When you apply for long-term disability (LTD) benefits, you expect your insurance coverage to provide financial support during a difficult time. Unfortunately, many Ontario residents have their LTD claims denied, even when their condition is legitimate. This can create stress, uncertainty, and significant financial pressure.
Insurance companies may deny claims for a range of reasons. In many cases, these denials can be challenged with the right approach and legal guidance. Understanding why disability claims are rejected is the first step in protecting your rights and strengthening your case.
Insufficient Medical Evidence
One of the most common reasons for a disability claim denial is insufficient medical evidence. Insurers frequently argue that the documentation provided does not clearly demonstrate how your condition prevents you from working.
Even where a diagnosis exists, insurance companies often require detailed descriptions of functional limitations. They may want to know how long you can sit, stand, or concentrate. Without clear, consistent medical support, a claim may be denied despite a legitimate condition.
Challenges Relating to the Definition of Disability
Most disability insurance policies have specific definitions of disability that change over time. During the first stage, you may need to show that you cannot perform your own job. Later, the standard often shifts to whether you can perform any job suited to your skills or experience.
This change is a common point where claims are denied or terminated. Insurers may argue that although you cannot return to your previous role, you are still capable of performing other types of work.
Missed Deadlines or Incomplete Applications
Strict timelines and documentation requirements apply to long-term disability claims. Missing deadlines, submitting incomplete forms, or failing to provide requested information can result in a denial.
Insurance companies rely heavily on procedural compliance. Even minor errors in your application can lead to delays or denial of benefits.
Pre-existing Condition Exclusions
Many policies include exclusions for pre-existing conditions. If your disability is linked to a medical issue you experienced before your coverage began, your claim may be denied based on policy terms.
These exclusions can be complex and depend on the wording of your insurance policy and the timing of your symptoms or treatment.
Surveillance and Credibility Concerns
Insurance companies sometimes conduct surveillance or review social media activity to assess claims. If they believe your daily activities contradict your reported limitations, they may deny your claim.
However, surveillance evidence can be misleading. A brief snapshot of activity does not necessarily reflect your ability to sustain full-time work.
Independent Medical Examinations
Insurers may require you to attend an independent medical examination. In some cases, these assessments lead to opinions that differ from your treating physician’s findings, which can be used to justify a denial.
When there are conflicting medical opinions, insurers may favour evidence that supports denying or limiting benefits.
Challenging an Unfair Denial
Ontario courts have recognized that insurers must handle disability claims fairly. In Kardaras v. Sun Life Assurance Company of Canada, 2020 ONSC 3925, the court found that the insurer wrongfully terminated benefits during a gradual return to work and failed to properly consider the claimant’s condition.
The court ordered compensation, including retroactive benefits and damages for mental distress. This case highlights that a denial is not always final and that legal action can lead to a successful outcome.
What to Do If Your LTD Claim Is Denied
If your LTD claim is denied, it is important to act quickly and carefully. A denial letter is not necessarily the end of your claim. Many decisions can be challenged through appeals or legal action.
Steps to consider include:
viewing the denial letter to understand the insurer’s reasoning
gathering additional medical evidence that clearly explains your limitations
keeping records of all communications with your insurer
consulting a disability claim denial lawyer before filing an appeal
In Ontario, strict limitation periods apply, and waiting too long could impact your ability to pursue a claim.
