You can give your friend’s address and he can courier it to you. Tell him not to use Canada post. You have to tackle two issues if you are planning to do soft in immediate future (this/next month): 1) H1B ban is in works but not sure when it will be announced (you will have atleast a day to get back into US) 2) This “may” be a bigger problem: IRCC has mandated 14 days quarantine the moment you enter Canada so you will technically be breaking the law if you try to re-enter US the same day, although, there may be exceptions.
One option which even I am thinking; My friend asked for extension of CoPR to IRCC and they replied with a standard email response. Hope this helps in your decision! See below:
