Cold Squad is a Canadian police procedural television series first broadcast in 1998 that followed the investigations of a part of the Vancouver Police Department Homicide Division tasked with solving cold cases, the titular Cold Squad, as led by Sergeant Ali McCormick. The cast of Cold Squad was diverse and changing, McCormick being the only character to appear in all 7 seasons. Some notable series regulars include Detective Tony Logozzo in seasons 1-2, Sgt. Frank Coscarella in seasons 3-4, Sgt. Len Harper in seasons 5-7, Insp. Vince Schneider season 1, Insp. Simon Ross season 2, Insp. Andrew Pawlachuk seasons 3-7, Det. Mickey Kollander seasons 3-6, Det. Nicco Sevallis seasons 3-6, Christine Wren seasons 4-7, as well as Det. Samantha Walters and Const. Ray Chase in season 7. Between the second and third seasons, almost the entire on-screen cast other than Julie Stewart were replaced. This along with the new sets, a significant revamp of the credits and theme music, and even having McCormick's hair change from auburn to dirty-blonde all contributed to a considerable reworking of the series.
