As an Ontario employer, managing employee absences requires balancing business needs with employee rights. Here's what you can and can't require.

Employer Rights and Obligations

Navigating the complexities of employee absenteeism in Ontario requires a clear understanding of both employer rights and employee protections. Under the Employment Standards Act (ESA) and the Ontario Human Rights Code, employers must balance their operational needs with the legal rights of their workforce. Whether you are managing a small business in Kitchener or overseeing a large team at a major corporation in Toronto, understanding these rules is essential for maintaining a compliant and productive workplace.

What You CAN Require


As an employer in Ontario, you have the right to manage your workforce effectively and ensure operational continuity. You can require:
  • Proof of illness for absences exceeding 3 days, provided it aligns with your company policy and the ESA.

  • A clear absence reporting policy that outlines exactly how and when employees must notify management of their illness (e.g., calling a supervisor at least two hours before a shift).

  • Return-to-work clearance for extended absences, especially if the employee's role involves safety-sensitive duties, heavy machinery, or physical labor.

  • Accommodation documentation to understand the functional limitations of an employee returning from a medical leave, ensuring you can provide appropriate support and modifications to their duties.


What You CANNOT Require


The legal landscape in Ontario strictly limits what employers can demand from sick employees, protecting workers from unnecessary intrusion. You cannot require:
  • Disclosure of specific medical diagnoses. Employees have a fundamental right to medical privacy under the Personal Health Information Protection Act (PHIPA).

  • Sick notes for every single-day absence. The Ontario government strongly discourages this practice as it places an undue burden on an already strained healthcare system.

  • Refusal of notes from online medical services. The College of Physicians and Surgeons of Ontario (CPSO) explicitly recognizes telemedicine, making online notes legally valid and equivalent to in-person assessments.

  • Penalizing employees for using their statutory sick leave entitlements.

  • Requiring an employee to see a specific doctor or a company-appointed physician for a standard sick note.


Privacy (PHIPA) and Medical Documentation


When handling medical documentation, Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies) must adhere to strict privacy standards. You should only collect necessary health information that pertains directly to the employee's ability to perform their job. Sick notes should confirm the employee's inability to work without revealing the underlying diagnosis. Furthermore, you must store all medical information securely and entirely separately from regular personnel files. You cannot share this sensitive information with other staff members, including direct supervisors, beyond what is strictly necessary for implementing workplace accommodations.

Best Practices for Ontario Employers


To maintain a healthy and legally compliant workplace, employers should establish clear, written policies regarding sick leave and medical documentation. These policies must be applied consistently across all departments to avoid claims of discrimination. Acceptance of notes from any licensed physician, including those obtained through virtual care platforms, is essential. When discussing return-to-work plans, always focus on the employee's functional limitations rather than their specific medical conditions or diagnoses.

Ontario Employment Standards: Your Rights

Under Ontario's Employment Standards Act, 2000 (ESA), specifically Section 50, employees are entitled to 3 unpaid sick days per calendar year. While some employers offer paid days, the statutory minimum provides crucial job protection for vulnerable workers. Important provisions include:

  • Employers cannot require a doctor's note for ESA-protected sick days as of January 2024, following critical amendments introduced by the Working for Workers Act.

  • The Ontario Human Rights Code requires employers to accommodate medical conditions to the point of undue hardship, which may involve modifying duties, providing specialized equipment, or adjusting schedules.

  • Federally regulated employees working in Ontario, such as those at TD Bank, RBC, or in the telecommunications sector, 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 for absences that exceed the statutory minimums, which is distinct from a legal requirement but still enforceable if reasonable.


Statistics: Healthcare Access in Ontario

The reality of obtaining a traditional sick note in Ontario is increasingly difficult, highlighting the need for alternative solutions. According to Ontario Health and Statistics Canada (2025-2026):

  • 2.3 million Ontarians lack a regular family doctor or nurse practitioner, making it nearly impossible to get a quick appointment for a minor illness.

  • The average emergency room wait time in Ontario is over 4 hours for non-urgent cases, a significant burden for someone who simply needs a sick note for work.

  • Walk-in clinic wait times in the Greater Toronto Area (Downtown, North York, Scarborough, Etobicoke, Mississauga, Brampton) (GTA) average 1.5-3 hours, assuming the clinic hasn't already reached capacity for the day.

  • Ontario currently has the lowest physician-to-population ratio of any large province in Canada, exacerbating the primary care shortage across the province.


The Urgency of Sick Notes in Ontario

Employees often find themselves in situations where they urgently need medical documentation to protect their employment. Consider the scenario where a boss is demanding a note by tomorrow morning, or an employee has called in sick without realizing a note was required for their specific absence. These situations are particularly stressful during weekends or evenings when traditional walk-in clinics in cities like Toronto, Ottawa, or Mississauga are closed.

For workers at major employers like Shopify, the Ontario Public Service, the TTC, OPG, or Amazon warehouses, strict attendance policies can make the sudden need for a sick note a high-stress event. When you are too sick to sit in a crowded waiting room in Brampton (Bramalea, Heart Lake, Springdale, and surrounding areas) or Hamilton, but your job depends on providing documentation, the urgency is real. This is where accessible telemedicine services become a critical lifeline, allowing employees to meet their employer's requirements without further compromising their health or spreading illness.

Practical Steps for Ontario Employees

Navigating sick leave in Ontario requires a proactive approach. Here are practical steps for employees to protect themselves:
1. Know the ESA - Your your employer faces consequences for penalizing you for taking your 3 statutory sick days under Section 50 of the Employment Standards Act.
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. Review your benefits package carefully to understand your entitlements.
3. Unionized workers - If you belong to a union like OPSEU, CUPE, or Unifor, your collective agreement typically provides 12-18 paid sick days annually, along with specific, negotiated rules regarding medical documentation.
4. Document everything - Keep a detailed record of when you called in sick, who you spoke to, and any correspondence regarding your absence.
5. Accommodation requests - If you have a chronic condition, consider requesting formal workplace accommodation under the Ontario Human Rights Code. This process may involve the Workplace Safety and Insurance Board (WSIB) or the Ontario Human Rights Tribunal if disputes arise.

When a Sick Note May Not Be Required

Under Ontario law, a sick note is generally not required for specific types of protected leave. These include:

  • Your 3 annual ESA sick days, as reinforced by the Working for Workers Act, 2024.

  • Family responsibility leave, which allows up to 3 days per year to care for ill family members.

  • Bereavement leave, providing up to 2 days following the death of a family member.

  • Domestic or sexual violence leave, which offers protected time off for survivors seeking medical attention or legal assistance.


What Employers Need to Know

Canadian employment law carefully balances employer operational interests with employee privacy rights. Employers can request confirmation of illness to validate an absence, but they cannot demand specific medical diagnoses. A legally sound sick note should state the dates of absence, confirm that the employee was or is unfit for duties, and provide an expected return date.

Crucially, employers cannot contact the physician directly to verify the note or ask for more information without the explicit, written consent of the employee. Furthermore, requiring a note for every single-day absence may constitute harassment in some jurisdictions and is generally viewed as an unreasonable burden on both the employee and the healthcare system.

Cost Considerations for Employers

The financial impact of sick notes extends beyond the employee. Consider the following cost dynamics:

  • Walk-in clinic notes typically cost employees $20-50 out of pocket, as these administrative services are not covered by OHIP, and require 2-4 hours away from work.

  • Virtual sick notes significantly reduce time away from work to mere minutes, allowing employees to rest and recover faster.

  • Some progressive employers reimburse sick note costs as a best practice, recognizing that the requirement is a company policy rather than a medical necessity.

  • Ultimately, the cost of replacing a sick employee for a day, or dealing with the fallout of an employee coming to work sick and infecting others, far exceeds the cost of documentation.

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). The CPSO telemedicine guidelines fully support this practice, ensuring that virtual care meets the same standards as in-person visits.

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. There are no hidden fees or subscription requirements.

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 and must be accepted by employers across the province, from small businesses to large corporations.

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, which is ideal for urgent situations where your employer requires immediate documentation.

What if my employer insists on knowing my diagnosis?
Your employer does not have the right to know your specific medical diagnosis under Ontario privacy laws (PHIPA). They are only entitled to know your functional limitations and expected return-to-work date. If they persist, you may need to consult with HR or the Ontario Human Rights Tribunal.

Can my employer fire me for taking sick days?
If you are using your 3 statutory sick days under the ESA, your employer cannot legally penalize or terminate you. Doing so would be a violation of the Employment Standards Act. However, for extended absences not covered by the ESA or company policy, the situation becomes more complex and may require legal advice.
