Quick Overview:
The Function Ability Form (FAF) is a crucial document used by the Workplace Safety and Insurance Board (WSIB) in Canada to assess an individual’s functional abilities after a workplace injury or illness. It helps determine their eligibility for benefits and appropriate work accommodations. Here are five key facts about the FAF:

1. Purpose: The main purpose of the FAF is to evaluate an individual’s physical, mental, and cognitive capabilities to perform work tasks following an injury or illness.

2. Completion: The FAF should be completed by healthcare professionals who have expertise in assessing functional abilities, such as physicians, occupational therapists, physiotherapists, psychologists, etc.

3. Sections: The FAF consists of different sections focusing on various aspects of functioning like mobility, self-care activities, communication skills, concentration level, etc.

4. Importance: Accurate completion of the FAF is vital as it directly influences decisions regarding return-to-work plans and benefit entitlements for injured workers.

5. Jurisdictional Differences: Although the basic structure remains consistent across jurisdictions in Canada, there may be slight variations in specific requirements or terminology used within each province or territory.
