and his tenure as one of the hosts of CBC's The Fifth Estate, as well as his depiction in the movie Target Number One (known as Most Wanted in the United States).

Malarek entered the world of journalism in 1968 as a copy boy for Weekend Magazine, and joined The Montreal Star as a police reporter in 1970.

The 16-part CBC fictional drama series Urban Angel in the 1991–1992 season was also inspired by Malarek's life.

In The Fifth Estate episode "The One That Got Away", Malarek exposed police and prosecutorial misconduct that resulted in Calmar man Jason Dix's wrongful accusation of double murder.

In 2020, his 1980s investigation of the arrest of Canadian drug addict Alain Olivier in Thailand was dramatized in the film Target Number One (known as Most Wanted in the United States), in which he was portrayed by Josh Hartnett.
