Quebecor Media is using an apparent threat of legal action to get CBC/Radio Canada to take down information about the Quebec media giant that it released on its website earlier this week.

“Quebecor Media considers the information published on these pages to be false and defamatory and published maliciously, without prior verification, in order to interfere with the testimony of Quebecor Media’s CEO in front of the House of Commons’ Standing Committee on Access to Information, Privacy and Ethics,” the media company said Friday in a statement.

Responding, CBC spokesman Marco Dube in a statement said the pubcaster was not “surprised” by the formal take-down request from Quebecor Media.

“We’re analyzing the letter and we’ll respond in due time,” the spokesman added.

Ahead of an appearance this week on Parliament Hill by Quebecor president and CEO Pierre Karl Peladeau, the CBC released its criticisms of its rival in a document titled “What Quebecor won’t tell you about its attacks on the public broadcaster” that accused Quebecor of using its media outlets to pursue a campaign to undermine the CBC.

Quebecor on Friday said the CBC, by alleging the Quebec media company was “hiding information from the public or being less than truthful in its reporting or public statements,” aimed to tarnish its reputation.

“In addition to the immediate removal of this information, CBC/Radio-Canada is put on notice to publish on its website an apology and the press release put out by Quebecor Media on Oct. 19 2011 to set the record straight,” Quebecor told the CBC in its formal notice letter.
