Before you apply for citizenship, make sure you’re eligible.
Follow all of the application steps to become a Canadian citizen.
1. Get an application package
If you’re applying for citizenship for yourself or your child, use the correct application package:
- adults (age 18 or older)
- minors (under age 18)
- you can apply for your children:
- at the same time you apply for yourself or
- after you have become a citizen
- Canadian Armed Forces fast-track process
The application package includes the instruction guide and all the forms you need to fill out. Use the instruction guide and the document checklist to make sure you don’t miss anything.
When you done filling out the application, gather everything else you need, including:
- documents (copies or originals as stated in the document checklist)
- fee payment
- postal codes for all Canadian and overseas addresses
2. Pay the application fees
You must pay the application fees:
- in Canadian funds
- online (we don’t accept other payment methods)
We won’t refund your processing fees (or your children’s, if you’re applying for them) after we start processing your application(s).
If you’re sending all of your family’s application forms in the same envelope you can use one payment receipt for all of them.
The instruction guide has more detailed information on fees.
3. Submit your application
You must be eligible to apply for Canadian citizenship the day before you sign the application form or earlier. We’ll send your application back to you if you date it:
- in the future
- more than three months before we get it
Send your completed application form, along with all the documents on the checklist, by mail or courier.
If your application is incomplete or missing information, we will return it to you. We will ask you to send it again with the missing information included.
Sending more than one application
If you’re applying for more than one person and want us to process your applications at the same time, put all the forms and documents in the same envelope. If there are issues with one of the applications, we may continue to process the rest. If you send the applications in different envelopes, we’ll process them one at a time.
