Sponsorship of a spouse, common-law partner, conjugal partner or dependent child living outside Canada — Part 1: The sponsor’s guide (IMM 3900)

Mailing your application

Gather the forms for the person you are sponsoring and for his/her dependents, if applicable. Ensure that the required forms are completed, signed, where applicable and accompanied by the supporting documents. Have them return all the forms and supporting documents to you and send them with your forms along with all the supporting documentation to CPC-M. Do not forget to include a copy of your receipt. CPC-M’s mailing address is:

Case Processing Centre - Mississauga
P.O. Box 3000, Station A
Mississauga ON  L5A 4N6

The envelope will require more postage than a normal letter. To avoid having your application returned to you, have the post office weigh it before mailing.

Should you require confirmation that your application arrived at destination, contact your local postal outlet for information on various mailing options available to you.

Unless notified otherwise, advise CPC-M immediately, by mail or facsimile (905 803-7392) if, following the submission of your application, there are any changes to your family status such as marriage, divorce, births, deaths, your address or telephone/fax number, or any other important information. When advising the office of such changes, you must clearly state your file number, which will be found at the top of any correspondence CPC-M will send you to acknowledge the receipt of your application.

If you move

If your address changes after you have submitted your application, let us know immediately:

  • by e-mail, using CIC’s online service. Just go to CIC’s website and follow the instructions for filling out and submitting the electronic change of address form; or
  • by telephone, by contacting our Call Centre.

For Canadian citizens living exclusively outside Canada, write or fax to CPC-M.

Sponsors who signed an “engagement” with the province of Quebec and subsequently move from Quebec to another province in Canada while their sponsorship application is in process must sign a new undertaking and agreement. Conversely, sponsors who signed an undertaking with the Minister of Citizenship and Immigration and subsequently move to Quebec from another province in Canada while their sponsorship application is in process must sign an “engagement” with the province of Quebec.
