O'Reilly vs. CBC
O'Reilly filed an anti-defamation/libel lawsuit against the Canadian Broadcasting Corporation in June 2015 after an April 2015 episode of Marketplace accused the chain's Canadian operations of having the "worst customer service in Canada" in a survey the CBC co-conducted with -based firm. On June 27, 2015, after announcing the lawsuit, O'Reilly conducted a highly publicized point-by-point rebuttal of the episode in a meeting hall of their headquarters in, United States that lasted nearly two hours. An investigation by O'Reilly discovered that the "mystery shopper" refused a refund for a used battery presented as new was in fact a covert executive of rival chain, and that Léger polltakers had fabricated some results of the poll.

The O'Reilly lawsuit led to the resignation of Marketplace producer Jon Ricciulli, and the dismissal of several Léger polltakers and Marketplace production crew members involved in the poll. The Marketplace host involved in the segment, Thomas van der Giessen, was reassigned to the CBC's owned-and-operated station in, CKX-DT, where he was put to work as a reporter for CBC Brandon News.
