You can have it ready at the warehouse, see infor from FED-EX:
Not available to receive your shipment? FedEx will hold your shipment at a nearby FedEx location at no extra cost. Some shipments may not be eligible for this service.

Yes, I, too, got my notification. It says it's being shipped by fed ex and that it was picked up in Middletown, Pa! That's less than two hours from me!!
MY MISTAKE! My iPad is NOT in Canada it's here in California, Ontario to be exact. That's 4-5 miles from my home. So they did have stocked warhouses arounf the US.
