To everyone calling IRCC, and staying on thé queue for hours, I'm glad to tell you that it is over.
Kindly click on:
https://ircc-tracker-suivi.apps.cic.gc.ca/en/login to view detailed activities going on in your file.
It gives quite detailed tracker on what has so far happened on your application. What all the "ghost updates" you saw were actually. What activities have been completed and which are in progress or to be started. What all documents have been received, your document expiry dates like medicals etc.
You need to register first, make sure you're entering your information correctly else it will give you invalid error.
