Question) I was not home at the time of a parcel delivery can it be redelivered?
Answer) Canada Post does not offer the service of redelivering parcels. When a parcel cannot be delivered on the first attempt, a Delivery Notice Card will be left at the door. The address of the Postal Outlet, the phone number and the item details will be on the card. The addressee will be required to pick up the parcel at the location indicated on the card.
キッパリですね。
