Some people are quite happy with Canada Post's Super-Mailbox (community mailbox). Other people are dissatisfied with the phase-out of door-to-door delivery, so there are many complaints and protests.
In order to achieve Maximum Satisfaction, Canada Post could offer an optional door-to-door subscription at extra charge, say $9.99 CAD/month. This way, some recipients who desire door-to-door delivery will have what they want, while Canada Post will have an economically sustainable business in an environment of declining volume of snail-mail letters.
