A high school teacher in Toronto has been placed on home assignment after he was found in blackface during a Halloween celebration, according to CTV News.

Parkdale Collegiate Institute sent out a letter informing faculty, parents, and students of the incident. According to the letter, a number of students caught the teacher.

The letter also stated that the high school ordered the teacher to wash his face so to avoid further offence.

“Caricatures of peoples’ race or culture are not appropriate and are offensive and hurtful. Regardless of whether this was intended or not, it was racist and dehumanizing,” said the letter.

The teacher is currently facing an investigation by the Toronto District Schoolboard. He is on paid leave and will be working from home.

"On behalf of Parkdale CI, I acknowledge and regret the harm this incident has caused to students, staff and families and our shared school climate," said the principal.
