Sick Notes for Morning Sickness & Pregnancy in Ontario

Morning sickness affects up to 80% of pregnant people, and for some, it's severe enough to require time off work. In Ontario, pregnancy-related illness is strongly protected by law.

Your Legal Protections

Under the Ontario Human Rights Code, pregnancy is a protected ground. This means:

  • Your employer cannot penalize you for pregnancy-related absences

  • They must accommodate pregnancy-related limitations

  • Termination due to pregnancy illness is illegal discrimination


Under the Ontario ESA:
  • You're entitled to up to 17 weeks of unpaid pregnancy leave

  • This is in addition to your regular sick day entitlements

  • Leave can start up to 17 weeks before your due date


When Morning Sickness Requires a Sick Note

Mild nausea usually doesn't require documentation, but consider getting a note when:

  • You're missing multiple days per week

  • You have hyperemesis gravidarum (severe, persistent vomiting)

  • Your employer is questioning your absences

  • You need workplace modifications (flexible hours, breaks, WFH)


How MedLetter Helps

When you're dealing with severe nausea, the last thing you want is a clinic waiting room. MedLetter provides same-day documentation from CPSO physicians, from the comfort of your home.

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 (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


Practical Steps for Ontario Employees

1. Know the ESA - Your your employer faces consequences for penalizing you for taking your 3 statutory sick days
2. Check your employment contract - Many Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies) 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


The Reality of Morning Sickness in Ontario Workplaces

Morning sickness is notoriously unpredictable. It doesn't just happen in the morning; for many, it strikes at 2 PM during a meeting or hits hardest during the evening commute. If you work in a fast-paced environment like Shopify in Ottawa, or a structured corporate setting like TD Bank or RBC in Toronto, managing sudden bouts of nausea can be incredibly stressful.

For those in physical or shift-based roles, such as employees at Amazon warehouses in Brampton (Bramalea, Heart Lake, Springdale, and surrounding areas), drivers for the TTC, or workers at OPG, the physical demands of the job can exacerbate symptoms. In these scenarios, pushing through isn't just uncomfortable; it can be unsafe.

Urgent Scenarios: When You Need a Note NOW

We frequently hear from pregnant Ontarians in high-stress situations:

  • The Boss Demanding a Note by Tomorrow: You called in sick on a Tuesday, and your manager insists on a note before you return on Wednesday.

  • Called in Sick Without One: You woke up violently ill, called your supervisor, and now HR is asking for documentation for your file.

  • Weekend/Evening Crises: It's Sunday night, you've been sick all weekend, and you know you can't face the commute on Monday morning. But all the walk-in clinics in Mississauga (Square One, Port Credit, Streetsville, and Erin Mills) and Hamilton are closed.


In these urgent moments, dragging yourself to a clinic in Kitchener or London is the last thing you should be doing. This is where New sick-note requests are temporarily paused while we review our service. We are not accepting new orders at this time. becomes a lifeline.

Navigating Ontario Institutions

Understanding how different Ontario institutions handle pregnancy-related illness is crucial:

  • CPSO (College of Physicians and Surgeons of Ontario): They set the telemedicine guidelines that allow doctors to assess you virtually and issue valid sick notes.

  • OHIP (Ontario Health Insurance Plan): While OHIP covers your medical care, it does not cover the cost of third-party forms like sick notes. This is why clinics charge a fee.

  • ESA (Employment Standards Act): Specifically, Section 50 outlines your rights regarding pregnancy and parental leave.

  • WSIB (Workplace Safety and Insurance Board): Generally, morning sickness is not a WSIB issue unless it's directly caused by a workplace hazard, but it's important to know the distinction.

  • Ontario Human Rights Tribunal: If you face discrimination or are fired because of severe morning sickness, this is the body that handles those complaints.

| Option | Cost | Timeline | Convenience | Best For |
| :--- | :--- | :--- | :--- | :--- |
| Family Doctor | $20 - $40 (Not OHIP covered) | 1-3 weeks for an appointment | Low (Requires travel and waiting) | Routine checkups, ongoing prenatal care |

Frequently Asked Questions

Can I get a sick note online in Ontario?
Yes. CPSO-licensed physicians can assess patients through virtual consultations and issue legally valid sick notes accepted by Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies).

How much does an online sick note cost in Ontario?
MedLetter charges a flat $49 for a sick note with same-day delivery. This includes the physician assessment and official documentation.

Will my Ontario employer accept an online sick note?
Yes. The College of Physicians and Surgeons of Ontario recognizes virtual care. Online sick notes are legally equivalent to in-person notes.

How long does it take to get a sick note from MedLetter?
Most sick notes are delivered within 2-6 hours of submission. Same-day delivery is standard.

What if my employer in Windsor or Kitchener refuses my online note?
Under Ontario law and CPSO guidelines, an online note from a licensed physician is just as valid as one obtained in person. If an employer refuses it, they may be violating the Ontario Human Rights Code regarding accommodation.

Can a sick note cover me retroactively if I was too sick to get one yesterday?
Yes, in many cases. A physician can assess your current symptoms and your description of the past few days to issue a note that covers a recent, brief absence, which is especially common with unpredictable morning sickness.

Do I need a note for every single day I miss due to morning sickness?
Usually, no. If you have a chronic issue like hyperemesis gravidarum, a physician can provide a note outlining the need for intermittent absences or specific accommodations (like flexible start times) over a set period, rather than requiring a new note every day.
