The WC Act excludes mental stress as a compensable condition, except when the disablement of mental stress or a disablement caused by mental stress is the result of an acute reaction to a traumatic event.
A successful claim for mental stress requires three conditions be met:
For workers diagnosed with PTSD by a qualifying psychologist or psychiatrist, WorkSafeNB does not need to assess whether there was a traumatic event, as the occurrence of a traumatic event is inherent to the PTSD diagnosis. In these cases, WorkSafeNB will only need to determine if the traumatic event arose out of and in the course of the employment.
For emergency response workers covered by the presumptive legislation, when the emergency response worker is diagnosed with PTSD by a qualifying psychologist or psychiatrist, the PTSD is presumed to have arisen out of and in the course of employment unless the contrary is shown.
WorkSafeNB adjudicates all mental stress claims, except claims eligible for the PTSD presumption, using the criteria outlined in Policy 21-100 Conditions for Entitlement – General Principles and Policy 21-104 Conditions for Entitlement – Tests of Time, Place, and Activity.
