The former principal of a small Catholic school in northern Ontario has had his license revoked by the Ontario College of Teachers for ignoring the repeated sexual abuse of students by one of his homosexual partners.

Jacques Perron was found guilty of “professional misconduct” earlier this year and was barred on Wednesday from reapplying for his teaching license for at least five years.

The former principal of a French-language Catholic school had hired two men, Pierre Grondin and Jannick Gelinas – with whom he was sexually involved – to work at the school. Grondin was hired as part-time school custodian and Gelinas as school secretary.

From 2003-6, Grondin exposed himself to male students in the classroom and in a hotel while on a school trip, sexually abused an intellectually-challenged male student several times a week for a number of years, and sexually abused two sisters while filming them. He also harassed staff and enforced Perron’s unwritten policy of no dissent.

The discipline committee of the Ontario College of Teachers ruled in January that Perron “acted inappropriately and incompetently, violated the ethics of the teaching profession, and failed to carry out his professional responsibilities”.
