Leave of Absence in Ontario: Explained (Updated for 2025)
An employee takes medical leave for surgery. Weeks later, they’re told their role has been “restructured.”
Another worker requests emergency leave to care for a parent, and is warned that it could affect their future at the company.
These situations are not uncommon. But in Ontario, mishandling a leave of absence Ontario can trigger wrongful dismissal claims, Employment Standards Act complaints, or even human rights liability.
Statutory leaves in Ontario are governed primarily by the Employment Standards Act (ESA). However, medical and disability-related absences may also engage the Ontario Human Rights Code, which can extend protections beyond ESA minimums.
Whether you are an employee requesting time off or an employer managing operational risk, understanding your rights and obligations in 2025 is essential.
When Is a Leave of Absence Legally Protected in Ontario?
Not every absence qualifies as a legally protected leave of absence in Ontario. The key issue is whether the leave falls under the ESA or triggers protections under the Ontario Human Rights Code.
Common ESA-protected leaves include:
- Sick leave (medical leave in Ontario)
- Family responsibility leave
- Bereavement leave
- Pregnancy leave
- Parental leave
- Critical illness leave
- Declared emergency leave
If the leave qualifies under the ESA, employers generally must:
- Allow the employee to take the leave (if eligibility requirements are met)
- Continue benefits (in most cases, unless the employee opts out)
- Reinstate the employee to the same or a comparable position
Improperly denying a protected leave may constitute a reprisal under the ESA. Terminating an employee because they requested or took a leave can expose employers to significant damages. Courts may award damages well beyond ESA minimums if a termination is connected to a protected leave.
For medical leave Ontario cases involving disability, the Ontario Human Rights Code may require accommodation beyond ESA timelines, up to the point of undue hardship. Failing to accommodate properly can result in human rights claims and additional financial exposure.
Employees should not rely on informal verbal approval. Employers should ensure workplace policies align with statutory minimums and do not contract out of ESA protections.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Whether you’re an employee requesting time off or an employer responding to a leave request, it’s essential to understand your legal rights and obligations. At Achkar Law, we help ensure leave decisions are fair, compliant, and backed by sound legal advice.”
Is a Leave of Absence Paid, Or Are You at Financial Risk?
One of the most misunderstood aspects of a leave of absence in Ontario is whether it is paid.
Under the ESA, most statutory leaves are unpaid, including:
- Sick leave
- Family responsibility leave
- Emergency leave
- Bereavement leave
However, compensation may still be available through:
- Employer-provided paid personal leave policies
- Employment contract terms
- Short-term disability benefits
- Employment Insurance (EI) sickness benefits
Medical leave is not automatically paid in Ontario. But employees may qualify for EI sickness benefits or disability coverage through workplace benefit plans.
Employers must clearly distinguish between:
- ESA unpaid leave
- Paid contractual leave
- Disability benefits
- Workplace Safety and Insurance Board (WSIB) claims
Misclassifying leave, deducting pay improperly, or assuming a leave is unpaid without reviewing contractual obligations can create payroll liability, constructive dismissal exposure, and litigation risk.
Before assuming pay will continue during a leave of absence in Ontario, both employees and employers should review employment agreements and benefit plans carefully.
Job Protection: When Must Employers Reinstate You?
Job protection is often the most critical concern in a leave of absence Ontario.
If a leave is ESA-protected, the employer must reinstate the employee to:
- The same position they held before the leave, or
- A comparable position with similar pay, benefits, and status
Reinstatement rights are not absolute job guarantees. An employer may terminate employment during a leave if the decision is entirely unrelated to the leave (for example, a legitimate business closure or restructuring). However, the timing creates legal risk, and employers must be able to prove the decision was unrelated. Failure to do so can result in wrongful dismissal damages and ESA penalties.
For employees returning to work after medical leave in Ontario, employers may:
- Request reasonable medical documentation
- Implement gradual return-to-work plans
- Modify duties as part of the accommodation
Where disability is involved, the duty to accommodate under the Ontario Human Rights Code may extend beyond ESA minimum leave periods. Employers must accommodate to the point of undue hardship.
Employees should document communications and medical recommendations carefully. Employers should document business decisions and accommodation efforts thoroughly to reduce litigation risk.

The duration depends on the type of leave. Pregnancy leave may last up to 17 weeks, parental leave up to 63 weeks, and employees are generally entitled to 3 unpaid sick days annually under the ESA. Other leaves, such as critical illness leave, may extend significantly longer depending on circumstances.
Medical leave Ontario may be taken for illness, injury, surgery, chronic conditions, or mental health concerns. Employers may request reasonable medical documentation but cannot demand excessive or intrusive medical details.
If the leave qualifies under the ESA, the employer must reinstate the employee at the end of the protected leave. If disability is involved, the Ontario Human Rights Code may require accommodation beyond ESA timelines.
Paid leave of absence in Ontario may be available through:
- Employer-provided paid personal days
- Contractual entitlements
- Short-term disability plans
- EI sickness benefits
Payment is not automatic under the ESA.
An unpaid leave of absence Ontario is time off that is legally protected under the ESA but not compensated by the employer. Most statutory leaves fall into this category unless employer policies provide additional paid benefits.
“Personal leave Ontario” is often used informally. Under the ESA, it may refer to sick leave, family responsibility leave, or emergency leave, depending on the situation and eligibility criteria.
Employers must reinstate employees to the same or comparable role if the leave is protected. If medical limitations remain, employers may need to accommodate through modified duties, adjusted schedules, or gradual return-to-work plans.
Emergency leave is generally unpaid under the ESA unless employer policy provides paid days or temporary legislation mandates payment. Employees may explore EI benefits where eligible.
If the leave qualifies under the ESA, an employer cannot deny it. If the time off is discretionary and outside statutory categories, an employer may refuse based on operational needs.
Yes. If the situation qualifies under sick leave or emergency leave under Ontario provisions, employees may leave work. Notice should be provided as soon as reasonably possible in the circumstances.
Medical leave is generally unpaid under the ESA. However, employees may qualify for EI sickness benefits or short-term disability coverage through workplace benefit plans. Even if unpaid, employers must reinstate the employee if the leave qualifies under the ESA or the Ontario Human Rights Code.
Under the ESA, employees are generally entitled to:
- 3 unpaid sick days
- 3 unpaid family responsibility leave days
- 2 unpaid bereavement days
Employers may provide additional paid personal days through workplace policies or employment contracts.
Conclusion: Protect Your Job and Reduce Legal Risk
A leave of absence in Ontario affects more than time away from work. It can determine:
- Whether a termination is lawful
- Whether damages may be owed
- Whether human rights accommodation obligations are triggered
- Whether an ESA complaint or reprisal claim may arise
Employees should confirm their eligibility, pay entitlements, and documentation requirements before requesting or extending a leave of absence Ontario. Employers should proactively review policies and decisions to ensure compliance with both the ESA and the Ontario Human Rights Code.
