions That Can Shorten Your Window (Act Fast)
While the general two-year rule applies to most claims, some situations demand you move much quicker. These aren’t just suggestions; they’re strict rules that can shut down your case before it even gets going if you miss them. It’s like a ticking clock, but sometimes that clock has a much shorter fuse.
Car Accidents: The 7-Day & 120-Day Statutory Notice Rules
If you’ve been in a car accident in Ottawa, you need to be aware of a couple of important deadlines that pop up way before the two-year mark. First off, you generally have just seven days to notify your insurance company about the accident to access certain benefits, like income replacement or medical care. This is often done by submitting an OCF-1 form. Missing this initial notification can delay or even deny you access to these crucial no-fault benefits.
Then there’s the 120-day rule. While not a formal lawsuit deadline, it’s a critical notice period for certain types of claims, especially those involving specific insurance disputes or if you’re dealing with a more complex accident scenario. It’s always best to get advice on this sooner rather than later.
Slip & Fall on Municipal Property: Only 10 Days to Notify
This one really catches people out. If you slip and fall on property owned by a city or municipality here, you have a drastically shorter window to formally notify them of your intention to claim. We’re talking about just 10 days from the date of the incident. This notice requirement is separate from the main two-year limitation period for filing a lawsuit. Failing to provide this written notice within the 10-day window can completely bar your claim against the municipality, even if your injuries are severe and the municipality was clearly at fault. It’s a tough rule, and it highlights why immediate action is so important after a fall on public property. Getting legal advice quickly after such an incident is key to making sure this notice is properly filed within the tight timeframe. It’s a good idea to get professional help to file a municipal claim if this happens to you.
Exceptions That Can Extend Your Deadline
In reality, the standard two-year rule is pretty straightforward for most personal injury claims in Ontario. But sometimes, life throws you a curveball, and the clock doesn’t start ticking right away, or it gets paused altogether. This is super important because missing out on these exceptions could mean you miss your chance to get compensation, even if you thought you had plenty of time.
Minors and Mentally Incapable Persons
If the injured person is under 18, or if they’re an adult but lack the mental capacity to understand or manage their legal affairs, the usual time limits get put on hold. Think of it as a pause button. The clock doesn’t start running until that person turns 18 or regains their mental capacity. This is to make sure that vulnerable individuals aren’t disadvantaged because they can’t take legal action themselves. It gives them, or someone acting on their behalf, a fair go once they’re in a position to do so.
The “Discovery Rule” — When You Didn’t Know You Were Injured
This one’s a bit more complex and often comes up in cases where the injury isn’t immediately obvious. It’s called the “discoverability” rule. Basically, the two-year clock doesn’t start until you knew, or reasonably should have known, that you suffered an injury and that this injury was caused by someone else’s actions or negligence. This is particularly relevant in situations like:
- Medical Malpractice: Sometimes, the effects of a medical error don’t show up for months or even years. You might have had surgery, and only later realise there was a complication due to negligence.
- Latent Injuries: Think about exposure to certain substances at work that cause long-term health problems, or injuries that develop gradually over time.
It’s not about when the incident happened, but when you genuinely discovered the injury and its cause. However, the law also says you can’t just ignore obvious signs forever. There’s a limit to how long you can ‘discover’ something, often capped at 15 years from the original act, even if you only find out about the injury later.
It’s easy to think you have ages to sort out a claim, especially if you’re still recovering or the injury seems minor at first. But the law is pretty strict about deadlines, and these exceptions are there for specific, often unavoidable, reasons. Relying on them without understanding the details can be risky business.
What Happens If You Miss the Deadline?
A lot of people don’t realise this, but missing a personal injury deadline in Ontario pretty much slams the door on your right to compensation. It doesn’t really matter how strong your case looked earlier. Once that limitation period has expired, courts generally won’t even look at your claim unless you qualify for a rare exception.
Can You Still Recover Any Compensation?
Once the clock runs out, these are your usual options (and as you’ll see, they’re not great):
- File Anyway and Hope for a Miracle: Some people still try to file. The court will usually dismiss it unless you can prove a valid exception (like you were legally incapable, or your injury was only discovered much later).
- Try to Negotiate with the Insurer: Insurers have zero incentive to settle once you’ve missed the cut-off. You’ve lost all legal leverage.
- Seek a Legal Exception: A lawyer can look at your situation and see if there’s any wiggle room, but these cases are rare and tough.
It’s easy to think a day or week won’t matter, but the law is strict. Even strong facts won’t help if you’re out of time. Missing that deadline usually means losing any shot at proper compensation.
So, if you’re getting close to the cut-off, it’s best to talk to a personal injury lawyer fast. Even if you’re not sure about your case, better to know for certain than end up with nothing just due to timing.

Why You Shouldn’t Wait Even If You Have 2 Years
Now that you know how long to file a personal injury claim in Ontario, you might think two years sounds like plenty of time. But honestly, waiting that long is a bit like leaving your Christmas shopping until Boxing Day – you might get there, but it’s going to be way harder than it needed to be.
Evidence Disappears, Witnesses Forget
Think about it. The scene of an accident, especially if it’s outdoors, can change in minutes. Rain washes away skid marks, snow covers up hazards, or maybe someone just tidies up. If you’re injured because of a faulty product, that product might get lost or repaired before anyone can properly examine it. And witnesses? People’s memories aren’t like video recordings. What seems crystal clear today can get fuzzy in a few months. The sooner we can get to the evidence, the stronger your case will be. This includes things like security camera footage, which often gets overwritten after a certain period. It’s not about rushing you, it’s about making sure the facts are still there when we need them.
Insurance Companies Use Delay Against You
Insurance companies are businesses, and their goal is to pay out as little as possible. If you delay, they’ll use that delay to their advantage. They might argue that because you waited, it’s harder for them to investigate, or they might even suggest your injuries aren’t as bad as you claim because you didn’t seek immediate treatment or file a claim right away. They know that evidence degrades over time, and they’re happy to let that happen. Sometimes, they might even try to settle with you for a much lower amount if they think you’re desperate or unaware of your rights. It’s always better to have a lawyer looking out for you from the start, especially when dealing with long-term disability claims or other insurance matters.
Waiting too long can create procedural hurdles that make it difficult, if not impossible, to get fair compensation, even if your injury was clearly someone else’s fault. It’s not just about the legal deadline; it’s about preserving the actual ability to prove your case.

Frequently Asked Questions
What’s the main time limit for lodging a personal injury claim in Ontario?
Generally, you’ve got two years from the date you were injured, or from when you realised you were injured because of someone else’s actions, to start a claim. Think of it as a ticking clock that starts when you know you’ve been hurt and who might be responsible.
Can I still claim if I missed the two-year deadline?
It’s tough, but sometimes yes. If the injured person was under 18 at the time of injury, the clock doesn’t start until they turn 18, giving them until they turn 20 to file. Also, if the injury wasn’t obvious straight away, the clock might start later when you discover it. It’s best to chat with a legal expert to see if your situation fits an exception.
What happens if I don’t lodge my claim on time?
If you miss the deadline, the court will likely say you can’t make a claim anymore. This means you probably won’t be able to get any money for your injuries, medical bills, or lost wages, even if someone else was clearly at fault.
Do I really need a lawyer for a personal injury claim?
You don’t absolutely have to have a lawyer, but it’s a really good idea. Lawyers know all the tricky rules and deadlines, and they can make sure you file everything correctly and on time. They can also help you get the most money possible for your injuries, especially if the case is complicated.
Are there special rules for car crash claims?
Yep, car accidents have a few extra steps. You need to tell your insurance company within seven days and send in your accident benefits claim within 30 days. If you plan to sue the other driver, you usually need to give them written notice within 120 days, on top of the two-year limit for the actual lawsuit.
What if I slipped and fell on council property, like a sidewalk?
If you get hurt on property owned by the council or a city, you have to tell them in writing really quickly – usually within just 10 days! Even though you still have two years to file the actual lawsuit, you must give them that early notice, or your claim might be blocked.
