How to mail it, step by step
- 1
Check whether the form can go through the online portal
Log in to your NSLSC account first — many forms, including RAP applications, can be submitted electronically, which is faster than mail. Use paper when the form requires a wet signature, when you cannot access the portal, or when the NSLSC has asked you to mail something.
- 2
Complete and sign the form
Fill in every required field and sign where indicated. For a RAP application, include any required proof of income; for a consent withdrawal, make sure the names and loan details match your account exactly. Incomplete forms get mailed back, which can cost you weeks.

Mail it and watch your enrolment dates
If you are applying for RAP, remember it only covers a 6-month period — set a reminder to reapply before it lapses so your payments do not restart unexpectedly. Upload your form to PostPal and we print it and hand it to Canada Post the next business day, $6 flat.
Common questions
Where do I mail my Repayment Assistance Plan (RAP) application?
To the National Student Loans Service Centre, P.O. Box 4030, Mississauga ON L5A 4M4. You can also apply through your NSLSC online account, which is usually faster. Either way, include any income documentation the application asks for.
How often do I need to reapply for RAP?
Every 6 months. RAP enrolment runs in 6-month periods, and approval does not roll over automatically. If you still need help with payments when your period ends, submit a new application before it lapses so there is no gap in coverage.
Can I submit NSLSC forms online instead of mailing them?
Often, yes. The NSLSC secure online portal accepts many forms, including RAP applications, and it is the fastest route. Mail the paper version to P.O. Box 4030, Mississauga ON L5A 4M4 when a form is not available online, needs an original signature, or when the NSLSC specifically asks for it by mail.
Where do I send a withdrawal of consent for my student loan file?
Mail your signed consent withdrawal to the National Student Loans Service Centre, P.O. Box 4030, Mississauga ON L5A 4M4. Make sure the personal details on the form match your loan account so the NSLSC can locate your file without follow-up.
Is there a phone number I can call before mailing something?
Yes — the NSLSC line is 1-888-815-4514. Calling first is a good idea if you are unsure whether your form can be submitted online or whether any supporting documents are required, since an incomplete mailing will be returned to you.
I do not have a printer — how do I get my form to the NSLSC?
Upload the completed PDF to PostPal: $6 flat, printed and deposited with Canada Post the next business day, no account needed. We address the envelope to P.O. Box 4030, Mississauga ON L5A 4M4 and email you confirmation when it is handed to Canada Post.
