I cannot answer that from an economic standpoint. The City of Montreal views the mail as an essential service, not a matter of facilitating a task. For example, Canada Post refused to deliver mail inside a new condominium project in the borough of Rosemont-La Petite-Patrie, even though the developer was prepared to install traditional mailboxes. That was during the so-called moratorium in 2016. If Canada Post refuses to deliver mail inside an apartment building, I find it hard to see why anyone would be interested in this as a so-called business venture. If, as we said, mail delivery is an essential service, we must maintain home delivery for reasons of citizen access and safety.
