Catastrophic Impairment in Ontario: Up to $1 Million in Accident Benefits

On this page
If you or someone you love has been badly hurt in a car crash in Ontario, you may have heard the word "catastrophic" used by a doctor, an insurer, or a lawyer. It is not just a scary word. In Ontario auto insurance, catastrophic impairment is a precise legal category. It is reserved for the most serious injuries, and meeting it changes everything about the help you can receive.
In Ontario, a catastrophic impairment designation can raise your combined limit for medical, rehabilitation, and attendant care from $65,000 all the way to $1,000,000. It can raise the monthly amount available for a personal support worker from $3,000 to $6,000. And it can remove the usual time limit on your benefits, so that support can continue for the rest of your life instead of stopping after five years. For a person facing a lifetime of care, this is the difference between running out of funding and being protected for the long haul.
This guide explains catastrophic impairment in plain words. It covers what the category means, the medical situations that can meet it, why the money jumps so much, how the decision is actually made, what to do if the insurer says no, and how a catastrophic injury also drives a large lawsuit against the driver who caused the crash. The rules come from the Statutory Accident Benefits Schedule, known as the SABS, which is Ontario Regulation 34/10. The catastrophic definition sits in section 3.1, and the process for proving it sits in section 45.

What is a catastrophic impairment in Ontario?
A catastrophic impairment is the most serious level of injury recognized in the Ontario accident benefits system. Think of it as the top rung of a ladder. On the bottom rung is a minor injury, such as a simple sprain or strain, with a treatment limit of only $3,500. On the middle rung is a serious injury that is not minor and not catastrophic, with a combined limit of $65,000. On the top rung is catastrophic impairment, with a combined limit of $1,000,000 and no time cap.
The word "impairment" has a specific meaning here. The SABS defines an impairment as a loss or abnormality of a psychological, physiological, or anatomical structure or function. In everyday terms, it is a lasting loss of the way your body or mind works. A catastrophic impairment is one of a defined set of the very worst of those losses.
It helps to understand that catastrophic impairment is a legal test, not a feeling. A person can be in terrible pain, unable to work, and deeply changed by a crash, and still not meet the legal definition. On the other hand, some people meet the definition even though, to a stranger, they might look like they are coping. The category is defined by specific medical criteria and rating tools, and doctors apply detailed guides to measure them. The question is never simply "is this bad." The question is "does this injury meet one of the listed criteria in section 3.1 of the SABS."
The category was set up this way on purpose. Because the money attached to a catastrophic designation is so large, the law draws a clear line and tells assessors exactly how to measure whether an injury crosses it. That precision protects seriously injured people, because it gives them a defined path to prove their case. It also means the fight often turns on medical measurement and expert reports rather than on general sympathy.
Why does a catastrophic designation matter so much?
The plain answer is money and time. A catastrophic designation unlocks far more funding, and it removes the clock. Here is how the numbers work under the SABS.
For a serious injury that is not minor and not catastrophic, section 18 of the SABS sets a combined limit of $65,000 for medical, rehabilitation, and attendant care benefits. That $65,000 is a single shared pot. It covers all three types of help together, not $65,000 for each. For a badly hurt person, that pot can empty fast. A single surgery, months of physiotherapy, psychological treatment, assistive devices, and some in home help can burn through $65,000 well before the person has recovered.
For a catastrophic impairment, that same combined limit jumps to $1,000,000, more than fifteen times the non catastrophic amount. It is meant to fund the reality of a lifelong serious injury, where care, therapy, equipment, and support add up year after year.
Attendant care is treated the same way. Attendant care benefits pay for a person who helps you with daily living, such as bathing, dressing, eating, and moving around. Under section 19, the monthly limit for attendant care is $3,000 for a non catastrophic injury. For a catastrophic impairment, that monthly limit rises to $6,000. Over months and years, that difference is enormous.
Then there is time. Under section 20, medical, rehabilitation, and attendant care benefits for most non catastrophic injuries stop 260 weeks after the accident, which is five years. If the injured person was under 18 at the time, the benefits can run until age 28 instead. But for a catastrophic impairment, section 20 removes that time limit entirely. Catastrophic benefits can continue for life, as long as the treatment or care remains reasonable and necessary. For someone who will need support for decades, this is often the single most important effect of the designation.
There are other advantages too. A catastrophic designation lifts several smaller time limits that otherwise apply, such as the limit on housekeeping and on visitor expenses, and it can open the door to a professional case manager to help coordinate care. It also changes the rules on transportation costs, so that mileage to appointments is covered from the first kilometre rather than only after the first fifty kilometres. Each of these on its own is modest. Together, they reflect a system designed to wrap far more support around the most seriously injured people.
One point to keep in mind. The $1,000,000 catastrophic limit covers medical, rehabilitation, and attendant care. It does not include income replacement or other benefits, which are handled separately. Under the reform that took effect on July 1, 2026, income replacement and most other benefits became optional coverage that has to be purchased in advance, while medical, rehabilitation, and attendant care coverage stayed mandatory in every policy. You can read about that broader change in our guide to the 2026 Ontario accident benefits overhaul, and about the income side in our guide to income replacement benefits.
How do the non catastrophic and catastrophic limits compare?
Sometimes a side by side view makes the stakes clear. The table below shows the main differences between a serious non catastrophic injury and a catastrophic impairment under the current SABS.
| Feature | Non catastrophic (serious) | Catastrophic |
|---|---|---|
| Combined medical, rehabilitation, and attendant care limit | $65,000 | $1,000,000 |
| Monthly attendant care limit | $3,000 | $6,000 |
| Time limit on benefits | Ends 260 weeks (5 years) after the accident | No time limit, can continue for life |
| Housekeeping and visitor time limits | Apply | Lifted |
| Professional case manager | Generally not funded | Available |
| Optional top up available | Yes, higher medical and rehabilitation coverage | Yes, up to a further $1,000,000 |
Read the table with one idea in mind. Every row moves in the same direction. A catastrophic designation does not just add a little. It multiplies the support available and takes the clock off it. That is why the fight over whether an injury is catastrophic is often the most important battle in the whole claim.
What are the categories of catastrophic impairment?
Section 3.1 of the SABS lists the situations that count as catastrophic for accidents on or after June 1, 2016. There are several categories. Below, each one is explained in plain language. Keep in mind that the actual criteria are medical and detailed, and that qualified doctors apply recognized rating guides to decide whether they are met. This is a readable overview, not the full legal text.
Paraplegia or tetraplegia from a spinal cord injury
The first category covers serious paralysis caused by a spinal cord injury. Paraplegia means the loss of movement and feeling in the legs and lower body. Tetraplegia, also called quadriplegia, means the loss of movement and feeling in both arms and both legs. These are life changing injuries that usually leave a person using a wheelchair and needing help with many daily tasks.
The SABS does not simply say "paralysis." It ties the test to a standard medical grading system called the ASIA Impairment Scale, which classifies how complete or incomplete a spinal cord injury is. Depending on the grade, the rules also look at how well the person can move indoors over a short distance, whether they need help managing bladder function through catheters or surgery, and whether they have lost voluntary control of bowel function. These measurements let assessors separate the most serious spinal cord injuries from less severe ones. If you are dealing with this kind of injury, our spinal cord injuries page explains how these claims work.
Severe loss of walking ability, loss of the use of an arm, or an amputation
The second category covers severe and permanent loss of movement in a leg or arm, or an amputation. It is met in several ways. One is the amputation of a leg below the knee or higher up. Another is the amputation of an arm, or another injury that causes the total and permanent loss of the use of an arm. A third is a severe and permanent change to the structure and function of one or both legs that badly limits the ability to walk indoors, again measured on a standard mobility scale over a short distance.
The point of this category is that you do not always need a formal amputation to qualify. A leg that is so damaged that it can no longer support normal indoor walking can meet the test through the mobility measurement, even if it is still physically attached. This matters for people with crush injuries, severe fractures that did not heal properly, or serious nerve damage.
Total loss of vision in both eyes
The third category is the loss of vision in both eyes. Even with glasses, contact lenses, or medication, the vision in both eyes has to be 20/200 or worse, or the field of vision in both eyes has to be narrowed to 20 degrees or less. In addition, the vision loss has to come from a physical cause connected to the accident, not from a non physical or psychological cause. This category captures people left legally blind by a crash, whether from direct eye trauma or from a brain injury that damaged the visual pathways.
A traumatic brain injury in an adult
The fourth category covers a traumatic brain injury, or TBI, in a person who was 18 or older at the time of the accident. A traumatic brain injury is damage to the brain caused by an outside force, such as the head striking the inside of a vehicle. This category has two parts that both have to be present.
First, there has to be objective proof of brain injury on imaging. A CT scan, an MRI, or another medically recognized brain scan has to show damage inside the skull that resulted from the accident, such as bleeding, bruising, swelling, or a shift in the brain. This is the physical fingerprint of the injury.
Second, the injury has to lead to a serious lasting outcome, measured against a recognized tool called the Glasgow Outcome Scale Extended, at set points in time after the accident. In simple terms, the rules look at whether the person remains in a vegetative state one month or more after the crash, remains in severe disability six months or more after, or remains in what the scale calls lower moderate disability one year or more after. The longer a serious deficit lasts, the more clearly it meets the test. To learn more about how these injuries are valued, see our guide to what a traumatic brain injury is worth and our brain injuries page.
It is worth flagging that not every brain injury is catastrophic. Many people suffer a concussion, which is a mild traumatic brain injury, and recover over weeks or months without meeting this category. Others have lasting symptoms that are serious but do not cross the catastrophic line. If you are trying to understand where a head injury falls, our guide on concussions after a car accident walks through the range.
A traumatic brain injury in a child under 18
The fifth category is a separate, more protective set of rules for children who were under 18 at the time of the accident. Young children are treated differently because their brains are still developing and because the standard adult scales do not fit them well. The child version looks at whether the child was admitted to certain hospitals or to a pediatric rehabilitation program with positive brain imaging. It also looks at the child's level of neurological function at one month, six months, and nine months after the accident, measured on a scale built for childhood head injury.
There is an extra layer for the youngest and most serious cases. Under section 45.1, a child who meets certain of these hospital admission criteria is deemed to have a catastrophic impairment right away, without waiting for the usual assessment steps. The law does this so that a seriously brain injured child and their family can access the higher benefits quickly, at the exact moment they are needed most.
A 55 percent or more whole person impairment
The sixth category does not depend on any single named injury. Instead, it adds up the effect of a person's physical injuries into one overall score. Using the American Medical Association Guides to the Evaluation of Permanent Impairment, doctors rate each impairment and combine them into a single figure for the "whole person." If that figure reaches 55 percent or more, the person meets this category.
This route matters for people with multiple serious injuries that are each significant but that might not individually fit one of the other categories. Think of someone with a badly damaged pelvis, a serious spine injury, an internal organ injury, and chronic pain. No single one of those might be listed as catastrophic on its own, but together they can add up to 55 percent or more of the whole person. The rating is technical and is done by qualified assessors who follow the AMA Guides closely.
A combined mental and physical impairment reaching 55 percent
The seventh category is similar, but it allows a mental or behavioural impairment to be combined with physical impairments. A mental or behavioural condition, such as a severe psychiatric response to the trauma, is rated under a specific chapter of the AMA Guides and then combined with the physical impairment score. If the combined figure reaches 55 percent or more of the whole person, the person meets this category. This route recognizes that the harm from a serious crash is often both physical and psychological, and that the two together can be catastrophic even when neither alone would be.
A marked or extreme mental or behavioural impairment
The eighth category focuses purely on mental and behavioural harm. It is met in one of two ways, in each case because of a mental or behavioural disorder. The first is a class 4 impairment, described as "marked," in three or more areas of function, where the impairment precludes useful functioning. The second is a class 5 impairment, described as "extreme," in one or more areas of function, again where the impairment precludes useful functioning. The "areas of function" are broad parts of daily life, such as the ability to carry on daily activities, to get along with others socially, to concentrate and keep pace, and to adapt to the demands of work or stressful situations.
In plain terms, this category is for people whose psychological injuries are so severe that they can no longer function usefully in major areas of their life. It often applies to people with severe depression, severe post traumatic stress, or a serious anxiety disorder that followed the crash. Because psychological injuries are harder to measure than a broken bone, these claims lean heavily on detailed assessments by psychiatrists and psychologists, and they are among the most hotly contested.
A note on how the categories are read
Two things are worth remembering across all of these categories. First, an injury only needs to meet one category to be catastrophic. You do not have to satisfy several. Second, the criteria are medical and technical, and the exact wording in section 3.1 is what counts, not this summary. That is why a proper assessment by qualified experts is so important. The categories are a map of the possible routes, and a good legal and medical team will find the route that fits the injury.
How is catastrophic impairment decided?
The decision is a process, not a single moment. Section 45 of the SABS sets out how it works, and understanding the steps helps you avoid missteps that can cost time and money.
It starts with an application. The injured person, usually with the help of a lawyer and a treatment team, applies to the insurer for a determination of whether the impairment is catastrophic. This is not the same as an ordinary treatment request. It is a formal request for a designation, and it is supported by detailed assessment reports.
Those assessments have to be done by the right professionals. Under section 45, an assessment for catastrophic impairment has to be conducted by a physician, who may be assisted by other regulated health professionals such as occupational therapists, psychologists, and nurses, depending on the injury. There is one special rule. If the impairment is a traumatic brain injury only, the assessment may be led by a neuropsychologist rather than a physician. In practice, a catastrophic assessment often involves a team, because these injuries touch many parts of a person's body and life, and each area needs its own expert.
Once the completed application is submitted, the insurer has a defined window to respond. Within 10 business days of receiving the signed application, the insurer has to give the injured person a notice that either accepts the impairment as catastrophic or rejects it. If it rejects the claim, the notice has to give the medical and other reasons. The insurer can also require the person to attend its own examination under section 44 before deciding, which is common in disputed cases. After that examination, there is a further short window for the insurer to respond.
There is a helpful protection built into this process. If the person applies within 260 weeks of the accident and was already receiving attendant care benefits, section 45 says the insurer has to keep paying attendant care during the period before it makes its decision, and to pay it at the higher catastrophic rate in the meantime. This stops a vulnerable person from losing their care while the paperwork is being sorted out.
One more practical point. The cost of the catastrophic assessments themselves is generally recoverable. Section 25 of the SABS provides that reasonable fees for preparing a catastrophic impairment application, including the assessments and examinations needed for it, are payable. So the detailed reports that prove a catastrophic case do not have to come out of the injured person's pocket. This matters, because a full catastrophic assessment can be extensive.
When is the right time to apply for a catastrophic designation?
Timing is one of the trickiest parts of a catastrophic claim, and getting it wrong can hurt a case. The core idea is that some injuries are catastrophic from the very start, while others become catastrophic only over time as it becomes clear that the person is not going to recover.
Some categories can be met early. A high level spinal cord injury with paralysis, a leg amputation, or the loss of vision in both eyes can be obvious in the days or weeks after the crash. For a seriously brain injured child, the deeming rule under section 45.1 can apply almost immediately. In these cases, there is no reason to wait, and an early application can unlock the higher benefits when the family needs them most.
Other categories are built to require the passage of time. The 55 percent whole person route, the combined mental and physical route, and the marked or extreme mental impairment route generally cannot be established until one of two things happens. Either two years have passed since the accident, or a physician assesses the person at least three months after the accident and concludes that the impairment already reaches the catastrophic level and is unlikely to improve below it. For the psychological category, a physician can instead state in writing that the condition is unlikely to improve to less than a marked impairment. These waiting rules exist because impairment that depends on an overall rating or on a psychiatric outcome needs time to stabilize. A person's condition six weeks after a crash may look very different a year later, in either direction.
This creates a genuine judgment call. Apply too early on a rating based category, and the assessment may understate the injury because the person is still in the middle of treatment and recovery. Wait too long, and the person may go without the higher benefits during the very period they need them. The sweet spot is usually when the injuries have stabilized enough that a qualified assessor can give a firm, defensible opinion. A lawyer who handles these cases will watch the medical picture and time the application to give it the best chance while protecting access to care in the meantime.
What happens if the insurer says no?
Disputes over catastrophic impairment are common. Because the designation is worth so much, insurers frequently require their own examinations and often disagree with the injured person's assessors. A denial is not the end of the road. It is the start of a dispute that you can win.
If the insurer decides an impairment is not catastrophic, or denies benefits that flow from it, the dispute goes to the Licence Appeal Tribunal, usually called the LAT. The LAT is an independent tribunal that decides accident benefit disputes in Ontario. An adjudicator hears the evidence from both sides, including the competing expert reports, and decides whether the legal test in section 3.1 is met. Many catastrophic cases are decided this way, and the injured person often wins when the medical evidence is strong and well presented. Our guide on what to do when accident benefits are denied at the LAT explains the process step by step.
The evidence at these hearings is detailed. Both sides bring assessment reports, and the assessors themselves may testify and be cross examined. The adjudicator weighs the credibility and thoroughness of each expert. This is why the quality of the assessment matters so much. A rushed or thin report can sink an otherwise strong case, while a careful, well documented assessment can carry the day. Decisions of the LAT are published and can be read on CanLII, the free legal database, which lets lawyers see how similar cases have been decided.
It also matters that you present a consistent picture. Insurers often use surveillance and social media to test whether a person's reported limitations match their daily life. If an assessment says a person is severely isolated, but video shows them socializing regularly, an adjudicator may prefer the more moderate view. Honesty and consistency are not just ethical duties. They are practical necessities in a contested catastrophic claim.
Real Ontario examples of catastrophic disputes
To make this concrete, here are several real Ontario accident benefit decisions from 2026. Every one of them is a real dispute about the statutory accident benefits described in this guide. Read together, they show how the catastrophic question is actually fought, won, and lost, and why the quality of the evidence and the timing of each step matter so much. These are other people's cases and not legal advice about yours, but they are a useful window into how the system really works.
A case where the insurer conceded catastrophic impairment: Padernal v. Security National
In Padernal v. Security National Insurance Company, 2026 CanLII 68582 (ON LAT), the applicant was a pedestrian who was struck on his left side by a vehicle while crossing at a city intersection in May 2022. The force sent him onto the hood of the car and then onto the pavement, and the driver fled the scene. At the hospital he was found to have no fractures and was diagnosed with soft tissue injuries, given pain medication, and sent home. Over the following months he developed numbness spreading down his arms, worsening pain, anxiety, and trouble sleeping.
He first applied for a catastrophic determination through the whole person impairment route. The insurer sent him to its own panel of examinations, which came back at a combined whole person rating of 25 percent, far below the 55 percent threshold, so the insurer denied the claim. He applied a second time, now relying on the physical whole person route, the combined mental and physical route, and the mental and behavioural route. The insurer again arranged its own examinations, and again its assessors concluded he was not catastrophically impaired.
Then, on the last business day before the hearing, the insurer reversed course. After reviewing an updated set of medical records, it wrote to the applicant and accepted that his impairments met the catastrophic test under the mental and behavioural category. That concession resolved the central issue. The applicant was catastrophically impaired, and the higher benefit limits applied.
But the case did not end there, and the rest of it is a caution. The applicant also asked the Tribunal for three more things: the unpaid balance of his catastrophic assessment costs, which ran above the funding limit; a special award as a penalty for how the insurer had handled the file; and his legal costs. The Tribunal refused all three. On the assessment costs, it held that the Schedule caps each assessment or examination and its report at a set amount. Extra line items such as collecting and analyzing data, reviewing documents, and a separate second psychiatric report were either part of the capped assessment or not shown to be reasonable and necessary. On the award, it found that a late change of position, without evidence that the insurer had deliberately withheld records or hidden its reversal, did not meet the demanding standard of conduct that is excessive, imprudent, stubborn, inflexible, unyielding, or immoderate. On costs, it found that resolving an issue shortly before a hearing is reasonable behaviour, not misconduct. So the applicant secured the thing that mattered most, the catastrophic designation and its funding, yet recovered none of the extra amounts he sought.
A case where catastrophic status was denied: Escoffery v. Intact
In Escoffery v. Intact Insurance Company, 2026 CanLII 59513 (ON LAT), the applicant sought a catastrophic designation under the mental and behavioural category after a 2018 collision in which she was a passenger in a car that was hit from behind. Her situation had an unusual feature. Years earlier, in a 2012 pedestrian accident, she had suffered a traumatic brain injury and had already been found catastrophically impaired, a claim that settled in 2015. So the question was not whether she was seriously impaired overall. It was whether the 2018 accident, on its own, pushed her mental and behavioural impairment to the catastrophic level.
To meet this category, a person needs at least three marked impairments, or one extreme impairment, across four areas of function: daily living, social functioning, concentration and persistence and pace, and adaptation. Her psychiatrist rated her as markedly impaired in all four areas. The insurer's psychologist rated her as only moderately impaired in all four. The adjudicator sided largely with the insurer's assessor and found she had not shown a marked impairment in either daily living or social functioning. Because she could not reach three marked impairments, the claim failed and the application was dismissed.
The reasons show why the evidence was weighed the way it was. The insurer's psychologist had assessed her in person over half a day and took notes, while her own psychiatrist had assessed her by video, could not say how long the session lasted, and took no notes. The insurer's assessor had personally prepared a detailed review of the medical records, while her psychiatrist had not prepared the medical summary in his own report and could not say who chose the documents. And her psychiatrist had leaned heavily on her own account of a largely unremarkable mental health history before the accident. That account sat awkwardly with the fact that she was still living with serious effects of the earlier brain injury. The adjudicator also found that her reported picture of near total isolation did not match the rest of the evidence. She remained close with her large family, several of whom lived with her or nearby, and she still went outside to her garden and walked her dog. On that record, the more moderate view was preferred.
There is a second, quieter lesson in the decision. Because she was found not catastrophically impaired, the ordinary time limits applied, and her requests for attendant care and for an attendant care assessment failed as well, since they were made after the 260 week cutoff that applies to injuries that are not catastrophic. The designation and the deadline were linked, and losing the first meant losing the rest.
A reconsideration and the limits of a second try: Paesano v. Cooperators
In Paesano v. Cooperators General Insurance Company, 2026 CanLII 71299 (ON LAT), the applicant tried for a second time to be found catastrophically impaired after a 2018 accident. Her first attempt had failed. A 2023 Tribunal decision found she was not catastrophically impaired, and that result was upheld by the Divisional Court on judicial review in 2025, meaning a court reviewed the Tribunal's decision and let it stand. She then filed a fresh catastrophic application. The insurer argued she was barred by the principle of finality, known as res judicata, which stops a party from relitigating an issue that has already been decided. The Tribunal agreed and barred the new application, and she asked for a reconsideration of that ruling. A reconsideration is a request that asks the Tribunal itself to take a second look at its own decision, and it is granted only in narrow situations.
The reconsideration was dismissed. The decision explains that a person can sometimes bring a further catastrophic application, but generally only where there is a genuine material change in their condition. The insurer should not simply be asked to look again at the same condition that has already been decided. Here, the newer medical evidence did not show such a change. Her later psychiatric assessment actually produced a lower whole person score than the earlier report that had already been rejected as inflated, even though it added a marked impairment under a different heading. The Tribunal could not see how a lower rating showed that her condition had materially worsened. Most of her arguments, the reconsideration found, were really attempts to reweigh the same evidence, which is not what a reconsideration is for. Her request, and an added request for costs, were both refused.
The practical lesson is about finality and about evidence. A catastrophic claim is not an open ended series of retries. If the first application fails, a later one usually needs real proof that the condition has grown worse, not just a fresh expert willing to describe the same condition in stronger words. This is one more reason to build the first application carefully, with strong and stable evidence, rather than treating it as a rehearsal.
The two year deadline and the duty to give notice: Sparks v. Primmum
In Sparks v. Primmum Insurance Company, 2026 ONSC 3803, a Divisional Court decision, the dispute grew out of a request to fund a catastrophic impairment assessment. After a 2020 accident, the applicant submitted a plan to pay for the assessments needed to support a catastrophic application. The insurer approved most of it and refused a small balance. It sent her the standard notice telling her she had a right to dispute the refusal and two years to file with the Licence Appeal Tribunal. She filed once, withdrew that application at the start of the hearing, then filed again more than two years after the original refusal. The Tribunal found the second application was out of time, and she appealed.
The Court dismissed the appeal. She had argued that the insurer's notice was defective for two reasons. It did not spell out every later step, all the way up through reconsideration and appeals to the Court of Appeal and the Supreme Court of Canada. And it did not explain the discoverability rule, a principle that can delay the start of a limitation period until the person reasonably knew they had a claim. The Court held that the notice only has to tell the person of the right to dispute the refusal, which means applying to the Tribunal, and does not have to map out the whole chain of appeals that might follow a Tribunal decision. It also held that the notice, which warned in bold that she had two years from the refusal to file or lose the right to dispute, was clear and not misleading, even though in rare cases the discoverability rule can push the start of the limitation period later.
For anyone dealing with a serious injury, the lesson is blunt. The two year limit on disputing a denied benefit is real, and it is triggered by the insurer's notice of refusal. Withdrawing an application without protecting the deadline can be fatal to the claim. Even in a system built as consumer protection, the courts will hold claimants to the clock. The safe course is to treat every denial as starting a strict two year countdown, and to get advice quickly rather than assuming there is room to spare.
What is at stake when an injury is not catastrophic: Zabarain v. Coseco
In Zabarain v. Coseco Insurance Company, 2026 ONSC 3712, another Divisional Court decision, the injured person was a foreign student who was struck by a car while riding his bicycle in 2019. He fractured his hip, needed surgery, and spent eleven days in hospital. His injury was serious, but it was treated as neither minor nor catastrophic, so his medical and rehabilitation benefits were capped at the ordinary $65,000 limit. That limit was paid out and used up, and once it was gone, the insurer was not required to fund further treatment, or even to assess whether later treatment plans were reasonable and necessary. The Court confirmed that outcome on appeal.
The rest of the case was about income replacement benefits and a repayment the insurer claimed after the student returned to work without telling it. Those parts turned on their own facts. But the piece that matters for this guide is the funding cap. This is the very ceiling that a catastrophic designation lifts. Had the same person been found catastrophically impaired, the medical and rehabilitation limit would have been $1,000,000 rather than $65,000, with room to keep funding care for years. The case is a plain illustration of why the catastrophic question is worth fighting. The difference between the two categories is the difference between running out of funding early and having support that can last.
What these cases have in common
Put these decisions side by side and a few themes stand out. The catastrophic question is decided on careful measurement and credible, consistent evidence, not on how upsetting the injury looks. Insurers do sometimes concede when the proof becomes strong, as in Padernal, but a concession on the designation does not hand over every extra dollar an applicant asks for. When the numbers fall short of a threshold, or the reported limitations do not match the rest of the evidence, the claim can fail, as in Escoffery. A first loss tends to stick, because finality and res judicata make a second attempt hard without proof of real change, as in Paesano. Deadlines are strict and are set running by the insurer's notice of refusal, as in Sparks. And the whole fight matters because the alternative, staying in the category that is not catastrophic, means a hard funding ceiling that can run out, as Zabarain shows. Strong assessments, honest and consistent reporting, and careful timing are what carry these cases.
What does a catastrophic injury mean for a lawsuit against the driver?
Accident benefits are only one of the two tracks available after a serious crash in Ontario. The other track is a lawsuit, called a tort claim, against the driver who caused the crash. For catastrophic injuries, this lawsuit is usually where the largest part of the total recovery comes from. It is important to understand both tracks, because they work together.
The lawsuit can claim things that accident benefits do not fully cover. There are three main categories.
The first is pain and suffering, which the law calls non pecuniary damages. This is money for the physical pain, the emotional suffering, and the loss of enjoyment of life caused by the injury. In the very worst cases, such as severe brain injuries and high level paralysis, this amount can approach the ceiling that the Supreme Court of Canada set for pain and suffering in a set of cases known as the trilogy. That ceiling rises slowly with inflation. As of 2025 it sits at roughly $465,000 to $470,000. The exact current figure should be confirmed by your lawyer, because it moves each year. Catastrophic injuries are the kind of cases that reach the upper part of this range.
The second is lost income. A catastrophic injury often ends a person's ability to work, sometimes for the rest of their life. The lawsuit can claim the income already lost and the full value of future earnings the person will never be able to make. For a young person with a long career ahead of them, this figure can be very large.
The third is the cost of future care. This is often the biggest number in a catastrophic case. It covers the lifetime cost of attendant care, therapy, medication, equipment, home modifications, and everything else the person will need. Experts prepare a detailed report, sometimes called a future care cost report, that prices out these needs over the person's expected lifetime. Because catastrophic injuries require care for decades, these figures can reach into the millions.
To see how all of these pieces come together into a single number, read our guide on how a car accident settlement is calculated. It walks through each category and how lawyers build a claim.
There is one more piece of good news for catastrophic cases on the tort side. Ontario applies a deductible to pain and suffering awards, which for 2026 is $47,913.01. But that deductible disappears entirely once the pain and suffering award reaches a threshold, which for 2026 is $159,708.71. Because catastrophic injuries almost always produce pain and suffering awards well above that threshold, the deductible usually does not reduce the award at all. The rules on the threshold and the deductible come from section 267.5 of the Insurance Act, with the annual figures published by FSRA.
How do the two tracks work together in a catastrophic case?
It helps to see how accident benefits and the lawsuit fit together, because a well run catastrophic claim uses both at once.
Accident benefits come first and fast. They come from the injured person's own insurer, no matter who caused the crash, and they are meant to fund treatment and care right away. In a catastrophic case, the $1,000,000 combined pot for medical, rehabilitation, and attendant care and the $6,000 monthly attendant care limit start funding care while the person is still in hospital and rehabilitation. This is the money that keeps care flowing in the early years, long before any lawsuit is resolved.
The lawsuit comes later and is larger, but slower. A serious lawsuit can take years to resolve, because the full extent of a catastrophic injury and its lifelong costs cannot be known until the person's condition has stabilized and the future care needs are properly assessed. The lawsuit picks up what accident benefits do not cover, including pain and suffering, the full value of lost income, and the future care costs that exceed the accident benefit limits.
The two tracks are coordinated so that a person is not paid twice for the same loss. In general, amounts received through accident benefits for a type of loss are taken into account in the lawsuit for that same loss, so the total is fair rather than doubled. A lawyer manages this coordination, making sure the accident benefit claim is maximized early while the lawsuit is built for the long term. Trying to do this alone, while also recovering from a catastrophic injury, is extremely difficult, which is one of the strongest reasons to get help.
Can you buy extra coverage above the standard catastrophic limit?
Yes. The standard mandatory catastrophic limit is $1,000,000 for medical, rehabilitation, and attendant care. But the SABS also allows optional coverage that can raise this substantially, and it is worth knowing about, both when buying insurance and when reviewing a claim.
Under section 28 of the SABS, a person can buy optional coverage that raises the catastrophic medical, rehabilitation, and attendant care limit to $2,000,000, double the standard amount. There is also an optional catastrophic impairment benefit that can add a further $1,000,000 on top of the mandatory limit. For a person facing a lifetime of care, this extra coverage can make a real difference, because even $1,000,000 can be used up over many years of intensive support.
There are other optional add ons too. An optional dependant care benefit can help with the cost of caring for a person's dependants while they recover. An optional indexation benefit raises certain benefit amounts each year with inflation, so their value does not shrink over a long recovery. These options have to be purchased before the accident, not after, which is why it is worth reviewing your own policy now rather than waiting.
If you are reading this after a crash, do not assume you only have the standard limit. Part of a lawyer's job is to pull the actual policy and check whether any optional coverage was purchased, because that extra coverage can be easy to overlook and very valuable. To understand how these optional benefits fit into the bigger 2026 picture, see our guide to the 2026 accident benefits changes.
What might a catastrophic claim look like from start to finish?
It can help to walk through how a catastrophic claim tends to unfold. The following is an illustrative example, not a real client and not legal advice, but it shows the shape of the process and how the pieces connect over time.
Imagine a person in their thirties who is struck by another vehicle and suffers a serious brain injury along with several broken bones. In the first days, the priority is survival and stabilization in hospital. A family member reports the crash to the injured person's own auto insurer and asks for the accident benefit application forms. Because the injury is clearly serious, attendant care and medical benefits begin to flow under the standard limits while the bigger questions are still open.
Over the first few months, the treatment team documents the brain injury with imaging and tracks the person's recovery. As the picture stabilizes, a specialized legal and medical team assembles the catastrophic assessment. Because this is a brain injury, a neuropsychologist can lead that part of the work, supported by other experts who assess physical function, mental health, and the person's ability to manage daily life. The assessments are thorough, and their cost is generally covered as part of the application.
The catastrophic application then goes to the insurer under section 45. The insurer may accept it, or it may require its own examination first and then decide. If it accepts the catastrophic designation, the combined limit jumps to $1,000,000, the monthly attendant care limit rises to $6,000, and the time cap disappears. If it denies the designation, the dispute heads to the Licence Appeal Tribunal, where an adjudicator weighs the competing reports.
Running alongside all of this is the lawsuit against the driver who caused the crash. That claim is built more slowly, because the full lifetime cost of care and the long term loss of income cannot be measured until the injury has stabilized. Years later, the lawsuit resolves for a much larger sum that reflects pain and suffering, lost earnings, and a lifetime of future care. The accident benefits carried the person through the early years, and the lawsuit provides for the decades ahead. That is the two track system working the way it is meant to.
What are the most common mistakes in catastrophic claims?
Lawyers who handle these cases see the same avoidable errors again and again. Being aware of them can protect a claim.
The first mistake is treating a catastrophic assessment like an ordinary treatment request. A catastrophic determination is a formal, evidence heavy process. Skimping on the assessments, or using assessors who do not specialize in catastrophic work, can produce a thin report that the insurer easily rejects. The assessment is the foundation of the whole claim, and it deserves care.
The second mistake is bad timing. Applying too early on a rating based category can lock in an assessment done before the injury has stabilized, understating the true impairment. Waiting too long can leave the person without the higher benefits during a critical period. The right timing is a judgment call that benefits from experience.
The third mistake is inconsistency. Because insurers use examinations, surveillance, and social media to test a claim, a person whose reported limitations do not match their daily life can lose credibility. The lesson is not to exaggerate and not to minimize, but to be accurate and consistent, and to let the medical evidence speak.
The fourth mistake is going it alone. Catastrophic claims involve competing experts, strict processes, tight timelines, and enormous sums. Insurers bring their own doctors and lawyers to these fights. An injured person and their family, already stretched thin by the injury itself, are at a serious disadvantage without their own experienced team.
The fifth mistake is missing the lawsuit. Some people focus so hard on the accident benefit side that they overlook the tort claim against the at fault driver, which is usually where the largest recovery lies. Both tracks matter, and both have deadlines. In Ontario you generally have two years to start a lawsuit, though catastrophic cases involving young people or complex facts can have different timing, so early advice is essential.
What practical steps should a family take after a catastrophic injury?
If a loved one has been catastrophically injured, the days and weeks after the crash are overwhelming. Here is a practical sequence that helps protect both their recovery and their claim.
Focus first on medical care and stabilization. The immediate priority is always the injured person's health. The medical record that builds during this time is also the backbone of the later claim, so make sure treatment is documented and follow the medical team's guidance.
Report the accident to the person's own auto insurer promptly and ask for the accident benefit application package. There are strict, short deadlines to return these forms, and starting the accident benefit file early gets care funded sooner. If the person cannot handle this themselves, a family member or a lawyer can help.
Keep every record and receipt. Save medical reports, prescriptions, receipts for any expenses connected to the injury, and notes about how the person is functioning day to day. This evidence supports both the catastrophic determination and the lawsuit.
Be careful with the other driver's insurer. Do not give a recorded statement to the at fault driver's insurance company, and do not accept any quick settlement, before understanding what the claim is truly worth. Catastrophic claims are worth far more than an early lowball offer.
Get specialized legal help early. Catastrophic claims are among the most complex in personal injury law. The assessments are detailed, the timing is delicate, the disputes are common, and the stakes reach into the millions. Getting a lawyer who handles catastrophic cases involved early, before key decisions are made, can protect the claim in ways that are hard to fix later. Most personal injury lawyers, including our team, work on a contingency fee, which means there are no legal fees unless the claim succeeds.

Key terms explained
Catastrophic impairment. The most serious legal category of injury in Ontario accident benefits, defined in section 3.1 of the SABS. It unlocks a $1,000,000 combined limit for medical, rehabilitation, and attendant care, a $6,000 monthly attendant care limit, and benefits with no time cap.
Impairment. A lasting loss or abnormality of a psychological, physiological, or anatomical structure or function. In plain words, a lasting loss in the way the body or mind works.
Attendant care benefit. Payment for a person who helps with daily living, such as bathing, dressing, and moving around. The monthly limit is $3,000 for a non catastrophic injury and $6,000 for a catastrophic one.
Whole person impairment. An overall percentage score that combines a person's impairments using the American Medical Association Guides. A score of 55 percent or more can meet the catastrophic test.
ASIA Impairment Scale. A standard medical grading of spinal cord injury that the SABS uses to help decide whether paralysis is catastrophic.
Glasgow Outcome Scale. A recognized tool used to measure the lasting outcome of a brain injury at set times after an accident, used in the adult brain injury category.
Licence Appeal Tribunal. Often called the LAT. The independent Ontario tribunal that decides accident benefit disputes, including whether an impairment is catastrophic.
Section 44 examination. An examination the insurer can require the injured person to attend as part of deciding a catastrophic claim.
Special award. An extra amount the LAT can order against an insurer that has unreasonably withheld or delayed benefits. It is not automatic and has to be justified.
Tort claim. The lawsuit against the driver who caused the crash, separate from accident benefits, which claims pain and suffering, lost income, and future care.
Trilogy cap. The ceiling the Supreme Court of Canada set on pain and suffering awards, which rises with inflation and sits at roughly $465,000 to $470,000 as of 2025. The exact current figure should be confirmed, because it moves each year.
Contingency fee. A fee arrangement where the lawyer is paid a percentage of the recovery, so the client pays no legal fees unless the claim succeeds.
