Are you referring to https://portal-portail.apps.cic.gc.ca/signin?lang=en ?Update: we submitted our application for this new trv!
It’s pretty straight forward application in the new portal. Just attaching passport copies and documents/proofs at the end. And of course you have to pay.
They will send you messages in the portal and you also get something like the one in gckey screen where all the progress and details. There is even a progress bar.
I will be still with my spouse and daughter for 3 weeks so we only have 10 days or less not being together to know the result. Fingers crossing!
Am I right to understand that you have to get the invite code from https://ircc.canada.ca/visit-visiter/en/get-account-ircc-portal
I'm unable to find much of documentation on the official web page.
I think of tying to submit a request for my dependent step-child (my wife has TRV already)
