Canadian efile

EFILE is the system used by the Canada Revenue Agency as a means for electronically transmitting tax returns. It became a national program in 1993. EFILE is only available to professional tax preparers and is not to be confused with the publicly available NETFILE. EFILE is a form of Electronic Data Interchange.
