They are demonstrating to protest against the four arrests related to last Thursday’s metro smoke attack bombings, according to CTV.
Little is known about this student group and their members are not made public.
The group issued searing attacks on journalists but said it does not plan on physically attacking journalists.
François-Vivier Gagnon, Geneviève Vaillancourt, Vanessa L'écuyer and Roxanne Bélisle are charged with committing a hoax regarding terrorist activities, conspiracy and mischief over $5,000.
The terrorist-hoax charge could land them five years in prison.
The four accused are expected to make their pleas Monday before a judge at the Montreal courthouse.
A Montreal lawyer said he thought the terrorist hoax charge might not be strong enough because in this case, they might even have committed an actual terrorist attack.
It was reported that the main student associations were conducting telephone negotiations with the Education Minister, and any breakthrough will be announced.
The group is reported to be a more radical splinter-group of the CLASSE.
CLASSE leader Gabriel Nadeau-Dubois said his members had nothing to do with the bombings, and that they also have a sense that their semester will not be saved.
The green faction, a group of students opposed to the student protests, rallied in Montreal on Saturday for a return to class.
