The thing is "Soft Landing" or "Temporary Landing" are slang words used here on the forum to describe a situation where the PA/dependents "land" in Canada "activate the Permanent Residence" and then go back to their home country to be done with their commitments like sale of a house etc,. According to IRCC, there is no such thing as "soft landing" - this term was introduced by the members of the forum. You will not find this in IRCC manuals. When you land and the officer says "Welcome to Canada
", you are officially a permanent resident and you are eligible to receive a PR card.
Having said that, you can either provide an address at the time of landing OR you can provide IRCC an address within 180 days of landing. If you do not do either of the aforementioned things, you will have to fill in a new application to receive a PR card.
If you are planning to live at the same hotel for 45 - 60 days, then you can give the hotel address and if the officer asks why you are providing a hotel address, you can tell him that you plan to stay at the same hotel for XX days. However, if you are NOT planning to stay in the same hotel for at least 50 days, I suggest you NOT to give that address. Instead, you can give the address of a trusted friend/relative. If you don't know anybody in Canada, then do NOT give an address at the time of landing and tell the officer that you will update the address within the stipulated 180 days. When you rent a place to live, you can update your address online and your PR card will be sent to that address.
Good luck and all the very best!
