- Date
- September 14, 2026
- Area of law
- Motor Vehicle Accident
- Key issue
- Whether the applicant's psychological injuries, assessed under Criterion 8 of the Statutory Accident Benefits Schedule, met the threshold for a catastrophic impairment designation.
- Outcome
- The Licence Appeal Tribunal found that the applicant did not establish a catastrophic impairment under Criterion 8, as she demonstrated only one marked impairment rather than the required three across four functional domains.
- Why it matters
- For anyone injured in an Ontario car accident, a catastrophic impairment designation unlocks significantly higher benefit limits — so understanding how the LAT evaluates psychological claims matters enormously.
Legal principle
The rule from this case
Under Ontario's Statutory Accident Benefits Schedule, a person can qualify as catastrophically impaired on psychological grounds (Criterion 8) by demonstrating either three 'marked' (Class 4) impairments or one 'extreme' (Class 5) impairment across four areas of functioning: activities of daily living, social functioning, concentration/persistence/pace, and adaptation. These ratings are assessed using the American Medical Association Guides to the Evaluation of Permanent Impairment, 4th edition. Crucially, the impairments must stem from a mental or behavioural disorder caused by the accident — not from physical pain or pre-existing conditions. Where evidence shows that a person's functional difficulties are driven primarily by chronic pain rather than a psychological disorder, those difficulties may not count toward the Criterion 8 threshold, even if the person genuinely struggles with daily tasks.
Important limits
What this does not mean
This decision does not mean that psychological injuries can never qualify as catastrophic impairments in Ontario. The LAT evaluates each case on its specific facts, including the credibility of expert reports and how well those reports account for the claimant's actual post-accident functioning. A different evidentiary record — with consistent expert opinions and documented functional decline — could support a different result. This decision also does not suggest that returning to work after an accident automatically disqualifies someone from a catastrophic designation. However, it does illustrate that when a claimant's own testimony and employment records contradict the assumptions underlying an expert's opinion, adjudicators may prefer the opinion of the expert whose analysis more accurately reflects the documented evidence.
What Does ‘Catastrophic Impairment’ Mean for Psychological Injuries in Ontario?
A catastrophic impairment designation is the highest classification available under Ontario’s accident benefits system, and it unlocks substantially higher benefit limits. For psychological injuries specifically, qualifying under Criterion 8 requires proof of at least three ‘marked’ impairments — or one ‘extreme’ impairment — across four defined areas of mental functioning. This is a high bar, and the LAT’s decision in Ricard v Certas Home and Auto Insurance Company, 2026 ONLAT 25-011325/AABS (CanLII) illustrates exactly why.

What Are the Four Areas of Functioning Under Criterion 8?
Criterion 8 assesses mental and behavioural impairment across four domains. The four areas are: activities of daily living, social functioning, concentration/persistence/pace (CPP), and adaptation (also described as deterioration in a work-like setting). Each domain is rated on a five-class scale ranging from no impairment (Class 1) through extreme impairment (Class 5). A ‘marked’ impairment at Class 4 means the person’s functioning is significantly impeded. An ‘extreme’ impairment at Class 5 means functioning is effectively precluded altogether.
To reach the catastrophic threshold, a claimant must show marked impairment in at least three of these four domains — or extreme impairment in at least one.
How Did the Tribunal Evaluate the Expert Psychiatric Evidence?
The Tribunal weighed competing psychiatric reports and preferred the insurer’s expert because his analysis more closely matched the documented evidence. The claimant’s psychiatrist rated her as having marked impairments across all four domains. However, the adjudicator found that this opinion rested on inaccurate factual assumptions — including that the claimant had not returned to work after the accident and had no significant pre-existing psychological history.
Employment records and family physician notes told a different story. The claimant had returned to work within weeks of the accident, held multiple positions over several years, and had a documented history of anxiety and depression predating the collision. Because the claimant’s expert did not account for these facts, the adjudicator gave his conclusions less weight.
Does Returning to Work After an Accident Hurt a Catastrophic Impairment Claim?
Returning to work does not automatically disqualify someone from a catastrophic designation, but it is highly relevant evidence. In this case, the claimant worked full-time in supervisory nursing roles for more than two years after the accident. The adjudicator found this level of functioning was inconsistent with marked impairment in social functioning and concentration/persistence/pace.
The Tribunal also noted that the claimant’s difficulties with task completion appeared to stem from physical pain — not from a mental or behavioural disorder. Under Criterion 8, only impairments caused by a mental or behavioural disorder count toward the threshold. Physical limitations, even severe ones, do not satisfy the test on their own.
What Role Do Pre-Existing Conditions Play in a Catastrophic Claim?
Pre-existing conditions complicate catastrophic impairment claims but do not automatically defeat them. The claimant here had pre-existing depression, anxiety, and significant spinal conditions before the accident. The key question is always whether the accident caused or materially worsened a mental or behavioural disorder that produces the claimed level of functional impairment.
Where an expert’s report fails to meaningfully engage with the claimant’s pre-accident health history, the adjudicator may find that the opinion overstates the accident’s contribution to the person’s current condition. Thorough, accurate expert opinions that address pre-existing conditions head-on tend to carry more weight.
What Happened With the Adaptation Domain?
Both psychiatric experts agreed that the claimant had a marked impairment in adaptation — the domain relating to functioning in work-like settings. The adjudicator accepted this finding. However, because the claimant could not establish marked impairment in at least two additional domains, she fell short of the three-domain threshold required for a catastrophic designation under Criterion 8.
This outcome illustrates that even partial success on individual domains does not guarantee a catastrophic finding. The threshold requires meeting the standard across multiple areas simultaneously.
Questions and Records to Discuss With a Lawyer
If you are pursuing or considering a catastrophic impairment claim based on psychological injuries, the following are the kinds of questions and records that may be relevant to discuss with legal counsel:
- What do your employment records, tax filings, and employer confirmations show about your work history before and after the accident?
- Do your treating physicians’ clinical notes accurately reflect your functional limitations, including any pre-existing conditions?
- Have your psychiatric or psychological assessors reviewed your complete medical history, including pre-accident mental health records?
- Are your reported limitations consistent across your testimony, your assessors’ reports, and independent records such as family doctor notes?
- Has anyone assessed whether your functional difficulties stem from a mental or behavioural disorder specifically, as distinct from physical pain or pre-existing conditions?

FAQ
Frequently asked questions
Timelines vary significantly depending on when the insurer's assessment is completed, whether the claim is disputed, and how long the LAT scheduling process takes. Disputes at the Licence Appeal Tribunal can take a year or more from application to hearing.
A catastrophic designation significantly increases the limits available for medical, rehabilitation, and attendant care benefits under the Statutory Accident Benefits Schedule. The specific amounts depend on the policy and the applicable version of the Schedule.
A LAT decision can be appealed to the Divisional Court of Ontario on questions of law. Appeals on questions of fact alone are generally not available, and the grounds for appeal are narrow.
