if its with Canada Post:
When no signature or collection of funds is required
- If no one is home, we will leave the item if it can safely fit in the mailbox.
- If the item is too large to fit in the mailbox, at our discretion we will either:
- Leave the item in a safe location such as between doors, or with a neighbour, and leave a safe drop card, indicating the item's location.
- Leave a Delivery Notice Card informing the addressee of the pickup location.
Same goes for UPS
When a signature or collection of funds is required
- If no one is home, we will leave a Delivery Notice Card informing the addressee of the pickup location
If its with DHL they try 2 times then it goes to their nearest warehouse for a while. you pick it up there.
so it appears different companies each do it differently. hopefully your package isnt left on your porch for a week though. if thats a possibility i recommend asking a neighbor or friend to stop by and see if its arrived a couple times
