Work capacity certificate

Before making a claim for workers’ compensation with an insurer, a worker will need a work capacity certificate from their doctor.

What is a work capacity certificate?

A work capacity certificate is a type of medical certificate that tells an insurer about a work-related injury or illness, and what treatment and/or time off work is needed.

These certificates are used specifically for workers' compensation related matters. They include a lot more information than a standard medical certificate.

What information is on a work capacity certificate?

A work capacity certificate provides important information to an insurer, including:

  • a worker’s full name and details
  • the type of injury/illness (diagnosis)
  • the date the injury occurred and how it occurred
  • what treatment is needed
  • whether a worker can return to work or if time off is needed
  • any restrictions in completing certain tasks or functions
  • any workplace changes or considerations that are needed to help support return to work
  • the details of the medical practitioner who completed the certificate.

Below is a sample work capacity certificate. Some doctors may use an older version of this form.

How is this certificate used?

The information provided on a work capacity certificate is used by an insurer to make a decision on a worker’s claim and to help them to understand how to best support a worker.

Information about a worker’s capacity for work, including what tasks they can do, will also be shared with their employer to help them plan return to work and suitable duties.

Submitting a work capacity certificate

It is a worker’s responsibility to submit a valid work capacity certificate when they make a claim for workers' compensation, or to confirm with their medical provider that they will submit it on their behalf.
