• Treatment plans or therapy details

• Appears fraudulent (inconsistent information, no verifiable physician)


• Doesn't come from a licensed physician or nurse practitioner


• Doesn't cover the dates of absence claimed


• Is from a practitioner not authorized to issue sick notes in Ontario

• It was issued virtually/online (CPSO recognizes virtual care)


• It doesn't include a diagnosis (not required by law)


• It's from a physician they don't personally recognize


• It's "too generic" or "too brief" (if all required elements are present)


• It doesn't include a specific return date (for open-ended absences)


• The physician is not the employee's regular doctor

How to Verify a MedLetter Sick Note

Every MedLetter sick note includes a unique Letter ID. Employers can verify authenticity at medletter.ca/verify by entering:

• Letter ID (format: ML-XXXXX-2026)


• Patient initials


• Date of issue

• The note was issued by MedLetter


• The physician is CPSO-registered


• The note has not been altered


• The dates match what was issued

Sample Sick Note Format

A properly formatted Ontario sick note reads similar to:

---

[Physician Name, MD]
CPSO Registration: [Number]
[Practice/Clinic Name]
[Date of Assessment]

To Whom It May Concern,

This letter confirms that [Patient Name] was assessed on [Date] and is unable to attend work/school from [Start Date] to [End Date] due to a medical condition.

The patient is expected to return to regular duties on [Return Date].

[Physician Signature]
Letter ID: ML-XXXXX-2026

What this note does NOT say: It doesn't mention the diagnosis, symptoms, treatment, or any other private medical information. This is intentional and legally correct.

Common Employer Mistakes with Sick Notes

| Employer Action | Legal? | Your Response |
|----------------|--------|---------------|
| Demanding diagnosis | No | "My note confirms I was unable to work. My diagnosis is private." |
| Rejecting virtual note | No | "CPSO recognizes virtual care. This note is legally valid." |
| Requiring specific doctor | No | "I can obtain documentation from any licensed physician." |
| Calling your doctor | No | "You cannot contact my physician without my written consent." |
| Requiring note for ESA days | No | "The Working for Workers Act prohibits this for my 3 ESA sick days." |
| Sharing note with coworkers | No | "Medical documentation must be kept confidential." |

Ontario Employment Standards: Your Rights

Under Ontario's Employment Standards Act, 2000 (ESA), employees are entitled to 3 unpaid sick days per year. Important provisions:

• Employers cannot require a doctor's note for ESA-protected sick days (Working for Workers Act, 2022)


• The Ontario Human Rights Code requires employers to accommodate medical conditions to the point of undue hardship


• Federally regulated employees in Ontario get 10 paid sick days under the Canada Labour Code


• Many Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies) still request notes as a matter of company policy (distinct from legal requirement)

Statistics: Healthcare Access in Ontario

According to Ontario Health and Statistics Canada (2025-2026):

• 2.3 million Ontarians lack a regular family doctor or nurse practitioner


• Average emergency room wait time in Ontario: over 4 hours for non-urgent cases


• Walk-in clinic wait times in the GTA: 1.5-3 hours on average


• Ontario has the lowest physician-to-population ratio of any large province


• 45% of Ontarians report difficulty accessing primary care

Red Flags: When a Sick Note Might Be Fraudulent

For employers' reference, legitimate concerns include:

• No verifiable CPSO registration number


• Physician name does not appear in CPSO public register


• Note appears to be a template with handwritten additions that don't match


• Dates are inconsistent or impossible


• No contact information or verification method


• Note claims to be from a clinic that doesn't exist
