One thing they have a monopoly on numerous aspects of mail delivery, the service is not efficient, it cost the taxpayers a fortune, they're now losing money and their prices are increasing. As well I'd much prefer FedEx delivering parcels to my door then having to go to my mailbox to get a slip, then trying to get to the post office when they're open to pick up my parcel.
I want a better service and Canada Post in its current form seems incapable of providing it.
