What do you need to change banks you want to join the Halifax bank?
You will need to have your finances in order so you don't get
any fees from having bounced checks and so on. Go to the Halifax
bank and open an account with the minimum deposit. You will want to
overlap the two accounts so that the changes to any direct deposit
or billing can be made (by you) to the new account and so that you
can be sure than there are no charges/checks hanging out there.
Finally, they can help you request a transfer of your leftover
funds from the other bank. However, you'll probably have to
personally close the old account.
