Fired for Calling in Sick in Ontario? What the Law Actually Protects and What to Do Next

Can I be fired for calling in sick in Ontario?

Generally no. Ontario's Employment Standards Act, 2000 provides job-protected sick days and prohibits reprisals against employees who use them. Terminating an employee for taking legitimate sick leave may be wrongful dismissal. Where the illness qualifies as a disability under the Ontario Human Rights Code, termination instead of accommodation may also constitute discrimination.

How many sick days am I entitled to in Ontario?

Under Ontario's ESA, most employees are entitled to at least 3 unpaid sick days per calendar year after two weeks of employment. Your employer may provide more through a workplace policy. These are job-protected days your employer cannot fire or discipline you for using them. Where illness qualifies as a disability, additional accommodation may be required beyond these statutory days.

Can I be fired for being sick too often in Ontario?

Frequent absences can raise employment concerns, but your employer cannot terminate you solely for legitimate illness without first exploring accommodation where a disability is involved. Where absences are excessive and unsupported by medical evidence, or where they genuinely prevent you from performing the essential duties of your role even with accommodation, a termination may be more defensible. The employer must still demonstrate it explored accommodation before acting.

Do I need a doctor's note when I call in sick in Ontario?

Your employer can ask for reasonable evidence of your inability to work, but they cannot demand a specific form such as a doctor's note in all circumstances. For short absences, a self-declaration is generally sufficient. For longer absences or where accommodation is being requested, medical confirmation of the need to be absent and the expected duration may be required. You are not required to disclose your diagnosis only that you were unable to work.

What if my employer says the termination was for a different reason?

Courts look closely at the timing and full circumstances of a termination where it follows sick leave. A termination that occurs shortly after sick leave with no documented pre-existing performance concerns raises a strong inference that the leave was a factor regardless of the stated reason. Evidence of the real motivation including the timing, the absence of prior documentation, and any statements made about the absences is assessed holistically. Get legal advice to assess whether the stated reason holds up.

Can I file a Ministry of Labour complaint if I was fired for sick leave in Ontario?

Yes. A reprisal for exercising your right to ESA sick days can be the subject of a complaint to Ontario's Ministry of Labour. The Ministry can investigate and order remedies. Limitation periods apply so act promptly. A Ministry of Labour complaint and a wrongful dismissal claim can sometimes be pursued in parallel depending on the specific circumstances. A lawyer can help you assess which route or combination of routes is most effective for your situation.
