Have you been diagnosed with work-related Chronic Mental Stress between April 29, 2014 and January 1, 2018?

If the answer is yes; you may qualify for WSIB compensation but only if you file your claim with WSIB before July 1, 2018.

What is work-related stressor?

A work-related stressor would generally be considered substantial if it is excessive in intensity and/or duration compared with the normal pressures and tensions experienced by people in similar circumstances.

For example, work-related chronic mental stress could be the result of being subjected to workplace harassment or bullying.

Three conditions must be met for a person to be entitled to work- related chronic mental stress:

  • an appropriate regulated health professional, such as a family physician, provides a diagnosis based on the Diagnostic and Statistical Manual of Mental Disorders (DSM)
  • the person has experienced a substantial work-related stressor(s), like workplace bullying or harassment,
  • the work-related stressor(s) must have caused or significantly contributed to the chronic mental stress.


A worker is not entitled to Chronic Mental Stress caused by an employer’s decision or action that is part of the employment function such as: changes in working hour or productivity expectations, terminations, demotions and transfers.

When will the proposed policy take effect?

  • The policy came into effect on January 1, 2018
  • There is a short window to apply for retroactive coverage if a person was diagnosed with work related Chronic Mental Stress on or after April 29, 2014 and prior to January 1, 2018. Those claims must be submitted to WSIB prior to July 1, 2018.
