Long-Term Disability Denied? 5 Steps to Challenge an LTD Denial in Ontario 

A long-term disability denial can create immediate financial pressure. If you cannot work because of an illness, injury, mental health condition, chronic pain, or another disabling condition, LTD benefits may be the income bridge that allows you to focus on treatment and recovery. 

A denial does not necessarily end your claim. Insurers can deny valid claims because they say the medical evidence is incomplete, the policy definition is not met, the employee can return to work, or the claim fails at the change from the “own occupation” test to the “any occupation” test. The next step must be handled carefully because deadlines, policy wording, and limitation periods can affect your rights. 

Step 1: Read the Denial Letter Carefully 

Start with the denial letter. It should explain why the insurer refused the claim and identify any internal appeal deadline. Read the letter against the policy, not in isolation. 

Common reasons for LTD denial include: 

• Insufficient medical evidence 

• A finding that you do not meet the policy’s definition of disability 

• Missed proof-of-claim or appeal deadlines 

• Surveillance or social media evidence 

• The insurer’s position that you can return to your own occupation or another occupation 

• A change in the disability test after a defined period under the policy 

Do not assume the insurer’s explanation is complete or correct. The denial may be based on a selective review of the medical file, a misunderstanding of your job duties or an overly narrow view of your restrictions and limitations. 

Step 2: Confirm Every Deadline in Ontario

Disability policies often include strict deadlines for submitting proof of claim, appealing a denial and starting a legal claim. Missing a deadline can create serious problems. 

An internal appeal deadline is not the only timeline that matters. In some cases, pursuing internal appeals may not stop a limitation period from running. Before sending further information to the insurer, confirm the policy deadline, the denial date and any legal limitation issue that may apply. 

This is one of the main reasons to obtain legal advice early. A lawyer can assess: whether an internal appeal is worth pursuing, whether the insurer’s denial is plain and final, and whether a lawsuit or negotiated resolution should be considered instead. 

Step 3: Build Medical Evidence Around Function, Not Just Diagnosis 

Medical evidence is usually the heart of an LTD dispute. A diagnosis alone may not be enough. The insurer will usually look for evidence explaining how your symptoms affect your ability to perform your job duties or other suitable work at a later stage. 

Useful evidence may include: 

• Updated reports from treating physicians and specialists 

• Clinical notes and records 

• Medication history and side effects 

• Functional assessments 

• Treatment history and referrals 

• Evidence of restrictions, limitations, flare-ups, and prognosis 

• A clear description of your actual job duties and why you cannot perform them 

A short note saying you are “unable to work” is often insufficient. Connect the medical condition to functional limitations in a clear, detailed and work-specific way. 

Step 4: Be Careful With the Internal Appeal Process in Ontario

Many employees assume they must complete the insurer’s internal appeal process before taking any other step.  

However, an internal appeal may be useful where the denial is based on missing information, incomplete records or a correctable misunderstanding. It may be less useful where the insurer has taken a firm position, repeatedly requested the same information or maintained a denial despite strong medical support. 

Before appealing, consider whether the insurer has all relevant medical evidence, whether new evidence will materially change the analysis, whether the appeal deadline is realistic and whether a legal claim should be started instead. The strategy should be driven by the policy, the denial letter, the evidence and the applicable deadline. 

Step 5: Get Advice Before the Dispute Drags On 

LTD disputes can become harder when months pass without income. Insurers may continue to request more information, send you for assessments, rely on surveillance or maintain the denial even after receiving additional records. 

Legal advice can help you identify what evidence is missing, whether the denial is vulnerable, what deadlines apply, and what the claim may be worth. It can also help avoid a common mistake: spending months in internal appeals while the legal deadline continues to move closer.

Long-Term Disability Denied? Steps to Challenge an LTD Denial in Ontario 

What is the best way to appeal a disability claim in Ontario?

The best approach is to review the denial letter, confirm all deadlines, compare the denial against the policy wording, and submit medical evidence that explains your functional limitations. Before appealing, obtain advice on whether an internal appeal is the right strategy or whether another legal step is required.

What is the hardest disability to get approved for in Ontario?

There is no single condition that is always the hardest to approve. Claims involving chronic pain, mental health conditions, fatigue-related illnesses, and fluctuating symptoms can be more difficult because restrictions may be harder to measure. Strong, detailed medical evidence is essential.

What are common reasons for an LTD denial? 

Common reasons include insufficient medical evidence, missed deadlines, the insurer’s view that the policy definition of disability is not met, surveillance, independent medical assessments, or the insurer’s position that you can return to work.

Do you have to complete an internal appeal before suing an LTD insurer from Ontario?

Not necessarily. The answer depends on the policy, the denial letter, the evidence, and the applicable limitation period. Employees should obtain advice before assuming that an internal appeal is mandatory or strategically useful.
