Adding T3 slips
After you file your T3 return, you may discover that you need to send us more T3 slips. If you have original slips that were not sent with your return, send them either electronically or on paper.
Adding slips over the Internet
To send T3 slips over the Internet, use either the Internet file transfer or Web Forms services. Identify additional slips with report type code "O." For more information, see Filing Information Returns Electronically.
Adding slips on paper
If you send additional slips on paper, clearly identify the new slips by writing "ADDITIONAL" at the top of the slip. Send one copy of the additional slips to any tax centre. Do not file an additional summary.
Notes
If the total number of T3 slips (including any additional slips) you file is more than 50 for the same calendar year, you have to send the additional slips over the Internet.
Any additional T3 slips that are sent after the due date may result in a penalty. For more information, see Penalty for failure to file an information return by the due date.
