Appreciate your input. I am in exact same situation.
Since your PR tracker shows all sections as complete, but you haven’t received the Portal 1 email, it’s likely that your application is in the final review or queue for approval. Here are a few possible reasons for the delay:
Final Officer Review – Even if all steps are marked as complete, an officer still needs to do a final review before sending the Portal 1 request. This can sometimes take weeks.
Batch Processing – IRCC may be processing approvals in batches, and your file could be in a queue waiting for the next round
Security Screening Completion – If security assessment was the last step marked as “Completed,” there might be an internal delay in transitioning your file to the final approval stage.
Administrative Delays – Sometimes, applications remain in the system even after completion due to internal processing delays or system updates.
Since everything is complete, you’re in the final stretch. If you don’t receive Portal 1 within a few weeks, you could raise a webform to confirm the status.
