Key facts

  • The ISP1000 paper form cannot be submitted electronically — print it, sign it, and mail it (or drop it off at a Service Canada Centre).
  • Most people can skip paper entirely by applying online through My Service Canada Account (MSCA) — usually the fastest route.
  • Ontario uses two addresses: postal codes starting with L, M or N mail to Scarborough; K or P mail to Timmins.
  • If you worked in Quebec only, you likely contribute to the QPP, not the CPP — apply to Retraite Québec instead.
  • Skip the printer and the post office: PostPal prints your ISP1000 and deposits it with Canada Post the next business day — $6 flat.

How to mail it, step by step

  1. 1

    Decide between online and paper

    If you have a My Service Canada Account, applying online is faster and confirms receipt instantly. Use the paper ISP1000 if you cannot apply online — for example, if you are receiving or have applied for certain other CPP benefits, or live outside Canada.

  2. 2

    Complete and sign form ISP1000

    Fill in your Social Insurance Number, choose your pension start date, complete the direct-deposit section, and sign the form. An unsigned application will be returned.

  3. 3

    Match your province to a regional address

    Use the cards above. Ontario residents check the first letter of their postal code (L/M/N → Scarborough, K/P → Timmins). If you live outside Canada, use the province where you last resided.

  4. 4

    Mail it or drop it off

    Mail the signed form to your regional office, or hand it in at any Service Canada Centre. No printer? Upload the PDF to PostPal — $6 flat, printed and deposited with Canada Post the next business day.

Common questions

Can I submit the CPP paper application electronically?

No. The ISP1000 paper form cannot be emailed or uploaded — it must be printed, signed, and either mailed to your regional Service Canada office or dropped off at a Service Canada Centre. If you want a fully digital process, apply online through My Service Canada Account instead.

Should I apply online or by mail?

Online through My Service Canada Account is the recommended route for most people — it is faster and gives instant confirmation. Use the paper ISP1000 only if you cannot apply online, such as when you live outside Canada or your situation requires a paper application.

Where do Ontario residents mail the ISP1000?

It depends on your postal code. If it starts with L, M or N, mail to Service Canada, PO Box 5100, Station D, Scarborough ON M1R 5C8. If it starts with K or P, mail to Service Canada, PO Box 2013, Station Main, Timmins ON P4N 8C8.

How far ahead of my retirement date should I apply?

Service Canada recommends applying well before you want your pension to start — paper applications take longer to process than online ones. You can choose a start date up to 12 months in the future, so mail early rather than late.

I worked in Quebec — do I still mail this to Service Canada?

If you only ever contributed in Quebec, you are likely covered by the Quebec Pension Plan (QPP) and should apply through Retraite Québec instead. If you contributed to both plans, you generally apply based on where you live: Service Canada if you live outside Quebec, Retraite Québec if you live in Quebec.

Can PostPal print and mail my CPP application?

Yes. Upload your completed and signed ISP1000 as a PDF and PostPal prints it, envelopes it, and deposits it with Canada Post the next business day — $6 flat, with an emailed confirmation when it is handed to Canada Post.
