Can an Employer Request an Independent Medical Examination (IME) Under WSIA in Ontario?

14 Jun 2026 4 min read No comments Workers’ Compensation (WSIB) Ontario
💡

Under Section 47 of the Ontario Workplace Safety and Insurance Act (WSIA), an employer can request that a worker undergo a health examination. However, they cannot force the worker to attend if the worker formally objects, unless the WSIB reviews the case and officially orders the examination.

When a workplace injury occurs in Ontario, the relationship between the employer and the injured worker can sometimes become strained, especially if the employer doubts the severity of the injury or the recovery timeline. 🏥 Under the Workplace Safety and Insurance Act (WSIA), workers are generally expected to cooperate in their healthcare and return-to-work planning. For businesses in cities like Toronto, Mississauga, or Hamilton, navigating an employee’s medical absence often leads to requests for a third-party medical opinion.

However, an employer does not have unlimited power to demand independent medical examinations (IMEs). 👨‍⚖️ Section 47 of the WSIA provides a very specific legal framework that balances the employer’s need for accurate functional information with the worker’s right to medical privacy. If you are a worker feeling pressured to see a company doctor, or an employer trying to understand your rights, consulting a local Ontario WSIB law firm is often the safest way to ensure compliance without crossing legal boundaries.

Step-by-Step Process for Employer Medical Requests in Ontario

The process of requesting a health examination under the WSIA must be handled carefully. 📝 Bypassing these steps can lead to complaints of harassment or human rights violations.

Step 1: The Employer’s Written Request

The process begins when the employer officially requests, in writing, that the worker undergo an examination by a health professional selected and paid for by the employer. 📄 The employer must clearly explain why this examination is necessary, usually citing a lack of clear functional abilities information from the worker’s treating physician that is preventing a safe return to work.

Step 2: The Worker’s Right to Object

Once the request is received, the injured worker is not legally obligated to simply agree and attend. ❌ The worker has the right to object to the examination. Typically, a worker has 14 days to notify the employer and the WSIB that they do not consent to seeing the employer’s chosen doctor. At this stage, many workers choose to hire a WSIB lawyer to draft the objection.

Step 3: WSIB Intervention and Decision

If the worker objects, the employer must formally ask the WSIB to intervene. ⚖️ The WSIB will review the claim file, the worker’s current medical reports, and the employer’s reasoning. The WSIB will only order the examination if they determine it is absolutely necessary to clarify the worker’s functional abilities or progress, and if the current medical evidence is deemed insufficient.

Step 4: Complying with a WSIB Order

If the WSIB agrees with the employer and formally orders the examination, the worker must generally comply. 🤖 Refusing to attend an examination ordered directly by the WSIB can result in the immediate reduction or total suspension of the worker’s Loss of Earnings (LOE) benefits.

How Much Does it Cost in Ontario?

Requesting an independent examination is a significant financial commitment for an employer. 💵 The WSIB does not cover the cost of a Section 47 examination.

  • Medical Examination Fees: Depending on the specialist (e.g., orthopaedic surgeon, psychiatrist), an employer can expect to pay between $1,500 and $3,500 CAD for the assessment and a detailed report.
  • Worker Expenses: The employer is legally required to reimburse the worker for any travel expenses and lost wages incurred while attending the appointment.
  • Law Firm Retainers: If an employer hires an occupational health and safety law firm to petition the WSIB for the order, legal fees generally range from $300 to $600 CAD per hour.

How Long Does the Process Take?

Resolving a dispute over a medical examination is rarely a quick process. ⌛ After the employer makes the initial written request, the worker has 14 days to respond or object.

If the issue is escalated to the WSIB for a ruling, the adjudicator will typically take 3 to 6 weeks to review the file, gather submissions from both parties, and issue a formal written decision. If the WSIB orders the exam, scheduling the specialist appointment can take an additional 1 to 3 months depending on the doctor’s availability in Ontario.

Frequently Asked Questions (FAQ)

Can the employer use the IME report to fire me?

No. The purpose of a Section 47 examination is strictly to assess your functional abilities for a return-to-work program. Using medical information to unjustly terminate a worker violates the WSIA and the Ontario Human Rights Code.

Does the employer see my full medical history?

No. Even if you attend an employer-requested examination, the doctor is only permitted to report on your functional limitations and abilities related to the workplace injury. They cannot disclose unrelated past medical history to your employer.

Can I bring someone with me to the examination?

Generally, you are allowed to have a support person or even a union representative present during the non-physical parts of the consultation, though the doctor may request privacy during the actual physical examination.

What happens if the employer’s doctor disagrees with my doctor?

Conflicting medical opinions are common. The WSIB adjudicator will weigh both reports. If the WSIB cannot decide, they may order their own independent assessment (under Section 36) to break the tie. Having a WSIB lawyer to argue your doctor’s credibility is highly recommended.
