Chris Whitaker has issued a statement saying the acts violate the school's core values of respect and inclusion.
Humber staff received reports of a Muslim student being harassed on a bus as well as anti-Muslim graffiti on campus.
He says both incidents followed the recent Paris terrorist attacks.
Whitaker says the harassment won't be tolerated.
Anyone who has information on similar incidents is being asked to call Humber Public Safety at 416-675-8500.
