Had the same thing happen then a couple days later got the correct delivery confirmation. So, I'd give it a few days.
I spoke to USPS today...they say the package indeed reached Canada and they are now requesting it to be re-routed to China. Strange thing is that when I used the 800# automated tracking service it says that packet is in China. Online it indicates it is in Canada. The customer service reps also believe it is in Canada. Lord knows who is right!!
