[1] After finishing his high school career, Clermont played for the Regina Rams of the Canadian Junior Football League (CJFL).

[5] After the 1998 season, the Rams left the CJFL in favour of affiliation with the University of Regina to play Canadian Interuniversity Sport (CIS) football in the Canada West conference.

[6] He was named the CFL's Top Canadian in addition to securing a spot on the Western Division All-Star Team.

[6] Clermont was back in the lineup in time for the playoffs, and saw limited action as the Lions captured the 2006 Grey Cup with a 25–14 victory over the Montreal Alouettes.

Clermont had an injury plagued season in 2008, leading head coach Wally Buono to deem him expendable.

Clermont signed a contract with the Saskatchewan Roughriders on December 12, 2008, finally being afforded the opportunity to join his hometown team.

[12] Although fans expected much from Clermont for the 2009 season, his role on offence was limited as he only caught 23 passes for 317 yards and was a healthy scratch for two games.

His first touchdown for the Roughriders was scored on November 14, 2010, at the end of the first semifinal game of the season, taking Saskatchewan to a 41-38 victory against the BC Lions in double overtime.
