How Do I Apply for Short-Term Disability?

When someone needs time away from work to recover from illness or injury, most would agree that the short-term disability claims process should be straightforward, however, it is not always as simple as one would expect. 

Take, for example, the case of a financial planner who was denied short-term disability benefits. As reported by the CBC in 2023, this professional was dealing with burnout and unable to keep up with workplace demands. 

They had their short-term disability claim denied by their workplace insurance provider and were issued an ultimatum by their employer: get back to work or face termination.

Nobody would want to face this kind of situation. The truth is, hard-working people sometimes have their disability insurance claims denied, despite their good-faith efforts to meet their employer’s requirements, as well as those of the insurance company. This guide covers what you need to know to avoid surprises when applying for short-term disability. If you have ever asked “how do I apply for short-term disability?” then this post is for you.

What Qualifies for Short-Term Disability?

Many different situations can qualify for short-term disability insurance coverage. This type of insurance is available if you are dealing with an illness or injury that prevents you from being able to perform your job duties.

You don’t need to be hospitalized or in a cast to qualify for short-term disability (STD). Recovery from surgery? Yes. Severe back pain that limits movement? Yes. Burnout or depression so debilitating that you can’t think clearly, let alone perform at your job? Also yes.

Insurers aren’t so much interested in your condition, whether that might entail recovery from surgery to physical injuries, or increasingly common mental health issues, as they are about how your condition affects your ability to execute the essential activities of your role, and whether or not your condition qualifies under the policy in place. 

Applying for STD Benefits

Provide Medical Evidence

Your medical evidence should clearly identify your condition and how it impacts your day-to-day work responsibilities, including a physician’s statement that describes how your condition prevents you from performing essential job tasks, as well as your treatments. 

Complete Your Application Carefully 

You’ll be asked to complete your own detailed claimant statement describing your condition, your limitations, and why you cannot work. Take all the time needed to complete your application in great detail; oversights can mean that your benefits might be denied. 

Healthcare providers will also need to complete an attending physician’s statement, which provides professional medical details supporting your claim. Then your employer will submit a statement outlining your job duties and current employment status.

Small discrepancies, like conflicting information between your statement and your doctor’s report, or insufficient medical evidence, can cause unnecessary questions from your insurer or even rejection of your claim. 

Respect All Timelines 

Submit your application forms and medical documents promptly. Delays can make the insurer suspicious or skeptical of your condition’s severity. When applicants delay in submitting forms, it becomes much more likely that the process will take longer than it would have had everything been submitted promptly. 

Dealing With Denials

Insurers sometimes reject legitimate claims initially, often because medical evidence wasn’t thorough enough or was misunderstood. At Whitten & Lublin, we can help you challenge wrongful denials and advocate forcefully on your behalf.

Frequently Asked Questions About Short-Term Disability 

How much does short-term disability pay?

Most short-term disability (STD) policies replace between 60% and 100% of your weekly income. Some plans offer full pay at the start, then taper off. If your employer pays the premiums, the benefits are generally taxed. If you pay out of pocket, they are usually tax-free. The exact percentage and duration depend on your specific group disability coverage. 

Does anxiety or depression qualify for short-term disability?

Yes, provided the condition prevents you from doing your job and your physician supports that assessment in writing. Mental health claims are commonly accepted by insurers today, but approval depends on how well your medical evidence is presented. 

A diagnosis alone will not qualify you. Your doctor must describe your symptoms in functional terms, showing how they interfere with your job duties. Clear reporting, consistent treatment history, and detailed documentation all strengthen your claim. If the insurer questions whether your condition is severe enough, they may request additional information or deny the claim entirely.

How long does short-term disability coverage last?

Most short-term disability plans provide coverage for between 15 and 26 weeks, though some offer slightly shorter or longer durations. If your condition persists beyond the end of your STD period, the next step may be to apply for long-term disability benefits. That process can take time, and most long-term plans include a waiting period. 

If you expect your recovery will go past the end of your short-term coverage, it is important to start preparing for the next phase early. Timelines vary by insurer, so review your policy documents carefully.

What happens if my short-term disability claim is denied?

A denial does not always mean your condition does not qualify. Insurers often deny claims based on how the information was submitted, rather than what the condition is. 

Your claim may be missing details, contain inconsistencies, or be misunderstood by the person reviewing it. You can often appeal, but time is limited and the appeal must address the reasons listed in the denial letter directly. 

We help people assess where their application went wrong, gather stronger medical evidence, and challenge unfair decisions through internal appeals or legal action with the support of a disability lawyer. The sooner you act, the more options you may have.

Can I be fired while on short-term disability?

In most cases, no. Medical leave is a protected ground under Ontario employment law. Employers cannot legally terminate your position simply because you are off work due to illness or injury. Some may try to argue that the employment relationship has been frustrated, meaning it can no longer continue, but that argument rarely holds unless you have been absent for a long period with no clear return date. 

If your employer threatens termination while you are on leave, or acts on that threat, you may have a strong legal claim for wrongful dismissal or discrimination.

Can I be accused of job abandonment if I’m still sick but my STD was denied?

If you have ongoing medical support confirming you are unfit for work, then a denied insurance claim does not change that. Employers sometimes confuse an insurer’s decision with a green light to demand your return. But a denied claim is not proof that you are ready to work. If your doctor continues to recommend that you stay off, and you maintain communication with your employer, you are not abandoning your job. 

Claims of job abandonment are serious and can affect your record of employment and future benefits. Legal advice is recommended if your employer starts using that language.

What medical documentation do I need to support my STD claim?

You will need a medical report from your treating doctor that clearly describes your diagnosis, treatment, and how the condition limits your ability to perform your job. In addition, you will submit a personal claimant statement, and your employer may be required to submit a job description and employment confirmation. These documents must all tell a consistent story. Insurers look closely at how the medical limitations line up with your actual duties. If your paperwork contains vague language or mismatches, the claim may be delayed or denied until that is resolved.

Can I receive employment insurance sickness benefits while waiting for short-term disability?

If you have STD coverage through your workplace, you are expected to apply and claim benefits under that plan first. Employment insurance (EI) sickness benefits are available only when no private coverage is in place. However, there are exceptions. If your STD claim is delayed or denied, or if you have to wait before receiving payments, you may qualify for temporary EI sick leave support. It is important to coordinate carefully. Receiving both types of benefit at once can trigger repayment requests or affect your future eligibility. Contacting Service Canada and reviewing your insurer’s rules before applying is strongly recommended.

What happens when short-term disability ends?

If you are still unable to work, the next step is often to apply for long-term disability, as you cannot simply extend short-term disability benefits. This is not an automatic transition. You will need to complete a new application process, and the insurer will assess whether you qualify under a different set of criteria. 

During the first two years of long-term disability, you must show you cannot do your own job. After that, you must prove you cannot perform any job for which you are reasonably suited. Many claims are challenged or cut off at that point. If that happens, you may need legal support to continue receiving benefits.
