Brain Injury Settlement Ontario: Settlements in Ontario

Brain injury settlements in Ontario do not have a fixed average amount. The value of a claim depends on factors such as the severity of the injury, medical documentation, loss of work, future treatment and rehabilitation needs, available insurance coverage, liability, and how the injury affects daily life, independence, and quality of life.

An injury to the brain can affect virtually all aspects of a person’s life. A person may have headaches, memory loss, problems focusing, mood or behavioural changes, mobility problems, inability to work and may require long-term medical treatment and/or rehabilitation depending on the severity of the injury.

If the brain injury was caused by a car accident, slip and fall accident, and/or another person’s negligence, the injured party may be eligible to receive compensation. For injured people in Ontario and their families who are trying to understand their legal rights and potential compensation, calculating the worth of brain injury settlements in Ontario is seldom easy.

The consequences of a traumatic brain injury may not be seen right away, whereas the effects of an injury like a fracture will be known within a few days. Therefore, a just settlement might require consideration for prognosis, future medical requirements, lost earning potential, independence and quality of life, in addition to present losses.

Knowing the factors that can impact a brain injury claim can help injured people and their families make decisions before taking a settlement. This page explains how brain injuries affect a claim, what goes into calculating compensation, and how legal support can help with a brain injury claim in Ontario.

What Is the Average Settlement for a Traumatic Brain Injury Claim in Ontario?

Unfortunately, there is no one-size-fits-all (100%) average settlement for a traumatic brain injury claim in Ontario. The amount of a brain injury claim is dependent on the extent of the injury, medical documentation, loss of work, future medical care needs, insurance coverage, liability and the impact the injury has on the individual’s daily life.

A mild concussion that heals after a few months will typically result in very different losses from a moderate or severe traumatic brain injury that would impact a person’s ability to work or live independently.

As a result, it can be confusing to compare a claim to an advertised “average TBI settlement”.

The value of settlement can differ significantly for people who have a different experience:

• Mild Traumatic Brain Injury (mTBI) or concussion
• Persistent post-concussion symptoms
• Brain changes (cognitive or memory impairment)
• Physical or neural impairments
• Changing psychological/behavioural state (e.g. depression)
• Permanent disability
• Reduced earning capacity
• Heavy future health & rehabilitation costs
• Unmet need for personal care or help with activities of daily living (ADLs)
• A severe loss or damage caused by a road traffic incident (RTI)

The amount of compensation that can be collected in a brain injury claim will also depend on a variety of factors, according to Grillo Law, such as the severity of the injury, medical evidence, loss of income, probable future medical care, coverage by insurance and the impact of the injury on the person’s lifestyle.

See Grillo Law’s guide to traumatic brain injury effects, causes, and legal implications for more information on how these injuries can be applicable to a legal case.

Key Factors That Affect the Value of a Brain Injury Claim

No single factor determines the value of a brain injury settlement. Lawyers, insurers, medical professionals, and experts may examine several types of evidence to understand how the injury has affected the individual and what losses are likely to continue in the future.

Some of the most important factors include the following.

Severity of the Injury

The severity of the traumatic brain injury can make a big difference to compensation.

Brain injuries can range from a concussion/mild traumatic brain injury to serious injuries resulting in permanent cognitive, neurological, physical, emotional and behavioural impairments. In practice, injury severity often shapes both the prognosis and the value of a claim. Even mild traumatic brain injuries or a mild TBI can lead to lasting problems, while severe brain injuries may involve a brain contusion or diffuse axonal injury, and diffuse axonal injury is a serious type of traumatic brain injury.

A person’s ability to: may be impaired for more serious injuries:

• Remember or process information
• Concentrate for extended periods
• Communicate effectively
• Control emotions or behaviour
• Work or attend school
• Drive
• Perform household responsibilities
• Participate in hobbies and social activities
• Care for children or other family members
• Live independently

The length of recovery is also important. Temporary symptoms could lead to a different claim value than the permanent symptom that could require life-long treatment or support.

A severe traumatic brain injury may also meet the legal definition of catastrophic impairment as set out in Ontario Law in some motor vehicle accident cases. Catastrophic impairment is a specific insurance classification, and does not necessarily mean that all brain injuries are of the medical category. Being found catastrophically impaired can also unlock higher medical and rehabilitation benefits under the Statutory Accident Benefits Schedule. There are statutory tests set out in the Statutory Accident Benefits Schedule that are used to determine catastrophic impairment in Ontario.

Medical Expenses

Medical costs and medical rehabilitation may be significant components of brain injury claims, especially if symptoms persist for months or years.

Treatment could include:

• Neurologists
• Neuropsychologists
• Occupational therapists
• Physiotherapists
• Physical therapy
• Psychologists or psychiatrists
• Speech-language pathologists
• Rehabilitation specialists
• Prescription medication
• Cognitive rehabilitation
• Assistive equipment
• Attendant care
• Home modifications

In more severe cases of brain injury, the future treatment needs are of particular significance.

Medical costs incurred by a settlement should not be the only factor taken into account. If the injury has caused ongoing impairments, including damage to brain tissue, future medical expenses may remain important long after the initial event, and significant medical bills tied to treatment, rehabilitation, support services, or attendant care can still shape the claim.

Ontario’s statutory accident benefits system may provide medical, rehabilitation and attendant care benefits for motor vehicle accidents, without regard to fault. These benefits continue to be required on an Ontario auto insurance policy as of July 1, 2026, and some other accident benefits are optional, depending on the policy.

Under the current policy, the standard limits of medical, rehabilitation, attendant care coverage in Ontario are $65,000 for non-catastrophic impairments and $1 million for catastrophic impairments.

For more details on the treatment, attendant care and other accident related expenses, read the Grillo Law article titled Compensation for Care After a Personal Injury Accident.

Financial Losses

Even a head injury or mild traumatic brain injury can also cause significant financial damages.

Others may not be able to work for a while, while they get better. Others may be able to return to work in a different capacity with fewer hours or accommodations in the workplace. If a person has a serious brain injury, that person might not be able to return to the job they had before the injury.

The financial damages that are taken into account within a personal injury lawsuit could encompass:

• Past lost income
• Reduced working hours
• Lost employment opportunities
• Loss of earning capacity
• Future income loss
• The loss of pension or employment benefits.
• The expenses of training or retraining for another career, or costs of changing careers.
• Out-of-pocket costs related to the injury as part of a personal injury claim.

Some injury victims seek compensation through a traumatic brain injury lawsuit or brain injury lawsuit when negligence caused the loss.

When determining future financial losses, the age of the person injured, occupation, education, and employment history, pre-accident income, and future career path could all be relevant factors.

A young professional who suffers a brain injury that renders him unable to hold on to a demanding position may have a significant financial impact even if he is eventually able to work in another capacity.

Income replacement benefits are also included in a car accident claim, and may depend on the insurance coverage that the person has in their auto insurance policy. Under Ontario policies, one of the accident benefits that can be optional is income replacement, starting July 1, 2026.

Pain and Suffering

Compensation can also cover the non-financial effects of a TBI. These damages are also known as pain and suffering or non-pecuniary damages. In Canada, non-pecuniary damages are subject to a cap established by the Supreme Court.

The damages for pain and suffering are not based on a receipt or bill of pay, as they are in the case of a medical bill or a paycheque. Rather, the evidence can show how the injury has affected the person’s life in terms of their physical health, emotional well-being, independence, relationships, hobbies and enjoyment.

These factors could include:

• Chronic headaches or physical pain
• Memory and concentration problems
• Fatigue and sleep disturbances
• Anxiety or depression
• Personality or behavioural changes
• Loss of independence
• Inability to participate in previous activities
• Reduced social interaction
• Strain on personal and family relationships
• Overall loss of enjoyment of life, including emotional distress, post concussive syndrome, and cognitive difficulties

If you are injured in an Ontario motor vehicle accident, there are special rules that apply to your claim for pain and suffering. A person who is injured generally cannot recover non-pecuniary damages from the protected automobile defendant under the Insurance Act unless is suffers permanent serious disfigurement or permanent serious impairment of an important physical, mental or psychological function. The cap is often described as around $340,000 in historic terms and is adjusted for inflation; as of 2025, the cap for pain and suffering damages is $460,969.

The circumstances should be evaluated individually as these requirements may have a significant impact on a motor vehicle brain injury claim.

How Brain Injury Compensation Is Calculated

Generally, in brain injury cases, compensation is determined by the losses suffered as a result of the accident, and how much they are worth in the past, present, and in the future. There is no single mathematical formula that can be used to calculate the amount of the settlement.

When determining the value of the claim, a lawyer might consider several types of damages:

1. Past medical and rehabilitation expenses: Treatment and other expenses already incurred because of the injury.
2. Future care costs: Expected future medical expenses for rehabilitation, therapy, medication, equipment, attendant care, or other medical support.
3. Past income loss: Income the injured person has already lost because they could not work or could work only reduced hours.
4. Future income loss or loss of earning capacity: The long-term financial effect of being unable to return to the same employment, hours, responsibilities, or career path.
5. Pain and suffering: Compensation for the physical, cognitive, psychological, and emotional effects of the injury and loss of enjoyment of life, since a brain injury affects cognition, emotions, and day-to-day function in different ways.
6. Housekeeping and care needs: In appropriate cases, the value of assistance required with household responsibilities or personal care.
7. Other accident-related expenses: Reasonable expenses caused by the injury may also form part of the damages analysis depending on the circumstances.

A fair settlement depends heavily on the quality of the medical evidence and expert support.

Medical evidence is particularly important in traumatic brain injury cases. Records from family physicians, neurologists, neuropsychologists, rehabilitation professionals, and other specialists can help establish the diagnosis, symptoms, prognosis, functional restrictions, and future care requirements.

Experts such as occupational therapists, life-care planners, vocational specialists, accountants, and economists may also be used in more serious cases to assess future care or financial losses.

How Grillo Law Can Help With Your Brain Injury Claim

Establishing an accident is not enough for a brain injury claim. It is important that the evidence shows how the person’s health, employment, independence, finances and future has been impacted by the injury.

Grillo Law has over 40 years of experience representing brain injury cases and personal injury cases in Ontario, including traumatic brain injuries and catastrophic injuries.

Depending on the circumstances of the case, a personal injury lawyer can help by:

• Investigating how the accident occurred
• Obtaining medical records and expert evidence
• Documenting the degree of brain damage
• Knowing what type of insurance benefits are available
• Determining the amount of income lost or expected to be lost.Evaluating lost or lost expected income
• Assessing future medical and rehab needs
• Gathering evidence related to the impact of the injury on everyday functioning
• Working with insurance companies to communicate and negotiate for fair compensation
• Evaluating long-term losses in proposed settlements
• Ensuring compliance with relevant deadlines in the law, including Ontario’s general two-year limitation period for civil claims
• Preparing the case when it is needed for litigation purposes.

Where the brain injury was caused by an accident with a motor vehicle, there may need to be coordination of accident benefits and a claim against a wrongdoer. More serious injuries might be subjected to further medical evaluations to assess if the person would qualify for catastrophic impairment.

Each brain injury claim in Ontario is unique with its own medical, financial and legal findings. Before taking a settlement from an insurance company, it’s important to realize that there may be losses that have already happened, and further losses that will likely continue and well into the future.

A personal injury lawyer can help pursue a fair settlement when severe injuries, serious TBI cases, or disputed liability are involved.
