In three sentences: Ontario's auto insurance statutes expressly refer to "mental or psychological" function, so a psychological injury can be part of both an accident benefits claim and a lawsuit. In the tort claim, a psychological impairment has to meet the same threshold as a physical one, and the regulation requires physician evidence plus corroboration of the change in function. In accident benefits, the $3,500 Minor Injury Guideline limit applies to impairments that are predominantly a "minor injury", a term defined in the regulation, and whether a psychological condition changes that question is often contested.
Where the law mentions psychological injury
People searching for PTSD after a car accident in Ontario often ask first whether the law covers mental injury at all. The Insurance Act does not leave it out. Section 267.5 sets a gateway for non-pecuniary damages (pain and suffering) arising from bodily injury in a collision, and it applies to the owner, the occupants and anyone present at the incident. The gateway is death, permanent serious disfigurement, or permanent serious impairment of an important function that the statute describes as "physical, mental or psychological". The accident benefits regulation (Reg. 34/10, s. 3(1)) defines "impairment" as a loss or abnormality of a psychological, physiological or anatomical structure or function.
How courts decide what proof a mental injury requires, and how serious it must be, is a matter of case law that a lawyer can explain. This article does not discuss decided cases.
What psychological injury can look like
After a collision or a serious fall, people commonly describe:
- Post-traumatic stress: intrusive memories, nightmares, a sense of constant alertness, avoiding driving or the location
- Depression: loss of interest, hopelessness, withdrawal, disrupted sleep
- Anxiety and panic, particularly while driving or as a passenger
- Chronic pain with a mood component
- Adjustment difficulties where an active life is suddenly restricted
- Physical symptoms without clear imaging findings
The regulation's tests look at function: effects on work, training or most usual daily activities. For that reason the day-to-day changes in what a person can still do tend to matter.
Psychological conditions and the Minor Injury Guideline
The $3,500 limit applies to "predominantly a minor injury"
Section 18(1) of Reg. 34/10 sets a ceiling of $3,500 (plus any applicable HST) on the medical and rehabilitation benefits for an accident on or after June 3, 2019 where the impairment is predominantly a minor injury; amounts already paid under the Guideline count toward it. The regulation lists the minor injuries: sprains, strains, whiplash associated disorder, contusions, abrasions, lacerations and subluxations, together with clinically associated sequelae.
Psychological conditions do not appear in that list. Whether a person's impairment is predominantly a minor injury, or includes a psychological impairment that is separate from it, depends on the medical evidence and may be disputed by the insurer. Section 18(2) also provides a separate exception for a person whose health practitioner gives compelling evidence of a pre-existing medical condition, recorded before the accident, that would keep the person from reaching maximal recovery if the limit applied.
Symptoms that are not reported are not recorded, and unrecorded symptoms are difficult to rely on later. A family doctor can document symptoms and arrange treatment or assessment. The benefits process is covered in our accident benefits article.
The threshold names psychological function
In a lawsuit against the at-fault party, the same gateway applies. Section 4.2 of Reg. 461/96 turns it into criteria: a substantial effect on the ability to keep working or training, or on most daily activities for the person's age, and an impairment that has been continuous since the incident and is not expected to improve substantially on the medical evidence.
Section 4.3 adds evidence requirements. One or more physicians with training and experience in the kind of impairment alleged must address its nature, permanence, the function affected and that function's importance, and conclude that the automobile caused it. Separate evidence must also back up the claimed change in function. Which professionals' reports are used, and how, is a question for a lawyer. Material that is often gathered includes:
- Treatment records from psychiatrists, psychologists or other treating providers over time
- Family doctor records from before and after the collision
- Accounts from family, friends and employers describing the change
- Documented work absence, accommodation or job loss
Our compensation calculation guide shows where the threshold sits within an award.
Issues that are commonly raised
- Pre-existing conditions. Prior records of stress, anxiety or low mood may be produced, and how they relate to the accident is a medical and legal question.
- Motivation. The other side may suggest that symptoms are linked to the claim. Consistent records across time and providers are relevant.
- Absence of imaging findings. Mental health conditions do not appear on a scan, so the evidence is usually clinical.
- Surveillance and social media. Photographs can be presented out of context. Symptoms can vary from day to day.
- Treatment gaps. Missed appointments can be portrayed as recovery, so the reasons may be worth documenting.
Evidence a lawyer typically asks about
- Early and repeated reporting of symptoms to treating providers
- Referrals to psychiatry, psychology or a trauma programme, and whether they were followed
- A journal of sleep, mood and avoidance
- People who can describe the before and after
- Written records of work impact
- A candid account of prior mental health history
When to talk to a lawyer about a psychological injury
- The insurer has placed the claim in the Minor Injury Guideline and symptoms are continuing
- Treatment funding has been refused or limited
- A deadline is approaching or has passed
- A threshold motion or an insurer's medical examination is scheduled
- Work has been lost or reduced because of the condition
Frequently asked questions
Can I claim compensation for PTSD after a car accident in Ontario?
A psychological impairment can form part of both accident benefits and a tort claim. Whether the evidence is enough depends on the facts, and a lawyer can review it.
Do I need a psychiatric diagnosis?
The wording of the threshold does not mention a diagnosis, but the regulation calls for physician evidence on the impairment. What a court will accept in a given case is a question for a lawyer.
Can psychological injury alone meet the tort threshold?
The statute lists "physical, mental or psychological" function in the alternative. It also speaks of damages for "bodily injury", and how that wording applies to a purely psychological condition is a question for a lawyer.
Will a psychological diagnosis get me out of the $3,500 limit?
That depends on the medical evidence. The limit in s. 18(1) applies to impairments that are predominantly a minor injury, and insurers may dispute how it applies.
What if I had anxiety before the accident?
Prior history is relevant to causation and is typically reviewed in the records. A lawyer can explain how it is likely to be approached.
How long do I have to bring a claim?
The Limitations Act, 2002 (s. 4) generally allows two years from when the claim was discovered. Accident benefits run on shorter clocks in Reg. 34/10: notice to the insurer by the seventh day after the circumstances arose or soon after (s. 32(1)), and a completed application within 30 days of receiving the forms (s. 32(5)). Applying these to a particular case turns on the facts, so a lawyer should confirm the dates right away.
Questions a lawyer would typically look at
- How the diagnosis and treatment connect to the incident
- What records and assessments exist
- How it is valued compared with physical injury
Good to know: Appointment records and letters from treating professionals are what a lawyer would usually ask for.
