Ontario Sick Note Laws: The 2026 Landscape
Ontario's Employment Standards Act (ESA) governs when employers can require medical documentation. Understanding these rules protects both employees and employers.
The 3-Day Rule
Under the ESA, Ontario employees are entitled to:
- 3 unpaid sick days per calendar year (January 1 - December 31)
- These days are job-protected — you cannot be fired for using them
- Employers cannot require a medical note for these 3 days under the ESA
However, there's a critical nuance: many employers have company policies that go beyond the ESA minimum. If your employment contract or company handbook requires documentation for any absence, that policy may be enforceable.
When Can an Ontario Employer Require a Sick Note?
An employer can legally require a sick note when:
1. You've used your 3 ESA sick days and take additional sick time
2. Your employment contract specifies documentation requirements
3. Company policy (communicated in writing) requires notes for absences
4. The absence exceeds a specified duration (commonly 3+ consecutive days)
5. There's a pattern of absence that raises legitimate concerns
What Can a Sick Note Say in Ontario?
A valid Ontario sick note must include:
- The physician's name and registration number
- Date of assessment
- Statement that the patient was assessed
- Dates of recommended absence
- Any functional limitations (if applicable)
A sick note cannot be required to include:
- Your specific diagnosis
- Details of your medical condition
- Treatment plans or medications
- Prognosis or recovery timeline
Your Rights as an Ontario Employee
Under the Ontario Human Rights Code and ESA:
- You have the right to medical privacy — no diagnosis disclosure required
- You can obtain documentation from any licensed physician (including virtual)
- Your employer cannot contact your doctor without your written consent
- You cannot be penalized for using your ESA sick days
Virtual Sick Notes: Fully Legal in Ontario
The CPSO confirms that virtual care is a legitimate form of medical practice. This means:
- A sick note from a virtual consultation is legally valid
- Employers cannot reject a note because it was issued virtually
- The Ontario Human Rights Tribunal has upheld virtual medical documentation
What If My Employer Rejects My Sick Note?
If your employer rejects a valid sick note:
1. Ask for the rejection reason in writing
2. Review your employment contract and company policy
3. If the note meets legal requirements, the rejection may be unlawful
4. Consider filing a complaint with the Ontario Ministry of Labour
5. Consult an employment lawyer if termination is threatened
