Prior to joining ABC News, Gizbert worked as a correspondent-producer for CJOH-TV in Ottawa, where he produced in-depth features for Sunday Edition, the national current affairs programme.

Early articles include a review for Ottawa-based radio station CKCU on Elvis Costello's performance at the Heatwave Festival in 1980.

[2] After being fired by ABC News in 2004, Gizbert fought and won a wrongful dismissal case against the network,[3] in which an employment tribunal awarded him $100,000 in compensation.

He pitched a media analysis show to the network The Listening Post and has hosted the weekly programme since the news channel's launch in 2006.

Aaron Barnhart, TV writer for the Kansas City Star, wrote that Listening Post "might be the best media-critique program in English anywhere.

"[6] Stewart Purvis, former editor-in-chief and CEO of Britain's ITN, said "The Listening Post has delivered," and that its real value "is the breadth of its monitoring beyond the mainstream".
