François Bugingo has been suspended indefinitely from contributing to several Montreal media outlets, including 98.5 FM, Le Journal de Montréal, and TVA.
The suspensions come after La Presse reported the high-profile Quebec journalist fabricated and embellished some of his stories dating back to Sarajevo in 1993.
Bugingo released a formal statement in response to the accusations.
"I am committed to defending my integrity and proving my professionalism," Bugingo said in the statement.
He said he would be withdrawing from his public life temporarily, while he prepares a response to the allegations.
Bugingo said he and his lawyer are co-operating with his various employers to answer any questions or concerns raised by the report.
He apologized for any inconveniences caused by the situation.
