Yes, you can apply to extend your stay in Canada as a visitor before your current status expires. If approved, you will receive a Visitor Record, which is not a visa but proof of your new status and extended stay conditions. Extensions are decided by IRCC and must be applied for online. Applications should be submitted at least 30 days before your current visa expires. Approval is not automatic; you must show sufficient funds, reasons for extension (tourism, family visit, etc.), and compliance with visa conditions. Overstaying may affect future visa applications.
