Police called to the Montreal headquarters of gaming company Ubisoft on a hostage-taking report Friday said there was no evidence of such crime.
"No threat has been detected," and "no injuries are to be reported," Montreal police said in a statement Friday evening.
An investigation has been launched into the origin of the report.
Earlier in the day, officers cordoned off the area and evacuated employees, police said.
Montreal police tweeted that "specialized" officers were sent to a location that corresponds with the company's address. Police initially responded based on a 911 call, the Montreal department said.
"Officers are on site inspecting the premises," the department said Friday afternoon.
"We are aware of the situation and working with local authorities," the company said earlier in the day. "It’s important that we do not get in the way of their work at the moment."
TVA Nouvelle, a Canadian news television company, posted images on Twitter showing police officers running with their hands on their weapons.
The station also posted images that reportedly show a large number Ubisoft employees on the building roof.
Ubisoft is the home of hit gaming franchises such as "Assassin's Creed" and "Just Dance."
