Malcolm Kirk, who was named executive editor of the San Francisco Examiner in December, has left the paper and is returning to Canada. CanWest MediaWorks Publications Inc. announced today (July 7) that Kirk has been appointed publisher of the Calgary Herald. Kirk served as editor-in-chief of the Calgary newspaper from 2003 until 2006 and has experience at several of CanWest’s other newspapers, including the Vancouver Province and the Montreal Gazette, the company said. In San Francisco, Kirk had replaced Vivienne Sosnowski, who was executive editor of the Examiner for 17 months before being transferred to the Washington, D.C., Examiner. No word from the Examiner on why Kirk left or who will replace him.
