If your Canada study visa expires, you must stop studying immediately and either apply for an extension or leave the country. Overstaying without authorization can result in legal consequences, including deportation and a ban on re-entering Canada.
To extend your stay, submit a renewal application before the expiry date. Include proof of enrollment, financial stability, and a valid passport. If your visa expires while your extension is processing, you may stay under implied status until a decision is made.
Failing to comply with visa regulations can negatively impact future applications for visas, permits, or permanent residency in Canada.
