Cannick has been a voice and an advocate for many causes. She led a campaign to retire white gay comedian Charles Knipp's character Shirley Q. Liquor, a self-described inarticulate black woman on welfare with 19 kids. In 2005, she advocated to help make sure that the Los Angeles City taxpayers did not foot the bill to honor a homophobic black pastor. That same year, she helped lead a protest against the "Tookie Must Die Hour" on KFI-AM with talk-show hosts John Kobylt and Ken Chiampou. Stanley "Tookie" Williams was the founder of the Crips gang and scheduled to be executed after being convicted in the 1979 killings of four people. Cannick also was the last person to interview Williams before his execution. She would go on to face off against KFI-AM again after talk-show hosts Kobylt and Chiampou made fun of Whitney Houston after she was found dead in a bathtub at the Beverly Hilton calling her a "crack ho." Several years later Cannick criticized oKFI-AM morning show host Bill Handel for calling Florida Congresswoman Frederica Wilson a "cheap sleazy Democrat whore" on air.
