Police in Toronto say one teacher with the Catholic school board of the city faces charges of teenage sexual assault.
Police say that in March 2017, a man reportedly led the 15-year-old girl to her home to discuss school issues.
They claim that a teenager was sexually assaulted during the visit.
Police say 36-year-old Brian Ross of Toronto was arrested last week and was charged with sexual assault and sexual intercourse.
Inspectors say Ross recently worked for Sen. O'Connor's College from September 1, 2016 until February 18, 2019, and previously worked at Catholic School Marshall McLuhan from September 1, 2006 to August 31, 2016.
They say he was also involved in training athletics.
He is due to appear in the Toronto court on May 3.
