Yanwen tracking in canada

Hello, I have a few questions. One who delivers Yanwen packages in canada? If it is canada post, I have received a “international tracking number” that doesn’t work on 17track or the canada post website. Also my package has been “In delivery” in my city for over a day so when do they normally tend to come after that? Also is there any duties with yanwen my parcel is on the smaller side so I would assume not. Any help appreciated Thank You
