The Ottawa Police Service announced charges Friday as part of its investigation into alleged historical incidents of sexual assault involving a minor.
The OPS sexual assault and child abuse unit said it began investigating a complaint regarding historical sex offences last fall.
Police said they have now charged 64-year-old Jacques Chagnon of Ottawa with several counts of indecent assault, sexual assault on children under 16 and gross indecency.
Dating back to the 1970s, the alleged incidents involved a female victim and occurred in Ottawa and Quebec, police said.
