The Admail is just a huge, huge money-maker for Canada Post. It charges the customer, 15 cents, 20 cents, 25 cents, even 50 cents per piece for Admail, and the customer brings it to the post office. A union person brings it straight to the carrier and they pay the carrier two cents or three cents per piece to deliver those items.
