|SWAT team entering a house across the street at 4:30 pm
My guess is that this is related to the Oakville gun-shots incident. The woman that vacated the Oakville residence at 3 pm may have told police that the man still inside had a connection to this rooming house. Perhaps he (or a relative of his) is a tenant herein. I did spot a Halton police vehicle on the street after the SWAT team had left.
