Moving back to India from Canada after 20 years

Went as a 22 year old, now 42 with 2 kids. Dad fell sick and wants to be with grand kids. I have properties and setup base pretty well here. My wife has decided to quit her job but I have requested to have an internal move close to India like Dubai or Singapore. Salary in India is not attractive (I might be wrong). Anyone with similar experiences? India honestly looks foreign to me, for eg I was looking at cars and can’t recognize one. Alto and esteem were what I was driving! lol let me know if you guys moved after decades and what surprises do I expect?
