A personal injury limitation period in Ontario is a legal deadline for starting a claim; in many injury cases, the basic deadline is two years from when the claim was discovered, but exceptions and separate deadlines can apply. Missing a deadline may put a claim at risk, so do not assume that waiting for treatment, an insurer’s decision, or a full diagnosis will stop the clock.

What Is a Limitation Period, and Why Does It Matter for Your Injury Claim?
A limitation period is the time allowed by law to begin a legal proceeding. It is not simply a recommended date for finishing paperwork. If a limitation period expires, the other side may argue that the claim is out of time. That can create a serious obstacle, even when an injured person has a genuine dispute about responsibility or losses.
Ontario residents often have more than one process to consider after an accident. A claim against a person or organization alleged to have caused an injury is generally called a tort claim. A claim for benefits under an automobile insurance policy follows a separate statutory process. The deadlines, documents, and steps are not interchangeable. Taking action on one track does not necessarily preserve rights on the other.
Deadlines can be difficult to assess while you are in pain, caring for a family member, attending appointments, or waiting for an insurer to respond. Keep a written record of important dates and get legal advice early if you are unsure which rules apply. Hoffman Law serves injured people across Ontario, including Toronto and North York.

Personal Injury Limitation Period Ontario: The Basic Two-Year Rule
For many personal injury claims, Ontario’s basic limitation period is two years from the date the claim was discovered. The governing statute is the Limitations Act, 2002. “Discovered” does not always mean the day of the accident or the day a person first noticed pain. It is a legal question based on what the injured person knew, and when they knew it, about the injury, its cause, and the potential responsibility of another person or organization.
In general terms, the discovery analysis asks when a person knew or ought reasonably to have known that:
- an injury, loss, or damage had occurred;
- it was caused or contributed to by an act or omission; and
- the act or omission was that of the person or organization against whom a claim may be made, and a legal proceeding would be an appropriate way to seek a remedy.
The facts matter. A collision may make the date and cause seem obvious, but the nature and seriousness of an injury may not become clear right away. In other cases, a person may know about an injury but not yet understand that another party may be legally responsible. Do not decide on your own that the limitation period began later, or that it has not started. A court may assess discoverability in light of the evidence and the applicable law.
Does the two-year period always start on the accident date?
No. The accident date can be important evidence, but the legal start date is not automatically the same in every case. The date may depend on when the required facts were known or reasonably knowable. For example, symptoms can develop over time, and the connection between an event and a particular injury may not be apparent at first. At the same time, continuing to investigate, treating an injury, or negotiating with an insurer does not automatically suspend a limitation period.
Write down when the accident happened, when symptoms first appeared, when you sought care, and when you learned information about the possible cause. Keep records that may help explain the timeline. These details do not decide the legal issue by themselves, but they can help a lawyer assess it.
Is there also an ultimate deadline?
Ontario’s Limitations Act also contains an ultimate limitation period, generally 15 years from the act or omission on which a claim is based, subject to statutory rules and exceptions. It is different from the basic two-year period. The existence of a longer outside period does not mean an injured person can wait 15 years to start a claim. The basic limitation period may expire much earlier, and other laws can set different rules.
Personal Injury Limitation Period Ontario: When Can It Be Paused or Extended?
Some situations can affect how a limitation period is calculated. They are exceptions that depend on the person’s circumstances and the governing law, not automatic extra time. If any of these situations may apply, obtain advice promptly rather than relying on an assumption that the clock is paused.
What if the injured person is a minor?
Special rules may apply when the person with the claim is under 18. In some circumstances, the basic limitation period does not run while a person is a minor, but an appointed litigation guardian or other legal details can affect the analysis. A parent or caregiver should not assume that every deadline is postponed until the child turns 18. Keep records and ask a lawyer to review the particular facts.
What if the person is not mentally capable of managing the claim?
The Limitations Act has rules that may suspend a limitation period during a person’s incapacity, subject to qualifications, including whether a litigation guardian is acting for them. Capacity is a legal issue and is not established merely because someone has a serious diagnosis, needs assistance, or is unable to work. Medical records and the person’s ability to understand and manage the proceeding may be relevant. Family members should seek legal advice about who can act and what steps are needed.
Can an insurer’s discussions or an informal promise give you more time?
Do not count on it. An adjuster’s ongoing review, requests for records, settlement discussions, or a statement that the insurer is “looking into it” may not pause the deadline for starting a lawsuit or an application. An agreement about a limitation period may have strict legal requirements. Get any proposed agreement reviewed by a lawyer, and keep track of deadlines while negotiations continue.
There can also be special notice requirements for claims involving particular defendants or events. For example, a claim arising from an incident on certain public property may involve a separate notice deadline. The applicable period and exceptions depend on the type of claim and the law in force. If a municipality, public authority, or other special defendant may be involved, get advice immediately; do not wait for the usual two-year period.
Accident Benefits and Tort Claims: Why Are Their Deadlines Different?
After a motor vehicle accident in Ontario, a person may have rights under their own automobile insurance policy even if they did not cause the collision. These statutory accident benefits, commonly called SABS benefits, are different from a tort claim seeking compensation from another party. The benefits process has its own notice, application, and dispute timelines. A tort limitation period does not replace those deadlines, and meeting a benefit deadline does not necessarily protect a tort claim.
| Issue | Accident-benefit claim | Tort injury claim |
|---|---|---|
| Who is the claim generally made against? | An insurer under the applicable automobile policy and statutory scheme. | A person or organization alleged to have caused or contributed to the injury. |
| What is being sought? | Benefits available under the policy and statutory rules, depending on eligibility and evidence. | Legal compensation for losses caused by another party’s alleged fault, if the legal requirements are met. |
| What deadlines should be checked? | Notice, application, treatment-plan, insurer-response, and dispute deadlines may apply. Check the current forms, legislation, and correspondence. | The basic limitation period is often two years from discovery, with possible exceptions and other requirements. |
| Does action on this track preserve the other? | No. Filing for benefits does not automatically start or preserve a tort lawsuit. | No. Starting a tort claim does not automatically satisfy accident-benefit requirements. |
For an accident-benefit dispute, read insurer letters carefully and note the date and reason for any denial or reduction. There may be a limited time to challenge a decision through the Licence Appeal Tribunal, Automobile Accident Benefits Service (LAT-AABS), and the applicable deadline should be confirmed from the current rules and the notice you received. Do not assume that a phone call or internal review request preserves the right to dispute a decision.
Hoffman Law’s page about accident benefits (SABS) in Ontario explains the firm’s work in this area. If you are also considering a claim for losses caused by another party, keep that separate question in view. A lawyer can help identify which processes may apply and which dates must be protected.
What Should You Do Today if You May Be Near a Deadline?
If you think time may be running short, take practical steps now. You do not need to have every medical answer or piece of evidence in hand before asking about the deadline. Waiting for a complete recovery or for an insurer to make a final decision can leave less time to act.
- Make a date list. Record the accident or incident date, when symptoms started, when you sought medical care, insurer notices and decisions, and any important conversations. Mark dates you are not sure about as approximate.
- Keep the documents. Save emails, letters, claim forms, medical records, photographs, witness details, and proof of expenses. Keep the original files where possible, and do not alter photographs or messages.
- Identify every possible claim. Note whether there may be an automobile insurer, an at-fault driver, an employer or property owner, a municipality, or another organization involved. Different claims can have different deadlines.
- Do not wait for negotiations to end. An insurer’s ongoing assessment does not necessarily stop a limitation period. Ask specifically whether a deadline for starting a proceeding needs to be protected.
- Get advice promptly. Bring your date list and documents to a lawyer. Ask which limitation period applies, what event starts it, whether any exception may be relevant, and what immediate procedural steps are needed.
To make that first review more useful, arrange the papers by date rather than trying to decide which items are legally important. Place the incident report, the first medical visit, later diagnoses, photographs, and insurer letters in chronological order.
Add a short note beside each item explaining what happened and who was involved. If a date is uncertain, say so instead of guessing. An approximate month or reference to an appointment can help identify what needs checking.
Keep a copy of the file for yourself and bring the original correspondence or complete digital messages when possible. This preparation will not calculate the deadline, but it can make it easier to spot separate processes, missing information, and any urgent notice or dispute issue that needs individual legal review.
If your injury affects your ability to work, preserve benefit-related records too. Keep the policy, claim forms, medical support, and any denial or termination letter. Disability-benefit disputes have their own policy and legal timelines; information about long-term disability claims and denials may help you identify the separate issues to discuss.
For a claim involving an allegedly unsafe property, preserve photographs, incident reports, witness names, and correspondence with the owner or insurer. A lawyer can assess whether special notice requirements apply. See Hoffman Law’s information about slip and fall claims in Ontario for the relevant service area.

Frequently Asked Questions
Can I start a personal injury claim after two years in Ontario?
Possibly, but it depends on the facts and the applicable law. The two-year period may run from the date a claim was discovered rather than simply from the incident date, and statutory exceptions may affect the calculation. Other notice or procedural deadlines may also apply. Do not assume that you are too late, or that you have extra time, without having the dates reviewed by a lawyer.
Does an insurance claim or settlement discussion stop the lawsuit deadline?
Usually, you should not assume that it does. An insurer’s review, benefit application, internal appeal, or settlement discussion may be separate from starting a lawsuit. Ask for advice about the precise deadline and the formal steps required to preserve each type of claim.
What if I did not know how serious my injury was at first?
The discovery date may be affected by what you knew or reasonably ought to have known about the injury, its cause, and potential responsibility. A later diagnosis can be relevant, but it does not automatically restart or extend the limitation period. Medical and other records can help a lawyer assess the timeline.
Do I need to wait until my treatment is finished before speaking with a lawyer?
No. You can ask about deadlines while treatment continues. A discussion about timing does not require you to know your final prognosis or the full value of a claim. Early advice can help you understand which records to keep and whether a step must be taken before a deadline.
