Dear Jimmi1977. Nothing to worry. I am 74 years old and in my interview at Scarborough on 5th feb the receptionist told me that as per IRCC a senior person is allowed one attendant for all questions and answers. In my case though I have good knowledge of English having CLB 7 6 7 7 IRCC offer asked few questions from daughter in law as to whether I am working or retired. Hi simply cheked my PR and landing paper and he has not even seen my Passport and told me that citizenship is approved and you will be getting invitation of oath from 2 to 8 weeks. In our group all senior citizen were allowed to sit together in waiting area along with one attendant and they have dealt with us within 5 minutes for each senior. Wish all success for your parents.
