(FILES)Tens of thousands of students protest in this March 22, 2012 file photo against a 75-percent tuition hike at universities in Canada’s mostly French-speaking Quebec province, bringing downtown Montreal to a standstill. Since mid-February, students have held protests denouncing the Charest government’s decision to increase tuition fees, in one of the biggest student uprisings in the history of the French-speaking province. The government of Quebec invited April 23, 2012 two student organizations to meet to find a solution to the conflict.
