Over the weekend, Toronto police deployed dozens of additional officers to deal with a recent spike in gun violence in the city.
Hours after a shooting took place outside a restaurant in Toronto which left one dead and 13 injured, a short video uploaded on Twitter shows the alleged gunman opening fire. He said police don't know what prompted the attack but are investigating all possibilities.
Police Chief Mark Saunders said the gunman exchanged fire with officers and died at the scene.
Toronto Police said they had responded to a call at around 10:00 pm (0200 GMT Monday) in the city's Greektown district. Witnesses said they heard 20 to 30 shots.
"We just ran. We saw people starting to run so we just ran", he said.
Jody Steinhauer told CBC News she was at a neighborhood eatery with her family when she heard what sounded like 10 to 15 blasts of firecrackers.
Police said it was too early to comment on the motives behind the attack.
Police work the scene of a shooting in Toronto on Sunday
One woman was killed in the shooting spree and 12 people were injured, including a 9-year-old girl who is in critical condition, according to police.
The incident occurred on Danforth and Logan Avenue at around 10:00 P.M. Police can not comment at this time on whether or not the shooting was gang-related. The chief has said that it will take time to fully understand what happened and that any video footage should be submitted to the Police. However, preliminary reports suggested that "multiple people were shot at" and that "the victims were spread across many blocks". In total, 16 people suffered gunshot wounds, including the shooter.
Paramedics, firefighters and police soon converged on the scene of the shooting in Toronto's east end, which has many popular restaurants, cafes and shops.
