The Alberta Energy Regulator, also known as the AER, said its three executive vice presidents are no longer with the organization, according to an Oct. 23 news release.

The executive vice presidents include Mark Taylor of the operations division, Stacey Schorr of the stakeholder and government engagement division and Carol Crowfoot of the strategy and regulatory division.

The AER assigned Gordon Lambert as interim CEO while it searches for the permanent replacement of former CEO Jim Ellis. The recent changes came after an audit of the organization found "gross mismanagement" at the AER earlier this month.

Meanwhile, the board of AER and the Government of Alberta will continue its review of the organization.
