It was actually just a glitch and didn't happen to too many people. After 6 months that the PR application was completed and 30 days that a PR Card application was finished, they're taken down from e-CAS. I renewed my card in May, and exactly in the 30th day that the card had been mailed the information couldn't be accessed anymore. It didn't appear again; I mailed my citizenship application a week after getting my new card and got my AOR in late July.rfirmeza said:As per the PR line, it simply means that each person has a unique number with CIC, meaning any application submitted by you will be linked to that unique number.
That is why all your applications will be visible on the ECAS page (PR, Citizenship).
