Alberta’s front line health agency says it fired its leader earlier this year not because she was investigating corruption but because she was an “alarming” failure at her job.

Alberta Health Minister Adriana LaGrange filed her statement of defence in an Edmonton court Thursday, saying the former chief executive officer of the provincial health authority was fired because “she couldn’t do her job despite having been given many opportunities to do so.”

Health Minister Adriana LaGrange is alleging the former CEO of Alberta Health Services was unwilling to implement the government’s plan to break up the health authority, and made “incendiary and inaccurate allegations about political intrigue and impropriety” before she was fired in January.

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.
