“There are armed people that are possibly at large and we are asking the public to stay vigilant and contact us with any information [...] We have over 70 units on scene, as well as our forensic units, tactical units and K-9 units. But, at this point, stay vigilant and report any suspicious activity”, Sgt. Iryna Yashnyk said, cited by 680 NEWS.

Police Chief Chris McCord said later that they had not determined whether the shooting was targeted, adding that there were multiple suspects armed with semi-automatic weapons and a lot of rounds fired during the incident.

Canada has very low levels of gun violence, particularly when compared with its neighbor the United States, which continues to have the highest number of gun deaths per capita of any developed nation; a minimum number of 33,000 victims annually, including hundreds of children, according to media reports.

Last year, two tragic events shocked the city of Toronto. A woman and a young girl were killed and 13 others injured in a July 2018 shooting in Toronto’s Greektown neighborhood. In May 2018, a blast ripped through the Bombay Bhel restaurant in Mississauga, injuring 15.
