Did he give you a tracking number for the "returned" package?
A laptop is big enough and heavy enough that any service used would have tracking included, whether your seller is inside or outside Canada .
Use the number to follow the trip to you.
Personally I would allow 20 days for arrival from the shipping date on the parcel, which should also be in the tracking information.
No tracking number?
Assume it has NOT been fixed or returned.
Go to eBay and open a Not As Described dispute.
Include the tracking number you received when you shipped it back to him.
If you already did this, he would have been told to pay for Return Shipping. If you shipped it back yourself, you won't see that money again. Sorry.
Go back to the Dispute and demand a refund.
Note that you want a refund NOT a replacement or a repair.
If he says it is being returned, demand a refund.
If you get the unwanted laptop back, demand a refund.
You can also open a Paypal dispute for 180 days after payment, even if there has already been an eBay dispute.
PP demands that the buyer pays for return shipping.
If you can show that the laptop was delivered to the seller, you can ask PP to step in and Escalate to a Claim.
Note that you want a refund NOT a replacement or a repair.
If the seller does not refund, PP will and go after him for their money.
And as a third layer of Buyer Protection, if you back your PP account with a credit card, you can call the 1-800 number on the card about a chargeback.
