RE: Appeal of Decision - WSIB Claim #[YOUR CLAIM NUMBER]
Worker Name: [YOUR NAME]
Employer: [EMPLOYER NAME]
Date of Injury: [INJURY DATE]

STATEMENT OF APPEAL

I am writing to appeal the WSIB decision dated [DECISION DATE] which denied my claim for [benefits denied]. This decision is incorrect because the medical evidence clearly shows my low back injury is work-related and has resulted in [permanent impairment / ongoing disability / need for further treatment].

BACKGROUND

Employment Details

  • Employer: [COMPANY NAME]
  • Job Title: [YOUR JOB TITLE]
  • Duties: [DESCRIBE PHYSICAL DEMANDS - e.g., “repetitive heavy lifting of 50+ lb boxes, frequent bending and twisting, standing 8-10 hours per shift”]
  • Years in position: [DURATION]

Injury Incident

On [SPECIFIC DATE], I sustained a low back injury while [DESCRIBE SPECIFIC EVENT - e.g., “lifting a 75-pound pallet from ground level to shoulder height”].

What happened: [DETAILED DESCRIPTION - e.g., “I felt immediate sharp pain in my lower back radiating down my left leg. I reported the incident to my supervisor [SUPERVISOR NAME] immediately and sought medical attention at [HOSPITAL/CLINIC NAME] that same day.”]

Witnesses: [NAME ANY CO-WORKERS WHO SAW THE INCIDENT]

Medical History Before Injury

Prior to this workplace incident, I was in good health with no history of back problems. I was able to perform all job duties without restriction and had no absenteeism related to back pain.

[OR, if you had pre-existing condition:]

Prior to this workplace incident, I had [DESCRIBE MILD PRE-EXISTING CONDITION - e.g., “occasional mild low back stiffness managed with over-the-counter pain relievers”]. However, I was fully capable of performing all job duties and had never missed work due to back pain. The workplace injury on [DATE] significantly aggravated this pre-existing condition, rendering me unable to continue my employment.

MEDICAL EVIDENCE

Diagnosis

I have been diagnosed with:

  • [DIAGNOSIS 1 - e.g., “Lumbar disc herniation at L4-L5 with radiculopathy”]
  • [DIAGNOSIS 2 - e.g., “Chronic low back pain”]
  • [DIAGNOSIS 3 - e.g., “Sciatica affecting left lower extremity”]

Treating Physicians

Primary Care: Dr. [NAME], [CLINIC], [PHONE]
Specialist: Dr. [NAME], [SPECIALTY - e.g., Orthopedic Surgeon], [PHONE]

Objective Medical Findings

[LIST DIAGNOSTIC TEST RESULTS:]

MRI dated [DATE]:

  • [FINDINGS - e.g., “L4-L5 disc herniation with nerve root compression”]

X-Ray dated [DATE]:

  • [FINDINGS - e.g., “Loss of normal lumbar lordosis, disc space narrowing”]

CT Scan dated [DATE]:

  • [FINDINGS]

Treatment History

Since the injury, I have undergone the following treatment:

✓ Medications: [LIST - e.g., “Naproxen 500mg twice daily, Gabapentin 300mg three times daily for neuropathic pain”]
✓ Physiotherapy: [DETAILS - e.g., “12 sessions at [CLINIC NAME], minimal improvement”]
✓ Injections: [IF APPLICABLE - e.g., “Epidural steroid injection on [DATE] provided temporary relief for 6 weeks”]
✓ Surgery: [IF APPLICABLE]
✓ Other: [e.g., “TENS unit, heat therapy, modified duties attempt”]

Despite these treatment efforts, I continue to experience significant pain and functional limitations.

WHY THE WSIB DECISION IS WRONG

Issue 1: Work-Relatedness

The WSIB decision states: [QUOTE FROM DENIAL LETTER]

This is incorrect because:

  1. Temporal Connection: My back pain began immediately following the workplace incident on [DATE]. Prior to this, I had no similar symptoms.

  2. Medical Opinion: My treating physician Dr. [NAME] has clearly stated in their report dated [DATE]:

    “[QUOTE DOCTOR’S CAUSATION STATEMENT - e.g., ‘In my medical opinion, the patient’s lumbar disc herniation is directly caused by the heavy lifting incident at work on [DATE]’]”

  3. Consistent Reporting: I reported this injury to my employer the same day it occurred and sought immediate medical attention, demonstrating the work-related nature of the injury.

  4. Job Demands: My job required [HEAVY PHYSICAL DEMANDS] which medical literature recognizes as risk factors for low back injury.

[IF APPLICABLE - PRE-EXISTING CONDITION ARGUMENT:]

Issue 2: Pre-Existing Condition Claim

The WSIB states my condition is pre-existing and not work-related.

This is incorrect because:

The law is clear: a pre-existing condition does not disqualify a claim if the work aggravated or accelerated the condition. In my case:

Before workplace injury: [MILD SYMPTOMS, FULLY FUNCTIONAL]
After workplace injury: [SEVERE SYMPTOMS, UNABLE TO WORK]

This dramatic worsening is documented by:

  • Dr. [NAME]’s report showing functional decline
  • Imaging showing structural damage not present before (if applicable)
  • Treatment escalation (now requiring [STRONGER MEDS/SURGERY/ETC.])

Medical literature confirms that workplace heavy lifting can aggravate degenerative disc conditions, which is exactly what occurred in my case.

Issue 3: Functional Limitations

The WSIB states I can return to work.

This is incorrect because:

My functional limitations, as documented by Dr. [NAME] on [DATE], include:

❌ Cannot lift: More than [X] pounds
❌ Cannot stand/walk: Longer than [X] minutes without severe pain
❌ Cannot bend/twist: Required for [JOB DUTIES]
❌ Cannot sit: Prolonged sitting causes severe pain and numbness

These restrictions make it impossible to perform my pre-injury job, which requires:

  • Lifting 50+ pounds regularly
  • Standing/walking 8+ hours per shift
  • Frequent bending and twisting

Modified work attempts failed: My employer attempted to accommodate me with [DESCRIBE MODIFIED DUTIES] from [DATE] to [DATE]. I was unable to continue due to [SEVERE PAIN/SYMPTOM WORSENING].

ENTITLEMENT REQUESTED

I am requesting the following benefits:

✓ Loss of Earnings (LOE) Benefits: From [DATE] to present, as I am unable to work due to this compensable injury
✓ Treatment Benefits: Continued coverage for physiotherapy, medications, and any recommended interventions including [SURGERY/INJECTIONS/OTHER]
✓ Permanent Impairment Award: Once I reach maximum medical recovery, I request assessment for permanent impairment
✓ Vocational Rehabilitation: If unable to return to my pre-injury job, assistance with retraining

SUPPORTING DOCUMENTATION

Please find enclosed:

  1. Medical reports from Dr. [NAME] dated [DATES]
  2. MRI report dated [DATE]
  3. Physiotherapy records from [CLINIC]
  4. Employer incident report dated [DATE]
  5. Witness statement from [CO-WORKER NAME] (if applicable)
  6. Pain diary documenting daily symptoms from [DATE] to [DATE]

CONCLUSION

The medical evidence clearly establishes that:

  1. I sustained a work-related low back injury on [DATE]
  2. This injury has resulted in permanent/ongoing impairment and disability
  3. I am unable to perform my pre-injury job due to functional limitations
  4. I am entitled to WSIB benefits as per the Workplace Safety and Insurance Act

I respectfully request that WSIB reverse its decision and grant my claim for the benefits outlined above.

I am available for any further medical assessments or to provide additional information. Please contact me at [PHONE] or [EMAIL].

Thank you for your consideration.
