Thanks mate. The consultant told me that I just need to rent out my home and take my family with me to become a non resident for tax purpose. Since I am paying my mortgage, he said there is no need to close my bank account. regarding other stuff, he said the following:
Credit cards: No need to surrender, but preferable
Driving License: No need to surrender, it automatically wont get renewed after the expiry date
OHIP: No need to surrender, it automatically wont get renewed once we stay out of Ontario for more than 6 months
Storage for furniture: No issues renting storage
Car: Either sell or end lease
I first I was a bit skeptical about this advice since this sounds too good to be true. But the consultant was recommended by a friend who has been using his services for more than 30 years now. Also, the tax consultant has more than 3000 clients in GTA with most of his clients in the Middle East.
Hope this helps.
