1st PR Portal email -- Read it carefully and respond as requested.
I recommend to choose option A (all family members same email ID). press reply and Copy paste the UCI etc etc details for each family member and fill it in carefully. Please don't write stories. Will confuse them.
When you respond, usually within a day, they will send you username and password (don't create this yourself) for the PR portal. Login to the portal.
After login -- Then you will upload a 70x50mm digital photo on this portal (you can access it with the username and password they will send you). The forehead to chin length is also specified in the PR photo spec. Please follow it to the book to avoid waiting until the next life for PR card.
After login -- Also confirm that u r in Canada (whole process mandates that u need to be inside Canada)
Again within a day or few days later, you will get an email. Once logged into this new portal (the same portal you logged on after 2nd portal email), you will see eCOPR document for each family member.
At this point, your GCKey will show approved and show you just the COPR number (starts with Txxxxxxxx). Congrats, you are a PR now (at this step).
(Optional) Use UCI, last name and Birth place details from passport to link PR card application to your GCKey as well (after you get eCOPR). This allows acccurate PR card tracking. The day it shows Approved for PR card application (number starts with Rxxxxxxxx), thats the day the card is shipped to you. Dont stress out too much however, I could only link my app and daughter's app but not my spouse. Waiting for PR cards now.
Good Luck
The PR card is just for allowing you to travel internationally. Canadian PR card also allows you to travel Visa free to Mexico and many countries south of it + Qatar + ofcourse, other countries your passport originally allows.
Apply for SIN(permanent - walkin or apply online) and new health card (with a lot more validity)
