If I can add pictures, will be easy but I don't know how....
So.. I will just explain how to link your applicaion.
1. Sign in CIC useing GCKey
2. You can see
Add (link) your application to your account, click it
or
https://www.canada.ca/en/immigration-refugees-citizenship/services/application/account/link-paper-online.html
then sign in
Next, you can see questions
provide the following information
1. Category - permanent residence
2. Sub category - Family class (Spuse or common-law)
3. Add detail - choose family, given name/ or UCI, family name
4. Personal information - I put my passport number
5. Province, city, current marrital status
6. Number of family number - if you applied just yours(no additional dependant) with sponsor then put "2"
I also linked my OWP the same way
Just choose Category - temporary residence and Sub category - workpermit
I hope it would be helpful for you guys.
