The Canada Post shipping tool for the Canadian Library Materials Service administered by CULC/CBUC
Customers using the Library Books Shipping Tools version of Electronic Shipping Tools (EST) may use postage stamps (preaffixed, or affixed at a post office upon payment of the postage amount indicated on the shipping label).
If you usually pay for your Library Books shipments with postage stamps at a post office, you may want to purchase the postage stamps in advance, and affix them to the item prior to going to the post office. Simply affix the postage (amount is indicated on label) on the shipping label in the space “Place Postage Stamps Here”. This will save time at the post office when you’re ready to ship.
The benefit of depositing your shipment directly at the post office is that a receipt scan is made by Canada Post immediately and the shipment is in the system for tracking. If it is dropped into a Street Letter box it could take 24 hours before the box is emptied. Also parcels handed in at a the post office are sorted and shipped more directly than parcels picked up in a box (they would go to a central sorting facility before being separated out as parcels).
