A long COVID disability claim is denied for one reason far more often than any other: the insurer says the tests are normal, so the impairment is not measurable. That answer misreads the policy. A group long term disability contract does not ask whether a scan is abnormal. It asks whether you are able to perform the duties of your occupation, and function is proved by measurement and by records, not by a blood result.
Post COVID condition is not the first illness insurers have treated this way, and the file is built the way chronic pain and fibromyalgia files have been built for years.
The Policy Test Is Function, and No Policy Lists Qualifying Diagnoses
Read the definition of disability in the booklet. It will say something close to being unable, because of illness or injury, to perform the essential duties of your own occupation, and it will change to a stricter test after a set period.
Nothing in that sentence requires a positive test. A diagnosis explains why you cannot work. It is the inability to do the duties that triggers the benefit. The guide chapter on own occupation and any occupation sets out the two tests and why the file has to answer the one in force.
Post COVID Condition Is Recognised, Which Removes One Argument
Post COVID condition is described by the World Health Organization and by the Public Health Agency of Canada, which publishes guidance on post COVID-19 condition and its recognised symptoms, including fatigue, breathlessness and cognitive difficulty lasting months after the infection.
That recognition matters because an insurer cannot credibly say the condition does not exist. It shifts the fight from whether long COVID is real to whether this claimant is impaired by it, which is where the evidence has to be aimed.
Normal Test Results Are the Insurer’s Argument and Not the Legal Test
A denial letter in a long COVID file usually recites that the chest imaging is clear, the bloodwork is unremarkable and the cardiac workup is normal. All of that can be true while the claimant cannot climb a flight of stairs.
Courts have repeatedly accepted disability claims where the impairment was not visible on imaging. The question is credibility and consistency: does the claimant’s reported limitation match what the treating doctors recorded, what the employer observed, and what the claimant actually does day to day.
Function Has to Be Measured, Not Asserted
The strongest long COVID files contain measurements taken over time. A functional capacity evaluation records how long a person can sit, stand, walk and lift, and what happens on the second day of testing. Cardiopulmonary exercise testing records exercise capacity and, in some protocols, the drop on repeat testing that characterises post exertional malaise.
A paced activity diary, kept for weeks rather than days, records what the claimant attempted and what it cost afterwards. Insurers discount a diary written after the denial. They cannot discount one that predates it.
Cognitive Symptoms Need a Different Report
Brain fog is the symptom most often dismissed and the one that most often ends a career. It is documented by neuropsychological testing, which measures processing speed, attention and working memory against normed data and includes validity testing that answers the effort argument before the insurer makes it.
Where the occupation is cognitively demanding, that report is the claim. The guide chapter on LTD medical evidence explains why an attending physician statement, on its own, has never been enough.
The Definition Changes at Two Years and the File Has to Answer the New One
Most group policies pay for an initial period on the own occupation test and then require an inability to perform any occupation for which you are reasonably suited. Claims approved for two years are terminated at that transition every day.
Preparing for it starts long before the letter arrives. A vocational assessment, addressing what work is actually available to a person with variable capacity and unpredictable crash cycles, is what answers the any occupation test. The chapter on the change of definition sets out the timing.
Surveillance Is Used Against a Fluctuating Condition
A condition that varies from day to day is the easiest kind to film selectively. Two hours of footage showing a good hour on a good day is presented as proof of capacity.
The answer is the record that already exists. Where the diary, the treating notes and the functional testing all describe good days followed by collapse, a video of a good hour is consistent with the claim rather than contrary to it. The chapter on LTD surveillance and social media sets out what insurers actually do.
The Internal Appeal Spends the Time You Have to Sue
An insurer that denies a claim invites an internal appeal, which is reviewed by the insurer. Claimants send more of the same evidence, wait, and are denied again, sometimes twice.
The limitation period to sue on the policy runs while that happens. An appeal is worth making only where genuinely new evidence exists and the deadline is being tracked. The chapter on the deadline to sue explains how the period is calculated on a disability policy.
What a Long COVID Disability Claim Looks Like When It Is Ready
A ready file has a treating physician who has recorded limitations instead of symptoms, objective functional testing, neuropsychological testing where cognition is affected, a specialist opinion linking the impairment to the infection, and an employment record showing the attempts to return to work and why they failed.
Assembled in that order, it answers the denial letter point by point. If your claim has been refused, the firm’s long term disability lawyers act against every major Canadian insurer and take these files on contingency.
