HALIFAX - A Dartmouth man is facing 66 sex-related charges after a four-year investigation into allegations of sexual assaults at a youth correctional facility in Nova Scotia. Donald Douglas Williams, 75, was arrested at his home on Saturday.

Williams served as a swim instructor at the Nova Scotia Youth Centre in Waterville from 1988 to 2017. He faces serious charges, including three counts of sexual assault causing bodily harm, 28 counts of sexual assault, and 32 counts of sexual exploitation. Additional charges include sexual interference, invitation to sexual touching, and assault.

The Royal Canadian Mounted Police (RCMP) reported that the alleged offenses took place at the correctional facility between 1989 and 2015. The investigation, dubbed Operation Headwind, involved interviewing over 450 survivors and witnesses across Canada. Authorities also reviewed more than 9,800 documents as part of their inquiry.

Williams has been released and is scheduled to appear in provincial court in Kentville, Nova Scotia, on September 26.
