The number of tents at the pro-Palestinian encampment on McGill University’s downtown campus have tripled since Saturday, according to university officials. 

Montreal protesters set up about 20 tents Saturday afternoon with the intent of staying on McGill University’s lower field “indefinitely.” They joined a wave of pro-Palestinian demonstrations held on campuses across the U.S.

In a statement published Monday, the university’s media relations office said the situation with protesters on campus “shifted significantly.”

“We have become aware that many of them, if not the majority, are not members of the McGill community,” the statements reads. 

University officials also said they saw video evidence of “some people using unequivocally antisemitic language and intimidating behaviour” on campus. 

“We condemn this in the strongest possible terms and will act quickly to investigate,” university officials wrote. 

Sasha Robson, a member of Independent Jewish Voices McGill who was at the encampment overnight Monday, told CBC News there were no reports of issues overnight.

Throughout the weekend, McGill University’s media relations office said the protest had been peaceful. On Saturday, officials said a university security staff had instructed protesters to remove their tents, but they refused.
