This website cannot be used to check citizenship applications as far as I understand. You must go to this website 
https://cst-ssc.apps.cic.gc.ca/en/login to create an account after receiving an AOR and then log into that account. My mother's account is stuck after the online application

Logically, "Language skills" and "Citizenship test" should be "Waived" because she was over 55 on the day of the application submission. Physical presence should be quick, it is just a matter of checking whether she did leave Canada and reenter on the dates that were written on the application (checking with CBSA) and checking with the CRA on the SIN to see whether she did file the taxes (of course she did, I filed it for her). In addition, they probably would run her name through Canadian police databases to see if she has ever been charged with or convicted of anything (she has not).
