Even the infrastructure is based on a single directive, the application is not. This is why each POE kind of has its own design and rules.
I realize that each province and indepent city has their own immigration rules. But, some things are national, like a valid ten your tourist visa in an exoired passport or the eChannel. If my wife went to the Exit Entry Administion and asked for her visa to be transferred, they would refuse to do it.
