Can You Get Fired for Calling in Sick in Ontario?

No. Ontario's Employment Standards Act (ESA) explicitly prohibits employers from terminating, threatening, or penalizing employees for taking or planning to take sick leave. This is a strong, legislated protection, not just a guideline.

Ontario's ESA Protection is Explicit

Section 74 of Ontario's ESA states that no employer shall intimidate, dismiss, or penalize an employee because the employee has taken, plans to take, or is eligible to take a leave of absence under the Act. This includes sick leave. The protection is absolute for your 3 ESA-protected sick days.

What 'Penalize' Includes

Ontario's protection goes beyond just firing. Your employer also cannot:

• Reduce your hours because you called in sick
• Demote you for using sick leave
• Give you a negative performance review solely for sick days
• Deny you a promotion because of legitimate absences
• Create a hostile work environment because you took sick leave
• Threaten any of the above

Exceptions and Limitations

While the protection is strong, there are situations where termination may be lawful:

• Excessive absenteeism beyond ESA-protected days (if it constitutes frustration of contract)
• Dishonesty about illness (just cause for termination)
• Failure to provide notice of absence per company policy
• Position elimination unrelated to the absence (must prove)
• Inability to perform essential job duties long-term (duty to accommodate first)

Document Everything

The best protection is a paper trail. Keep copies of sick notes, save text messages about your absence, and document any negative treatment after calling in sick. A MedLetter sick note ($49) creates an official medical record that proves your absence was legitimate.

If You've Been Fired

If you believe you were terminated for using sick leave in Ontario, file a complaint with the Ontario Ministry of Labour within 2 years. You may also have a wrongful dismissal claim or a human rights complaint if the illness relates to a disability.
