How to Win a Long-Term Disability Appeal in Ontario

To win a long-term disability (LTD) appeal in Ontario, you must provide clear medical evidence showing how your condition prevents you from performing your job. Most appeals are unsuccessful unless new and compelling evidence is
provided, as insurers are typically reviewing their own decision internally.
Can You Win an LTD Appeal in Ontario?
Yes—but only in certain situations.
Most long-term disability appeals are unsuccessful unless there is new,
meaningful evidence. Because insurers are usually reassessing their own denial using internal medical consultants, the outcome often does not change without a clear shift in the evidence.
Appeals are most likely to succeed where:
new specialist evidence is obtained
objective testing supports the condition
functional limitations are clarified
errors in the original decision are addressed
How Often Do LTD Appeals Succeed?
Many LTD appeals do not succeed.
In practice, insurers frequently:
rely on internal medical reviews
maintain their original position
request additional information without changing the outcome
We often speak with clients who spend months going back and forth through the appeal process before realizing their claim is not moving forward. It is always a good idea to speak with an Ontario disability lawyer when considering your options.
Should You Appeal or Start a Lawsuit After an LTD Denial?
It depends on the situation.
An appeal may be appropriate where:
there is clear new evidence to provide
the denial is based on a specific issue that can be addressed
However, in many cases:
the insurer has already formed a firm position
further internal review is unlikely to change the outcome
and time continues to pass while the limitation period runs
Starting a lawsuit does not prevent resolution, but it does protect your rights and move the process forward.
What Evidence Is Needed to Win an LTD Appeal?
To win an LTD appeal, you need medical and functional evidence that clearly explains why you cannot perform your job.
This includes:
detailed medical records
clear functional limitations
strong support from treating doctors
consistency across all documentation
A diagnosis alone is not enough.
What It Really Takes to Win an LTD Appeal
Most LTD appeals are not denied because someone isn’t genuinely disabled. They are denied because the evidence does not clearly connect:
the medical condition
to specific functional limitations
that prevent the person from working
Insurers are asking: “Is there reliable evidence this person cannot do their job?”
The Most Important Evidence in an LTD Appeal
1. Medical Evidence That Explains Functional Impact
Medical records must go beyond naming a condition.
They should explain:
how symptoms affect daily functioning
how those limitations impact work capacity
whether the condition is ongoing
2. Functional Limitations
This is the most important part of any LTD appeal.
You must show:
what you cannot do
how often you cannot do it
why that prevents you from performing your job
Examples include:
inability to sit, stand, or concentrate for sustained periods
cognitive fatigue or memory issues
inability to meet productivity or pace requirements
3. Strong Support From Treating Doctors
Medical support must be clear and consistent. Strong reports:
provide a clear opinion on disability
explain the reasoning
remain consistent over time
In some cases, specialist involvement is necessary to strengthen the claim.
4. Consistency Across the File
Insurers frequently rely on inconsistencies.
This can include:
differences between medical records
gaps in treatment
discrepancies between reported symptoms and activity
Even minor inconsistencies can be used to justify a denial.
5. Real-World Evidence of Impairment
Additional supporting evidence can help, particularly in more subjective cases. This may include:
failed return-to-work attempts
statements from coworkers or supervisors
documentation of declining performance
We often see clients who expect to recover within a few weeks or months, only to realize later that they are not improving. That history can support the claim if it is properly documented.
How Do Insurance Companies Assess LTD Appeals?
Most major insurers—such as Manulife, Sun Life Financial, and Canada Life—follow similar approaches.
They usually:
review your medical records
obtain internal medical opinions
compare your limitations to your job requirements
look for inconsistencies or gaps
They are not just assessing whether you have a condition. They are assessing whether there is enough evidence to support disability under the policy.
Do You Need New Evidence for an LTD Appeal?
In most cases, yes.
An appeal that simply repeats the same information is unlikely to succeed. Successful appeals typically involve:
updated medical reports
new specialist opinions
more detailed functional assessments
direct responses to the insurer’s concerns
What Are the Risks of Appealing an LTD Denial?
The biggest risk is losing time.
Appeals can take months, and during that time:
the limitation period to start a lawsuit continues to run
the insurer may continue requesting information
the claim may remain denied
In some cases, multiple appeals are completed with no change in outcome.
How Long Do You Have to Appeal an LTD Denial?
Deadlines vary depending on the policy, but they are often short.
It is important to review your denial letter carefully and understand:
your appeal deadline
your limitation period for starting a lawsuit

Final Thoughts
An LTD appeal can be a useful step in some cases—but it is not always the solution.
The key is understanding:
whether the appeal will realistically change the outcome
whether new evidence can be obtained
and whether time is being lost
FAQ

Yes. In many cases, starting a lawsuit is a more effective way to move the claim forward, especially where the insurer has already taken a firm position.

Yes. Appeals are unlikely to succeed unless there is new or stronger evidence addressing the insurer’s reasons for denial.
How long do LTD appeals take in Ontario?
LTD appeals can take several months or longer, depending on the insurer and the complexity of the claim.
What happens if your LTD appeal is denied again?
If an appeal is denied, the next step is typically to start a lawsuit to pursue the claim through the courts.
