First you have to check the seller's stated handling* time. Some sellers, like me, ship the same business day. Others allow one to three and up to five and ten business days in certain cases. This must also be factored into your wait time.
If your item was mailed from within Canada, waiting a week is the minimum to be expected. Domestic lettermail takes an average of seven business days and that does NOT include the day it is received by the post office, weekends or holidays. Given that you're speaking of tracking, however, that would lead me to believe you're talking about a parcel.
If your seller is Canadian and used Expedited Shipping, you would probably have your item within four to eight business days and up to 13 if you live in a remote or northern part of Canada. Only if you paid for XpressPost would you have it faster. Since that postage starts at about $15 for something as small and lightweight as a letter, I'm thinking not.
International shipments take longer. Waaaaay longer. Allow 15 to 20 business days. Check the tracking number your seller gave you again. Is it possible you've mixed confused the date provided? Or, more ominously, if this was an item shipped from overseas, it might be possible the seller is trying to scam you into thinking this item is yours when really it was sent to someone else entirely. There are a pile of unethical foreign sellers who play the wait-and-see game with new buyers such as yourself. Mark Day 29 on your calendar and if you don't have that item in hand, go to the Resolution Centre and open an Item Not Received case. And don't close it until you have your money back. Don't accept the offer of a replacement from a foreign seller, either. That is part of the game, meant to placate you until your deadlines to open an Item Not Received case is over.
If your seller is, in fact, domestic, you might grant them some extra leeway, depending on their feedback. After 30 days, if you still don't have it, you can open a case through Paypal.
Your Purchase History will provide an estimate delivery. Go by that.
*When you go to leave feedback for the seller's Shipping Time, set your expectations to their HANDLING time, please. If you picked the least expensive shipping cost possible because you wanted to save coin, please don't expect the seller to have gotten it to you by overnight priority. That's not reasonable. How fast did it leave THEIR hands? That's the standard by which you leave feedback. A decent seller shouldn't be held accountable for whatever happens when the postal system gets their grubby hands on it.
Good luck as you carry forward.
