RY705868211CN was shipped on December 21 and left China for Canada on December 30. Unfortunately Canada Post doesn't provide tracking for this kind of parcel any more (Registered Mail, tracking number starting with R), and they give them very low priority when it comes to handling and customs clearance. Usually they will take between 30 and 60 days to arrive.

Next time, if you're able to choose a shipping method, you might want to go with ePacket (tracking number starting with L). These kinds of parcels do have some tracking in Canada, and tend to arrive a little faster (average 20-25 days).
