What Is an Independent Medical Examination (IME)?

When conducted by experienced specialists and aligned with the appropriate discipline, the IME process supports transparent, clinically sound decision-making.

A Complete Guide to the IME Process in Canada

Independent Medical Examinations (IMEs) are widely used across Canada to provide objective medical clarification in legal, disability, occupational, and complex health matters.

Yet common questions remain:

• What is an IME?
• What happens during an IME?
• How does the IME process work in Canada?
• Is attendance at an IME required?

This guide outlines the IME process clearly - what it is, what it is not, and what both referrers and examinees can expect.

What Is an Independent Medical Examination?

An Independent Medical Examination (IME) is a structured, objective medical assessment conducted by a qualified physician or specialist (often called an ‘assessor’) who has not previously been involved in the individual’s care.

Its purpose is to provide an impartial medical opinion addressing defined referral questions. These questions may relate to:

• Diagnosis
• Functional capacity
• Work ability
• Causation
• Treatment considerations
• Prognosis

An IME is evaluative - not therapeutic. The assessor does not provide ongoing care.

What an IME Is - and What It Is Not

An IME is:

• An independent, third-party medical evaluation
• A review of relevant medical records
• A clinical examination aligned with specific referral questions
• An evidence-based medical opinion

An IME is not:

• A treatment appointment
• A replacement for a primary care provider
• A therapy session
• An advocacy assessment

The assessor’s role is to provide neutral, clinically grounded analysis.

Who Requests an IME?

IMEs are typically requested by organizations or professionals seeking independent medical clarification. This may include:

• Insurers
• Employers
• Disability management professionals
• Legal representatives
• Regulatory or adjudicative bodies

The referral defines the scope of the examination and the questions the physician is asked to address.

What Happens Before the IME?

Before the appointment, the assessor reviews all relevant documentation, which may include:

• Medical records
• Specialist reports
• Diagnostic imaging
• Treatment history
• Occupational information

A thorough record review ensures the assessment is informed, focused, and clinically appropriate.

The examinee receives confirmation of the appointment details, including the specialty of the assessor and any necessary instructions.

What Happens During the IME?

The structure of the examination depends on the medical discipline involved - such as psychiatry, neurology, orthopaedics, physiatry, or rheumatology.

Most IMEs include:

1. A detailed medical history
2. Review of current symptoms
3. Physical or psychological examination
4. Functional assessment, where relevant
5. Discussion of occupational or daily activity demands

The evaluation is structured and objective. Its purpose is to assess clinical findings and determine how medical conditions affect function.

Appointment length varies based on complexity and specialty.

What Happens After the IME?

Following the assessment, the physician prepares a comprehensive written report that includes:

• Summary of documentation reviewed
• Clinical findings
• Diagnostic impressions
• Responses to referral questions
• Opinion regarding impairment, functional impact, and prognosis

The report is provided to the referral source to support informed decision-making.

Treating Physician vs. Independent Assessor

Understanding the distinction between roles is important.

Treating Physician

• Provides ongoing care
• Focuses on treatment and recovery
• Maintains a therapeutic relationship

Independent Medical Assessor

• Conducts a time-limited evaluation
• Maintains neutrality
• Provides objective medical analysis
• Addresses defined referral questions

Both roles are essential - but they serve different purposes.

Why Specialty Matching Matters

The quality of an IME depends on selecting the appropriate medical discipline.

Complex cases may require expertise in:

• Psychiatry
• Psychology
• Neuropsychology
• Neurology
• Orthopaedic Surgery
• Physiatry
• Rheumatology
• General Practice or General Surgery

Proper specialty alignment ensures the assessment is clinically relevant and defensible.

An Independent Medical Examination is a structured, evidence-based clinical evaluation designed to provide objective medical clarification. It is not treatment. It is not advocacy. It is an impartial assessment grounded in expertise.

When conducted by experienced specialists and aligned with the appropriate discipline, the IME process supports transparent, clinically sound decision-making.
