Canadian Imperial Bank of Commerce CEO John Hunkin has updated his letter to customers, first posted in the wake of reports we had about the bank inadvertently faxing confidential customer to individuals outside the bank, first to a guy in West Virginia, and then to a guy in Montreal. We also reported that other banks have also had some fax missteps. "As a result, the banks, through the Canadian Bankers Association, have recognized that we have a common interest in ensuring the confidentiality of client information and we are determined to work more closely together to address this matter," Hunkin writes. "In the meantime, CIBC is continuing its work to ensure that customer information is protected across our entire network. This activity has been assigned the highest priority within our organization and we will not rest until it is completed."
