LTD Claims for Mental Health Conditions: Why They Get Denied and How to Fight Back 

Mental health conditions can be disabling. Depression, anxiety disorders, PTSD, bipolar disorder and other psychiatric or psychological conditions can affect concentration, memory, stamina, communication, judgment, attendance and the ability to tolerate workplace demands. 

Long-term disability claims for mental health conditions are often denied because the insurer says the medical evidence does not prove disability under the policy. A denial is not the same as a final legal determination. The denial letter should be reviewed carefully and the response should be strategic. 

Why Mental Health LTD Claims Are Denied in Ontario 

Insurers often deny mental health LTD claims by arguing that the evidence is not “objective” enough. Unlike a fracture or other visible injury, many mental health conditions are proven through clinical records, treatment history, medication records, specialist reports, psychological testing where available and evidence of functional impairment. 

A diagnosis alone is usually not enough. The key issue is function: how the condition prevents the claimant from performing the essential duties of their occupation under the policy. 

Common reasons for denial include: 

• insufficient medical documentation; 

• limited treatment history; 

• lack of specialist support; 

• inconsistent clinical notes; 

• surveillance or social media evidence; 

• a conclusion that the claimant can return to work with accommodation; 

• a finding that the claimant does not meet the policy definition of disability. 

The insurer’s conclusion should be tested against the policy wording and the actual medical record. 

Function Matters More Than the Label 

A strong LTD claim explains what the claimant cannot reliably do. 

For example, the evidence should address whether the person can sustain attention, meet deadlines, attend work consistently, interact appropriately with others, manage stress, make decisions and perform work at a reliable pace. 

The legal and medical focus should not be limited to the diagnosis. Two people with the same diagnosis may have very different levels of impairment. The claim must connect symptoms to workplace function. 

Stigma Can Affect the Claims Process in Ontario

Mental health disabilities are not always visible. A claimant may attend appointments, speak calmly during a call or have occasional good days. That does not mean they can sustain full-time work. 

Insurers sometimes place too much weight on isolated activities and too little weight on the overall medical picture. The proper analysis should consider the claimant’s symptoms, treatment, functional limits, relapse risk and ability to work reliably over time. 

Surveillance and Social Media Evidence 

Insurers may review public social media, request activity information or rely on surveillance. This evidence can be misleading if it shows only brief moments without context. 

A short video, a photo or an isolated public outing does not necessarily prove work capacity. Disability must be assessed against the policy wording, the medical evidence and the claimant’s ability to perform job duties functionally to approximately 60% of the pre-disability capacity. 

If surveillance is raised, the response should address context, duration, frequency, symptoms before and after the activity, and whether the activity is actually inconsistent with the medical restrictions. 

Evidence That Can Strengthen a Mental Health LTD Claim in Ontario

Strong evidence may include: 

• clinical records from a family doctor; 

• psychiatrist, psychologist, psychotherapist, social worker, or counsellor records; 

• medication history and treatment plans; 

• specialist referrals and reports; 

• hospital or crisis records where applicable; 

• records of functional limitations; 

• workplace accommodation history; 

• statements from people who have observed the claimant’s limitations; 

• a clear explanation of why the claimant cannot perform the essential duties of the job. 

The evidence should be specific. General statements that someone is “off work due to stress” are usually not enough. The medical record should explain symptoms, restrictions, limitations, treatment, prognosis and work capacity. 

What To Do After an LTD Denial in Ontario 

Start with the denial letter. Identify the reason for denial, the policy definition being applied, the evidence the insurer relied on and any deadline to respond. 

Do not send a rushed appeal that simply repeats the original claim. A strong response addresses the insurer’s reasons directly and fills the evidentiary gaps. 

Depending on the circumstances, the next step may be an internal appeal, a legal demand, a complaint process or litigation. The best option depends on the policy, the denial letter, the limitation period, and the evidence. 

Employees should also be careful in communications with the insurer. Emails, forms, phone calls, and social media content may become part of the claim file.

LTD Claims for Mental Health Conditions: How to Fight Back

What should I do if LTD is denied? 

Review the denial letter immediately and identify any deadlines. Do not assume the insurer is correct. The response should address the reasons for denial and may require updated medical records, specialist reports, and clearer evidence of functional limitations.

What is the most approved mental illness for disability in Ontario? 

There is no mental illness that is automatically approved. LTD entitlement depends on the policy wording and how the condition affects the person’s ability to work. Depression, anxiety disorders, PTSD, bipolar disorder, and other mental health conditions may support a claim if the evidence proves disability under the policy.

Is mental health a reason for long-term disability in Ontario? 

Yes. A mental health condition can support long-term disability benefits if it prevents the claimant from working and is supported by medical evidence. The central issue is functional impairment, not just the diagnostic label.

Do stress and anxiety qualify for long-term disability?

They can, depending on severity, medical support, and functional impact. Ordinary workplace stress may not be enough on its own. A diagnosed anxiety disorder, severe depression, PTSD, or another medically supported condition may qualify where it prevents the person from performing the essential duties of their job.
