Peel Police say four people were shot outside a home in Brampton this morning.
Police were called the Julian and Fitzpatrick drive area, near Castlemore and The Gore Road just before 6 a.m.
Police say all the victims are expected to live.
They say officers were called to the same home last night for a noise complaint. They say there was some kind of gathering but can't say how many people were there.
Police are also looking into suggestions from neighbours that the house had been rented out on Airbnb.
So far, there's no information on suspects
