I don't presume to speak to what Canada Post management is thinking, but what I suspect is the problem here is that the leadership at Canada Post sees its commercial mandate as much more important than its public policy mandate at this point. If Canada Post management understood that, yes, they're a crown corporation with a commercial mandate but that crown corporations serve the public good and are frequently required to act in the public interest rather than just simply maximizing profits....
I think that's part of the problem. Canada Post sees itself as a commercial interest rather than a public institution.
