Police in eastern Ontario say a 58-year old Montreal man face 20 charges following cases of sexual ssault involving children.
Officials add they happened at a camp site in Hawkesbury between 1995 and '98.
He allegedly assaulted four victims, girls and boys aged between five and 12-years old.
The suspect, who's name has not been revealed to protect the children, faces charges including sexual ssault and sexual contact with a person under 14.
A court appearance is scheduled for late August.
