Medical Note Costs: Can Ontario Employers Force You to Pay Without Reimbursement?

💡

Under the recent Working for Workers Five Act (Bill 190) passed in late 2024, Ontario employers are strictly prohibited from demanding a medical sick note for your three statutory sick days. However, for longer absences where a medical note can still be legally requested, the employer is NOT required by law to reimburse you for the doctor’s fee, meaning you must pay out of pocket.

Waking up with a severe flu or sudden injury in cities like Toronto, Mississauga, or Hamilton is stressful enough without having to worry about workplace politics. 👨‍⚕️ Historically, a major source of friction between Ontario workers and their employers has been the demand for a medical sick note. Because the Canadian healthcare system does not cover the administrative cost of writing sick notes (also known as third-party medical certificates), doctors and walk-in clinics routinely charge patients a fee ranging from $20 to $50 CAD simply to write a note proving they are ill. For minimum-wage earners, this fee can wipe out a significant portion of a day’s pay.

For years, workers asked a simple question: “If my boss forces me to get a sick note, do they have to pay for it?” The legal answer has recently undergone a massive shift. With the passage of Bill 190 in late 2024, the Ontario government drastically changed how employers can manage short-term absenteeism. While the new laws offer unprecedented protections against unnecessary doctor visits, there are still specific scenarios where an employer can demand a note without opening their wallet. This guide will clarify your rights regarding sick notes, who bears the cost, and how to handle illegal demands from your employer.

The 2024 Bill 190 Revolution: Banning Sick Notes for Short Leaves

The most important update to Ontario employment law in recent years is the prohibition on sick notes for statutory leave. 📚 Under the Employment Standards Act (ESA), most employees have the right to take up to three unpaid days of sick leave per calendar year. Prior to Bill 190, employers could demand a doctor’s note for even a single day off. Today, this practice is completely illegal. An employer cannot require a certificate from a qualified health practitioner to validate these three statutory sick days. They can only ask for “evidence reasonable in the circumstances,” which generally means a simple verbal or written self-attestation from the employee.

Who Pays for the Note When It Is Legally Required?

While the Bill 190 ban protects you for short, three-day absences, the rules change if your illness extends beyond your statutory entitlement. If you are off work for a week, applying for short-term disability, or seeking long-term medical accommodations, your employer is legally permitted to ask for a medical certificate to support the extended absence. In these situations, the ESA does not require the employer to reimburse you for the cost of the note. Unless you have a specific employment contract, a robust company benefits plan, or a union Collective Bargaining Agreement (CBA) that states the employer will cover the fee, the financial burden falls entirely on you.

Step-by-Step Process for Handling Medical Note Requests in Ontario

If your manager texts you demanding a sick note before you return to work, it is important to handle the situation carefully to avoid disciplinary action while protecting your rights. 📋 Here is the step-by-step process you should follow.

Step 1: Determine the Length of Your Absence

First, evaluate if your absence falls under the three statutory sick days provided by the ESA. If you have worked for the employer for at least two consecutive weeks, you are entitled to these three days annually. If you are taking one of these protected days, the Bill 190 protections apply to you immediately.

Step 2: Provide an Attestation Instead

If the employer demands a note for a statutory sick day, politely inform them of the current law. 📧 Send an email stating: “As per the Working for Workers Five Act (Bill 190) amendments to the ESA, employers can no longer require a medical certificate from a health practitioner for statutory sick leave. Please accept this email as my reasonable attestation that I am absent today due to personal illness.”

Step 3: Obtain and Pay for a Note for Long-Term Absences

If your absence stretches beyond your three statutory days, or if you are seeking an official workplace accommodation (like modified duties), you must comply with a request for medical evidence. 🗂 Visit your doctor or a local clinic, pay the requested fee, and ensure the note clearly outlines your functional limitations or expected return date, without disclosing your specific medical diagnosis (which remains private).

Step 4: Check Company Policies for Reimbursement

Even though the law does not mandate it, many progressive companies or unionized workplaces in Ontario have internal policies agreeing to pay for requested sick notes. Check your employee handbook or speak to your union steward. If a policy exists, submit your clinic receipt to HR for reimbursement.

Step 5: Escalate Illegal Deductions or Reprisals

If an employer illegally docks your pay, sends you home without pay, or fires you for refusing to buy a sick note for a one-day statutory absence, you must take action. You can file an Employment Standards Claim online with the Ontario Ministry of Labour. The government will investigate the employer for violating the ESA and can order them to pay lost wages or fine them heavily.

How Much Does it Cost in Ontario?

Dealing with sick note requests involves specific medical and administrative costs. 💲 Here is a breakdown of what you might spend:

  • Walk-in Clinic / Family Doctor Fee: Writing a sick note is an uninsured service under OHIP. Doctors typically charge between $20 and $50 CAD for a basic note.
  • Detailed Functional Abilities Form: If you need a comprehensive medical form filled out for an accommodation or insurance claim, doctors can charge between $50 and $150 CAD.
  • Ministry of Labour Claim: If you are fired or penalized for asserting your Bill 190 rights, filing an ESA reprisal claim against your employer is 100% free.

How Long Does the Process Take?

Obtaining a sick note usually takes an hour or two at a local clinic, depending on wait times. ⏱ If you are fighting an illegal reprisal (for example, you were suspended for two days without pay because you refused to provide a banned sick note), resolving the issue through the Ministry of Labour takes longer. Once a claim is filed, an investigation generally commences within 30 to 90 days. If the investigator finds the employer violated the ESA, they can issue an order for compensation.

When Can Employers Ask for Medical Evidence?

Absence TypeCan They Demand a Doctor’s Note?Who Pays for It?
Statutory Sick Leave (1 to 3 Days)No. Prohibited by Bill 190.N/A (Note cannot be required).
Non-Statutory Absence (4+ Days)Yes. To justify the continued absence.Employee (unless contract says otherwise).
Workplace Accommodation RequestYes. To understand medical limitations.Employee (unless contract says otherwise).
WSIB (Workplace Injury) ClaimYes. Functional Abilities Form required.WSIB covers specific form costs directly.
What is considered “reasonable evidence” if I can’t use a sick note?

Under the ESA, reasonable evidence for a statutory sick day depends on the situation, but the Ontario government has stated it can often simply be a verbal statement, an email, or a written attestation from the employee confirming they were ill.

Can my employer call my doctor to verify a note?

An employer can call the clinic to verify that the note is authentic and was indeed issued by that specific doctor. However, the employer CANNOT ask the doctor about your specific medical diagnosis or treatment plan due to strict privacy laws.

Can I be fired for taking too many sick days in Ontario?

You cannot be fired or disciplined for taking your three protected statutory sick days. However, if you frequently miss work beyond your protected days, an employer can eventually terminate you for “innocent absenteeism,” provided they have fulfilled their duty to accommodate your medical needs up to the point of undue hardship.

Does my employer have to accept a note from a nurse practitioner?

Yes. In Ontario, a “qualified health practitioner” includes doctors, nurse practitioners, and registered psychologists. An employer generally cannot refuse a valid medical certificate issued by an authorized nurse practitioner.

What if my employer deducts the cost of the sick note from my pay?

An employer cannot deduct money from your paycheque to cover administrative costs or penalties without your explicit written authorization. If they do, it is an illegal wage deduction, and you can file a claim with the Ministry of Labour.
