Professors moved classes online and protesters blocked access to classrooms at McGill University this week as a three-day student strike kicked off.

“Anti-Israel protesters are physically blocking access to lecture halls inside the Bronfman building and disrupting classes, preventing fellow students from accessing their right to education,” wrote the pro-Israel advocacy group B’nai Brith Canada on X on Wednesday.

“Protest is a protected right — intimidation is not. No student should have to choose between their safety and their education. Disrupting classes, harassing students and faculty, and hijacking campus spaces is not activism, it’s dangerous behaviour that has no place on a Canadian campus.”

On Thursday, Montreal police were on site to moderate protests and counter-protests.

“Police officers were there to make sure that those two groups (don’t) merge together and commit any criminal acts,” Agent Manuel Coupre told National Post in an interview.
