Im in Ontario Canada..of course there's a way to track the package..lol.
Geee
It usually takes about 10-12 days for anything to arrive from the US (I know cuz I shop a lot, and get packages every week). That is through regular mail most of the time. If your son didn't send the item with tracking, the guy in Canada could be just saying he didn't get the package yet (if it's worth a lot) and your son would have no way of knowing whether he did or not, without tracking or signature.
