Do I Need a Sick Note in Ontario? Your Complete Guide (2026)
Ontario's sick note laws changed significantly with the Working for Workers Act. Here's what employees need to know about their rights and when a sick note is actually required.
## Ontario Sick Note Laws: What Changed in 2024
Ontario's **Working for Workers Act** fundamentally changed sick note requirements in the province. Under the updated Employment Standards Act (ESA), employers are now **prohibited from requiring a medical note** for employees using their 3 paid sick days.
### The Current Legal Framework
Under Ontario's ESA, employees are entitled to:
- **3 paid sick days** per year (no medical note can be required)
- **Additional unpaid sick days** depending on employer policy
- **Job-protected leave** for serious illness (up to 3 days without a note)
### When Your Employer CAN Request a Sick Note
Despite the new protections, employers can still request medical documentation in certain situations:
1. **Absences beyond 3 days** — For extended absences, employers may request verification
2. **Pattern absences** — Frequent absences on specific days may trigger a request
3. **Return-to-work clearance** — After significant illness or injury
4. **Workplace accommodation requests** — When requesting modified duties under the Ontario Human Rights Code
5. **Short-term disability claims** — Insurance providers typically require documentation
### When You Do NOT Need a Sick Note
- Using your 3 ESA-protected sick days
- Absences of 1-2 days where no workplace policy requires it
- Personal emergency leave (first 2 days)
- Bereavement leave
### How to Get a Sick Note in Ontario
If you do need a sick note, you have several options:
1. **Online physician service** — Get a note from a CPSO-registered physician in within 6 hours without leaving home
2. **Walk-in clinic** — Wait times of 2-4 hours, often $20-50 fee
3. **Family doctor** — May take days to get an appointment
4. **Telehealth Ontario** — Free advice line, but they don't issue sick notes
### What Makes a Valid Sick Note in Ontario?
A valid sick note in Ontario must:
- Be issued by a regulated health professional (physician, NP, or other qualified practitioner)
- State the dates of absence
- Confirm the employee was unable to work
- NOT need to disclose the specific diagnosis (privacy protection under PHIPA)
### Your Rights Under the Ontario Human Rights Code
The Ontario Human Rights Code provides additional protections:
- Employers cannot ask for your specific diagnosis
