Students at McMaster University in Ontario, Canada, derailed an event featuring University of Toronto professor Jordan Peterson on Friday evening.

The event, which Peterson claimed was originally scheduled to feature a panel of three speakers, was whittled down to just himself after the school received threats for hosting the event.

Peterson was thrust into the spotlight after a video of him engaging with students over a controversial piece of Canadian legislation which would have made it a crime to address transgender individuals by anything other than their chosen set of personal pronouns.

As a precaution before the event at McMaster University, Professor Peterson had students guard the fire alarms around the building so that protesters couldn’t set them off in an attempt to derail the event.

On Friday evening, Peterson was unable to speak at his scheduled event McMaster University due to a group of students who shouted and blew horns. The students shouted “shut him down,” and “transphobic piece of sh*t” in unison, with one student leading the cheer through a megaphone, making it nearly impossible for Peterson’s voice to be heard over their noise.

After the protesters successfully shut down the event, Peterson and the students in attendance were forced to move the talk outside where he was able to continue.
