I am on super visa in Canada.?
You should be able to by contacting your country's consulate or embassy. They should have a website detailing the procedure to renew your passport. Once renewed, you may need to apply for a new SuperVisa as visas are often linked to a passport and expire when the passport expires. Check the expiry date in your visa. It will not be necessary to apply for a new visa until after you leave Canada following the expiry of your current visa.
