The argument was lost three decades ago when Canada Post ceased to extend home delivery into new suburbs.

If it had been made on a density basis, i.e. if a suburban block meets some minimum density, it gets home delivery, then there'd be a case. But it wasn't: it was all suburban developments, regardless of design or density.

So why should urban areas be treated any different?

They just set themselves up for an eventual tipping point to be reached all those years ago: with continued suburban population growth, eventually a significant majority of the population would be without home delivery, thus making it easier to eliminate the service from those who still had it.

Which is where we are today.

One can't but admire the long term, if cynical, thinking and planning involved in it all.
