What Should a Sick Note Say in Ontario?
A valid Ontario sick note should include: the physician's name and CPSO registration number, date of assessment, recommended absence period, confirmation of medical assessment, and signature. Your diagnosis is private and should NOT be included unless you consent.
Required Elements of an Ontario Sick Note
A legitimate sick note in Ontario must contain:
- Physician's full name and credentials
- CPSO registration number
- Clinic name and contact information
- Date of medical assessment
- Patient's full name
- Confirmation that a medical assessment occurred
- Recommended period of absence
- Physician's signature (electronic signatures valid)
- Official clinic letterhead or format
What Should NOT Be on Your Sick Note
Ontario's PHIPA and Human Rights Code protect the following from disclosure:
- Your specific diagnosis
- Nature of your illness or condition
- Treatment details or medications
- Test results or referrals
- Medical history
- Prognosis
- Whether the condition is physical or mental
Ontario's ESA and Sick Note Content
The Ontario ESA refers to a 'certificate of a qualified health practitioner' but does not specify what it must contain beyond confirming the need for leave. This means your employer cannot demand specific medical details beyond confirmation of illness and duration.
Functional Limitations (Accommodation Context)
If you're requesting workplace accommodation (not just a sick day), your employer may reasonably request information about functional limitations — what you can and cannot do at work. This is different from a diagnosis and should be provided on a separate accommodation form, not a sick note.
