Canada allows tourists to extend their stay in the country before their current visa expiration date. You need to submit a Visitor Record application at least 30 days before your visa ends to stay legally while your request is pending. The extension request needs a payment of CAD 100. All extension applications require detailed explanations of your visit extension reasons with proper supporting documentation such as updated financial statements and travel plans. An official Visitor Record does not provide re-entry permission for Canada after exiting the country.
