　　There is no word yet on who might be responsible for the hostage situation, but TVA Nouvelles describes a “group” of suspects and says a ransom demand has been made, so it seems like this isn’t a lone-gunman-style scenario. Montreal Police tactical teams continue to arrive on the scene.

　　We’ll keep you updated as this story develops and sincerely wish for a quick and safe resolution to the situation.

　　Update 1: According to CBC News, this situation may have been sparked by an armed robbery...

　　Police have told Radio-Canada's Kim Vermette that the operation near the Ubisoft building in Montreal seems to be related to an armed robbery.

　　Update 3: Ubisoft has commented on the situation via Jason Schreier, saying they are "aware of the situation and working with local authorities."

　　Clearly something scary happening at Ubisoft Montreal, but be wary of misinformation on Twitter. Employees tell Bloomberg they've received security instructions but don't know what happened. Ubisoft PR says: "We are aware of the situation and working with local authorities."

　　Update 4: There is some indication this may be some type of swatting-style hoax, but Montreal Police have not confirmed that.

　　Update 5: Some Ubisoft employees are being evacuated from the building.
