Police arrested 84 people, including 27 on criminal charges, and used tear gas to disperse demonstrators at a night-time protest in downtown Montreal organized by a local anti-capitalist group called CLAC.

Hundreds of people gathered at at least three different locations around the city, well before the protests officially got underway at 7 p.m.ET.

The group called on protesters to cause the "maximum disruption possible" to businesses downtown.

However, the majority of the crowd were people carrying anti-austerity messages with no intention of vandalism or violence.

By 7:10 p.m., police had already declared the demonstrations illegal and began ordering protesters to disperse.
