If you take a look at the TD Commercial banking site -( http://www.tdcommercialbanking.com/cashmgmt/cheque_fraud_protection.jsp), you will see they offer a Cheque Fraud Protection program.
We have developed a system for PClaw to offer an integration with this system. We support the positive pay with payee match. It is an application called CFP Converter. In essence we take your cheque information, do the calculations and formatting and prepare the files for you to upload to your Bank. We support TD in production at present with other options in the near future. Let us know if you have banking requirements beyond TD.
