Can I continue staying in Canada after I submit my study permit extension application?

As long as IRCC receives your study permit extension application before the expiration date of your current study permit, you will have maintained status (formerly known as implied status) to stay in Canada until IRCC has finalized your application.  You may also continue studying (and working, if meeting the eligibility requirements) under the same conditions you were previously studying/working under while you await processing, even if your study permit expires while you wait. 

Note that maintained status is only applicable in Canada. If you travel outside of Canada, and your study permit expires while you are away, you may not resume your study or work until your study permit extension application has been approved and you meet the requirements. 

For more information about maintained status, visit the IRCC website.
