1. After tracking your parcel on different sites, the tracking seem OK. Your parcel is On Route to Canada. I also found this:
Tracking # :RS078423404CN
Date / Time : 2016/09/28 - 16:47
Description :There is no information available for this international item. Tracking by Canada Post is not a feature for this product.
Service Type :International Inbound Registered

2. If your parcel goes through Vancouver Inbound Mail then you can expect the delivery of your parcel between 6 to 8 weeks. Normally almost all parcels from China are going to Vancouver.

3. Your parcel is fine you just need to wait for it and be patient.

Hope this help.
