A Barrie man is facing charges for child sexual assault allegedly committed while he was a teacher.

OPP received a complaint in September of this year about sexual assault on a child.

Two OPP units were involved, and they opened an investigation.

It was found that the allegations date back to September 2004 to June 2005 when the man was a teacher in Barrie.

The now 61-year-old is living in London, and has been charged.

The investigation is ongoing.
