How to Get a Sick Note for Exam Deferral at Ontario Universities

What Your Note Must Include

Ontario Employment Standards: Your Rights

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

• Employers cannot require a doctor's note for ESA-protected sick days as of January 2024 (Working for Workers Act amendments)


• 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 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

Practical Steps for Ontario Employees

1. Know the ESA - Your employer cannot penalize you for taking your 3 statutory sick days
2. Check your employment contract - Many Ontario employers offer 5-10 paid sick days beyond the ESA minimum
3. Unionized workers - OPSEU, CUPE, and Unifor contracts typically provide 12-18 paid sick days annually
4. Document everything - Keep a record of when you called in and who you spoke to
5. Accommodation requests - If you have a chronic condition, consider requesting formal workplace accommodation under the OHRC

When a Sick Note May Not Be Required

While Ontario law has specific rules, most employers still require documentation. Here's when you need to protect yourself:

• Your 3 annual ESA sick days (Working for Workers Act, 2024)


• Family responsibility leave (up to 3 days)


• Bereavement leave (up to 2 days)


• Domestic or sexual violence leave

What Employers Need to Know

Canadian employment law balances employer interests with employee privacy:

• Employers can request confirmation of illness but not specific diagnoses


• The note should state: dates of absence, that the employee was/is unfit for duties, and expected return date


• Employers cannot contact the physician directly without employee consent


• Requiring a note for every single-day absence may constitute harassment in some jurisdictions

Cost Considerations for Employers

• Walk-in clinic notes cost employees $20-50 and require 2-4 hours away from work


• Virtual sick notes reduce time away from work to minutes


• Some employers reimburse sick note costs as a best practice


• The cost of replacing a sick employee for a day far exceeds the cost of documentation
