Service Canada mails T4A(P) and T4A(OAS) tax slips by the last day of February following the tax year they cover, so most recipients see them arrive by mid-March. You can usually get them a little sooner by downloading the PDF from your My Service Canada Account as soon as it’s posted. For the 2025 tax year, slips must be in the mail by the end of February 2026, and your return is due April 30, 2026.
When the Paper Slips Go Out
The Canada Revenue Agency requires most tax information slips, including T4A(P) for CPP benefits and T4A(OAS) for Old Age Security, to be sent to recipients by the last day of February following the tax year.1Canada Revenue Agency. Tax Slips – Personal Income Tax For 2025 income, that means Service Canada must have your slip in the mail by the end of February 2026.
Actual delivery depends on Canada Post. A one- to two-week transit window after mailing is typical, so most people receive their slips in the first half of March. If yours hasn’t arrived by late March, that’s the point to check online or ask for a replacement.
Downloading Your Slips Online
The fastest option is to pull your slips from My Service Canada Account. The online copies are generally posted before the paper versions land in your mailbox, and they are valid for filing your return. The portal lets you view, download, and print both T4A(P) and T4A(OAS) slips for the current and previous years.2Government of Canada. Contact Canada Pension Plan
Once you’re signed in, go to the tax slips section, select the year, and download the PDF. It takes a few minutes. The same slips also show up in CRA My Account, but the official downloadable versions come from the Service Canada side.
If You Don’t Have an Account Yet
Registration requires your Social Insurance Number and identity verification. You can sign in with an Interac Sign-In Partner using online banking credentials from a participating Canadian bank, with a GCKey username and password, or with an Alberta.ca Account or BC Services Card.3Government of Canada. Create a My Service Canada Account
To verify your identity, you can use a Personal Access Code (a 7-digit code from Service Canada), your SIN application number, or Interac verification through a participating bank. If you need a PAC and don’t have one, requesting it online means waiting five to ten business days for it to arrive by mail, or you can request it in person at a Service Canada location. Plan for that timeline. Starting a PAC request in late March when you’re already chasing a missing slip stacks one delay on top of another.
Filing When the Slip Hasn’t Arrived
You don’t have to wait for a missing slip to file on time. The CRA lets you estimate your income using bank statements, direct deposit records, or payment stubs. Include a note with your return identifying the issuer (Service Canada), the type of income, and what you’re doing to get the slip. If you file electronically, keep that documentation in case the CRA asks for it. If you file on paper, attach copies of your records and the note.4Canada Revenue Agency. Get a Copy of Your Slips
The filing deadline doesn’t shift because a slip is late. For most people, the 2025 return is due April 30, 2026. Self-employed filers have until June 15, 2026, though any balance owing is still due April 30.5Canada Revenue Agency. What You Need to Know for the 2026 Tax-Filing Season Filing late when you owe money triggers a penalty of 5% of the balance, plus 1% for each full month the return is late, up to 12 months.6Canada Revenue Agency. Interest and Penalties on Late Taxes A missing slip is not accepted as a reason to waive that penalty, so estimating and filing on time is the safer move.

The reprint arrives by mail, so you’re looking at another wait, and processing times vary with call volume.

Non-Residents Get an NR4 Instead
If you live outside Canada and receive CPP or OAS, you won’t get a T4A(P) or T4A(OAS). You’ll get an NR4 slip showing the amounts paid and any non-resident tax withheld. The mailing deadline is the last day of March following the tax year rather than the end of February, and it shifts to the next business day if March 31 falls on a weekend or public holiday.9Canada.ca.

The NR4 is not currently available through My Service Canada Account the way the domestic slips are, so non-residents who haven’t received theirs should contact Service Canada directly using the international numbers.
