For delivery I just discovered that Purolator has this form for Single Shipment signature waivers found here:
https://www.purolator.com/en/support...ng-my-shipment
Under the heading "How can I have my shipments left without a signature?"
Here is a direct link to the PDF form you can print and fill out to leave at your destination:

As opposed to getting the sticker and waiving your signatures for ALL your packages.
