A bomb disposal expert was called to Prince Edward Island over the weekend after military ordnance was discovered in Stratford.
On Friday morning, some young people found a device in an old barn and moved it to an adjacent property, police say.
The residents of that property called the RCMP when they realized it might be an explosive device.
A Department of National Defence ammunition technician from CFB Gagetown was called in to help.
The ordnance was transported to a secure location in Alexandra, where it was disposed of.
On Saturday, police searched the property where the original device was found and located a second military device.
It was also taken to the Alexandra range for disposal.
Police are advising people who come into contact with military ordnance or are in possession of it not to touch or move the items. They should contact police to arrange for proper disposal.
