Migraine can qualify as a disability in Canada when recurring attacks, pain, vertigo, visual disturbances or cognitive symptoms prevent you from working safely and consistently.
Migraine is more than an ordinary headache. An attack may involve severe pain, nausea, sensitivity to light or sound, dizziness, visual changes and difficulty concentrating. Symptoms may continue before or after the headache itself.
A diagnosis alone does not automatically qualify you for disability benefits. Your insurer must consider the frequency, duration and severity of your attacks, your response to treatment and whether you can maintain regular attendance and productivity.
If your short-term or long-term disability claim has been denied or cut off, the disability lawyers at Samfiru Tumarkin LLP can review the insurer’s decision during a free consultation.

Is Migraine Considered a Disability in Canada?
Yes. Migraine can be considered a disability when its symptoms substantially limit your ability to work or complete important daily activities.
Potentially disabling symptoms include:
-
Severe or throbbing head pain
-
Nausea and vomiting
-
Sensitivity to light, noise or smells
-
Blurred vision, flashing lights or other aura symptoms
-
Dizziness, vertigo or loss of balance
-
Difficulty concentrating or processing information
-
Fatigue and cognitive fog after an attack
Is Migraine a Permanent Disability?
Migraine is a recurring neurological condition, but its frequency and effect on employment may change over time.
Treatment may reduce the number or severity of attacks without eliminating them. You do not have to prove that you will never improve or work again.
You may qualify for disability benefits for as long as migraine prevents you from working under the terms of your policy.
Can Episodic Migraine Be Disabling?
Yes. Even attacks that occur several times per month may be disabling when they are severe, lengthy or unpredictable.
The insurer should consider the complete attack cycle, including aura, headache symptoms and the fatigue or cognitive problems that may continue afterward.
What Types of Migraine Can Qualify for Disability?
Any form of migraine may support a disability claim when its symptoms prevent reliable work.
Chronic Migraine
Chronic migraine generally involves headaches on at least 15 days per month for more than three months, with migraine features on at least eight of those days.
Frequent attacks, recovery periods and medication effects may leave few consistently productive days each month.
Vestibular Migraine
Vestibular migraine can cause recurring vertigo, dizziness, nausea, sensitivity to movement and balance problems.
These symptoms may interfere with driving, screen use, walking, operating machinery or working in visually busy environments. Head pain may not be the main symptom during every episode.
Migraine With Aura
Aura may involve visual, sensory, speech or language symptoms before or during an attack.
Flashing lights, blind spots, numbness or difficulty communicating may prevent driving, reading, decision-making and other safety-sensitive duties.
Hemiplegic Migraine
Hemiplegic migraine is a rare form of migraine that can cause temporary weakness on one side of the body alongside other aura symptoms.
Recurring weakness, speech difficulties or visual changes can create significant safety and attendance limitations.
How Can Migraine Affect Your Ability to Work?
Migraine can affect physical, office, professional, customer-facing and safety-sensitive occupations.
Attendance and Reliability
Attacks may begin with little warning and last for hours or days. You may need to stop working, leave the workplace or remain in a dark and quiet space.
Even when you can work between attacks, unpredictable absences may prevent you from meeting the normal attendance requirements of your job.
Concentration and Communication
Pain, aura and cognitive symptoms may interfere with reading, memory, decision-making and verbal communication.
These limitations can affect detailed office work, professional judgment, meetings and interactions with clients or coworkers.
Light, Noise and Workplace Triggers
Bright or flickering lights, computer screens, noise, strong scents, missed meals and irregular schedules may trigger or worsen attacks.
Possible accommodations include adjusted lighting, scent-free policies, flexible hours, scheduled breaks, remote work and access to a quiet space.
Accommodation may not be enough when attacks remain frequent and unpredictable.
Driving and Safety-Sensitive Work
Visual disturbances, dizziness, weakness and slowed concentration may make driving, operating machinery or working at heights unsafe.
The ability to perform these duties between attacks does not resolve the risk of sudden symptoms.
Can You Work From Home With Migraine?
Remote work may reduce exposure to commuting, lighting and noise, but it does not eliminate migraine.
Screen use, cognitive demands and virtual meetings may remain impossible during an attack or recovery period.
Can You Get Disability Benefits for Migraine?
You may qualify for disability benefits when migraine prevents you from performing the essential duties of your occupation.
Short-Term Disability Benefits
Short-term disability benefits may replace part of your income during a severe increase in attacks, treatment changes or a medically supported period away from work.
Long-Term Disability Benefits
Long-term disability benefits may become available when migraine continues to prevent you from working beyond the short-term disability period.
Many LTD policies initially consider whether you can perform your own occupation. Later, the insurer may assess whether you can perform another suitable occupation.
The insurer should consider whether recurring attacks allow you to maintain the attendance, concentration and productivity required by another job.
CPP Disability Benefits
You may qualify for CPP Disability benefits if migraine and your complete medical condition regularly prevent substantially gainful work.
Your disability must generally be long-term or indefinite, and you must have made enough valid CPP contributions.
Disability Tax Credit for Migraine
Migraine does not automatically qualify for the Disability Tax Credit.
Eligibility depends on whether migraine causes severe and prolonged limitations in an eligible everyday activity or significant limitations in multiple categories whose cumulative effect meets the CRA’s requirements.

How Do You Prove a Migraine Disability Claim?
Migraine is generally diagnosed using your symptoms and medical history. Detailed and consistent documentation is therefore especially important.
Helpful evidence may include:
-
Records from your family doctor, neurologist or headache specialist
-
A diary showing attack frequency, duration and severity
-
Aura, vertigo, nausea and cognitive symptoms
-
Your medication and preventive-treatment history
-
Medication side effects
-
Emergency-room visits or urgent treatment
-
A detailed description of your occupational duties
-
Failed accommodations or return-to-work attempts
Keep a Migraine Diary
Record when each attack begins, how long it lasts, the symptoms involved, medication taken and the activities you are unable to complete.
Include recovery time and the number of workdays that are missed or significantly affected.
What Is a Migraine Disability Assessment?
Tools such as the Migraine Disability Assessment questionnaire, commonly called MIDAS, and the Headache Impact Test can help measure how headaches affect work, household activities and daily life.
These assessments may support your medical records, but a score does not automatically determine whether an insurer must approve benefits.
Document Failed Treatment
Insurers may expect you to try reasonable treatments recommended by your doctors.
Document preventive medications, acute treatments, injections or other therapies, including whether they were ineffective or caused side effects.
Why Do Insurers Deny Migraine Disability Claims?
An insurer may accept that you experience migraine but argue that the evidence does not prove you are unable to work.
Common denial reasons include:
-
Brain imaging and neurological examinations appear normal
-
Pain and other symptoms are described as subjective
-
The insurer says medication should control the attacks
-
Your medical records do not document attack frequency
-
The insurer focuses on activities completed between attacks
-
The insurer says you can perform sedentary or remote work
The Insurer Says Your Tests Are Normal
Migraine may not produce an abnormal MRI, CT scan or neurological examination between attacks.
Testing may be used to exclude other causes without measuring the severity or frequency of your migraine symptoms.
The Insurer Says Medication Should Work
Treatment helps many people without fully controlling every attack.
Your evidence should document the medications and treatments attempted, the results and any limiting side effects.
The Insurer Uses Your Good Days Against You
Completing errands or activities between attacks does not prove that you can maintain a full-time work schedule.
The insurer should consider your attack frequency, lost days and ability to remain consistently available.
What Should You Do After a Denial?
Save the denial letter, continue receiving appropriate treatment and request a complete copy of your disability policy.
Speak with a disability lawyer before filing an internal appeal. The same insurer that denied your claim will review it, and legal deadlines may continue to run.

Frequently Asked Questions About Migraine and Disability
Is migraine considered a disability in Canada?
Migraine can be considered a disability when recurring attacks substantially affect your ability to work or complete important daily activities.
Can chronic migraine qualify for long-term disability?
Yes. Chronic migraine may qualify when frequent attacks prevent you from performing your occupation or another suitable occupation under your policy.
Can vestibular migraine qualify for disability?
Potentially. Vertigo, dizziness and balance problems may prevent safe and reliable work even when headache is not the dominant symptom.
Can migraine qualify if an MRI is normal?
Yes. Migraine is generally diagnosed through symptoms and medical history. Normal imaging does not automatically establish work capacity.
Can migraine qualify for CPP Disability?
It may qualify when migraine and your complete medical condition regularly prevent substantially gainful work and meet the CPP requirements.
Should you appeal a denied migraine claim?
Do not assume an internal appeal is the best option. Speak with a disability lawyer before deciding how to challenge the insurer.
