Three people are arrested and face dozens of firearm-related charges after an incident that begins with a gun call in downtown Toronto and ends in Mississauga with a fatal police shooting. According to reports, the Toronto firearms investigation is triggered by a call on Wednesday reporting a person with a gun near a downtown location. Officers subsequently locate and investigate the situation in Mississauga, where a 19-year-old man is fatally shot by police early Thursday morning.

Authorities say the three arrested individuals face a total of 42 charges, largely related to the unlawful possession of a firearm. One of those charged is a 17-year-old girl, and the charges include offences connected to weapons and possession. Details about the investigation and the circumstances leading to the shooting are still developing, with reporting focused on the arrests, the number of charges laid, and the link between the original gun call and the later police operation in Mississauga. The matter continues through the court process.
