I could talk about the safety review conducted by Canada Post of each mailbox, of each house laneway and walkway. Canada Post will talk with residents to determine where mailboxes could best be located from a safety standpoint for their employees and of course, for customers.
However, some mailboxes have been in the same location for a long time. If a recommendation were to be made by Canada Post and by residents, I'm certain that the solution will have already been discussed. In some cases, mailboxes were moved for these very reasons.
