CBC News host Wendy Mesley has been suspended from hosting, pending an investigation, after she said she "used a word that should never be used" during an editorial discussion about race. "Last Thursday, senior management within CBC News were made aware of an incident involving Wendy Mesley. While we investigate further, Wendy will not be hosting The Weekly," CBC's head of public affairs, Chuck Thompson, said in a statement. "Respecting the privacy rights of our employees, we have nothing more to add." Mesley, whose program, The Weekly, aired on Sunday without her, took to Twitter on Tuesday to apologize publicly. "It was not aimed at anyone, I was quoting a journalist we were intending to interview on a panel discussion about coverage of racial inequality," she wrote. "I was careless with my language and wrong to say it. Regardless of my intention, I hurt people, and for that, I am very sorry. I am also deeply ashamed. "I immediately apologized to my co-workers, and recognize this is a word that no one like me should ever use. I made a big mistake and promise to change my behaviour." Neither Mesley nor Thompson clarified what word she used. Andray Domise, a contributing editor at Maclean's magazine, told CBC's Eli Glasner he doesn't know what word Mesley used but said he finds the incident "emblematic of what it's like to work in Canadian media and Canadian journalism: that everything is just a one-off scenario." "We want to look at it as a series of one-offs, little blunders that we can fix," he said. "But that's exactly how systemic racism works."
