Can Your Ontario Employer Fire You for Calling in Sick?
In Ontario, employers generally cannot fire you for taking legitimate sick leave. Learn your protections and how proper documentation safeguards your position.
## Short Answer: Generally No
In Ontario, employers cannot fire you simply for taking legitimate sick leave.
## When Termination for Illness Is Illegal
- Using statutory sick days under the ESA
- Having a disability that requires accommodation
- Taking leave for a legitimate medical condition
- Filing a WSIB claim
## When Termination May Be Legal
- Absent without notification (job abandonment)
- Exhausted all leave and cannot return for an extended period (frustration of contract)
- Dishonest about illness
- Absence creates genuine undue hardship
## How Documentation Protects You
A proper sick note creates a paper trail proving absences were legitimate medical leave — making any termination potentially wrongful.
## What to Do If You're Threatened
Document everything, get a sick note, contact the Ontario Ministry of Labour, and consider consulting an employment lawyer. MedLetter provides within 6 hours sick notes that serve as legal documentation.
