Hickie first won the constituency of Prince Albert Carlton in 2007 by 61 votes and was re-elected in 2011.
The former police officer served as minister for corrections, public safety and policing from 2007 to 2009.
He was removed from the post in a shuffle, but returned to cabinet in 2010 as minister of municipal affairs, a job he held until 2012.
He most recently served as legislative secretary to the minister responsible for Saskatchewan Government Insurance and was tasked with leading an all-party committee on improving traffic safety.
Hickie was a constable in the forensic identification unit of the Prince Albert Police Service and says he plans to return to the force after completing his term.
