Ontario Provincial Police say three people are injured and four are in custody after an early morning shooting in Caledon.

Officers were called to a residence on Finnerty Side Road after reports of gunshots fired around 5:15 a.m. on Saturday.

Ontario Provincial Police blocked off a large area on Highway 9 between The Gore Road, Patterson Side Road, Finnerty Street and Humber Station Road in response to an incident involving “some potentially armed people.”

They say a shelter-in-place advisory was issued and roads were temporarily closed in the surrounding area. Members of the public were advised to “take action to protect their safety while police work to apprehend the individuals.”

Police say several specialized units were deployed, including police dogs and crisis negotiators.
