Premier Jim Prentice announced in Calgary on Saturday that Rick Hanson will represent the Progressive Conservatives in the riding of Calgary-Cross.
Hanson announced last month that he was retiring after seven years as police chief.
Friday was his last day with the force.
Prentice is expected to drop the writ as early as the end of this month.
Hanson joined the Calgary force in 1975 and spent virtually his entire career in the city.
