Peel District Police say the suspect worked at Camp Kennebec in Arden, Ont.  for 19 years, dating back to 2002. The summer camp specializes in young people, adolescents and adults with intellectual and developmental disabilities.
Campers often referred to the suspect as “Rocker Sean,” police said.
He also worked as an unregistered personal support officer.
In a press release issued Friday, officials said a suspect who identified himself as 47-year-old Mississauga resident Sean Jackson had been charged in connection with the ongoing investigation.
Jackson was first charged in April with possession of child pornography, access to child pornography and possession of child pornography.
In June, he was further charged with sexual assault, failure to comply with a release order and four counts of voyeurism.
The charges have not been proven in court.
Police believe there may be additional victims who have not yet contacted investigators and are urging anyone with information to contact the Child Internet Exploitation Unit at 905-453-2121 ext.  3490 or to contact Peel Crime Stoppers anonymously.
