Chicago Sun-Times Publisher John Cruickshank has resigned to head Canadian Broadcasting Corp.’s news division, sources said Wednesday.

Cruickshank also is chief operating officer of the Sun-Times Media Group’s Chicago portfolio of 100 area newspapers. He will replace Tony Burman, who retired as CBC News editor-in-chief on July 13.

Overnight mail delivery has improved in Chicago since the Sun-Times reported in March that in-town delivery here ranked worst in the nation, according to an audit released Wednesday by the Postal Service.
