Hi everyone,
My spouse received the AOR email yesterday and had my spouse link her application to her account. We tried the following and it worked first time. Hopefully that helps. Also, I just want to mention that I had sent my 2015 Tax NoA.
1. Log in with GCKey account
2. Permanent Residence - Family Class (Spouses)
3. Application Number and Unique Client Identifier (UCI) - Insert application number and UCI from email
4. City of Birth - Insert PA's City of Birth
5. Country of Birth - Select PA's Country of birth
6. Passport Info - Insert Passport number, issuance and expiration info
7. Other Application Info - Fill out the other application info as per your application (Province, City and marital status) and put '2' as the number of members in the application for sponsor + spouse (add +1 per dependent, if any)
8. Click on the 'Search for my application' tab
9. Then on 'Link my application' tab
Good luck everyone!
