Thanks, Patel for the advice. I agree requirement is to provide only the last 10 years' personal details, however, when you read the Instruction Guide for the PGP2023 intake it indicates one exception: Schedule A – Background/Declaration (IMM 5669)
Exception: If you have not worked in the past 10 years (for example, you’re retired), you must provide details of your personal history since the age of 18. The resume or Curriculum Vitae (CV) that you provide with your application will help verify the information in this question.
That is why I was asking. The issue is that personal History also asks about City/ Town and Country and I do not have all the details of her travel history when she was in the Middle East during the 70s and 80s. During that period, my whole family used to visit back home once a year for around one month.
