Two people were killed, including a Toronto police officer, following shootings in Mississauga and Milton on Monday afternoon.

As news of the shootings broke, it soon became clear that Halton and Peel police were looking for the same suspect - a man driving a black Jeep Cherokee.

An emergency alert for an ‘active shooter’ was then issued. It was ultimately rescinded after the suspect was located in Hamilton minutes later. Police later confirmed that the suspect was dead and that the Special Investigation Unit was investigating.
