If you are filing on paper, use the T4A Summary, Summary of Pension, Retirement, Annuity, and Other Income, to report the totals of the amounts that you reported on the T4A slips. Send the original T4A summary and the related slips to:
Ottawa Technology Centre
Canada Revenue Agency
875 Heron Road
Ottawa ON K1A 1G9
If the total number of T4A slips you file is more than 50 slips for the same calendar year, you have to file them over the Internet.
For detailed completion instructions, go to Detailed T4A Summary instructions.
Report amounts in Canadian dollars and cents, even if they were paid in another currency. To get the average exchange rates, go to What are the average exchange rates?
Complete a separate T4A summary for each of your payroll accounts. The totals you report on your T4A Summary have to agree with the totals you report on your T4A slips. Errors or omissions can cause unnecessary processing delays
