Caledon OPP say jewellery, electronics and unwrapped gifts were stolen after a break and enter at a home.
It happened on Finnerty Side Road near Humber Station Road on Monday.
It happened in the daytime hours between 11am and 1 o'clock when the suspect got in through the front door.
Police say they had reports of a person going door to door in the area offering puppies for sale around the time that this residential break in occurred, but it may not be related to the crime.
They're hoping to speak to anyone who may have more information.
