Accommodation Letters from Doctors: What Ontario Employers Can Demand

15 Jun 2026 5 min read No comments Workplace Discrimination & Human Rights Ontario
💡

In Ontario, employers have the right to request a doctor’s note to confirm the need for a workplace accommodation. However, they can only demand information regarding functional limitations and prognosis. Demanding a specific medical diagnosis is a direct violation of the Ontario Human Rights Code (OHRC).

When an employee in Ontario falls ill or sustains an injury outside of work, transitioning them back into the workplace requires a delicate legal balance. Whether you operate a tech firm in Waterloo, a hospital in London, or a construction company in Hamilton, you will eventually need to process a medical accommodation request. Managing the paperwork properly is essential to maintaining trust and avoiding severe legal liabilities.

A common pitfall for managers is aggressively demanding to know exactly “what is wrong” with an employee. Ontario privacy laws and human rights legislation strictly protect an individual’s private health information. As an employer, your focus must remain entirely on how the medical condition impacts the employee’s ability to perform their job duties. If you are struggling to parse a vague doctor’s note, hiring a specialized employment lawyer from our directory can guide you safely through the accommodation process. 💼

Step-by-Step Guide to Requesting Medical Documentation

Navigating the medical accommodation process requires clear communication and adherence to provincial privacy standards. By following a structured approach, employers can gather the necessary information to modify a worker’s duties without crossing the line into discrimination.

Step 1: Identify the Need for Accommodation

The process usually begins when an employee verbally requests a change to their duties or schedule due to a health issue. Alternatively, an employer may initiate the process if they notice an employee visibly struggling to perform their essential duties due to a suspected medical condition (this is known as the employer’s “duty to inquire”). Document this initial conversation carefully and respectfully. 📝

Step 2: Provide a Functional Abilities Form (FAF)

Do not simply tell the employee to “get a doctor’s note.” Standard doctor’s notes scribbled on a prescription pad are often vague and unhelpful. Instead, provide the employee with a customized Functional Abilities Form (FAF) or a formal letter to their physician. Ensure this document explicitly states that you are not seeking a diagnosis, but rather an assessment of their physical, cognitive, or emotional restrictions.

Step 3: Review the Doctor’s Response for Limitations

Once the employee returns the medical documentation, review it strictly for functional limitations. For example, the note might state, “The patient cannot lift more than 10 lbs,” or “The patient requires a 15-minute screen break every two hours.” It should also provide a prognosis, indicating whether the restrictions are temporary (e.g., 6 weeks) or permanent. If the note is too vague, you may write back to the doctor seeking clarification on specific work-related tasks. 🤔

Step 4: Maintain Strict Medical Confidentiality

Any medical documentation you collect must be kept fiercely confidential. Do not place doctor’s notes in the standard employee personnel file where a general manager might see them. Keep medical records in a separate, secure file accessible only to HR professionals or senior management directly involved in the accommodation process. Gossip regarding an employee’s health condition can lead to severe harassment claims.

Step 5: Implement the Accommodation Plan

Using the doctor’s outlined limitations, collaborate with the employee to create a modified work plan. This might involve altering shift times, buying ergonomic equipment, or reassigning heavy lifting duties to another staff member. Document the agreed-upon plan in writing, have both parties sign it, and set a specific date to review the employee’s progress. 🚨

What Employers Can vs. Cannot Demand

To keep your company compliant with the Human Rights Tribunal of Ontario (HRTO), it is vital to know the boundaries of medical inquiries. Use this reference table when communicating with physicians.

Information TypeCan the Employer Demand It?Example Scenario
Specific DiagnosisNo. Strictly prohibited under the OHRC.Asking “Does the employee have generalized anxiety disorder?”
Treatment Details / MedicationsNo. Unless it directly affects workplace safety.Asking what dosage of antidepressants the worker is taking.
Functional LimitationsYes. This is required for proper accommodation.Asking if the employee can stand for an 8-hour retail shift.
Prognosis for RecoveryYes. Needed for business planning.Asking if the lifting restriction will last 2 months or is permanent.

Who Pays for the Doctor’s Note in Ontario?

Managing the costs associated with medical documentation can sometimes cause friction between the worker and management.

  • General Medical Notes: If an employer requires a basic sick note for a short absence, the employee usually bears the cost. However, the Employment Standards Act (ESA) limits how often employers can demand these for minor illnesses.
  • Detailed Accommodation Letters: If the employer demands a highly detailed Functional Abilities Form or a multi-page letter from a specialist, the employer is generally expected to reimburse the employee. Specialists often charge between $100 CAD and $250 CAD for these reports.
  • Independent Medical Exams (IME): In very complex cases, an employer may request an IME with a third-party doctor. The employer must pay 100% of this cost, which can range from $1,500 CAD to $3,000+ CAD.

How Long Does the Process Take?

Setting realistic expectations for processing medical paperwork ensures the business can plan accordingly.

  • Obtaining the Note: Due to doctor shortages in Ontario, it is reasonable to give an employee 1 to 3 weeks to secure an appointment and return a detailed FAF.
  • Implementing Accommodation: Once the clear restrictions are received, the employer should implement the accommodation almost immediately (usually within a few days) to avoid discrimination claims.
  • Follow-up Reviews: Temporary accommodations should be reviewed every 4 to 8 weeks to see if the employee’s restrictions have lifted.

Frequently Asked Questions (FAQ)

What should I do if the doctor’s note just says “Off work for medical reasons”?

You are allowed to politely write back to the doctor, noting that the letter is too vague for accommodation purposes. Provide them with the employee’s job description and ask if there are any modified duties the employee could safely perform instead of going completely off work.

Can I call the employee’s doctor directly to ask questions?

No. You cannot contact an employee’s physician directly without obtaining explicit, written consent from the employee first. Even with consent, it is generally safer to communicate via formal letters to maintain a clear paper trail.

Can an employee refuse to provide a doctor’s note?

If an employee requests an accommodation but refuses to provide any medical documentation outlining their functional limitations, the employer generally has the right to deny the accommodation until the proper paperwork is supplied.

Do I have to accommodate someone if their doctor says they cannot do 90% of their job?

An employer must accommodate up to the point of “undue hardship.” If a worker is completely incapable of performing the essential duties of their role, and no alternative jobs exist in the company, you may not be legally required to create a redundant position for them.

What happens if the employee’s restrictions pose a safety risk?

Safety always comes first under the Occupational Health and Safety Act (OHSA). If the doctor’s restrictions indicate the employee cannot work safely (e.g., operating heavy machinery while on sedating medication), you must place them on medical leave until it is safe to return.
