Canada Post may have accidentally delivered your package to the wrong address. Postal workers may occasionally drop packages at your neighbours’ homes or wrong mail box. Ask your neighbours if they saw it or simply look around their premises. You may also check the community mailbox.Postal workers may also have scanned a package as “successfully delivered” but it will actually arrive the next business day. Please allow a few extra business days to see if your package arrives.
From Canada Post:
“The investigation involves contacting the addressee to confirm delivery, or to better understand how they receive their mail and, as applicable, if they checked: with the front desk, security or mail room at the receiving address to see if someone else accepted the item on their behalf; their Community Mail Box for the item or parcel compartment key; around their property to see if the item was left in a safe location or in a mailbox attached to their home. In rare cases, a delivery scan is entered into our system before the item is delivered. If you become aware that the addressee has received the item before we contact you, simply reply to this e-mail indicating the item has been received.”
