The applicant sought Income Replacement Benefits (IRBs) beyond the 104-week mark following a motor vehicle accident in November 2011.
The insurer had paid IRBs up to February 2015 but terminated them.
The applicant argued that the accident caused a traumatic brain injury and exacerbated her pre-existing Borderline Personality Disorder and substance abuse issues, rendering her unemployable.
The insurer argued that the applicant was already unemployable prior to the accident due to her severe mental health and addiction issues, and that the accident did not materially contribute to her impairment.
The arbitrator reviewed extensive medical records and expert testimony, concluding that the applicant's downward spiral began well before the accident.
The arbitrator found that the applicant failed to prove causation under either the 'but for' or 'material contribution' tests, as her inability to work was entirely attributable to her pre-existing conditions.
The application for ongoing IRBs was dismissed.
