Just going to copy my response from the other thread here.

Excellent idea, I really support this. In smaller towns and rural areas, not to mention seniors, that decision would have a real impact.

That being said, how do they plan to pay for this? I mean, the reason they cancelled door-to-door was as a costs saving measure through a combination of scaling down their workforce, increasing stamp costs, and collective bargaining.

Following CP's announcement back in December 2013, the National Post broke down the numbers back in December 2013:

Canada Post by the numbers

$1-billion: The amount Canada Post was expected to lose every year by 2020 if it didn’t adopt a new business plan.

$400-500 million: The annual financial benefit from eliminating door-to-door delivery.

$160-200 million: The annual financial benefit from increasing stamp prices

5,094,694: The number of Canadians who get mail delivered to their door and who instead will see community mailboxes built in their neighbourhoods over the next five years. Mail delivery will not change for 757,843 Canadians in rural areas.

$269: The annual per-address cost for door-to-door delivery, the most expensive form of mail delivery. The annual per-address cost of delivering mail to community mailboxes is less than half that, at just $117.

15,000: The number of Canada Post employees expected to retire or leave the company over the next five years. Canada Post says it expects it can cut labour costs through employee attrition and collective bargaining, not layoffs.

59: The price percentage increase of individual stamps from $0.63 to $1.

Where will this money come from?
