Amending returns

You can file amended slips electronically even if you filed the original return(s) on paper or on electronic media. See Filing information returns electronically.

Additional slips
You can transmit additional slips. After you file your information return, you may discover that you need to send us additional slips. If you have original slips that were not filed with your return, file them with a separate original return. Additional slips are shown in an XML file with report type code "O".

Cancelled slips
These are slips that were filed but must be removed. Cancelled slips are shown in an XML file with report type code "C" and in the summary with report type code "A".

Amended slips
These are slips that include changes to slips already filed. Amended slips and the summary are shown in an XML file with report type code "A". Remember to remove the slips with no changes as only the slips that need correction are to be submitted.

• An amended return can contain amended or cancelled slips, but it cannot contain original slips.
• The summary and the T619, Electronic Transmittal, record must show a report type code "A". They cannot show a report type code "O".
• The file must be in Extensible Markup Language (XML) format as specified in the XML specifications.
• Save the file on hard medium (DVD, CD, or diskette) and sent to:

  Electronic Media Processing Unit
  Ottawa Technology Centre
  Canada Revenue Agency
  875 Heron Road
  Ottawa ON K1A 1A2

See the types of information returns that can be amended or cancelled electronically.
