Purolator has a form called "Customerâ(TM)s Authorization to Waive Delivery Signature Single Shipment Use" (a PDF is the first result in Google right now).
Whenever I'm expecting something from them, I print out one of those and put it on my door.
The only time that I've had trouble is when the shipment notification from the retailer gets to me after the delivery attempt has been made. In that case, I usually just go get the package at the depot (25km, sigh), but it may be possible to just call them and ask them to try again (and leave the form above on the door).
