According to police, the woman "initiated an inappropriate relationship with a 17-year-old male student" between March and October 2014.
During this time-frame, the woman supplied the student with drugs and alcohol and the relationship increased over time, resulting in sexual contact on numerous occasions, police said.
Police noted contact happened during and after school hours but wouldn't say if it happened on school property. The school was not named.
The relationship became known to police after the student came forward. Police were notified and the child abuse unit began an investigation.
A Winnipeg School Division (WSD) spokesperson confirmed the woman was an employee at one of its schools but won't say which one or for how long she had been there. The division also won't say if she had worked at any other school.
The WSD is providing clinical services to the student and his family, including counselling.
The woman, who has been on administrative leave since October, was arrested and charged on Dec. 11.
The charges include:
- Administering a substance with intent to stupefy a person to have illicit sexual intercourse.
- Supplying liquor to a minor.
- Driving without as license or with an invalid licence.
