Yes, to help you meet the income requirement to sponsor your parents and grandparents, your co-signer can be your:

• spouse or
• common-law partner

Regardless of how long you’ve been married or in a common-law relationship:

• your spouse or common-law partner can be your co-signer
• your co-signer must provide proof of income for the last 3 taxation years before the date of your application

As your co-signer, your spouse or common-law partner must:

• meet the same eligibility requirements as you, the sponsor
• agree to, for a period of time, financially take care of and provide for the basic needs of the persons you’re sponsoring

You and your co-signer are equally liable if these obligations aren’t performed.

To prove you, as the sponsor and co-signer, meet the income requirements, you must include your notice of assessment from the Canada Revenue Agency (CRA) for the last 3 tax years before you apply. The easiest way to prove your income is to give IRCC permission to get your notices of assessment directly from the CRA.

Please Note: Your sibling CANNOT co-sign the PGP sponsorship application.
