The clean up at Montreal City Hall is underway after a rowdy protest outside by unionized workers got out of hand.
The municipal workers, including firefighters, pushed their way into city hall and council chambers tossing papers, overturning water glasses and unfurling a huge banner that read "Coderre...Voleur."
Social media lit up with pictures of the chaos, some showing police officers watching as protestors plastered red stickers on city hall.
Tonight's council meeting was delayed by the unruly protest but councillors have returned to work.
Mayor Denis Coderre opened council by saying they wouldn't be intimidated by the union tactics.
Councillors, including opposition ones, applauded the Mayor's comments.
