A Canadian T4A(OAS) tax slip, or Statement of Old Age Security, is issued by Service Canada to tell you and the Canada Revenue Agency (CRA) how much old age security income you received during a tax year and the amount of income tax that was deducted.
Deadline for T4A(OAS) Tax Slips
T4A(OAS) tax slips must be issued by the last day of February the year after the calendar year to which the T4A(OAS) tax slips apply.

Filing T4A(OAS) Tax Slips With Your Income Tax Return
When you file a paper income tax return, include copies of each of the T4A(OAS) tax slips you receive. If you file your income tax return using NETFILE or EFILE, keep copies of your T4A(OAS) tax slips with your records for six years in case the CRA asks to see them.
Missing T4A(OAS) Tax Slips
If you do not receive your T4A(OAS) tax slip, contact Service Canada at 1-800-277-9914 during regular business hours. You will be asked for your Social Insurance Number.
Even if you haven't received your T4A(OAS) tax slip, file your income tax return by the deadline anyway to avoid penalties for filing your income taxes late. Calculate your OAS income and any related deductions and credits you can claim as closely as you can using any information you have. Include a note saying what you have done to get a copy of the missing T4A(OAS) tax slip. Include copies of any statements and information you used in calculating the income and deductions for the missing T4A(OAS) tax slip.
