Ideally yes, ppl shd have permanent address.

But everyone is not able to secure a job quickly and hence moving from airbnb to airbnb (upto 6-7 months).

For them UPS box is a life-saver because at-least OHIP is taken care of while struggle for job continues.

OHIP and driver's license has your home address for a reason. If you get hurt people need to find your family. The cost of staying in an airbnb is higher than rent.
 
Good luck to Airbnb or po box numbers.

OHIP office will refuse all that and send you back.
Until you have a sufficient document from list 2, check online, proof of residency, than you can go gack to our main office and apply agsin.
