Thank you for the question.
In large urban centres, it has been door-to-door mail delivery. In small-town Ontario and rural Ontario, it's still the mailbox at the end of the farm driveway. Also, in small-town Ontario, the older residents are picking up mail at the post office; they have a slot in the post office. The newer residents in the newer subdivisions are picking up from these superboxes or community-style boxes that are at the corners in the subdivisions.
