Shipping is not handled by eBay, which is an advertising venue.
Your item shows Shipped from China on December 8th and Delivered to Montreal on January 12, 2018.
If you did not receive it, start by asking your housemates if they have seen it.
If that doesn't work, go to the local Postal Outlet and ask about it. It may be being Held for you.
Go immediately, because the PO doesn't have room to hold packages for long.
