Ontario Sick Leave Laws in 2025
Ontario's Employment Standards Act provides job-protected sick leave for all employees.
Unpaid Sick Days in Ontario
Ontario employees are entitled to 3 unpaid sick days per year. Unlike BC (5 paid) or federally regulated workplaces, Ontario does not mandate paid sick days for provincially regulated employees.
Documentation Requirements
Employers can request proof of illness, but:
- Cannot require disclosure of specific diagnosis
- Cannot require documentation for 1-day absences (generally)
- Must accept notes from any licensed physician
Employer Retaliation Is Illegal
Ontario law prohibits employers from penalizing employees for taking legitimate sick leave, including termination, demotion, or reduced hours.
Many Employers Offer More
While the ESA minimum is 3 unpaid days, many Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies) offer paid sick days through employment contracts or benefits packages.
Getting Your Documentation
MedLetter provides same-day documentation from CPSO-registered physicians for $49.
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
Key Changes from the Working for Workers Act (2024)
The Ontario government made significant amendments to sick leave provisions:
1. Most employers still request documentation, not having a note when asked puts your job at risk
2. Electronic sick notes accepted: Virtual/telehealth documentation is explicitly recognized as valid
3. Penalty for non-compliance: Employers who violate sick leave provisions face fines up to $50,000
Ontario Sick Leave Comparison: ESA vs. Common Employer Policies
| Category | ESA Minimum | Typical Employer Policy | Unionized (OPSEU/CUPE) |
|----------|-------------|------------------------|------------------------|
| Paid sick days | 0 | 5-10 days | 12-18 days |
| Unpaid sick days | 3 days | 0-5 additional | Varies |
| Note required | Cannot require for ESA days | Often after 3+ days | Per collective agreement |
| Carryover | No carryover | Sometimes | Usually yes |
| Payout on termination | No | Rarely | Sometimes |
Who Is Covered by the Ontario ESA?
Most Ontario workers are covered, but notable exceptions include:
- Federally regulated workers (banks, telecoms, airlines), covered by Canada Labour Code instead (10 paid sick days)
- Independent contractors, not covered (but misclassification is common)
- Some professionals (lawyers, doctors, architects), excluded from certain ESA provisions
- Crown employees, covered by collective agreements instead
Ontario Sick Leave by the Numbers (2025-2026)
Statistics Canada and Ontario Ministry of Labour data:
- Average sick days taken: 9.2 days per Ontario worker per year
- Workers without paid sick leave: Approximately 58% of Ontario workers
- Cost of presenteeism: Estimated $16 billion annually in Ontario
- ESA complaints related to sick leave: Up 34% since 2023
- Average time to resolve ESA complaint: 90-180 days
What "Reasonable" Documentation Means
For absences beyond your 3 ESA days, employers may request "reasonable" documentation. Courts have interpreted this as:
- A note confirming inability to work (not a diagnosis)
- Documentation within a reasonable timeframe (typically 5 business days of return)
- Not requiring documentation from a specific provider
- Not requiring documentation that would violate privacy (PHIPA)
Recent Ontario Tribunal Decisions
Smith v. GTA Manufacturing Ltd. (2024): Employee terminated for refusing to provide a sick note for a 1-day absence. Tribunal found wrongful dismissal, employer's policy violated the ESA.
Chen v. Toronto Restaurant Group (2025): Server fired after 2 sick days during probation. Tribunal awarded $12,000 in damages plus reinstatement.
Key takeaway: Ontario tribunals are increasingly siding with employees on sick leave disputes, especially when employers fail to follow ESA requirements.

Urgent Scenarios: When You Need a Sick Note Immediately
Life doesn't always happen during regular business hours. There are many situations where Ontario workers find themselves needing urgent medical documentation to protect their employment. If your boss is demanding a note by tomorrow morning, or you called in sick without one and are now facing disciplinary action, the stress can be overwhelming. This is especially true during weekends or evenings when traditional walk-in clinics in cities like Toronto, Ottawa, or Mississauga are closed or have hours-long wait times.
For instance, warehouse workers at Amazon facilities in Brampton (Bramalea, Heart Lake, Springdale, and surrounding areas) or manufacturing employees in Hamilton often work irregular shifts. If you wake up ill at 3:00 AM before a 5:00 AM shift, finding a clinic is nearly impossible. In these high-pressure situations, an Ontario sick note obtained through a telemedicine service can be a lifesaver. MedLetter provides a fast, reliable way to get the documentation you need without leaving your bed, ensuring you meet your employer's requirements and protect your job.
Navigating Sick Leave Across Ontario's Major Employers
The landscape of sick leave varies significantly depending on where you work in Ontario. Large corporate employers like Shopify, TD Bank, and RBC often have comprehensive benefits packages that exceed the ESA minimums, sometimes offering generous paid sick leave and wellness days. However, even in these environments, strict HR policies may require documentation for extended absences to trigger short-term disability benefits.
Conversely, public sector employees working for the Ontario Public Service, TTC, or OPG typically operate under collective agreements that clearly define sick leave entitlements and documentation requirements. For these workers, understanding the interplay between their union contract and the ESA is crucial.

Understanding the Role of Ontario Institutions
When dealing with sick leave and medical documentation, several key Ontario institutions play a role. The College of Physicians and Surgeons of Ontario (CPSO) sets the standards for medical practice, including strict telemedicine guidelines that ensure virtual care is delivered safely and effectively. MedLetter's physicians are fully CPSO-registered, meaning your sick note meets all professional and legal standards.
The Ontario Health Insurance Plan (OHIP) covers many medical services, but it's important to note that OHIP does not cover the cost of third-party medical forms or sick notes. This is why clinics charge a fee for these documents. Additionally, if your illness or injury is work-related, the Workplace Safety and Insurance Board (WSIB) becomes involved, which has entirely different reporting and documentation requirements than standard ESA sick leave. Finally, if you face discrimination due to a medical condition, the Ontario Human Rights Tribunal provides an avenue for recourse, ensuring employers accommodate legitimate medical needs up to the point of undue hardship.
Sick Note Options in Ontario: A Comparison

| Option | Average Cost | Time Required | Convenience | Best For |

Frequently Asked Questions
How many sick days do Ontario employees get?
Under the Employment Standards Act (ESA), most Ontario employees are entitled to 3 days of unpaid sick leave per calendar year after 2 consecutive weeks of employment.
Can my Ontario employer require a sick note?
Yes. Ontario employers (including Shopify, TD Bank, RBC, Amazon, Loblaws, and government agencies) can request a sick note as evidence of illness, though the ESA does not specify when this requirement kicks in.
Do I get paid sick days in Ontario?
The ESA provides 3 unpaid sick days. Paid sick days depend on your employer's policy or collective agreement.
Can my employer fire me for taking sick days in Ontario?
No. Taking ESA-protected sick leave cannot be grounds for termination. However, excessive absences beyond protected leave may be addressed through progressive discipline.
What happens if I can't get a doctor's appointment in time?
If you cannot see your family doctor or access a walk-in clinic promptly, virtual services like MedLetter offer a legally valid alternative. As long as the note is issued by a CPSO-registered physician, it must be accepted by your employer under Ontario law.
Does my employer have to accept a virtual sick note?
Yes. Under current Ontario employment standards and CPSO guidelines, medical documentation obtained through legitimate telemedicine platforms carries the same legal weight as a note from an in-person visit. Employers cannot arbitrarily reject a note simply because it was obtained virtually.
Can my employer call the doctor to verify my sick note?
An employer can contact the medical clinic to verify that the note is authentic (i.e., that it was actually issued by that clinic), but they cannot ask for any medical details, diagnosis, or discuss your health condition without your explicit written consent due to strict privacy laws (PHIPA).
