Thanks for the information. I applied online for the SIN number change from temp to Permanent.1. When you take photo for PR card, studio/photographer will stamp their name, address and Date of photo taken behind the photo. In addition to it, you can write your full name, DOB and UCI behind the photo. For address change, attach a letter requesting to send the card to particular address. Or raise a web form to change the address after sending the photo.(I have attached a letter requesting to send card to new address). There wont be any space behind the photo to provide your address.
2. To apply for SIN, you can apply online. To apply OHIP, you can visit Service Ontario. But better call them before visiting. Depending on the location, they wont be allowing walk-ins because of COVID.
Since we've been in Canada for 2.5 years and are on OHIP already for that period, do I even bother going to change that as well?
