If you’ve selected shipping method which includes tracking number (typically such shipping method has Tracked, Expedited, Priority or Xpresspost in their name) then you can track it at CanadaPost website or you local postal service website.
If your package has been shipped without any tracking (typically shipping method contains “Air” in its name) then there is no way to find its location. You can only try to contact your local customs and post office to check if they have anything for you.
