I am with the CBA and we have been following your discussion. We certainly understand the concerns that you have with FATCA. However, you seem to be under the impression that Canadian banks are planning to willingly go along with the FATCA requirements and this is certainly not the case. In fact, the Canadian banking industry agrees with your concerns and we have been and will continue to fight to change the extraterritorial reach of FATCA and lessen the impact it will have on Canadian banks and their customers.
We have information on our stance on FATCA on our website:
