Kathleen Petty is a Canadian radio and television news journalist. An anchor for CBC Newsworld from its launch in 1989 until 2006, programs she hosted for the network included Canada Now and CBC News: Today from Calgary with co-host David Gray.
In 2006, Petty moved to Ottawa to host programming for CBC Radio Ottawa, including the local morning show Ottawa Morning, the provincial Ontario Today and the nationally-broadcast The House, a programme about Canadian politics.
On May 31, 2011 Petty announced that, as of fall 2011, she would be giving up both roles to move back to her native Calgary to take a position hosting the CBC Radio Calgary morning program Calgary Eyeopener. On August 11, 2011, however, Petty announced that she was "delaying a move from Ottawa to her hometown of Calgary so she can deal with a health issue".
In October 2012, she revealed that she had been in treatment for breast cancer.
