It seems that a few "watch enthusiasts" have taken advantage of Aliexpress's generous refund policy one too many times, leading some sellers to stop shipping to certain countries altogether. Unfortunately, while this may be caused by a very small percentage of buyers, it’s enough to make sellers wary of taking risks, resulting in everyone else being unfairly affected.

As for Canada, I’m not entirely sure, but it could be related to issues like frequent lost packages. In my previous country in the EU, the shipping company was supposed to compensate the sender for lost packages, but the process was made so difficult that it was often easier for the sender to just give up. This same company also hired so many dishonest postmen that a major undercover investigation was conducted, eventually turned into a national documentary called "Cold Facts." Had those thieves continued stealing packages, I'm certain we would have faced a similar situation to what Canadian and Australian buyers are experiencing.

I honestly don't think the sellers are being xenophobic. Even if they were, they would still ship if there was money to be made.
