I have a few questions to ask and seeking detailed responses. I will be travelling to Toronto (PoE) and then would want to stay in Calgary at relatives' place before flying a few days before the start of my classes to Vancouver (would be searching for accommodation near my university and would quarantine in Calgary). At the port of entry, do they check the booking of the accommodation in the city of our university (Vancouver in this case) or they would only check the details of the stay for the quarantine?
