In January 2020, the Senior Investigator was reassigned in order to protect the integrity and objectivity of the investigation after voicing an opinion implying civil or criminal liability. The TSB labelled the comments made to The Fifth Estate journalists as "completely inappropriate" as the mandate of the TSB is to make findings as to causes and contributing factors of a transportation occurrence, but not to assign fault or determine civil or criminal liability. The CBC documentary pointed out what seemed to be a problem, where the private police service of CP Rail investigated the accident. A CPPS officer was also resigned over these circumstances. As of June 2020, the investigation is ongoing.
