This is usually a message through Canada Post. Do you have a box number. Usually when Canada Post receives the parcel and scans it into the system, this message will come up. They have not had a chance to put the parcel card in your box yet. Be on the look out for a parcel card.
My best guess. This is a link where you can track the shipping number and it will tell you who the courier was.
