Bergeron made the original comments in his book, auvolant, c’estmortel.
Inside, he alleges the government of former U.S. president George W. Bush may have played a role in the Sept. 11, 2001, attacks.

"I wanted to shock people, because I was a writer, I was writing an essay and our objective when we do that is to shock people just for fun. I'm not in the that life anymore — I'm a candidate to run Montreal for the third time. That was in my previous life and I was a bit stupid at that time," he said.
