Short-Term Disability in Ontario

Life happens. Whether it’s a sudden injury, a planned surgery, or a struggle with mental health that makes it impossible to work, there are times when you just can’t show up for your job. And when that happens, the first thought that often follows is: How am I going to pay my bills?

It’s a terrifying question, and one I hear all the time as an employment lawyer. The stress of being sick is bad enough without adding financial panic to the mix.

This is where Short-Term Disability (STD) comes in. It’s a safety net designed to give you income when you need it most. But the process can feel confusing and intimidating. So let’s walk through it together, step by step.

What Actually Counts as a "Short-Term Disability"?

Simply put, a short-term disability is a medical condition that prevents you from performing the essential duties of your job for a temporary period.

This isn’t just about breaking a leg or having surgery. It covers a wide range of conditions, both physical and mental. Common examples include:

  • Recovery from a major surgery
  • A serious injury from an accident
  • A complicated pregnancy
  • Mental health conditions like severe depression, anxiety, or burnout
  • A critical illness like cancer that requires treatment

The key difference between Short-Term Disability (STD) and Long-Term Disability (LTD) is the duration. STD is for temporary situations, usually lasting a few weeks to several months. If your condition persists beyond that, you would typically transition to LTD.

Who Qualifies for Short-Term Disability?

This is the most important thing to know: Short-term disability is not a government program that everyone gets. It’s an insurance benefit provided through an employer’s group benefits plan.

So, to qualify, you generally need to:

  1. Be an employee of a company that offers an STD plan.
  2. Have worked long enough to be eligible (some plans have a waiting period of a few months after you start).
  3. Have a medical diagnosis from a doctor who certifies that you are unable to work.

Your doctor’s note and the medical documentation are everything here. Without it, the insurance company won’t approve your claim.

How Much Does It Pay? And Who Pays It?

Your STD benefits are paid by the insurance company, not directly by your employer. The amount you receive is a percentage of your regular income, typically ranging from 60% to 85%.

You won’t get paid the day after you stop working. There is almost always a “waiting period” (also called an elimination period) of one to two weeks before your payments begin. You might need to use your sick days to cover this gap.

How Long Can You Stay on STD?

Most STD plans provide benefits for a maximum of 15 to 26 weeks. Your benefits policy will state the exact duration. If you’re still unable to work when your STD runs out, you would then apply for Long-Term Disability, which is a separate process. 

How Do I Apply? A Simple Step-by-Step

The paperwork can seem daunting, but the process usually follows these steps:

  1. Notify Your Employer: Let your HR department or manager know you need to go on leave.
  2. Get the Forms: They will provide you with the application package from the insurance company.
  3. See Your Doctor: You will need to have your doctor fill out their portion of the forms, detailing your diagnosis, treatment plan, and why you can’t work.
  4. Submit Everything: Send the completed forms to the insurance company by the deadline.

What If My Claim Is Denied?

First, don’t panic. Denials happen, but you have the right to appeal. The most common reasons for denial are:

  • The insurance company says there isn’t enough medical evidence.
  • You missed a deadline for submitting paperwork.
  • Your condition is excluded under a “pre-existing condition” clause.

You can and should appeal the decision. If your appeal is also denied, that is the absolute right time to speak with a lawyer.

Can I Be Fired While on Short-Term Disability?

Let me be very clear on this: No, your employer cannot fire you 

Your job is protected under Ontario’s Human Rights Code, which prohibits discrimination based on disability. Firing someone for taking a legitimate medical leave is illegal. Your employer has a duty to accommodate your disability, which includes holding your job for you while you recover.

What About Mental Health Claims?

Yes, absolutely. Mental health is health. Conditions like burnout, anxiety, and depression are legitimate medical reasons for a disability leave.

I won’t sugarcoat it—insurers sometimes scrutinize mental health claims more closely. This makes it even more important to have clear, consistent support and documentation from your doctor, psychologist, or therapist.

Final Thoughts

Taking a disability leave is about prioritizing your health so you can recover and get back to your life. You shouldn’t have to fight for the benefits you are entitled to. Knowing the rules of the game is your first and best line of defense.

Your health comes first. The rest is just noise.
