How Long Can You Be Off Sick Without a Doctor's Note in Ontario?
Ontario banned sick note requirements for ESA-protected days in 2022. But employers can still require notes in certain situations.
## How Long Can You Be Off Sick Without a Doctor's Note in Ontario?
Ontario has some of the clearest rules in Canada about when employers can and cannot require sick notes, thanks to the Working for Workers Act (2022).
### The Legal Framework
**Ontario ESA (3 unpaid sick days):**
- Employers **CANNOT** require a medical note for these days
- This is law since October 2022
- Applies to all Ontario employees with 2+ weeks of service
**Beyond ESA days:**
- Employers CAN require documentation per their workplace policy
- Must be applied consistently to all employees
- Cannot be used to discriminate
### When Your Employer CAN Require a Note
| Situation | Note Required? |
|-----------|---------------|
| Days 1-3 (ESA protected) | **No** (illegal to require) |
| Days 4+ (employer policy) | Potentially yes |
| 3+ consecutive days (common policy) | Usually yes |
| Return from extended absence | Usually yes |
| Pattern absences | Employer may request |
| WSIB claim | Yes (specific forms) |
### Common Ontario Employer Policies
- **Retail/hospitality**: Note after 3 days
- **Healthcare**: Note after 3 days
- **Government/union**: Varies by collective agreement (often 5+ days)
- **Tech**: Often 5+ days or unlimited
- **Manufacturing**: Note after 3 days
### The Practical Answer
For most Ontario employees:
- **Days 1-3**: No note required (law)
- **Days 4-5**: Check your employer's policy
- **5+ days**: Almost certainly need documentation
- **Return from extended leave**: Always need a return to work letter
