Kilgour was first elected as an MP for Edmonton—Strathcona in 1979 as a member of the Progressive Conservative party. He quit the caucus of Prime Minister Brian Mulroney in 1990 because he opposed the implementation of the GST.

In 2005, Kilgour publicly quit a major federal party for the second time in his career when he left the Liberals over what he said were "about 10 issues" with the party's conduct — including the sponsorship scandal and its plans to legalize same-sex marriage.

Kilgour also cited Canada's unwillingness to take part in a multinational effort to stop the genocide in the Darfur region of Sudan as a reason for his departure.

Ottawa eventually sent humanitarian aid to Sudan, a move attributed in part to Kilgour's persistent and public calls for action.

Liz Sheridan, a veteran stage and screen actress who played Jerry Seinfeld's mother, Helen, on "Seinfeld," died Friday morning, her manager and friend Amanda Hendon confirmed to CNN.

Sheridan had celebrated her 93rd birthday earlier this week, Hendon said. She is survived by her daughter and son-in-law.

Though she had dozens of film credits, she was best known as Seinfeld's doting mother on his titular sitcom, which ran for nine seasons. She also appeared as the snoopy neighbor Mrs. Ochmonek on the alien-led sitcom "ALF."

Sheridan's death comes within two weeks of the death of fellow "Seinfeld" cast member Estelle Harris, who played George Costanza's mother on the series.
