Thank you very much, @Jeffuuright. That's exactly what I need to know.
Based on Hebatollah El-Kady's article ("GST/HST Reporting Requirements for Food Delivery Services"), it seems to me that Uber Eats should not be giving my personal GST registration number to the restaurants I pick up food from.
However, since they are doing so, I am obligated to remit the HST to the CRA if I understand you correctly. Thanks again for your help.
