PART 4: WSIB’s Denial & My Response

WSIB’s Denial Reason

WSIB denied my claim stating:

[COPY EXACT TEXT FROM WSIB DENIAL LETTER]

SECTION A: Countering “Incident Wasn’t Traumatic Enough”

[ONLY USE THIS SECTION IF WSIB SAID YOUR INCIDENT WASN’T TRAUMATIC]

WSIB’s denial contradicts diagnostic criteria and legal precedent for workplace psychological injuries.

Medical/Diagnostic Standards

DSM-5 PTSD Criterion A does NOT require:

• ❌ Life-threatening danger
• ❌ Physical injury
• ❌ Multiple traumatic events
• ❌ Violence or assault

DSM-5 PTSD Criterion A definition:

“Exposure to actual or threatened death, serious injury, or sexual violence in one (or more) of the following ways: (1) Directly experiencing the traumatic event(s)”

My incident qualifies:

• ✅ I directly experienced [assault / threat of violence / witnessing a traumatic death/injury / sexual harassment/assault]
• ✅ I perceived [threat to my safety / serious injury / sexual violence]
• ✅ My psychologist/psychiatrist diagnosed PTSD based on DSM-5 criteria

WSIB cannot override diagnostic criteria to deny claims.

Legal Precedent

WSIAT Decision No. [CITE RELEVANT TRIBUNAL DECISION IF KNOWN]:

• Tribunals have allowed PTSD claims for: verbal threats, witnessing traumatic events, cumulative workplace stress
• “Traumatic” is defined by worker’s psychological response, not WSIB’s subjective assessment of severity

My Response to WSIB’s Characterization:

[IF WSIB SAID “MINOR INCIDENT”:]

WSIB characterized my experience as “minor,” but:

• I was [assaulted/threatened/exposed to traumatic material]
• I immediately experienced [terror/shock/dissociation]
• I developed PTSD as diagnosed by qualified mental health professional
• The impact on ME determines whether incident is traumatic, not WSIB’s opinion

[IF WSIB SAID “NO PHYSICAL INJURY”:]

WSIB’s requirement of physical injury contradicts DSM-5 and case law:

• PTSD does NOT require physical injury
• Psychological injury from traumatic event IS compensable under WSIA
• [CITE: Decision No. XXXX allowed PTSD claim without physical injury]

[IF WSIB SAID “YOU WEREN’T IN DANGER”:]

WSIB’s after-the-fact assessment ignores my perception at the time:

• I believed I was [in danger of serious harm/going to be killed/going to be sexually assaulted]
• Criterion A includes “PERCEIVED threat”
• My psychologist confirms: “Patient’s perception of threat was reasonable and triggered PTSD”

WSIB’s denial based on “insufficient trauma” contradicts DSM-5 diagnostic criteria and legal standards for workplace PTSD.

SECTION B: Countering “Pre-Existing Mental Health Condition”

[ONLY USE THIS SECTION IF WSIB BLAMED PRE-EXISTING DEPRESSION/ANXIETY]

WSIB’s denial based on pre-existing mental health condition contradicts Pasiechnyk v. WSIB (2015) and established tribunal precedent.

Pasiechnyk Legal Framework

Pasiechnyk v. WSIB (Ontario Court of Appeal, 2015):

• Legal Standard: Pre-existing condition + workplace incident = compensable IF workplace incident caused GREATER SEVERITY
• WSIB’s Burden: WSIB must prove workplace incident did NOT cause greater severity
• Worker’s Burden: Worker demonstrates functional deterioration after workplace incident

My Functional Status BEFORE Workplace Incident

[CHOOSE APPLICABLE DESCRIPTION:]

[IF YOU HAD PRIOR DEPRESSION/ANXIETY THAT WAS CONTROLLED:]

Yes, I was diagnosed with [depression/anxiety] in [YEAR]. HOWEVER, before the workplace incident on DATE:

• My condition was STABLE on medication ([medication name/dose])
• I was working FULL-TIME without accommodation
• I had not required crisis intervention, hospitalization, or medication changes in [X years]
• I was able to [work, socialize, perform daily activities] without limitation
• My last mental health appointment was [DATE, X months before incident] - routine follow-up only

[IF YOU HAD PRIOR MENTAL HEALTH ISSUES THAT WERE RESOLVED:]

Yes, I experienced [depression/anxiety/PTSD] in [YEAR] from [prior life event, e.g., divorce, parent’s death]. I received treatment [therapy/medication] and RECOVERED. Before the workplace incident on DATE:

• I had been symptom-free for [X years]
• No mental health treatment since [YEAR]
• Working full-time, functionally independent
• [MY PSYCHOLOGIST STATES: “Patient had fully recovered from prior episode before workplace incident”]

What Changed AFTER Workplace Incident

Immediate Change:

• Within days/weeks: Developed [new symptoms: e.g., flashbacks, nightmares, panic attacks] that I had NEVER experienced before
• Unable to work ([took leave on DATE])

Comparison:

Medical Opinion:

[PSYCHOLOGIST/PSYCHIATRIST NAME] states: “Patient’s pre-existing [depression/anxiety] was [stable/resolved] before workplace incident. The workplace [assault/trauma] caused NEW onset of PTSD with GREATER SEVERITY than any prior mental health condition. Current symptoms are DIRECTLY caused by the workplace incident.”

Applying Pasiechnyk

1. Greater Severity: ✅ My current mental health condition is FAR MORE SEVERE than any prior condition
2. Functional Deterioration: ✅ I went from working full-time to unable to work
3. Temporal Connection: ✅ Deterioration occurred IMMEDIATELY after workplace incident
4. Medical Causation: ✅ My psychologist/psychiatrist confirms workplace incident caused greater severity

WSIB has NOT proven (and cannot prove) that the workplace incident did NOT cause greater severity. Under Pasiechnyk, my claim is compensable.

SECTION C: Countering “This Is Really Chronic Pain, Not Psychological”

[USE THIS SECTION IF WSIB SAYS YOU HAVE CHRONIC PAIN, NOT MENTAL HEALTH INJURY]

WSIB’s reclassification of my diagnosed PTSD/depression as “chronic pain psychological reaction” contradicts medical evidence and is an improper cost-saving tactic.

My Diagnosis

[PSYCHOLOGIST/PSYCHIATRIST NAME] diagnosed:

• Primary Diagnosis: [Post-Traumatic Stress Disorder / Major Depressive Disorder / Generalized Anxiety Disorder]
• DSM-5 Code: [309.81 (PTSD) / 296.22 (Depression) / 300.02 (Anxiety)]
• Cause: Workplace traumatic incident on DATE: [describe]

My Symptoms:

• [LIST PTSD/DEPRESSION/ANXIETY SYMPTOMS, e.g.:]
  • Flashbacks of [traumatic incident]
  • Nightmares about [incident]
  • Severe anxiety and hypervigilance
  • Avoidance of [workplace/similar situations]
  • Depression, suicidal thoughts [if applicable]

[IF YOU ALSO HAVE PHYSICAL PAIN:]

Yes, I also have [back pain/headaches/other physical pain] from [work injury]. HOWEVER:

• My physical pain and psychological injury are SEPARATE conditions
• Physical pain has NOT prevented me from working - PTSD/anxiety has
• I could manage physical pain with medication - I CANNOT manage PTSD/flashbacks/panic attacks
• My psychologist confirms: “Patient’s PTSD is PRIMARY disabling condition, not pain”

WSIB’s “Conflation Bias”

WSIB systematically reclassifies psychological injuries as “pain-related psychological reactions”:

• WSIB’s Tactic: Psychological injury = short-term claim → “pain reaction” = frequently denied or terminated early
• Impact: Our audit found 107 cases (2020-2026) where WSIB claimed mental health was “really chronicpain”

My case:

• I have a DIAGNOSED psychological injury (PTSD/depression/anxiety)
• My disability is from PSYCHOLOGICAL SYMPTOMS (flashbacks, avoidance, anxiety), NOT pain
• [IF APPLICABLE: My physical injury has healed/is managed, but psychological injury persists]

WSIB cannot override my psychologist’s/psychiatrist’s diagnosis to avoid compensating brain injury.

SECTION D: Countering “Normal Employment Stress”

[USE THIS SECTION IF WSIB SAYS YOUR CLAIM IS “NORMAL WORKPLACE STRESS”]

WSIB’s denial based on “routine employment duties” contradicts WSIA Section 13 and tribunal precedent.

Legal Standard: WSIA Section 13(4)

WSIA Section 13(4):

“Chronic mental stress” from normal employment duties is NOT compensable EXCEPT:

• ACUTE mental stress from specific traumatic incident IS compensable
• Chronic stress from cumulative traumatic events IS compensable if objectively traumatic

My Claim: [CHOOSE ONE:]

[OPTION A: ACUTE TRAUMATIC INCIDENT]

My claim is for ACUTE mental stress (PTSD) from a SPECIFIC TRAUMATIC INCIDENT on DATE, not “chronic stress from employment duties.”

The incident ([assault/threat/witnessing death or serious injury/sexual violence]) was:

• ✅ Specific (occurred DATE at [TIME])
• ✅ Traumatic (meets DSM-5 Criterion A for PTSD)
• ✅ Beyond normal employment duties (even for healthcare/police/emergency workers, [specific incident] was extraordinary)

[CITE TRIBUNAL PRECEDENT IF KNOWN:] Decision No. XXX: “[Workplace assaults/witnessing traumatic deaths/threats of violence] are acute traumatic incidents, not ‘normal employment stress’“

[OPTION B: CUMULATIVE TRAUMATIC EVENTS]

My claim is for chronic PTSD from CUMULATIVE TRAUMATIC EVENTS over [X years], not “stress from normal duties.”

I experienced [NUMBER] traumatic incidents in [TIMEFRAME]:

• [etc.]

Each incident was OBJECTIVELY TRAUMATIC (assaults, threats, witnessing deaths/serious injuries). The cumulative effect caused PTSD.

This is NOT “normal employment stress.” These are traumatic events that would cause psychological injury in ANY occupation.

Employer Did Not Provide Safe Workplace

[IF APPLICABLE:]

My employer [NAME] failed to:

• Provide adequate security/safety measures
• Train staff on de-escalation/violence prevention
• Remove known dangerous [patients/customers]
• Respond to my reports of [threats/harassment/unsafe conditions]

Employer’s failure to provide safe workplace does NOT make traumatic incidents “normal employment duties.”

WSIB’s “normal stress” argument fails. My claim is for acute traumatic stress / cumulative traumatic events, both compensable under WSIA.

PART 5: Medical Evidence

Attached Medical Reports

[CHECK ALL THAT APPLY AND ATTACH COPIES:]

• ☐ Psychologist assessment report dated DATE
• ☐ Psychiatrist assessment report dated DATE
• ☐ Family physician clinical notes
• ☐ Emergency department records from DATE
• ☐ Hospital admission records [if applicable]
• ☐ Medication records
• ☐ Therapy/counseling session notes

Summary of Medical Opinion

[PSYCHOLOGIST/PSYCHIATRIST NAME] concludes:

[COPY KEY EXCERPTS FROM MEDICAL REPORT, e.g.:]

“Patient meets DSM-5 diagnostic criteria for Post-Traumatic Stress Disorder causally related to workplace assault on DATE. Symptoms include intrusive re-experiencing, avoidance, negative alterations in mood/cognition, and alterations in arousal/reactivity. Patient is unable to work in any capacity and requires ongoing intensive psychotherapy and psychiatric medication management. Prognosis is guarded; patient will likely require long-term treatment and may never return to [previous occupation].”

PART 6: Request for Relief

I respectfully request that WSIAT:

1. ALLOW my appeal and find that my [PTSD/depression/anxiety] is a compensable workplace injury arising from [traumatic incident on DATE]

2. ORDER WSIB to provide:
   • Full wage loss benefits retroactive to [DATE I stopped working]
   • Coverage of all medical treatment costs:
     • Psychotherapy (weekly sessions with [THERAPIST NAME])
     • Psychiatric medication management (monthly appointments with [PSYCHIATRIST NAME])
     • Medications: [list all mental health medications]
     • [If applicable: “Inpatient psychiatric treatment if required”]
   • Vocational rehabilitation assessment and retraining (I cannot return to [previous occupation] due to PTSD triggers)
   • Non-Economic Loss (NEL) benefits if permanent impairment
3. ORDER WSIB to cover any future recurrences of PTSD/depression/anxiety related to this workplace injury

PART 7: Conclusion

I suffered a traumatic workplace injury on DATE that caused [PTSD/depression/anxiety]. I meet all diagnostic criteria (DSM-5), have received ongoing treatment from qualified mental health professionals, and remain unable to work [X months] after the incident.

WSIB’s denial [contradicts diagnostic criteria / ignores Pasiechnyk legal standard / improperly reclassifies my injury / misapplies “normal stress” exclusion]. The medical and legal evidence clearly establishes my injury is compensable.

I request WSIAT allow my appeal and order WSIB to provide the benefits and treatment I am entitled to under the Workplace Safety and Insurance Act.
