A potential hostage situation is reportedly taking place at the building in which game developer Ubisoft's Montreal office is housed.

Canadian media began reporting a major police operation outside the Ubisoft Montreal headquarters around 1:30pm Eastern time. Montreal police confirmed that there is an "ongoing police operation" at the intersection where Ubisoft Montreal sits, adding, "We ask people to avoid the area. The SVPM is currently validating information and more details will follow."

Live-streamed footage from French-language outlet LCN showed a group of people together on the roof deck of the building behind a makeshift barricade seemingly constructed of folding tables leaning against the access door. Developer Eric Pope confirmed in a Tweet that the individuals on the roof were indeed Ubisoft employees, saying, "This is insane. This is my team on the roof."
