Karl Richard Toft (June 30, 1936 – April 28, 2018) was a Canadian convicted sex predator and pederast who committed an estimated 200 sexual assaults while working as a guard at the Kingsclear Youth Training Centre in Kingsclear, New Brunswick. He was regarded as one of Canada's worst sex offenders. Toft was convicted of 34 sex-related charges and sentenced in December 1992 to 13 years in prison. In 1994, Toft appealed the sentence but lost. He served 11 years of his sentence and was freed. He was represented by Daniel Watters, who maintained that two-thirds of the allegations were untrue.
