Hi Harman12 on Landing appointment/ interview first you have to register to the receptionist and show your invitation letter and all documents requested, then he will give you a number for you to wait once your number called go to the window, present all the documents stated on the invitation letter and the immigration officer would asked you some questions like have you ever been committed crime or deported in Canada? When is your first entry in Canada?When is your last entry in Canada? And also the sponsor must show his/her valid identification with address on it and the immigration officer would ask some questions too or just confirming that the sponsor responsibility and after less than 10mins you’re done the Immigration Officer will congratulate you and explain the benefits of being a PR. In Etobicoke the Service Canada is also in the same bldg so after your interview the Immigration officer would tell you to go there to change your SIN number and you can get right away your new permanent SIN number, the IO Will give you a copy of a printed COPR with the validity so you can use it as an identification when needed. They will mail to you the actual PR card (1-8weeks waiting or more) but on the IRCC website the current waiting period for the new PR card is only 13 days. Hope it help you a little bit. Congrats!
