"Marcel is a very experienced coach who has had lots of success on the offensive side of the ball as a position coach, a co-ordinator and a head coach," Bombers head coach Tim Burke said in a statement. "He will add experience to our staff and will be another voice in our offensive meetings who our offensive staff can lean on to provide us with new insights and ideas thanks to his wealth of knowledge at the CFL level."
Bellefeuille returns to the CFL after spending three seasons as the Hamilton Tiger-Cats' head coach from 2009-2011. He was originally hired by the Ticats as their offensive co-ordinator in 2008 after spending time in that capacity with the Montreal Alouettes and Saskatchewan Roughriders.
Bellefeuille began his CFL coaching career in 2001 with the Roughriders.
Prior to joining the CFL, Bellefeuille won a Vanier Cup as head coach of the Ottawa Gee-Gees in 2000. He spent last season as a receivers coach with the United Football League's Omaha Nighthawks.
