You can't link your application on CIC page?
Go to this
IRCC Secure Account page :
https://www.canada.ca/en/immigration-refugees-citizenship/services/application/account.html
if you already have an online account, Sign in via "
sign in partner" or
GC Key. If you don't have one, register and just create an account. When you're logged in, you find a link on that page:
"
Did you apply on paper or don't see your online application in your account? Link your application to your account to access it and check your status online. "
Click on "
Link your application to your account". Then, you must choose the
Category of your application, (Which is Permanent resident Card in our case). You can use either your
"family name and UCI" to find an application, or
"your application number and UCI" etc. You should enter other info like
DOB and
Place of birth as well. Just keep in mind, you should type exactly the same as what is written on your landing paper (without even a small difference, like comma or space. Just copy it). Then, click on search button. Keep in mind, if you choose
"family name and UCI option", and punch them in, you would find all your PR applications you have in CIC, and the system asks your permission to link them to your account. If you choose the
application number and UCI option, you would find an specific application ( if they have it in their system). For instance, yesterday, I used UCI and family name, and the system found one application for me and asked my permission to link it to my account. I didn't give the permission, since I've not got an AOR yet, and my PR renewal application has not been processed yet. So, I'm pretty sure it's my initial PR card application since 5 yrs ago.
If you already have a processed application in CIC, you would find your application in your
IRCC Secure Account page.
