Since I bank with Scotia Bank here in Canada, I had them do the work for me from here. Papers were sent back and forth between the two banks and I just signed things. It did take a couple of months though to do it. I wasn't in a hurry and they held the bank book in Negril so that when I got there all I had to do was go in and sign in their presence. I also had my bank transfer money to Negril.

It might be possible for other banks to do this as well.
