Let’s not forget also that if you live in a remote location, and somebody sends a parcel to you via UPS or one of the other private carriers, Canada Post is the one who gets it to the door (or local post office, if it’s a really small town).
It’s not profitable to get out there, but Canada Post must. The other carriers get to take a profit while forcing CP to take the loss.
Ah, that one’s tougher. Most of the time the sender isn’t paying for return service. For most advertising like that, anyway.
You can look at the postage on the top right… If it says “Personalized Mail” then it won’t be returned unless it says that it will underneath. “Postage Paid” or “Letter Mail,” or that extra note under “Personalized Mail” that says it will be returned (I forget the exact wording, but it’s obvious when it’s there), you can just draw a line through the name and address and leave it for the letter carrier or put it in a red box.
It’s still up to the sender to stop wasting their money, though.
