Are Sleep Disorders Considered a Disability?

Most people have trouble sleeping from time to time. A few bad nights can leave you tired and frustrated. Usually, the problem goes away.

For some people, it does not.

Sleep disorders can affect almost every part of life. They can make it hard to work, drive, focus, remember information, and complete everyday tasks. Some people feel exhausted all day. Others struggle to fall asleep or stay asleep. Some experience sudden sleep attacks or breathing problems during the night.

When a sleep disorder becomes severe, it may be considered a disability under Canadian law.

This can be important. People living with disabling sleep disorders may have rights to workplace accommodations. Depending on their circumstances, they may also qualify for long-term disability benefits, CPP Disability benefits, or other forms of support.

Across Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador, people living with serious sleep disorders have legal protections. Human rights laws protect people from discrimination based on disability. However, the legal test for disability can be different depending on whether the issue involves human rights, workplace accommodation, private disability insurance, CPP Disability benefits, or a personal injury claim.

Knowing which rules apply can help you understand your rights and the support that may be available.

What Is a Sleep Disorder?

A sleep disorder is a medical condition that affects a person’s ability to get healthy sleep.

Some sleep disorders make it hard to fall asleep. Others interrupt sleep throughout the night. Some cause extreme tiredness during the day.

Common sleep disorders include:

• Sleep apnea;
• Narcolepsy;
• Chronic insomnia;
• Restless legs syndrome;
• Shift work sleep disorder;
• Circadian rhythm sleep disorders;
• REM sleep behaviour disorder;
• Hypersomnia disorders; and
• Sleepwalking and other parasomnias.

Some sleep disorders are mild. Others are severe.

A person with a mild condition may have only minor symptoms. Another person with the same diagnosis may struggle to work, drive, or complete daily activities.

That is why the diagnosis is usually only part of the picture. In disability benefit claims, the focus is often on how the person’s symptoms affect their ability to function and work.

Can a Sleep Disorder Be a Disability?

Yes, a sleep disorder can be considered a disability in Canada, depending on the condition and the legal context.

For human rights purposes, the definition of disability is generally broad. A sleep disorder may therefore receive human rights protection even if it does not completely prevent someone from working.

Disability benefit claims are different. For long-term disability or CPP Disability benefits, the person must also satisfy the specific eligibility test that applies to those benefits.

Depending on the claim, a sleep disorder may be considered disabling if it:

• Makes it hard to safely or reliably work;
• Causes serious fatigue;
• Creates safety concerns;
• Affects memory or concentration;
• Causes difficulty maintaining regular attendance;
• Limits daily activities; and
• Requires ongoing treatment or has ongoing symptoms despite appropriate treatment.

For example, a person with severe narcolepsy may have trouble staying awake during the day. Someone with sleep apnea may continue to experience significant fatigue and concentration problems despite appropriate treatment.

In both situations, the condition may affect the person’s ability to work and function normally. Whether that results in legal protection or entitlement to benefits depends on the particular legal test being applied.

How Is Disability Defined?

There is no single definition of disability that applies to every situation. This is an important distinction.

For human rights purposes, disability is interpreted broadly. A person does not necessarily have to be completely unable to work before being protected from disability-related discrimination.

Long-term disability insurance is different. Eligibility depends on the wording of the person’s insurance policy and whether their condition meets that policy’s definition of disability.

CPP Disability has its own legal test. A person must have a disability that is both “severe” and “prolonged” and must satisfy the other CPP eligibility requirements.

Many people think there is a list of conditions that automatically count as disabilities, but this is generally not the case. Whether someone has a disability is primarily determined on an individual basis.

This means two people with the same diagnosis can have very different claims. One person may have mild symptoms that respond well to treatment. Another may continue to struggle every day. The second person may be more likely to qualify for benefits because the condition has a greater effect on their life.

Depending on the type of claim, decision-makers may consider questions such as:

• Can the person work safely?
• Can they stay awake during the day?
• Can they focus and complete tasks?
• Can they attend work regularly and reliably?
• Can they perform the important duties of their job?
• Have reasonable treatments been tried?
• How long are the limitations expected to continue?

The diagnosis matters, but its real-world effects and the answers to the above questions are often critical.

Your Rights in Atlantic Canada

People with sleep disorders that amount to disabilities may be protected by human rights laws.

These laws protect people from discrimination because of disability and can require employers and others to reasonably accommodate disability-related needs in many situations.

Although the wording of the legislation differs between provinces, the basic principles and overall protections are similar.

It is also important to know that some workplaces and services are federally regulated. In those cases, the Canadian Human Rights Act may apply instead of provincial human rights legislation.

Nova Scotia

The Nova Scotia Human Rights Act protects people from discrimination based on physical and mental disability.

The Act applies in areas including employment, housing, services, and other protected areas of public life.

New Brunswick

The New Brunswick Human Rights Act provides similar protection against discrimination.

Employers must consider reasonable accommodations for workers with disabilities.

Prince Edward Island

The Prince Edward Island Human Rights Act also protects people from discrimination based on disability.

Workers with disabilities may be entitled to reasonable workplace accommodations, depending on their individual circumstances and the requirements of their job.

Newfoundland and Labrador

The provincial Human Rights Act protects people from disability-related discrimination in Newfoundland and Labrador.

Like the other Atlantic provinces, the law requires reasonable accommodation in many situations up to the point of causing undue hardship on the employer.

What Is the Duty to Accommodate?

Many people have heard the phrase “duty to accommodate”.

In the workplace, it generally means that an employer must consider reasonable changes that would allow an employee with a disability to participate in the workplace without discrimination. Simply put, it means employers cannot automatically refuse to hire someone, fire someone, or treat them unfairly because of a disability.

An employer cannot simply ignore disability-related needs; they must look for reasonable solutions. At the same time, an employee is not necessarily entitled to the exact accommodation they request.

Possible accommodations may include:

• Flexible schedules;
• Changes to shifts;
• Additional or modified breaks;
• Remote work, where appropriate;
• Modified duties;
• Changes to the workplace or equipment; and
• Temporary leave.

For example, a worker with a serious sleep disorder may need a temporary schedule change while treatment is being adjusted. A worker with narcolepsy may need changes to duties or scheduling that reduce safety risks.

Every case is different.

The employer, employee, and sometimes the employee’s union all have roles in the accommodation process. An employer may also be entitled to appropriate medical information about the employee’s functional restrictions, limitations, prognosis, and accommodation needs.

The duty to accommodate continues only to the point of undue hardship. Factors such as significant cost, workplace disruption, and legitimate health and safety concerns may be relevant.

Is Sleep Apnea a Disability?

It can be.

Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep. The most common type is obstructive sleep apnea, which occurs when the airway becomes blocked during sleep. Many people with sleep apnea do not realize how often their sleep is interrupted.

Common symptoms can include:

• Loud snoring;
• Gasping or choking during sleep;
• Morning headaches;
• Poor concentration;
• Memory problems;
• Daytime fatigue; and
• Irritability.

Many people improve significantly with treatment such as a CPAP machine. Others may continue to experience symptoms despite treatment, or may have difficulty finding an effective treatment.

For human rights purposes, sleep apnea may amount to a disability depending on the circumstances, such as when it causes ongoing fatigue, concentration problems, or difficulty working. 

For disability benefits, a diagnosis of sleep apnea by itself does not automatically establish entitlement. The person’s symptoms, treatment, functional limitations, work requirements, and the particular legal or insurance test will all matter.

For example, fatigue may have a very different impact on an office worker than on someone whose job involves commercial driving or operating heavy machinery.

Is Narcolepsy a Disability?

In many cases, yes.

Narcolepsy is a neurological condition that affects the brain’s sleep-wake cycle.

People with narcolepsy often feel extremely tired during the day. Some experience sudden sleep attacks. Others experience cataplexy, which involves episodes of sudden muscle weakness.

Symptoms can include:

• Excessive daytime sleepiness;
• Sudden sleep attacks;
• Cataplexy;
• Sleep paralysis;
• Hallucinations when falling asleep or waking up; and
• Difficulty staying alert.

Narcolepsy can affect many areas of a person’s life.

Some people may struggle to work full-time or regularly show up. Others may be unable to safely perform certain duties or jobs involving driving, machinery, heights, or other safety-sensitive work.

Whether narcolepsy qualifies a person for LTD or other disability benefits depends on the severity of the symptoms and the applicable definition of disability. Because the condition can create serious limitations, disability insurers often recognize severe narcolepsy as a disabling condition.

Strong medical evidence is important. Medical providers should document not only the diagnosis but also the person’s symptoms, treatment, restrictions, limitations, and ability to function at work.

Can Insomnia Be a Disability?

Chronic insomnia can also amount to a disability in some circumstances.

Insomnia is more than an occasional bad night of sleep; it involves ongoing difficulty falling asleep, staying asleep, or getting restful sleep.

Over time, chronic insomnia can lead to:

• Fatigue;
• Poor concentration;
• Memory problems;
• Mood changes;
• Anxiety;
• Depression; and
• Reduced productivity.

Some people continue to function reasonably well despite insomnia. Others find that poor sleep affects nearly every part of their lives.

A person who consistently gets very little sleep may struggle to focus at work, learn new information, complete tasks efficiently, or maintain regular job attendance.

When insomnia creates serious daily challenges, it may support a disability claim, depending on the definitions laid out within the applicable insurance policy or benefit program.

Other Sleep Disorders That May Qualify

Sleep apnea, narcolepsy, and insomnia are not the only sleep disorders that may qualify as disabilities.

Other conditions can also create serious limitations.

Examples include:

• Restless legs syndrome;
• Shift work sleep disorder;
• Circadian rhythm sleep disorders;
• REM sleep behaviour disorder; and
• Hypersomnia disorders.

Regardless of the diagnosis, the same question usually applies.

How much does the condition affect the person’s daily life? If the answer is “a great deal,” disability benefits or legal protections may be available.

Sleep Disorders and Long-Term Disability Benefits

Many people receive disability insurance through work.

This coverage is often called long-term disability insurance, or LTD.

LTD benefits may be available when illness or injury meets the definition of disability contained in the person’s insurance policy. This point is important: there is no single definition of disability that applies to every LTD policy.

Sleep disorders may qualify for LTD benefits when symptoms are severe enough to stop someone from performing their job.

Insurance companies usually focus on how the condition affects work capacity. They may consider evidence such as:

• Medical records;
• Sleep study results;
• Specialist reports;
• Treatment history;
• Medication history;
• Functional limitations;
• Job duties; and
• Attendance and work records.

If you are applying for LTD benefits, take the application process seriously from the beginning. The quality and consistency of the evidence can be very important. Typically, the stronger the evidence, the stronger the claim.

The Own Occupation Period

Most LTD policies start with an “own occupation” test. The exact wording varies by policy. Generally, the insurer considers whether the claimant is unable to perform the important or essential duties of their regular job because of illness or injury.

For example, a truck driver with uncontrolled narcolepsy may not be able to safely perform their job duties. A nurse experiencing severe fatigue and concentration problems may face different but equally important functional limitations.

If the evidence supports that the sleep condition prevents the person from doing their own job, benefits may be approved.

The Any Occupation Period

Many LTD policies later switch to a stricter definition of disability, often after about 24 months of benefits. This is commonly called the “any occupation” test.

Though the wording varies, the insurer is essentially then asking a different question: can the claimant perform any other job that reasonably matches their education, training, and experience? Some policies also include requirements relating to the level of income available from another occupation.

This change in definition oftentimes leads to disputes.

An insurer may agree that someone cannot return to their previous job but take the position that they are capable of performing another type of work. For this reason, medical, functional, vocational, and occupational evidence can become particularly important at this stage.

Why Are Sleep Disorder Claims Denied?

Many people expect that a diagnosis will be enough. Unfortunately, that is not always true. A diagnosis does not automatically establish entitlement to disability benefits.

Sleep disorder claims may be denied for reasons such as:

• Not enough medical evidence;
• A lack of evidence showing functional limitations;
• Failure to follow treatment advice;
• Questions about work capacity;
• Conflicting medical opinions;
• Evidence suggesting the person’s symptoms have improved; or
• Failure to meet the particular definition of disability in the policy.

For example, an insurer may accept that a person has sleep apnea but argue that treatment allows them to continue working. An insurer may accept a diagnosis of insomnia but argue that the condition is not severe enough to prevent the person from performing their occupation.

Many disability disputes therefore focus less on whether the diagnosis exists and more on what the medical condition actually prevents the person from doing.

Medical Evidence Matters

Medical evidence is often one of the most important parts of a disability claim—if not the most important part.

Good records help explain the condition and how it affects the person’s daily life and ability to work.

Helpful evidence may include:

• Sleep studies;
• Family doctor records;
• Specialist reports;
• Medication records;
• Treatment records; and
• Functional assessments.

Medical records should do more than simply confirm a diagnosis; they should also document relevant symptoms and limitations.

Showing How the Condition Affects You

Many disability claims succeed or fail based on one practical question: What does the condition actually prevent the person from doing?

An insurer may consider questions such as:

• Can the person work a full day or full week?
• Can they attend work regularly and predictably?
• Can they remain awake and alert?
• Can they focus on tasks?
• Can they work at an acceptable pace?
• Can they perform their job safely?
• Can they reliably perform the important duties of their occupation?

A diagnosis is important. However, evidence showing daily challenges is often just as important. That is why detailed medical records, work records, and symptom notes can be so helpful.

Poor Sleep Can Affect More Than Energy

Poor sleep affects more than energy levels.

Over time, sleep disorders can affect memory, concentration, mood, and overall health. Some people also develop related conditions such as anxiety, depression, high blood pressure, or heart disease.

When disability claims are assessed, the combined effect of all of a person’s medical conditions may be important.

CPP Disability Benefits and Sleep Disorders

Some people with severe sleep disorders may qualify for Canada Pension Plan (CPP) Disability benefits.

CPP Disability benefits are available to people who can no longer work because of a serious medical condition. CPP Disability has a specific legal test. To qualify, a person must have a disability that is both severe and long-term, must meet the CPP contribution requirements, and must satisfy the other eligibility requirements.

For CPP purposes, a disability is considered severe when it regularly prevents a person from working. A long-term disability is one that is expected to continue for the foreseeable future or is likely fatal. This is a stricter test than simply showing that a medical condition makes a person’s regular job difficult.

A sleep disorder does not automatically qualify someone for CPP Disability benefits.

However, some people with severe sleep apnea, narcolepsy, chronic insomnia, or other serious sleep disorders may qualify if the overall medical condition and functional limitations satisfy the CPP test.

What Does Service Canada Look At?

Decision-makers often review evidence including:

• Medical records;
• Sleep study results;
• Specialist reports;
• Treatment history;
• Work history;
• Functional limitations;
• Education and transferable skills; and
• The person’s ability to regularly perform sufficiently gainful work.

Decision-makers may also consider whether reasonable treatment has been pursued and whether treatment has improved or is expected to improve the person’s ability to function.

Sleep Disorders and Mental Health

Sleep disorders often occur alongside mental health conditions.

Many people with sleep disorders also experience:

• Anxiety;
• Depression;
• PTSD; or
• Chronic stress.

The relationship can work both ways. Poor sleep can worsen mental health symptoms, while mental health conditions can also interfere with sleep. 

When disability claims are reviewed, decision-makers often look at the combined effect of all medical conditions rather than looking at each diagnosis in isolation.

For example, a person with chronic insomnia and severe depression may face greater challenges than someone dealing with only one of those conditions.

Sleep Disorders After a Car Accident

Sleep problems are common after motor vehicle accidents.

Some people struggle to sleep because of pain. Others experience anxiety, nightmares, or emotional distress after a crash.

Common sleep problems after an accident may include:

• Insomnia;
• Nightmares;
• Anxiety-related sleep problems;
• PTSD-related sleep disturbances;
• Pain-related sleep disruption; and
• Excessive fatigue.

In many cases, sleep improves as the person recovers. In other cases, sleep problems continue for months or even years.

Poor sleep can also make other accident-related symptoms more difficult to manage. It may affect pain, mood, concentration, and the person’s ability to complete everyday activities.

When sleep problems are caused or worsened by an accident, they may form part of the damages claimed in a personal injury case. 

A separate formal sleep-disorder diagnosis is not necessarily required in every personal injury claim. However, there must still be evidence connecting the sleep problems to the accident and showing their nature, duration, and effect on the person’s life. Medical records can be important in establishing that connection.

Sleep Disorders After a Brain Injury

Sleep problems are also common after a concussion or traumatic brain injury.

People recovering from brain injuries may experience:

• Insomnia;
• Excessive daytime sleepiness;
• Broken or disrupted sleep;
• Fatigue; and
• Trouble staying alert.

Poor sleep may also worsen other symptoms, including headaches, memory problems, and concentration difficulties.

For this reason, sleep issues can become an important part of disability claims and personal injury claims involving brain injuries. As with any claim, the medical evidence and the connection between the injury and the ongoing symptoms are important.

Sleep Disorders and Safety at Work

Some jobs require workers to stay alert at all times.

This can create challenges for people living with serious sleep disorders.

Examples include:

• Truck drivers;
• Bus drivers;
• Pilots;
• Construction workers;
• Heavy equipment operators;
• First responders; and
• Health-care workers.

In these jobs or similar areas, excessive fatigue or unexpected sleep episodes can create legitimate safety concerns. Employers must balance safety with their duty to accommodate workers with disabilities.

Safety concerns do not automatically eliminate the duty to accommodate. The employer should consider the employee’s individual circumstances and whether reasonable accommodations can address the risk without causing undue hardship.

The appropriate solution will depend on the worker’s symptoms, medical restrictions, job duties, and available accommodations.

Steps You Can Take

If a sleep disorder is affecting your life, there are several practical steps you can take that may help.

Get Medical Treatment

Speak with your doctor and other healthcare providers and follow their treatment recommendations.

Regular medical care is important for your health and can also help document the condition if you later need disability benefits or workplace accommodations.

Keep Important Records

Save copies of documents such as:

• Sleep study reports;
• Medical records;
• Specialist reports;
• Treatment plans;
• Disability forms; and
• Communications with your insurer.

These records may become important if you apply for benefits or have a dispute with an insurer.

Track Your Symptoms

Consider keeping a journal and be accurate and consistent in using it.

Record your sleep patterns, fatigue levels, symptoms, and any problems you experience at work or at home.

Keep Notes About Work Problems

If your condition affects your job, keep records of things such as:

• Missed work;
• Reduced hours;
• Difficulty completing duties;
• Accommodation requests;
• Changes in job duties; and
• Workplace discussions.

These records may help explain how the condition is affecting your ability to work and could support a future claim.

When Should You Talk to a Lawyer?

Not every sleep disorder requires legal help.

However, speaking with a lawyer may be useful if:

• Your LTD claim was denied;
• Your CPP Disability application was denied;
• Your benefits were cut off;
• Your employer refused or failed to properly consider disability-related accommodations;
• You believe you were treated unfairly because of a disability; or
• Your sleep disorder developed or became worse after an accident.

Many disability disputes involve medical evidence, insurance policies, human rights obligations, and legal deadlines.

A lawyer can help you understand which rules apply to your situation and what options may be available.

Frequently Asked Questions

Is sleep apnea considered a disability in Canada?

It can be.

Severe sleep apnea that affects a person’s ability to work or carry out daily activities may be considered a disability depending on the circumstances.

Can I get long-term disability benefits for a sleep disorder?

Possibly.

Many people receive LTD benefits when a sleep disorder prevents them from doing their job and if their symptoms satisfy the definition of disability contained in their insurance policy.

The outcome depends on factors including the medical evidence, functional limitations, job duties, treatment history, and policy wording.

What if my disability claim is denied?

A denial does not necessarily mean the claim is weak or meritless. 

Depending on the type of claim, a person may be able to provide additional evidence, request a reconsideration or appeal, or pursue other legal remedies.

If your LTD or CPP Disability claim is denied, consider getting legal advice as soon as possible. There are deadlines for challenging disability benefit decisions, and those deadlines can differ depending on the type of claim and the stage of the process.

For CPP Disability, a request for reconsideration generally must be made within 90 days of receiving the decision. For LTD claims, appeal deadlines may be set out in the insurer’s denial letter or insurance policy, and separate legal limitation periods may also apply if a lawsuit is required.

Do not assume that an internal appeal or reconsideration automatically protects every other deadline. Getting legal advice early can help you understand why the claim was denied, what additional medical or vocational evidence may be needed, and what steps should be taken before an important deadline passes.

Conclusion

Sleep disorders are more than an inconvenience.

For some people, they make it difficult to work, drive, focus, or enjoy daily life.

Conditions such as sleep apnea, narcolepsy, chronic insomnia, and restless legs syndrome can sometimes qualify as disabilities.

Across Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador, people living with serious sleep disorders may have protections under human rights laws. Depending on their circumstances, they may also qualify for workplace accommodations, disability benefits, or other forms of support.

Every case is different.

The diagnosis matters, but so do the person’s symptoms, functional limitations, treatment, work duties, and the particular legal test that applies.

If a sleep disorder is affecting your ability to work or live independently, it is important to understand your rights and explore the support that may be available.
