A chronic fatigue disability lawyer can help if your short-term or long-term disability claim has been denied, delayed or cut off by an insurance company.
Chronic fatigue syndrome, also called myalgic encephalomyelitis or ME/CFS, can cause profound exhaustion, post-exertional malaise, unrefreshing sleep, brain fog, pain and dizziness.
An insurer may accept that you experience fatigue but argue that medical testing is normal, your symptoms are subjective or a gradual exercise and return-to-work program should restore your capacity.
Samfiru Tumarkin LLP represents people with denied and terminated chronic fatigue disability claims throughout Canada, excluding Quebec.

How Can a Chronic Fatigue Disability Lawyer Help?
A disability lawyer can review your insurance policy, denial letter, medical evidence and occupational duties to determine why the insurer refused or terminated your benefits.
A lawyer may help by:
-
Explaining the definition of disability in your policy
-
Identifying weaknesses or inconsistencies in the insurer’s decision
-
Connecting fatigue and post-exertional symptoms to your occupational duties
-
Addressing arguments about normal medical testing
-
Documenting brain fog, sleep problems and unreliable attendance
-
Responding to pressure involving exercise, rehabilitation or return to work
-
Reviewing surveillance and insurer-arranged assessments
-
Determining what additional evidence may strengthen your claim
-
Negotiating directly with the insurance company
-
Starting legal action when appropriate
Connecting Chronic Fatigue to Your Job
A diagnosis alone does not explain why you can’t work. The evidence should connect your symptoms to the actual physical, cognitive and attendance requirements of your occupation.
For example:
-
Severe fatigue may prevent reliable attendance and sustained productivity
-
Post-exertional malaise may cause a delayed crash after physical or mental activity
-
Brain fog may interfere with memory, concentration and information processing
-
Orthostatic symptoms may make standing, walking or remaining upright difficult
-
Unrefreshing sleep may affect alertness, pace and workplace safety
When Should You Contact a Chronic Fatigue Disability Lawyer?
Speak with a disability lawyer promptly if:
-
Your STD or LTD application was denied
-
Your approved benefits were later cut off
-
The insurer says there is no objective medical evidence
-
Your fatigue or brain fog is described as subjective
-
Post-exertional symptom worsening is being ignored
-
You are being told to increase exercise or activity
-
The insurer says you can perform sedentary or remote work
-
A failed work attempt is being used as proof that you can work
-
You are being pressured into rehabilitation or an early return to work
-
Your benefits are under review at the change of definition
-
The insurer has invited you to submit an internal appeal
Should You Call Before Your Benefits End?
You do not always need to wait for a formal termination letter.
Warning signs may include:
-
Repeated requests for medical updates
-
An insurer-arranged medical or functional assessment
-
A rehabilitation consultant becoming involved
-
Pressure to increase activity or work hours
-
Questions about your daily activities or social media
-
A vocational report identifying alternative occupations
-
Notice of an upcoming two-year review
Should You File an Internal Appeal?
Do not assume an internal appeal is your best option.
The same insurer that denied your claim will review the appeal. Resubmitting similar information may produce the same result while delaying other legal options.
A disability lawyer can review the denial and explain your options before you decide how to proceed.
What Chronic Fatigue Disability Claims Can a Lawyer Handle?
ME/CFS Disability Claims
ME/CFS is a serious, long-lasting illness that can substantially reduce a person’s ability to complete their usual activities.
Common features include profound fatigue, post-exertional malaise, unrefreshing sleep, cognitive impairment and orthostatic intolerance.
Chronic Fatigue Caused by Another Condition
Chronic fatigue may also occur alongside:
-
Fibromyalgia
-
Autoimmune disease
-
Cancer or cancer treatment
-
Sleep disorders
-
Depression or anxiety
-
Neurological conditions
-
Other chronic illnesses
The insurer should consider your complete medical condition rather than demanding that fatigue be assessed as a separate diagnosis.
Long COVID Fatigue Claims
Long COVID may cause severe fatigue, brain fog and post-exertional symptom worsening that overlaps with ME/CFS.
Read our guide to Long COVID disability claims.
Chronic Fatigue With Fibromyalgia
Fibromyalgia and ME/CFS may involve overlapping problems with fatigue, sleep, pain and cognition.
The insurer should assess their combined effect rather than arguing that no single condition is disabling on its own.
For broader eligibility information, read our guide to chronic fatigue disability benefits in Canada.
Why Are Chronic Fatigue Disability Claims Denied?
The Insurer Says There Is No Objective Test
There is no single confirmatory test for ME/CFS. Diagnosis generally involves a detailed medical history, clinical assessment and investigation of other possible causes.
Normal bloodwork or imaging does not establish that you can maintain attendance, concentration and productivity throughout a workweek.
The Insurer Treats Fatigue as a Symptom, Not a Disability
The insurer may argue that fatigue is vague or common.
The relevant question is not whether many people experience tiredness. It is whether your severe, persistent symptoms prevent you from performing your occupational duties reliably.
Post-Exertional Malaise Is Ignored
Post-exertional malaise involves worsening symptoms after physical, cognitive or emotional activity.
The increase may be delayed and may last for days or longer. This means a short appointment, household task or work trial may not reveal the full effect of the activity.
Medical evidence should explain:
-
What level of activity triggers symptom worsening
-
Whether the response is delayed
-
Which symptoms increase
-
How long recovery takes
-
Why the activity can’t be repeated consistently
The Insurer Says Exercise Will Restore Your Capacity
Exercise may help people with many medical conditions, but standard vigorous exercise programs may worsen ME/CFS symptoms.
Rehabilitation and activity recommendations should account for your individual limits and the risk of post-exertional malaise.
The insurer should consider whether a proposed program is medically appropriate—not simply whether more activity could theoretically improve conditioning.
The Insurer Says You Can Perform Sedentary Work
The ability to sit does not establish that you can perform sedentary work.
Desk jobs still require concentration, memory, communication, attendance and sustained mental effort.
Cognitive activity itself may worsen symptoms or require prolonged recovery.
The Insurer Says You Can Work From Home
Remote work may remove the commute, but it does not eliminate fatigue, brain fog, unrefreshing sleep or post-exertional symptoms.
Working from home still requires reliable attendance, communication, decision-making and output.
The Insurer Uses Daily Activities Against You
Preparing a meal, attending an appointment or visiting family does not automatically prove that you can work full time.
The activity may be:
-
Completed slowly or with help
-
Performed only occasionally
-
Scheduled around periods of rest
-
Followed by a significant symptom crash
The Insurer Relies on Surveillance
An insurer may use short observations to argue that your activity level is greater than reported.
A brief video does not necessarily show the effort involved, the symptoms experienced afterward or whether the activity can be repeated the following day.
Read our guide to surveillance in long-term disability claims.
A Failed Return to Work Is Used Against You
A brief return or modified work attempt does not necessarily prove that employment is sustainable.
A medically supported but unsuccessful attempt may show that the hours, duties, cognitive demands or recovery requirements exceeded your capacity.
Your Benefits Are Cut Off After Two Years
Many LTD policies change their definition of disability after approximately two years.
The insurer may accept that you can’t return to your previous job but argue that you can perform another occupation.
It should consider whether your fatigue, post-exertional symptoms, brain fog and unreliable attendance allow you to perform another realistic occupation based on your education, training and experience.
Learn more about the LTD change of definition.
What Evidence Supports a Chronic Fatigue Disability Claim?
A strong claim should document your symptoms, treatment, functional restrictions and occupational demands over time.
Helpful evidence may include:
-
Clinical notes from your family doctor
-
Reports from relevant specialists
-
Investigations used to assess other possible causes of fatigue
-
Documentation of post-exertional malaise
-
Evidence of unrefreshing sleep and cognitive limitations
-
Records of dizziness or orthostatic symptoms
-
Medication and treatment history
-
A detailed description of your occupational duties
-
Attendance records and reduced-hours history
-
Failed accommodations, rehabilitation or return-to-work attempts
Document the Activity-and-Recovery Cycle
A symptom and activity record can help show:
-
The physical or mental activity performed
-
How long the activity lasted
-
When symptoms began to worsen
-
How severe the increase became
-
How long recovery required
Document Cognitive Function
Explain how brain fog affects reading, memory, processing speed, decisions, communication and completing multi-step tasks.
Document Attendance and Reliability
The ability to perform occasional activity is different from the ability to attend work on a fixed schedule.
Record missed days, shortened shifts, additional breaks and periods when symptoms made work impossible.
Address Your Complete Medical Condition
ME/CFS or chronic fatigue may occur alongside fibromyalgia, Long COVID, migraines, chronic pain, depression, anxiety or another condition.
The insurer should consider their combined effect instead of assessing each diagnosis in isolation.
What Happens After You Contact a Chronic Fatigue Disability Lawyer?
During an initial consultation, a disability lawyer may ask about your symptoms, treatment, occupation and the insurer’s reasons for denying or ending your benefits.
The lawyer may review:
-
Your denial or termination letter
-
The definition of disability in your policy
-
Your medical and treatment records
-
Your physical and cognitive job duties
-
Your accommodation and return-to-work history
-
Rehabilitation, functional or vocational assessments
-
Surveillance or social-media evidence
-
Important dates and potential legal deadlines
How Can a Chronic Fatigue Disability Claim Be Resolved?
Depending on the circumstances, a denied claim may be resolved through:
-
Reinstatement of monthly disability benefits
-
Payment of benefits previously withheld
-
A negotiated settlement
There is no standard chronic fatigue disability settlement. The outcome depends on the policy, monthly benefit, medical evidence, prognosis, age, occupation and other circumstances.

Frequently Asked Questions About Chronic Fatigue Disability Lawyers
What does a chronic fatigue disability lawyer do?
A lawyer reviews your insurance policy, denial letter and medical evidence and helps challenge an insurer’s refusal to pay benefits.
Can ME/CFS qualify for long-term disability?
Yes. ME/CFS may qualify when fatigue, post-exertional malaise, cognitive impairment or other symptoms prevent you from performing your occupation under the policy.
Can an insurer deny a claim because tests are normal?
An insurer may make that argument, but there is no single confirmatory test for ME/CFS. Normal testing does not independently establish work capacity.
Can chronic fatigue prevent sedentary work?
Yes. Sedentary work still requires concentration, attendance, communication and sustained cognitive effort.
Can an insurer force you into an exercise program?
Insurers may recommend rehabilitation, but any program should be medically appropriate and account for post-exertional symptom worsening.
Does a failed return to work hurt your claim?
Not necessarily. A medically supported but unsuccessful return may show that regular work was not sustainable.
Do you have to appeal directly to the insurer?
Not necessarily. An internal appeal is only one option. Speak with a disability lawyer before deciding how to challenge the denial.
How long do you have to challenge a denial?
Legal deadlines vary by province, policy and circumstances. Get legal advice promptly to protect your options.
