A teacher from Richmond Hill has been charged following a historical sexual assault investigation involving a teenaged female student.

According to York Regional Police, officers began investigation on Feb. 3 after receiving information about sexual offences that occurred beginning in 2011 involving a high school teacher and a student under 18 years of age.

The name and location of the school are not being released to protect the identity of the victim.

“The accused has been working as a high school teacher with the York Catholic District School Board at a high school in the City of Richmond Hill since 2010. Investigators want to ensure that there are no additional victims and are asking anyone with information to please come forward,” reads a social media post from police.

Christopher Ng, 34, has been charged with sexual assault and two counts of sexual exploitation.

He is slated to appear in Newmarket court on March 17.

“A sexual assault includes any non-consensual contact of a sexual nature. York Regional Police encourages victims to report incidents of sexual assault, including historical offences,” the social media post reads.

“There is no statute of limitations for sexual offences and offenders can be prosecuted well after the date of the offence.”

Police also shared a guide for survivors of sexual assault.
