Which phone numbers have you tried?
The usual purpose for this is for a courier (like UPS) to call before delivery to confirm you are home, so he can collect the import fees due.
In addition to your home phone, try your cell phone, your work phone, and maybe your mother or partner's phone.

It's also just possible that it isn't working because the seller does not ship to your location. Does she have a firm price for shipping to Canada?
