More than 400 protesters were “kettled” and arrested last night in Montreal and mass arrests were reported in other cities in Canada as the student-led demonstrations gained even more momentum.

This came after at least 300 people were arrested and twenty were injured in Montreal during weekend clashes between police and protesters, according to CTV. The movement began after a proposed tuition hike of $1,625, which would be implemented over several years. Support rallies were held in some cities in the US yesterday with more planned today. Check out this photo gallery of the arrested—or those asking to be arrested—in Montreal posing with messages on signs.

From today’s report in Toronto’s Globe and Mail: “A peaceful evening march that began with people banging pots and pans in support of protesting students ended in the early morning hours with police kettling demonstrators and arresting 400 of them after officers were pelted with projectiles. Montreal wasn’t the only city to have roundups Wednesday night. There were also mass arrests at student protests in Quebec City and Sherbrooke.

“The nightly march, which starts from an east-end park, was declared illegal by police the minute it was scheduled to start but was allowed to proceed for almost four hours before a line of Montreal riot cops blocked part of Sherbrooke Street as the marchers approached. Riot squad officers had been marching on the sidewalk beside the front of the protest all evening. An order to disperse was given when it arrived at Sherbrooke Street because police had been pelted by projectiles and other criminal acts had been committed, Montreal police spokesman Daniel Lacoursiere said. The group had also apparently resisted going in a direction ordered by police.”

Interesting and complete piece on history of the movement (even going back quite a ways), the use of the “red square,” broadening issues and more.

—Quebec’s education minister says she is willing to meet with students but no new talks set so impasse continues. Also: the new anti-protest laws are “not on the table”… Trade unions outside Quebec have sent money “pouring” into the student strike fund…

A handy guide to ten key points to remember relating to the protest movement (for English speakers, since protest material has been largely in French and “misconstrued”), including that it’s more about student debt than tuition, since tuition is still relatively low there.
