People are often unsure what they are actually entitled to when they are sick, and whether calling in can put their job at risk. In Ontario, there is a baseline of protection, even if it is more modest than many expect, and your job is protected when you are genuinely ill.
✅Quick answer. Under the ESA, most Ontario employees are entitled to three unpaid, job-protected sick days per year after two weeks on the job. There is no statutory right to paid sick days, though your employer may provide them. Your employer generally cannot demand a doctor's note for these ESA days, and you cannot be dismissed for legitimately being sick.
How many sick days do you get in Ontario?
The ESA provides three days of unpaid sick leave per calendar year, available to most employees once they have been employed for at least two consecutive weeks. These days are job-protected, meaning you cannot be penalized for taking them. Your employer or your contract may offer more, but three is the statutory floor.
Are sick days paid in Ontario?
The ESA sick days are unpaid. Ontario does not currently mandate paid sick days. Many employers do provide some paid sick time as a benefit, and a longer illness may be covered by short-term disability or employment insurance sickness benefits, but the statutory entitlement itself is unpaid.
Can your employer require a doctor's note?
Generally not for the ESA sick days. Employers cannot require a certificate from a doctor or other qualified health practitioner as a condition of taking the three statutory sick days. They may ask for evidence that is reasonable in the circumstances in some situations, but the days are meant to be accessible without forcing you to a clinic.
Can you be fired for being sick?
Not for genuinely using your sick leave. And if your illness is ongoing or amounts to a disability, you are protected further: your employer has a duty to accommodate you to the point of undue hardship, the same as with any medical leave. Being dismissed because of illness or disability can be discrimination, which can entitle you to more than ordinary severance.
What about a longer illness?
Three days does not stretch far for a serious condition. A longer absence usually moves into the territory of medical or stress leave, short-term disability or long-term disability benefits, and accommodation. The job protection and the pay are separate questions, and it is worth knowing both before you need them.
