Two top leaders of Teekay Tankers are leaving the company fold.

Teekay Corp said in a statement released late on Wednesday that president and chief executive Kevin Mackay and chief financial officer Stewart Andrade will “transition out of the organisation” by the end of August.

Their departures have set off a series of changes in which senior executives of Teekay Corp and Teekay Tankers have been promoted or given additional roles.
