Here are a few differences that I think are major factors.
Canada makes use of a lot more automation in the areas of sorting mail for delivery. The USA doesn't
Canada has privatized the post office retail outlets, in Canada you don't go to the local post office, you go to the local drug store (usually a Shoppers Drug Mart) and they have a post office counter. If you have parcels to pick up you do it there, if you buy stamps you do it there.
We don't have door delivery service everywhere either. They do box delivery in all the new areas and soon the older areas as well. The way this works is for each block, and sometimes combined with another block, there is a large mail box, with a bunch of locked boxes, kind of like cubbyholes, there is a locked cubby for each house, you get a key and they deliver all the mail to that box. This speeds up delivery a lot and allows larger areas to be covered by a single delivery person. I heard talk of them trying this in places in the USA and it didn't sound well received. (I like it for the security, no one can poach a new credit card or gov check out of my mail box while I am at work)
In Canada mail only comes Mon-Fri. No weekend delivery, which I also heard they are thinking about trying in the USA, it too didn't sound well received.
Canada's post office union was just threatening to strike again recently after just having one but they backed down. I think the major difference is in Canada they are willing to changes how things work to keep things cheaper and more efficient, in the USA it sounds like keeping the status quo is more important than fixing the problems.
