Canada Post has held my parcel for 4 days with no scan. Is that normal for this route or should I start the process?
Canada Post scans are generated at the hub, so a silent tracking page is not evidence of a problem for the first 4 days.
What I have learned is that the 4 day mark is the point to start the process, not the point to panic.
What is the thing you check first now?
What do you do about the fee? Do you just pay it?
Do you contact the customs office or the carrier first?
Everyone is an expert until the first seizure letter. Side effects was my main issue with PayPal too.
Photograph everything before you open it. Ten seconds, settles most disputes.
File early.
Customs outcomes are not rulings. A parcel passing is not legal advice.
