The investigation was two months long, according to a press release on Friday.
It was conducted by the Regina Children’s Justice Centre, a specialized RPS unit that partners investigators with social workers to look into allegations of child abuse.
Police said the case involved a 13-year-old girl.
Antoine James Quewezance, 47, is charged with sexual assault on a person under 16 and sexual interference.
He was an acquaintance of the teen but not related to her, police said.
The Regina man was released on a recognizance and is expected to make his first appearance in provincial court on March 11.
