What is ISP-1603 CPP/OAS consent?

Your CPP and OAS information is confidential. The form's instruction sheet says Service Canada cannot discuss your benefits with your spouse, common-law partner, son or daughter without your signed consent. Form ISP-1603 is that consent: you name a person, and Service Canada can then share your program information with them and act on information they give.

The authorized person can give and receive information such as benefit rates, address changes (not the payment address), tax slips, OAS income, Canadian residence information and CPP contributions. They cannot apply for benefits, withdraw or cancel them, change where your payment goes, or request or change voluntary tax withholding. For that, Service Canada needs a legal representative such as a power of attorney or trustee.

FileIt walks you and the person you name through the two sections, prints the answers into Service Canada's own PDF (names with accents print correctly) and saves it in your vault. Both of you sign. FileIt never sends the form to Service Canada; you do.

How to fill out ISP-1603 CPP/OAS consent, step by step

1 Section 1 — Your consent

Give your first name, initial, family name and SIN, tick the programs the consent covers, then sign and date. Your signature confirms you understand that the consent doesn't let the person apply for benefits or change your payment address or tax withholding, stays valid until you cancel it in writing, and is only valid if Service Canada receives the form within one year of the date you sign it.

2 Section 2 — The authorized person

The person you name gives their name, relationship to you, home, work and other phone numbers, and mailing address on one line. They sign and date to confirm they understand what they can and cannot do on your behalf.

3 Section 3 — Witness (only if needed)

If you sign Section 1 with a mark such as an X, a witness such as a friend or family member completes this section and signs. The witness cannot be the person named in Section 2.

Common mistakes to avoid

  • Leaving all three program boxes empty. Tick every program the person should be able to discuss.
  • Expecting the form to let your helper apply for benefits, change your bank account or change tax withholding. It explicitly does not.
  • Holding on to the signed form. It only works if Service Canada receives it within one year of the date you sign.
  • Having the authorized person also act as the witness.
  • Forgetting the second signature: the authorized person must complete and sign Section 2.

After you fill it out

Print the PDF. You sign and date Section 1 and the authorized person signs and dates Section 2 (and a witness signs Section 3 if you signed with a mark). Then send it to Service Canada.

Keep the filled copy in your FileIt vault, and give the authorized person a copy so they know what they may discuss.

To end the consent, the instruction sheet says to send Service Canada a written cancellation. It also ends on your death.

Remember that the note on the form says third parties can't use Service Canada's online services, so your helper will deal with Service Canada by phone or in writing. The instruction sheet lists 1-800-277-9914 (English) and 1-800-277-9915 (French) in Canada and the United States.

ISP-1603 CPP/OAS consent: frequently asked questions

Does my spouse or adult child need this form to talk to Service Canada for me?

Yes. The instruction sheet says Service Canada cannot communicate your personal benefit information with your spouse, common-law partner, son or daughter without your signed consent.

Can the authorized person apply for benefits or change my direct deposit?

No. The consent does not let them apply for, withdraw or cancel benefits, change your payment address or bank account, or request or change voluntary tax withholding. Generally only you, or a legal representative such as someone with your power of attorney or a trustee, can change payment details.

How long does the consent last?

Until you cancel it in writing, or on your death. It is only valid if Service Canada receives the form within one year from the date you sign it.

What if I already have a power of attorney?

The form says that if Service Canada's records show a legal representative, such as a power of attorney or trustee, is authorized to act for you, all communications will be made through that legal representative.

Can the authorized person use My Service Canada Account for me?

No. The form notes that third parties are not currently authorized to use Service Canada's online services.

When do I need a witness?

Only if you sign Section 1 with a mark. The witness, for example a friend or family member, completes Section 3 and cannot be the person named in Section 2.

Can I fill out ISP-1603 online with FileIt?

Yes. FileIt prints both sections into Service Canada's official PDF and saves it in your vault. You and the authorized person then sign it, and you send it to Service Canada yourself.
