Steve Proctor says the "sexist and offensive" chant posted on Instagram was led by student orientation leaders at the campus.
Proctor says the Labour Day incident occurred just days after senior school administrators and police met with student union officials and orientation organizers stressing the importance of discouraging sexism and sexual assault during frosh week.
He says the student union has apologized for the incident and promised the chant will no longer be part of frosh week activities.
He says all of the student leaders involved in orientation week and the three members of the student union executive will take sensitivity training.
