Can I Be Fired for Absenteeism in Ontario?
Whether missing work is grounds for dismissal depends on why. Innocent, illness-related absence is treated very differently from unexcused no-shows, and firing the wrong way can be costly for employers.
Key takeaways
- The law splits absence into innocent (illness) and culpable (unexcused).
- Innocent absence is usually not just cause and engages accommodation.
- Firing over illness or disability absence can be discrimination.
- Culpable absence can be cause only after progressive discipline.
- Most absence firings are still without cause, meaning severance is owed.

Missing work can put your job at risk, but not all absence is treated the same. Ontario law draws a sharp line between being absent because you are sick and being absent because you did not show up without a good reason. Which side you are on decides whether your employer can dismiss you, and whether they owe you severance. Here is how it works.
✅Quick answer. It depends on the type of absence. Innocent absenteeism, missing work because of genuine illness or disability, is usually not just cause for dismissal, and firing someone over it can trigger the duty to accommodate and human rights protections. Culpable absenteeism, unexcused absences or no-shows, can eventually justify cause, but generally only after clear warnings and progressive discipline. Either way, most absence-related firings are treated as without cause, which means you are owed termination pay, severance, and common-law notice.
Innocent versus culpable absence
- Innocent absenteeism: absence you cannot help, mainly illness, injury, or disability. It is not misconduct, so it is generally not just cause. It also engages your employer's duty to accommodate up to undue hardship.
- Culpable absenteeism: absence within your control that you have no valid excuse for, like unexcused no-shows or repeatedly ignoring call-in rules. This is treated as misconduct and can, in serious and repeated cases, support cause.
Being fired for illness-related absence
If you are absent because you are genuinely sick or disabled, dismissing you for it is fraught for the employer. It usually is not just cause, and it can be discrimination based on disability under the Human Rights Code, plus it may breach the duty to accommodate. There is a narrow doctrine of frustration of contract for permanent, indefinite incapacity, but that is a high bar and does not cover ordinary sick time or a defined medical leave. Being pushed out while dealing with illness is exactly the scenario worth challenging.
Being fired for unexcused absences
Culpable absence can justify cause, but not on a hair trigger. Employers are generally expected to use progressive discipline: warnings that make clear the conduct is unacceptable and that continued absence risks dismissal, with a genuine chance to correct it. A single missed shift rarely justifies firing for cause. Even where some discipline is warranted, jumping straight to a cause termination without that build-up usually fails, which means the dismissal is without cause and severance is owed.
What should you do if you are fired over absence?
- 1.Identify whether your absences were illness or disability related, or unexcused.
- 2.For medical absence, gather documentation and note any accommodation you requested.
- 3.For alleged culpable absence, note whether you got clear warnings and a chance to improve.
- 4.Treat a cause allegation skeptically and get your severance reviewed, since most absence firings are really without cause.
Absence firings often get mislabelled as just cause when they are not. See just cause versus without cause, the duty to accommodate, and stress leave, and if you were let go over absence, a severance review will tell you whether the cause claim holds up.
Frequently asked questions
Can I be fired for being absent due to illness in Ontario?
Usually not for just cause. Innocent, illness-related absence is not misconduct, so it generally does not justify a cause dismissal, and firing over it can be disability discrimination and a breach of the duty to accommodate.
Can unexcused absences be just cause?
They can, but generally only after progressive discipline: clear warnings and a real chance to correct the behaviour. A single missed shift rarely justifies a cause termination, and skipping the warnings usually makes it a without-cause dismissal.
Do I get severance if I was fired for absenteeism?
Often yes. Most absence-related firings are treated as without cause, which entitles you to termination pay, severance, and common-law notice. Cause for absenteeism is a high bar that employers frequently fail to meet.
What if I was on a medical leave when I was fired?
That is a serious red flag. Dismissing someone during or because of a legitimate medical leave can be discrimination and a breach of job-protected leave rights. It is worth getting reviewed right away.
