One man was charged with assaulting police and obstructing police. Two other men were also charged with obstructing police.

All three were expected to appear in Gatineau court in the coming days.

The Saturday night protest was declared illegal after a verbal altercation between protesters and police at about 9:30 p.m., half an hour after the march began.

But the demonstration continued for another three hours until the protesters returned to their starting point.
