You need the right documents to re-enter Canada if you leave, so be sure to check your document expiration dates and renew them if necessary before you travel.
Learn what immigration documents you need to return to Canada and what documents to bring by visiting the Travelling to Canada guide.
In general, it’s best to renew your immigration documents before you leave Canada, if possible. If your immigration document(s) will expire while you are outside Canada, or you’ve applied for an extension of your document(s) before they expired and must leave Canada, contact International Student Advising before travelling for support.
If you’ve applied for a study permit extension before it expired and your application is still being processed, you will lose maintained status when you leave Canada and will not be able to resume studies until your study permit has been issued. Check maintained status to learn more.
Check Immigration, Refugees and Citizenship Canada (IRCC)'s estimated processing times to plan ahead.
