When an injury is severe enough to qualify as catastrophic under Ontario law, the entire claim changes. Medical and rehabilitation benefits can increase dramatically. Attendant care support may become available at a much higher level. The value of the lawsuit against the at-fault party can also increase substantially.

But insurance companies fight catastrophic injury designations aggressively because granting that designation costs them more. At Cambria Law Firm, we help seriously injured clients build the medical, legal, and financial evidence needed to pursue the catastrophic designation and the compensation that follows.

Critical: The CAT Designation Changes Everything

A catastrophic impairment designation can unlock access to significantly higher medical, rehabilitation, and attendant care benefits under Ontario’s accident benefits system.

This designation is not automatic. Insurers often challenge it through their own medical examinations, reports, and technical arguments.

If your injury is serious, the goal is not just to open a claim. The goal is to prove the full long-term impact of the injury before the insurer minimizes it.

What Is a Catastrophic Injury?

Ontario’s Statutory Accident Benefits Schedule defines catastrophic impairment using specific medical and functional criteria. These claims usually involve severe, permanent, or life-altering injuries.

Paraplegia or Quadriplegia Loss of use of both legs, or all four limbs, may qualify as catastrophic depending on the medical evidence and statutory criteria.
Amputation Loss of an arm, leg, hand, or foot may qualify as catastrophic, especially where the injury creates permanent mobility, employment, or care limitations.
Loss of Vision Total loss of vision in both eyes may qualify as catastrophic under Ontario’s accident benefits framework.
Traumatic Brain Injury A severe brain injury may qualify where cognitive, behavioural, psychological, or neurological impairment significantly affects daily life and functioning.
Whole Person Impairment A person may qualify where medical assessors determine a 55% or greater whole person impairment using recognized assessment standards.
Children with Serious Brain or Spinal Injuries A serious brain or spinal cord injury that permanently affects a child’s development may support a catastrophic impairment claim.

Why Insurers Fight the CAT Designation

A non-catastrophic injury has much lower medical and rehabilitation benefit limits. A catastrophic designation can unlock far higher benefits, including major medical, rehabilitation, and attendant care support.

That is why insurers often commission their own medical assessors to argue that the injury does not meet the catastrophic threshold. These assessments may contradict the findings of treating doctors, rehabilitation specialists, or independent experts.

How Cambria Law Responds

We retain independent, court-qualified medical experts to counter insurer examination reports, document the full injury impact, and build the evidence needed to support the catastrophic designation.

How the CAT Designation Changes Your Claim

The difference between non-catastrophic and catastrophic is not just financial. It determines the level of care, support, equipment, and long-term planning a seriously injured person may access.

Benefit Non-Catastrophic Catastrophic
Medical & Rehabilitation Lower benefit limits $1,000,000+ may be available
Attendant Care Limited support Significantly higher support may be available
Home or Vehicle Modification Limited funding May be funded where medically required
Income Replacement Available based on eligibility May continue long term where required
Case Manager Optional or limited Often funded in serious cases

Types of Catastrophic Injury Claims We Handle

Traumatic Brain Injury

Brain injuries can affect memory, concentration, mood, personality, speech, balance, and employability. We work with neuropsychologists, neurologists, and rehabilitation specialists to document the true long-term impact.

Spinal Cord Injury

Spinal cord injuries involving paralysis, partial paralysis, chronic pain, or physical dysfunction require lifetime care planning, occupational therapy assessments, medical evidence, and income loss analysis.

Amputation

Limb loss can require prosthetics, rehabilitation, future replacement costs, home modifications, workplace accommodations, and psychological support. The full claim must account for lifetime needs.

Serious Burn Injuries

Severe burns may involve surgeries, grafting, scarring, infection risk, psychological trauma, and long-term care. These cases may qualify through whole person impairment analysis.

Multiple Serious Fractures

Multiple fractures may qualify as catastrophic when the combined impairments reach the required threshold. These files require coordination across orthopedic, rehabilitation, and functional assessment evidence.

The SABS July 2026 Changes

For policies renewed on or after July 1, 2026, Ontario’s SABS benefit structure changes significantly for non-catastrophic claims. Catastrophic impairment benefit structures remain more stable, but the applicable coverage depends on the accident date, policy renewal date, and specific insurance terms.

If you suffered a serious injury, you should not guess which benefit regime applies. The wrong assumption can affect treatment access, claim strategy, and settlement timing.

Why Catastrophic Injury Claims Are Different

Catastrophic injury claims are not simply larger personal injury claims. They are more complex because they require medical, functional, economic, and legal evidence working together.

Lifetime Future Care Costs Future medical treatment, therapy, equipment, support workers, and home modifications must be calculated across the injured person’s lifetime.
Occupational Therapy Evidence Occupational therapists assess the equipment, home changes, mobility supports, and daily living assistance required for long-term functioning.
Neuropsychological Testing For brain injury cases, testing may reveal cognitive impairment that is not obvious to family, employers, insurers, or even treating providers.
Multiple Medical Disciplines Serious injury files often require orthopedic, neurological, psychological, psychiatric, rehabilitation, and economic evidence.
Settlement Timing Settling too early can be financially damaging if the full injury picture, future care cost, and long-term income loss are not yet understood.
