" We all know that because they are the shipper ONLY they can start a trace."
NOT true Brian, you were provided with the tracking number so you could keep track of your shipment
I don't have a horse in this race, so this is just a general comment.
As far as I know the original statement is correct. With a tracking number anyone can see where Canada post last scanned a package. However when the package haven't arrived by expected date, and there haven't been any status updates on the package in a while (And Canada Post is
really lousy with tracking), a shipper can call and ask for a trace on the package and request a refund on the shipping cost.
I've attempted to request a trace as a sender and the recipient of various packages, and in my experience when I was the recipient Canada Post was not able to put a trace on (They require origin and delivery postal code for a trace) simply because I didn't know the origin information for the package.
Trace can generally be requested over the phone after 5 pm on the "expected delivery date" of the time zone in which the package is being delivered. So if you ship from Ontario to BC, they'd want to hear from you only after 8 pm Eastern regarding the matter. Practically, this means "next day". You can request a trace over the web, but the form will require alot of information to be filled out, that you might not have (as a recipient). Calling over the phone is generally simpler, but takes longer. Occasionally one can find the postal code for the origin of the shipment by looking the address up on the web.
And, of course, it is the shipper that needs to get ahold of Canada Post if shipper wants to obtain a refund on the shipment being late, since Canada Post wants to know how much you paid for shipping.
So to summarize:
- With tracking number anyone can find out where Canada Post thinks the package is
- In order to put a trace on a package, one needs to know origin and recipient information, and since recipient commonly doesn't have the origin information, trace commonly needs to be done by the shipper
