Demonstrators in Montreal have continued to defy an emergency law passed by the provincial government in Quebec to restrict protests by students against planned tuition fee hikes. On Wednesday, more than 500 Montrealers were arrested - more than during the entire October 1970 crisis when martial law was declared in the city in response to actions by Quebec nationalists. The total number of those arrested in the current protests has now exceeded 2,500. The protest ... was declared illegal before it began, because organizers had not provided police with an itinerary, as required by a controversial new emergency law. Helicopters and riot police are an increasingly common sight on the streets of Montreal as a province-wide student strike passed the 100-day mark, but popular support only seems to be growing as the government attempts to clamp down on the strike. Small red squares, the symbol of the strike historically worn by Montreal students supporting free tuition, are everywhere in the city - cloth pinned to people's lapels and daubed onto signs and walls. Families and older residents are increasingly common sights at protests as well, demonstrating against Bill 78, which places restrictions on protests of more than 50 people. The bill imposes fines of $125,000 a day on student unions that defy its provisions, and student leaders shown to support unplanned protests can be fined up to a maximum of $5,000.
