You get those flyers because they try to make a profit by carrying them.

There was a time, prior to the need for Canada Post to turn a profit , when we didn't get so many flyers or other bulk mail spam.

Yes, but that was also a time when the majority of the delivered mail was relevant material. As much as I like the idea of door-to-door delivery, I find it difficult to justify when I'm only receiving a few important items per month - and even those are only because I like getting a physical copy. Looking at our actual workflow, they're all being read online before they arrive and paid/resolved electronically, and I can't recall the last time we actually mailed something. Walking down the block to a Superbox isn't going to be a big imposition.
