For individuals navigating serious health challenges, accessing long-term disability (LTD) benefits can be essential to maintaining financial stability. A long term disability insurance lawyer in Ottawa can help clients understand their rights, but it’s helpful to know which conditions most commonly qualify for LTD coverage. From physical impairments to mental health disorders, here are the most frequent conditions that lead to approved long-term disability claims.

Debilitating Musculoskeletal Disorders
Musculoskeletal conditions are among the most cited reasons for LTD claims. These include chronic back pain, arthritis, degenerative disc disease, fibromyalgia, and severe joint issues. These disorders often limit mobility and reduce a person’s ability to perform physical tasks, especially in labor-intensive roles. Even in sedentary jobs, ongoing pain and restricted movement can make work unmanageable.
LTD insurers typically require extensive medical documentation, including diagnostic imaging, specialist evaluations, and records of treatment attempts such as physical therapy or medication management. If these efforts fail to provide relief, the condition may be considered a valid basis for long-term disability.
Mental Health Conditions with Lasting Effects
Mental health disorders such as major depressive disorder, generalized anxiety disorder, bipolar disorder, and PTSD are increasingly recognized in LTD claims. While these conditions may not have visible symptoms, they can significantly impair daily functioning, concentration, and social interaction, all of which are crucial in many work settings.
Insurance companies often scrutinize mental health claims more than physical ones, requiring ongoing psychological or psychiatric treatment and proof that symptoms persist despite therapy or medication. Consistent documentation from mental health professionals is essential for establishing credibility in a claim.
Severe Cardiovascular and Respiratory Diseases
Chronic heart conditions and respiratory diseases also account for a substantial portion of long-term disability claims. Heart failure, coronary artery disease, and complications from strokes can severely limit physical stamina. Similarly, diseases like COPD, severe asthma, or pulmonary fibrosis can reduce lung capacity to the point where basic activities become exhausting.
Medical tests such as stress tests, pulmonary function exams, and specialist reports are typically used to validate these claims. Individuals with these conditions may also experience secondary issues like fatigue or depression, which further impact employability.
Autoimmune and Chronic Illnesses
Autoimmune diseases such as lupus, rheumatoid arthritis, and multiple sclerosis often involve flare-ups that can be unpredictable and debilitating. These conditions may involve widespread inflammation, cognitive issues, chronic fatigue, or mobility impairments.
Chronic illnesses like Crohn’s disease or chronic fatigue syndrome also fall into this category. Despite sometimes being less visible, they can make it nearly impossible to maintain consistent work attendance and performance. Objective test results, specialist care, and treatment history are vital to support these types of claims.
Cancer and Treatment Complications
Cancer doesn’t just affect the body; it often disrupts every aspect of a person’s life. Beyond the disease itself, treatments such as chemotherapy, radiation, and surgery can leave individuals weak, nauseous, or cognitively impaired. In many cases, even remission doesn’t mean a full return to previous functionality.
Long-term disability policies typically cover cancer diagnoses, especially when the side effects of treatment extend beyond the typical short-term recovery period. Oncologist reports and detailed treatment records play a key role in these applications.
Conclusion
Qualifying for LTD benefits often involves more than just having a diagnosis—it requires comprehensive, ongoing evidence that the condition prevents meaningful employment. Understanding which conditions most often meet that standard can help individuals and their advocates build stronger cases and protect long-term stability.
