I have worked for Canada Post since 2004. In my first year on the job, it was the closing of 300 Saint-Paul. All I have known are cuts and closings.
I heard about the post office that is in town, in a very tourist-oriented part of town. That location sold various spin-offs, such as little Canada Post trucks, stamps, and lots of things. That post office made a lot of profit with those products. Then, overnight, it was decided to remove all of them. Those products meant it could turn a profit, but they abandoned that part to focus only on services, when it was those products that make the profits possible.
Personally, I have not seen a lot of innovation on Canada Post's part.
