Non-tax resident status: bank, RRSP and TFSA?

There are a number of things in determining tax residency.

Primary residence is the first. If you don't have a place to live in Canada (having a rental is not a place you can stay), that's a big 'tie' you don't have. Owning rental property is fine.

Having a Canadian bank account is fine. "Getting rent" is a perfectly valid reason to still keep it. They should lose their provincial health care, though. Switch driving license, too.

Having a TFSA is fine, but may be taxed in the overseas location. Can't contribute to it, though. RRSP the same; can't put money in, but less likely for it to be taxed overseas as most places accept retirement accounts.

Brokerage no, but obviously they would have to update everything.The CRA will require tax to be withheld on any dividends on Canadian stocks. It'd be better to be with a brokerage in the country they are going to.

Thanks, that’s very informative-but as to brockages : what about RRSP / TFSA account with questrade or TD? Same as regular RRSP and TFSA, just not contributing would be ok, right ?
