Can you get fired for calling in sick in Ontario?

A sick woman in Ontario reads the results on a thermometer.

Feeling under the weather and afraid to miss work? You’re not alone. Many people ask: Can you get fired for calling in sick in Ontario? The short answer is no – but it depends on the situation. This guide will help you understand when your job is protected and when you could be at risk.


Can I Get Fired for Calling in Sick?

Under Ontario’s Employment Standards Act (ESA), most employees are entitled to three unpaid, job-protected sick days per calendar year. You qualify once you’ve worked for your employer for at least two consecutive weeks.

If you’re using these protected sick days for genuine medical reasons, your employer can’t legally fire you for that.

So, no, you can’t be fired because you are legitimately sick and can’t work.

Can You Be Fired for Being Sick?

No, you can’t be fired simply for being sick. If the reason for your termination is related to your health, illness, or a medical condition, that is considered a human rights violation in Ontario.

Employers have a duty to accommodate medical conditions up to the point of undue hardship under the Ontario Human Rights Code (OHRC). Terminating an employee due to illness or disability can lead to serious legal consequences.

If you’re fired because of your health:

  • You are likely entitled to full severance pay — up to 24 months’ compensation, depending on your age, position, and length of service
  • You may also be owed human rights damages on top of your severance package

Your employer may try to fire you “for cause” – without severance pay or EI – after calling in sick. It is extremely difficult for a company to justify this type of termination, which means you are very likely entitled to proper severance.

⚠️ If this happens to you, contact an employment lawyer at our firm immediately. Termination based on a medical condition is not just unfair – it’s illegal.

What If I Call in Sick Multiple Days in a Row?

Many employees worry: Can I get fired for taking too many sick days?

No – especially if you’re within your ESA sick day entitlement or can provide reasonable medical proof. Employers can’t punish you for legitimate use of sick leave, even on back-to-back days.

Employers must assess each case individually. You can’t be fired just for taking “too many sick days” if those absences are supported and medically necessary.


How Many Times Can You Call in Sick Before Getting Fired in Ontario?

There’s no legal limit on how many times you can call in sick. However:

If your illness or medical condition persists, you may be eligible for short-term or long-term disabilty benefits through your employer’s group plan or an individual plan you have purchased on your own. If you claims for either one are denied, our Ontario disability lawyers can help you get compensation from the insurance company.

Can You Get in Trouble for Calling in Sick?

No, you can’t get in trouble or penalized for using your sick leave responsibly. Employers are not allowed to:

  • Fire you for taking protected sick leave
  • Discipline or demote you for calling in sick

If your employer does any of the above, it could lead to a wrongful dismissal or human rights claim.

📌 Note: As of October 28, 2024, employers in Ontario can’t require a doctor’s note for the first three ESA-protected sick days. Learn more in our Doctor’s Note Guide.
