I may go out on a limb on here and try to speak for northwestern Ontario, but I certainly speak for my community. The simple fact is that if you're going to be a dog, you'll find a stick. People will always find something to complain about, no matter what you do.
I think the biggest thing that would affect our folks would be a dramatic—and I mean dramatic—cut in hours. Our hours have been cut a bit in small towns over the years. Staff have been cut over the years. It's still manageable. People still get their mail because it's easy to get: you go in, you put your key in the box, and you open it. The only thing that would really bother people is a dramatic cut in the hours when they could go into the post office.
