Mississauga Sick Note Laws: When Your Employer Can Ask for a Doctor's Note (2026)

Mississauga workers — from Square One retail to airport logistics — often face sick note demands. Here's what Ontario law actually allows your employer to ask for.

Mississauga Sick Note Laws: When Can Your Employer Ask for One?

Mississauga is Ontario's third-largest city with over 800,000 residents and a massive workforce spanning Pearson Airport logistics, Square One retail, manufacturing along Dixie Road, and the corporate offices in the Hurontario corridor. Here's what the law says about sick notes.

Ontario ESA Rules Apply in Mississauga

As an Ontario city, Mississauga workers are covered by the Employment Standards Act:

  • 3 unpaid personal illness days per year — no sick note can be required

  • Beyond those 3 days, your employer's policy determines documentation requirements

  • Your employer cannot require you to disclose your specific medical condition


Common Mississauga Employer Policies

| Employer/Sector | Typical Sick Note Policy |
|---|---|
| Pearson Airport (GTAA, airlines, ground handlers) | Note after 2-3 days, return-to-work for safety roles |
| Amazon/warehouse (Dixie & Derry) | Note after 3 days, strict attendance tracking |
| Square One retail | Often illegally demands notes for single days |
| Region of Peel (municipal) | Collective agreement: note after 3 consecutive days |
| Corporate offices (Hurontario) | Varies, typically 3+ days |
| Manufacturing (Lakeshore/QEW corridor) | Safety-sensitive roles may require return-to-work notes |

The Mississauga Doctor Shortage

Peel Region has one of Ontario's worst family doctor shortages:

  • Over 200,000 Mississauga residents lack a family doctor

  • Walk-in clinics along Dundas, Hurontario, and Erin Mills are packed

  • Average wait: 2-3 hours at most walk-in clinics

  • Many clinics charge $20-40 for a sick note (not OHIP-covered)


Your Rights as a Mississauga Worker

1. ESA protection: Your employer cannot discipline you for refusing to provide a note for your first 3 sick days
2. No diagnosis required: A note confirming inability to work is all that's needed
3. Any licensed physician: Your employer cannot require the note from a specific doctor
4. Virtual notes are valid: CPSO-registered physicians can provide documentation via telehealth
