Toronto Sick Note Laws for Employers: What They Can and Cannot Ask (2026)

Toronto employers are often confused about when they can legally require a sick note. Here's what Ontario law actually says — and what your rights are as an employee.

Toronto Sick Note Laws: What Employers Can and Cannot Ask in 2026

If you work in Toronto and have been asked for a sick note, you're not alone. With over 3 million workers in the GTA, sick note disputes are one of the most common workplace issues. Here's what Ontario law actually says.

Ontario's ESA Sick Leave Rules (2026)

Under the Employment Standards Act (ESA), Ontario employees are entitled to:

  • 3 unpaid sick days per year (called "personal illness days")

  • Employers cannot require a medical certificate for these 3 days

  • This applies to all employees covered by the ESA, regardless of company size


| Situation | Can Employer Require a Note? |
|---|---|
| First 3 ESA sick days per year | No — prohibited by law |
| Days beyond ESA minimum | Yes, if company policy requires it |
| Extended absence (3+ days) | Yes, reasonable to request |
| Return-to-work after injury | Yes, for safety-sensitive roles |
| WSIB-related absence | Separate WSIB process applies |

What Toronto Employers Get Wrong

Many Toronto employers — from Bay Street firms to retail chains on Queen West — still demand sick notes for every absence. This is illegal for the first 3 ESA days. Common violations include:

  • Requiring a doctor's note for a single sick day

  • Threatening discipline if no note is provided for ESA-protected leave

  • Requiring the note to disclose your specific diagnosis

  • Only accepting notes from your "regular" family doctor


Your Rights as a Toronto Employee

1. You don't need to disclose your diagnosis — a note confirming you were unable to work is sufficient
2. Any licensed physician can write your note — your employer cannot require it from a specific doctor
3. Virtual consultations are fully valid — CPSO-registered physicians can provide documentation via telehealth
4. Your employer must accept a legitimate medical note regardless of the issuing physician

Major Toronto Employers and Their Policies

Toronto's largest employers have varying sick note policies:

  • City of Toronto / TTC: Collective agreements (ATU, CUPE) typically require notes after 3 consecutive days

  • Toronto District School Board: Teachers need notes after 5 consecutive days under their collective agreement

  • Big 5 Banks (Bay Street): Most require notes after 3 days, but cannot override ESA minimums

  • Retail/Hospitality (Eaton Centre, PATH): Often demand notes illegally for single days — know your rights


What If You Don't Have a Family Doctor?

Over 2.2 million Ontarians don't have a family doctor — including hundreds of thousands in Toronto. If your employer requires a note and you can't get a walk-in appointment:

  • Walk-in clinics in Toronto average 2-4 hour waits

  • Many walk-in clinics charge $20-40 for sick notes (not covered by OHIP)

  • Virtual options like MedLetter provide same-day documentation from CPSO-registered physicians
