Most Canadian financial institutions are members of Interac, a multi-bank ATM network founded by RBC, CIBC, Scotiabank, TD, and Desjardins Group in 1984. Before the presence of white-label ATMs, most Canadian customers were only charged the standard Interac network transaction fee when a customer was using an ATM not provided by the bank that held their account. As the Interac network was opened up to more independent sales organizations (ISOs) and the potential for additional revenue from service fees were made available, most banks elected to impose the service fee in addition to the revenue that was generated from the Interac fee.[7]
