Getting a Sick Note for Migraines in Ontario: What You Need to Know

Getting a Sick Note for Migraines in Ontario

Migraines affect approximately 1 in 7 Canadians, and they're one of the leading causes of workplace absenteeism. If you suffer from migraines in Ontario, here's what you need to know about documentation.

Are Migraines a Valid Reason for a Sick Note?

Absolutely. Migraines are a recognized neurological condition. They can cause:

• Severe, debilitating pain


• Nausea and vomiting


• Sensitivity to light and sound


• Inability to concentrate or function

When to Get Documentation

Consider getting a sick note for migraines when:

• Your employer requires documentation for absences


• You've missed 3+ consecutive days


• You have a pattern of migraine-related absences and want to establish a medical record


• You need workplace accommodations (reduced screen time, lighting changes, flexible scheduling)

Chronic Migraines and Workplace Accommodation

If you experience chronic migraines (15+ days per month), you may be entitled to workplace accommodations under the Ontario Human Rights Code:

• Modified lighting at your workstation


• Flexible start/end times


• Work-from-home options during episodes


• Reduced screen time or regular breaks

How MedLetter Helps

When a migraine strikes, the last thing you want to do is sit in a bright, noisy walk-in clinic. MedLetter lets you get a sick note from home in same day — no clinic visit required.

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
