In its statement of defence, the health authority says former CEO Athana Mentzelopoulos was terminated because of her 'own inadequacies' in performing her job.

Alberta Health Services and Alberta Health Minister Adriana LaGrange are being sued for wrongful dismissal by former AHS CEO Athana Mentzelopoulos.

Alberta's health minister has filed papers in court to formally reject allegations from a former health leader who says she was fired for investigating sweetheart deals, collusion and high-level political arm-twisting.

Alberta’s frontline health agency says it fired its leader earlier this year not because she was investigating corruption but because she was a profound failure at her job.
