Trying to step away from work because anxiety or depression has become unmanageable can feel like a paperwork problem layered on top of a health problem. It is also common.
The Mental Health Commission of Canada estimates that about 30 per cent of short- and long-term disability claims in Canada are attributed to mental health problems and illnesses.
When you combine that with the fact that an Omnibus Survey conducted by Mental Health Research Canada in early 2025 reported that almost half of respondents (42%) have experienced an increase in their level of anxiety, primarily due to the increasing cost of living and political tensions and unpredictability, it is not surprising that more people are asking how short-term disability (STD) claims for mental health issues work.
The problem is that a short-term disability claim for mental health reasons, such as anxiety or depression, often comes with avoidable friction: employers want timelines, insurers want proof, and you may not have the energy to manage either. The cost of getting it wrong can be delays in disability benefits, pressure to return too soon, or a denial that could be hard to reverse.
Short-Term Disability Insurance Coverage Is About Function, Not Labels
Many Ontario employees have access to short-term disability coverage through a workplace benefits package, and the plan’s definition usually focuses on whether your condition prevents you from performing the essential duties of your job. This is not a moral test and it is not a debate about how hard you are trying. It is an assessment of your medical condition and ability to work.
Insurance coverage eligibility criteria is based on functional impairment: concentration, memory, pace, attendance reliability, social interaction demands, tolerance for stress, and decision-making. Anxiety and depression can also involve physical symptoms, including insomnia, fatigue, panic symptoms, appetite changes, and cognitive fog.
Getting Short-Term Disability Approved For Anxiety And Depression
A short-term disability claim requires a clear, consistent record, including a completed medical form confirming you cannot work, and outlines the functional restrictions you are experiencing and an expected duration or reassessment date.
With up-to-date medical documentation showing you sought care from regulated mental health professionals and are following a treatment plan, you give the insurer proof that your symptoms are being treated and that, right now, they meaningfully limit your ability to perform the essential duties of your job.
Common hurdles & how to address them early
A denial often comes down to an insurer saying one of three things: the evidence is incomplete, the condition is not severe enough to prevent work, or there is no treatment plan showing active management. Here are practical ways to reduce those risks:
- If the insurance company asks for specific information, respond directly and on time.
- Avoid vague language. “Stress” is not a helpful claim description on its own. Describe functional impairment in concrete terms.
- Keep work communications separate from medical details. Your employer is entitled to restrictions and expected duration, not a therapy transcript.
If you are dealing with an insurance provider that keeps moving the goalposts, asks for repetitive documentation, or misreads your file, getting legal advice before you send the next round of paperwork can help you find the best way forward.
Frequently Asked Questions about Short-Term Disability Claims For Anxiety and Depression
What qualifies for short-term disability in Ontario for anxiety and depression?
Short-term disability policies require evidence that symptoms meaningfully interfere with work and that you are under appropriate care. This can include anxiety disorders, major depressive disorder, adjustment disorder, and related mental health conditions where functioning is impaired. The insurer may also look for whether there is a severe illness component (for example, suicidal ideation, severe panic, or profound functional decline), but many legitimate claims do not present that way and can still qualify.
A strong mental health claim answers three questions clearly: what the mental health condition is, how it affects your work functioning, and what is being done to treat it. That means you are not only describing depression symptoms or anxiety symptoms, you are showing how they affect your ability to carry out your job duties.
Can depression and anxiety be classed as a disability?
Yes, particularly where symptoms substantially interfere with daily functioning and work.
For disability insurance claims, the disability definition comes from the policy wording, and the evidence needs to show that your mental illness meaningfully prevents you from doing your job during the period claimed. Some plans also distinguish between mental and physical disability in limitation clauses, which is another reason to understand the contract before assuming how coverage works.
How hard is it to get disability for depression and anxiety?
It depends less on the name of the condition and more on the quality of the evidence and the fit between restrictions and your job.
Many people obtain short term disability benefits when documentation is clear, treatment is active, and the impairment is described in functional terms. Where it becomes difficult is when forms are vague, timelines are inconsistent, or the insurer believes there is insufficient proof that work is not possible. Good documentation, timely responses, and consistent clinical support usually make the process smoother.
What if STD is ending and you are not ready to return?
If symptoms persist, some plans allow you to extend short term disability with updated medical support, while others transition you toward other benefit pathways.
For long-term disability coverage, the evidence threshold can increase. Long-term disability benefits are often managed more tightly and involve more reassessments and more detailed documentation to support ongoing mental health disability impairment.
Returning To Work After Mental Health Leave
A return that is rushed is where new problems can start. If you are ready to try returning, push for a written plan that reflects clinical restrictions and includes a review date. A gradual return can be appropriate, but it must match your job’s real demands, not an idealized version.
It also helps to document what “success” looks like for the recovery period: stable sleep, reduced panic frequency, improved concentration, or medication stability. That makes it easier to explain why you are returning now, or why you are not.
