Here's an update: Foreign Electronic Funds Transfer Form is now available! The payment will be issued in the appropriate currency known to be accepted in the country where the electronic funds transfer will be sent. The final amount will be calculated based on the exchange rate on the date of the payment.
If you are one of those affected by the changes (filed before Feb 27, 2008), you will be receiving an email from FSWFeeReturn@cic.gc.ca for the instructions.
