Many countries use laser checks to process payments. However the check format can be different and elements on the cheque may vary. If you are doing business with Canada and making payments using Canadian cheques, you need to use Canadian format to be compliant with the CPA (Canadian Payment Association) standards. Canadian Payments Association (Association Canadienne des Paiements) regulates money orders, bank drafts, business checks, settlement vouchers, savings bonds and other forms of payment.
