Thousands of student protesters march through downtown streets of Montreal on July 22, 2012 in a demonstration against bill 78 and the tuition hike fees in Quebec province.
Security forces have arrested some 200 students marking the first anniversary of massive protests against tuition increases in Canada's eastern province of Quebec.
Police spokesman Jean-Bruno Latour said on Saturday that the protesters had been detained during a protest rally in downtown Montreal late on Friday.
The demonstrators demanded forming a commission to investigate the performance of police forces during last year's unrest that involved thousands of people against tuition hikes in the French-speaking province.
Some of the demonstrations turned violent, with many students detained during clashes with police.
The demonstrators eventually succeeded in persuading the Quebec government to cancel the tuition increases.
